Brian S. Dean db1fd5124e Fix stk500 page write (Program Page command). This is supported after
all on non-paged-memory parts.  The problem was that the page size was
defaulting to 256 (maximum for the stk500), but the timeout for a
response from the stk500 before declaring it dead was only 0.5
seconds.  But it takes much longer than 0.5 seconds to program 256
bytes, so we just weren't waiting long enough.

Fix this in two ways - increase the timeout to 5 seconds, and decrease
the page size to 16 bytes for non-paged parts.  The programming time
for 16 bytes is short enough to provide the user with some feedback
that something is happening.

Brian S. Dean a61708b2b9 Don't call the programmer's 'paged_write' routine unless the memory
itself is paged as it doesn't appear to work otherwise.

Brian S. Dean 04da94efb9 Add the ability to read a per-user config file located at
$HOME/.avrduderc.  Entries from .avrduderc take precedence over those
from the system wide config file in ${PREFIX}/etc/avrdude.conf.

Track and display the config file name and line number when we print
out the available parts and programmers.  This is useful in case
someone has overridden a definition in their .avrduderc file and is
wondering why the definition in the system wide config file is not
being used.

Remove the default programmer 'stk500' from the distributed config
file.

Brian S. Dean 8ba95cd0c3 Add the ability to specify which pin to pulse when retrying entry into
programming mode.  Use 'retry_pulse' in the per-part specification
that can currently take values of 'reset' or 'sck', the default being
'sck' which preserves the previous behaviour.  Some newer parts
indicate that /RESET should be pulsed, while older parts say to pulse
SCK.

Brian S. Dean 0e9ef447a0 Add 'serial' and 'parallel' keywords to the grammar so that one can
say whether parts support these programming modes or not.  Possible
values for 'serial' are 'yes' or 'no'.  Possible values for 'parallel'
are 'yes', 'no', or 'pseudo'.  Add a bit mask of flags to the AVRPART
structure to capture these settings.  Use these within
stk500_initialize() to set the device parameters correctly.

Defaults for 'serial' and 'parallel' are 'yes' unless specified
otherwise.

Brian S. Dean 17427c0645 Change the name from AVRPROG to AVRDUDE.
This change represents a name change only.  There is currently an
effort to port AVRPROG to other platforms including Linux and Windows.
Since Atmel's programmer binary that's included within their AVR
Studio software is named AVRPROG.EXE on the Windows OS, there is the
chance for confusion if we keep calling this program AVRPROG as well.
Up until now the name hasn't really been a problem since there was no
chance to confuse 'avrprog' on Unix with Atmel's AVRPROG because
Atmel's tools only run on Windows.  But with the Unix 'avrprog'
possibly being ported to Windows, I felt a name change was the best
way to avoid problems.

So - from this point forward, my FreeBSD Unix program formerly known
as AVRPROG will subsequently be known as AVRDUDE (AVR Downloader/UploaDEr).

This change also represents a time when the AVRDUDE sources move from
my own private repository to a public repository.  This will give
other developers a chance to port AVRDUDE to other platforms and
extend its functionality to support additional programming hardware,
etc.

So goodbye AVRPROG, welcome AVRDUDE!

Fix setting of status LEDs under various write-fail conditions.

Add a flag to indicate that a memory type requires the device to
possibly be powered off and back on after a write to it.  This is due
to a hardware problem on some Atmel devices, see:

	http://www.atmel.com/atmel/acrobat/doc1280.pdf

Add greater verbosity to the part-display code when verbose>1 to
display avrprog's encoding of the defined programming instructions.
This is primarily for debugging purposes.

  * add the AT90S4414 part

  * add fuse and lock bit access instructions for the AT90S1200,
    AT90S4434, and AT90S8515.

2001-11-21 05:50:59 +00:00
Brian S. Dean fb233af934 This is a jajor re-write of the programming algorithms. The Atmel
serial programming instructions are not very orthoganal, i.e., the
"read fuse bits" instruction on an ATMega103 is an entirely different
opcode and data format from the _same_ instruction for an ATMega163!
Thus, it becomes impossible to have a single instruction encoding
(varying the data) across the chip lines.

This set of changes allows and requires instruction encodings to be
defined on a per-part basis within the configuration file.  Hopefully
I've defined the encoding scheme in a general enough way so it is
useful in describing the instruction formats for yet-to-be invented
Atmel chips.  I've tried hard to make it match very closely with the
specification in Atmel's data sheets for their parts.  It's a little
more verbose than what I initially hoped for, but I've tried to keep
it as concise as I could, while still remaining reasonably flexible.

Brian S. Dean f1af5d3981 Add support for ATMega163.
Add support for reading/writing ATMega163 lock and fuse bits.
Unfortunately, in looking at the specs for other ATMega parts, they
use entirely different instruction formats for these commands.  Thus,
these routines won't work for the ATMega103, for example.

Add support for sending raw command bytes via the interactive terminal
interface.  This allows one to execute any programming instruction on
the target device, whether or not avrprog supports it explicitly or
not.  Thus, one can use this feature to program fuse / lock bits, or
access any other feature of a current or future device that avrprog
does not know how to do.

Add in comments, an experimental instruction format in the
configuration file.  If this works out, it would allow supporting new
parts and non-orthoganal instructions across existing parts without
making avrprog code changes.

Brian S. Dean 26223415e6 Add a -V option to display the version information about each
component module.  This is intended for support purposes, so that I
can tell unambiguously what version a binary out in the field is.

Additionally, display a revision timestamp along with the version
number.  This also is intended for aiding in support and is the Unix
time of the latest component module.  Having this, should allow me to
do a "cvs co -D timestamp avrprog" and get exactly the source of the
version that is being reported.

fileio.c: Properly handle all the Intel Hex record types that I can
          find information about.

Brian S. Dean eff6750e5c Move pin definitions to their own file.
First pass at providing feedback via the optionally connected leds.  I
don't actually have any of these attached to my programmer, so I can
only guess as whether this is toggling them on and off correctly.

Also, enable and disable the optional 74367 buffer.

Brian S. Dean fc56e6b4f9 Rearrange the pinout for the programmer to be a little more logical.
Provide hooks to support a buffered programmer, pin 6 is now used to
enable a buffer that can be used to isolate the target system from the
parallel port pins.  This is important when programming the target
in-system.

Totally change the way the pin definitions are defined.  Actually
set/clear pins based on the way more intuitive pin number, instead of
PPI data register, bit number combination.  A table of pin data is
used so that any hardware inversion done by the parallel port is
accounted for, what you set is actually what appears at the pin.
Retain the old method for handling Vcc, however, because the hold
method is much easier to use when setting / retrieving multiple pins
simultaneously.

Brian S. Dean 209f979c7f Makefile : use gzip -f for man page installation so that we don't get
prompted.

avr.c avr.h fileio.c term.c :

     Change the avrpart data structure so that the typedef AVRMEM is
     used as an index into an array for the sizes of the memory types
     and also for pointers to buffers that represent the chip data for
     that memory type.  This removes a lot of conditional code of the
     form:

		switch (memtype) {
			case AVR_FLASH :
		 	...
		}

     Also, re-code avr_read_byte() and avr_write_byte() to properly
     handle the flash memory type without having to tell them whether
     they should program the high byte or the low byte - figure that
     out from the address itself.  For flash memory type, these
     routines now take the actual byte address instead of the word
     address.  This _greatly_ simplifies many otherwise simple
     operations, such a reading or writing a range of memory, by not
     having to worry about whether the address starts on an odd byte
     or an even byte.

Brian S. Dean c06319e33c Return error codes instead of exiting, thus making sure that we exit
only via main() so that the exitspecs are properly applied.

When reading input data from a file, remember how many bytes were read
and write and verify only that many bytes.

Don't complain when an input file size is smaller than the memory size
we are programming.  This is normal.

Brian S. Dean 4265bfa150 The program was getting too large for a single file. Split it up into
more modular pieces.

Also, accept command abbreviations as long as they are not ambiguous.
