AVR109: support for prodsig read and usersig read/write
2022-10-05 22:20:16 +01:00
Stefan Rueger d74b17b9b4
Provide cached byte-wise read/write API (#1106)
* Provide cached byte-wise read/write API

int avr_read_byte_cached(const PROGRAMMER *pgm, const AVRPART *p, const
  AVRMEM *mem, unsigned long addr, unsigned char *value);

int avr_write_byte_cached(const PROGRAMMER *pgm, const AVRPART *p, const
 AVRMEM *mem, unsigned long addr, unsigned char data);

int avr_flush_cache(const PROGRAMMER *pgm, const AVRPART *p);

int avr_chip_erase_cached(const PROGRAMMER *pgm, const AVRPART *p);

int avr_reset_cache(const PROGRAMMER *pgm, const AVRPART *p);

avr_read_byte_cached() and avr_write_byte_cached() use a cache if paged
routines are available and if the device memory is EEPROM or flash,
otherwise they fall back to pgm->read_byte() and pgm->write_byte(),
respectively. Byte-wise cached read always gets its data from the cache,
possibly after reading a page from the device memory. Byte-wise cached
write with an address in memory range only ever modifies the cache. Any
modifications are written to the device after calling avr_flush_cache() or
when attempting to read or write from a location outside the address range
of the device memory.

avr_flush_cache() synchronises pending writes to EEPROM and flash with the
device. With some programmer and part combinations, flash (and sometimes
EEPROM, too) looks like a NOR memory, ie, one can only write 0 bits, not 1
bits. When this is detected, either page erase is deployed (eg, with parts
that have PDI/UPDI interfaces), or if that is not available, both EEPROM
and flash caches are fully read in, a pgm->chip_erase() command is issued
and both EEPROM and flash are written back to the device. Hence, it can
take minutes to ensure that a single previously cleared bit is set and,
therefore, this routine should be called sparingly.

avr_chip_erase_cached() erases the chip and discards pending writes() to
flash or EEPROM. It presets the flash cache to all 0xff alleviating the
need to read from the device flash. However, if the programmer serves
bootloaders (pgm->prog_modes & PM_SPM) then the flash cache is reset
instead, necessitating flash memory be fetched from the device on first
read; the reason for this is that bootloaders emulate chip erase and they
won't overwrite themselves (some bootloaders, eg, optiboot ignore chip
erase commands altogether) making it truly unknowable what the flash
contents on device is after a chip erase. 

For EEPROM avr_chip_erase_cached() concludes that it has been deleted if a
previously cached EEPROM page that contained cleared bits now no longer
has these clear bits on the device. Only with this evidence is the EEPROM
cache preset to all 0xff otherwise the cache discards all pending writes
to EEPROM and is left unchanged otherwise.

Finally, avr_reset_cache() resets the cache without synchronising pending
writes() to the device.

Offload the programming interface info from part->flags to part->prog_modes
flags now just hold parameters of the JTAG interface and some secondary
serial, parallel, pseudo parallel info. This separation brings clarity. It
used to be hard to augur whether a part has an ISP interface:

   (part->flags & (AVRPART_HAS_PDI | AVRPART_AVR32 | AVRPART_HAS_TPI
    | AVRPART_HAS_UPDI)) == 0 && (part->flags & AVRPART_SERIALOK) != 0

or had HVSP or HVPP capability, for that matter. Now it is just, eg,

  part->prog_modes & PM_ISP
  part->prog_modes & PM_HVPP

     + PM_SPM: Bootloaders, self-programming with SPM/NVM Controllers
     + PM_TPI: t4, t5, t9, t10, t20, t40, t102, t104

     + PM_debugWIRE: Simpler alternative to JTAG (a subset of HVPP/HVSP parts)
     + PM_JTAG: some classic parts, some xmega
     + PM_aWire: AVR32 parts
 - Add mcuid, a unique id in 0..2039, to part definition for urclock programmer
 - Add n_interrupts, the number of interrupts, to part definition
 - Add n_page_erase to part definition (# of pages erased during NVM erase)

 - Implement a simple calculator in config_gram.y so numeric values can be
   expressed as simple expressions such as PM_SPM | PM_UPDI

 - Introduce a new method of assigning simple components to the grammar without
   touching config_gram.y via an eligible-component list in config.c; numeric
   expressions on the rhs of an assignment resolve to integer values

 - Update documentation in avrdude.conf.in and avrdude.texi

Although the avrdude.conf file has changed much, the internal

exporting the raw internal data through

  avrdude -c*/r -p*/r >/tmp/avrdude.raw

before the change and by comparing again after the change:

Replace loop/if condition and reduce signed comparison warnings in avrftfi.c
Change (int) poll_index >= (int) addr to poll_index+1 > addr as the former
might turn out to be implementation-defined. The latter is always defined
and what we want here (poll_index+1 won't overflow). Originally, the
condition was poll_index > addr-1, which was always false for addr=0 owing to
2^n modulo arithmetic of unsigned.

Also changed a few comparisons so they no longer are between signed
and unsigned integers reducing compiler warnings.

Use const in PROGRAMMER function arguments where appropriate
In order to get meaningful const properties for the PROGRAMMER, AVRPART and
AVRMEM arguments, some code needed to be moved around, otherwise a network of
"tainted" assignments risked rendering nothing const:

 - Change void (*enable)(PROGRAMMER *pgm) to void (*enable)(PROGRAMMER *pgm,
   const AVRPART *p); this allows changes in the PROGRAMMER structure after
   the part is known. For example, use TPI, UPDI, PDI functions in that
   programmer appropriate to the part. This used to be done later in the
   process, eg, in the initialize() function, which "taints" all other
   programmer functions wrt const and sometimes requires other finessing with
   flags etc. Much clearer with the modified enable() interface.

 - Move TPI initpgm-type code from initialize() to enable() --- note that
   initpgm() does not have the info at the time when it is called whether or
   not TPI is required

 - buspirate.c: move pgm->flag to PDATA(pgm)->flag (so legitimate
   modification of the flag does not change PROGRAMMER structure)

 - Move AVRPART_INIT_SMC and AVRPART_WRITE bits from the flags field in
   AVRPART to jtagmkII.c's private data flags32 fiels as FLAGS32_INIT_SMC and
   FLAGS32_WRITE bits

 - Move the xbeeResetPin component to private data in stk500.c as this is
   needed by xbee when it saddles on the stk500 code (previously, the flags
   component of the part was re-dedicated to this)

 - Change the way the "chained" private data are used in jtag3.c whilst
   keeping the PROGRAMMER structure read-only otherwise

 - In stk500v2.c move the STK600 pgm update from stk500v2_initialize() to
   stk500v2_enable() so the former keeps the PROGRAMMER structure read-only
   (for const assertion).

 - In usbasp change the code from changing PROGRAMMER functions late to
   dispatching to TPI or regular SPI protocol functions at runtime; reason
   being the decision whether to use TPI protocol is done at run-time
   depending on the capability of the attached programmer

Also fixes Issue #1071, the treatment of default eecr value.

brutzzl3r 266eb23207 man-page: Fix install dir
`avrdude.1` is installed into `man` dir instead of its proper section
location.
This is due to the definition of `TYPE MAN` which points to
`<DATAROOT>/man` according to cmake docs.

Use `DESTINATION` and add proper section subdir.

This allows for `man -M <YOUR INSTALL dir>/share/man -w 1 avrdude` to succeed
instead of throwing `No manual entry for avrdude in section 1`

Replace string arrays with const char * and allocated space (part 2)
This commit replaces fixed-string buffers in PROGRAMMER, AVRPART and AVRMEM
that are dealt with by the parser and grammar. Now, string assignments are
always to const char *, ie, these are read-only strings with arbitrary
length.

config_gram.y now only needs to consider one type of string assignment.

This commit also

  - Replaces the simple linear-search cache_string() function with faster
    hashed cache_string(). Either way, the returned value is likely to be
    shared, so should never be free()'d.

  - Duplicates hvupdi_support list in pgm_dup() and frees it in pgm_free()

  - Adds const qualifier to some function args in avrpart.c and pgm.c

  - Hardens some functions against being called with NULL pointers

  - Ensures _new() and _dup() functions for parts, programmers and memory
    return a suitable memory. Out of memory triggers exit in one of three
    functions, cfg_malloc(), cfg_realloc() and cfg_strdup(); there is
    rarely anything useful that AVRDUDE or, for that matter, any
    application compiled against libavrdude can do once you run out of
    memory as AVRDUDE/libavrdude rely heavily on allocation of memory.

Implement a dry run for -U updates before opening the programmer
This commit checks -U update requests for
  - Typos in memory names
  - Whether the files can be written or read
  - Automatic format detection if necessary

before opening the programmer. This to reduce the chances of the
programming failing midway through.

Minor additional changes:
  - Give strerror() system info when files are not read/writeable
  - Lift the auto detection message from MSG_INFO to MSG_NOTICE
  - Provide fileio_fmt_autodetect() in the AVRDUDE library
  - Rename fmtstr() in the AVRDUDE library to fileio_fmtstr() to
    avoid name clashes when an application links with it

Example:

$ avrdude -U - -U typo:r:.:h -U eeprom:w:testin:r -p ... -c ...
avrdude: can't auto detect file format for stdin/out, specify explicitly
avrdude: unknown memory type typo

Stefan Rueger 3412196cd9 Weaken -U memory type check and move after config file parsing in main.c
The check for typos in -U memory names against a list of known memory names
now happens after the config files have been read, so newly declared memory
names can be considered. This commit also weakens the check against existence
of a known memory: it is now sufficent for a name to pass when it could be
the initial string of any known memory of any part. Any -U memory that cannot
possibly be matched up with a known memory is considered a typo and leads to
an exit before the programmer is opened.

This to protect users from typos that leave a device partially programmed.

When every -U memory name might be matching one of the known memories, the
programming is attempted. If the part to be programmed turns out not to have
a particular -U memory, AVRDUDE warns the user and skips this -U update.

This to support unifying interfaces that call AVRDUDE with potentially more
memories than the actual part has (eg, efuse on ATmega8).

Stefan Rueger 02027ab766 Enable stdin verification and display correct number of bytes written/verified
Counting the number of bytes written to a memory and/or verified is not
trivial owing to potential holes in the input file and to potential trailing
0xff bytes in flash memory that are not written per default (but see -A). The
new function memstats(), which is best called just after an input file has
been read into mem->buf/mem->tags, computes the right number of bytes written
and allows easy computation of the number of bytes verified.

This commit also changes the strategy for the default verification after
writing to a chip memory, so that the input file only needs reading once thus
enabling successful verification of stdin input files.

Other, minor changes:
 - Improving the grammar of AVRDUDE output, eg, 1 byte written instead of
   1 bytes written
 - Better description of the input file structure in terms of its sections,
   the interval it spans, the number  of pages, the number of padding bytes
   in pages, and the number of actually cut off trailing 0xff bytes for flash
 - Printing <stdin> or <stdout> instead of - in the -U routines
 - Option -V no longer needs to be specified before option -U in order to work

As an aside this commit also provides useful helper functions for printing
plural(), inname(), outname() and interval() all of which return strings fit
for printing.

Deprecate original STK500 v1 protocol in favour of optiboot and Arduino as ISP
For paged read/write early AVRDUDE implementations of the STK500 v1 protocol
communicated a word address (below a_div=2) or byte address (a_div=1) based
on the following code irrespective of which memories were used:

  if(m->op[AVR_OP_LOADPAGE_LO] || m->op[AVR_OP_READ_LO])
    a_div = 2;
  else
    a_div = 1;

This turned out to be a bug: it really should have been a_div=2 for flash and
a_div=1 for eeprom. At the time presumably no one noted because Atmel was at
the cusp of replacing their FW 1.x with FW 2 (and the STK500 v2 protocol).

It seems that the world (optiboot, Arduino as ISP, ...) has compensated for
the bug by assuming AVRDUDE sends *all* eeprom addresses as word addresses.
Actually these programmers overcompensated for the bug because for six out of
the 146 known SPI programmable parts with eeprom and page size > 1, AVRDUDE
would still send the eeprom addresses as byte addresses (ATmega8 ATmega8A
ATmega64 ATmega64A ATmega128 ATmega128A) owing to above code.

It makes no sense to correct the bug now seeing that virtually no one uses
the old 2005 STK 500 v1 firmware. This commit now follows optiboot, Arduino
as ISP and other projects, and simply sends all addresses for paged read or
write as word addresses. There are no longer (little known) exceptions for
ATmega8 et al that surprised some optiboot etc users.

Stefan Rueger 572849ec2a Provide avr_set_addr_mem() to set addresses in SPI opcodes within boundaries
The function avr_set_addr_mem(AVRMEM *mem, int opnum, unsigned char *cmd,
unsigned long addr) is meant to replace avr_set_addr(OPCODE *op, unsigned
char *cmd, unsigned long addr) in future.

avr_set_addr_mem() has more information about the context of the task in that
it knows the memory size, memory page size, whether or not the memory is a
flash memory (which gets words addressees supplied) and, crucially, knows
which SPI operation it is meant to compute the address bits for.

avr_set_addr_mem() first computes the interval of bit numbers that must be
supplied for the SPI command to stand a chance to work. The function only
sets those address bits that are needed. Once all avr_set_addr() function
calls have been replaced by avr_set_addr_mem(), the SPI commands that need an
address can afford to declare in avrdude.conf all 16 address bits in the
middle two bytes of the SPI command. This over-declaration will be corrected
during runtime by avr_set_addr_mem(). One consequence of this is that parts
can inherit smaller or larger memories from parents without the need to use
different SPI codes in avrdude.conf. Another consequence is that
avr_set_addr_mem() can, and does, tell the caller whether vital address bits
were not declared in the SPI opcode. During parsing of avrdude.conf this
might be utilised to generate a corresponding warning. This will uncover
problematic SPI codes in avrdude.conf that in the past went undetected.

Stefan Rueger 30041e3f5f Add compact alternative specification for SPI opcodes in avrdude.conf
As the address bit numbers in the SPI opcodes are highly systematic, they
don't really need to be specified. Each bit can therefore be described as one
of the characters 0 (always 0), 1 (always 1), x (don't care, but will be set
as 0), a (a copy of the correct bit of the byte or word address of read,
write, load, pagewrite or load extended address command of memories with more
than one byte), i (input bit for a load/write) or o (output bit from a read).
The bits therefore do not need to be individually separated.

If a string in the list of strings that describe an SPI opcode does *not*
contain a space *and* is longer than 7 characters, it is interpreted as a
compact bit-pattern  representation. The characters 0, 1, x, a, i and o will
be recognised as the corresponding bit, whilst any of the characters ., -, _
or / can act as arbitrary visual separators, which are ignored. Examples:

  loadpage_lo = "0100.0000--000x.xxxx--xxaa.aaaa--iiii.iiii";

  loadpage_lo = "0100.0000", "000x.xxxx", "xxaa.aaaa", "iiii.iiii";

  loadpage_lo = "0100.0000", "000x.xxxx.xxaa.aaaa", "iiii.iiii";

  loadpage_lo = "0100.0000-000x.xxxx--xxaa.aaaa-iiii.iiii";

  loadpage_lo = "0100.0000/000x.xxxx/xxaa.aaaa/iiii.iiii";

The compact format is an extension of the current format, which remains
valid. Both, the compact and the traditional specification can be mixed in
different strings, albeit not in the same string:

  load_ext_addr = "0100.1101", "0000.0000.0000", "0 0 0 a16", "0000.0000";

Stefan Rueger db37c9d286 Extend rather than reset memory entries in avrdude.conf
This commit changes the philosophy whenever avrdude.conf encounters the
same memory of a part for the second time or whenever a memory is
described that, through inheritance, already existed: AVRDUDE no longer
zaps the memory, it rather extends it.

Therefore, avrdude.conf.in's entry for ATmega128RFA1, which inherits from
the ATmega2561, needs a line `load_ext_addr = NULL;` in its flash memory
description to zap the inherited load_ext_addr SPI command.

Other than this, avrdude.conf.in needs no other change in order to effect
the same internal representation proving earlier updates to the .conf.in
file correct that manually ensured inheritance of memory contents.

Stefan Rueger 8da9c2bbf6 Correct bit number for lone 'a' in config_gram.y
When an SPI command has a lone 'a' the initialisation now is as would be
expected by all commands that take an address. Atmel's opcodes for SPI
programming are consistent in this respect. This commit makes specifying
the bit number in avrdude.conf optional. Instead of

 read_lo = "0 0 1 0 0 0 0 0  0 0 a13 a12 a11 a10 a9 a8  a7 a6 a5 a4 a3 a2 a1 a0  o o o o o o o o";

one can now use

 read_lo = "0 0 1 0 0 0 0 0  0 0 a a a a a a  a a a a a a a a  o o o o o o o o";

Stefan Rueger f95a1d3448 Cache config_file components in AVRPART and PROGRAMMER structures
Some 90% of the space of AVRPART and some 50% of PROGRAMMER is occupied by a
4 kB array config_file[] that contains the configuration file name. In
preparation of developer options that output a raw dump of the part
descriptions, this commit changes the config_file components from a large
array, which is duplicated in each part and programmer description, to a
cached string for each config file allowing for smaller raw dumps.

This commit also changes the config file name to its realpath(), eg, shortens
unwarranted `/bin/../etc/` file name components. It also changes the global
variable names `infile` and `fileno` to cfg_infile and cfg_fileno for an ever
so slight improvement of code clarity.

The new file type I is essentially Intel HEX that, on download, inserts
comments next to data records with the resolved effective address and an
ASCII dump of that same record. On upload the `I` format is permissive
with respect to check sum errors, eg, after manipulated an Intel HEX file
for debugging.

Stefan Rueger d05ddd188d Fix usbtiny read/verify for parts with more than 64 kB flash
Usbtiny has a protocol or firmware problem that prevents it from reading
flash above 64 kB in page mode (used by -U flash:r:... and -U flash✌️...).
This commit fixes that problem by falling back on byte access for flash paged
reads above 64k. It also issues the correct load extended address command for
parts with more than 128 kB flash thus extending support to ATmega2560 et al.

Stefan Rueger 14b27726d4 Protect terminal dump from vagaries of C libray implementation of isalpha() etc
Some C libraries assign true to isalpha(0xff), isdigit(0xff) or
ispunct(0xff), which means that the Operating System terminal sees a
character 0xff which it may not have a useful display character for.

This commit only outputs printable ASCII characters for an AVRDUDE
terminal dump reducing the risk of the OS terminal not being able
to print the character properly.
