joerg_wunsch ab52c9e972 bug #28744: Can't load bootloader to xmega128a1 (part 1, fix for
firmware < V7.x)
* jtagmkII.c: When going to write to the boot section of flash,
use MTYPE_BOOT_FLASH rather than MTYPE_FLASH
* jtagmkII_private.h: add MTYPE_BOOT_FLASH constant

joerg_wunsch 0d502e5e40 Shesh. The previous commit was a little premature. Drag the
"GO" code in again, but only activate it when programming an
Xmega device through PDI.

Wonderfully consistent tools.

joerg_wunsch 33a7e91b0e * jtagmkII.c (jtagmkII_close): The GO command before signing off
turned out to do more harm than good; on the Xmega, it caused exactly
the opposite reaction, the CPU stopped.  Even without it, after the
RESET command, the target is running already.  So, drop the GO.

rliebscher 751b96182c Parser does not need to know all programmer types now, new programmers
will update only the table in pgm_type.c.
  * config_gram.y, lexer.l: removed programmer type keywords,
    use now locate_programmer_type() function
  * pgm_type.[ch]: added new files for table of programmer types
  * main.c: allow list of programmer types by -c ?type
  * avrdude.conf.in: changed all type keywords to quoted strings
  * doc/avrdude.texi: changed description of type definition, list
    of valid types is now included from generated file
  * doc/Makefile.am: generate list of programmer types for doc
  * all programmers [hc]: add xxx_desc string for description of programmer

joerg_wunsch 95a42e16d5 Mega-commit to bring in memory tagging.
Each memory image byte is now tagged as it's being read from a file.
Only bytes read from a file will be written or verified (modulo page
granularity requirements).

* jtagII.c (jtagmkII_getsync): Instead of exit()ing from
deep within the tree when detecting the "need debugWIRE"
situation, properly pass this up as a return code.
* jtagII_private.h (JTAGII_GETSYNC_FAIL_GRACEFUL): New constant.
* stk500v2.c (stk500v2_jtagmkII_open): Don't tell anything

jtagmkII_getsync(); silently give up (all necessary has been
said already).

joerg_wunsch 358961e07e Bump timeout values to allow for slow clock speeds. Ideally, the
timeout should depend on the selected clock speed, but changing the
API for that would require quite some effort throughout the entire
code base.

joerg_wunsch 5279d55b9e After erasing an Xmega part, do *not* reinitialize the world, as a
subsequent programming operation will fail (for unknown reasons).
Actually, this was really only required for ancient AVRs, but doesn't
hurt on mega and tiny devices.

joerg_wunsch b827263faa Clean-up the Xmega erase functions.
* jtagmkII_private.h: Add CMND_XMEGA_ERASE as well as
the various XMEGA_ERASE_* definitions (from updated
appnote AVR067)
* jtagmkII.c (jtagmkII_chip_erase): Correctly implement
Xmega chip erase based on CMND_XMEGA_ERASE.
* jtagmkII.c (jtagmkII_pre_write): Remove, this turned out
to be just a chip erase.
* jtagmkII.c (jtagmkII_program_disable): Don't try reading
"hfuse" for Xmega parts; they don't have it.
* main.c (main): Re-enable auto-erase.  It's been done
before (as "jtagmkII_pre_write") in jtagmkII_paged_write()
anyway.  Xmega boot and application flash areas should be
handled separately in the future, so auto_erase can only
affect the area just being programmed.

* jtagmkII.c (jtagmkII_reset32): "status possibly used uninitialized"

joerg_wunsch 31fa98b708 Make the code compile warning-free:
- declare a dummy "struct timezone" for some Win32 systems (MinGW)
- fix a few printf() argument types
- get rid off the prevailing "all filedescriptors are of type int"
  attitude

The last item required a large sweep across the code, in order to
replace all "int fd"s by "struct filedescriptor *fd"s, and pass
pointers (as we cannot pass a union directly).  In return, the
code is now supposed to be fully 64-bit safe, rather than relying
on a 64-bit pointer being converted to a (32-bit) int and back
to a pointer as we did previously.

joerg_wunsch 351f329ec8 Replace the fallback of avr_read_byte() and avr_write_byte() to
avr_read_byte_default() and avr_write_byte_default (resp.) by directly
calling the latter functions from within all programmers that don't
implement their own read_byte()/write_byte() methods.  In turn, make the
read_byte() and write_byte() methods mandatory, and the cmd() method
(direct ISP command) optional instead (it's effectively mandatory for
any programmer using avr_read_byte_default()/avr_write_byte_default()
though).  Remove all the pointless cmd() method stubs from those programmers
that don't need it.

Eliminate avr_read_byte() as it was now completely identical to
pgm->read_byte().

joerg_wunsch abe6b26950 When failing to start in ISP mode, try debugWire instead. This
requires the user to eventually restart AVRDUE from scratch then.

jtagmkII_reset() had to get a second parameter in order to record
the reset mode.

joerg_wunsch 0599a70fd1 In jtagmkII_paged_write(), default the pages size to 256 early enough
so the buffer will then be allocated correctly.
