[PATCH]buspiratespi on mingw
by Patrick Georgi 06 Jan '10

06 Jan '10

Hi, attached patch makes the buspiratespi programmer compile and run on mingw. Build tested on linux, too. Tested without any device attached to the buspirate, which gave me much text (with -V) ending in: Found chip "Generic unknown SPI chip (REMS)" (0 KB, SPI) at physical address 0x0. === This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITE Please email a report to flashrom(a)flashrom.org if any of the above operations work correctly for you with this flash part. Please include the flashrom output with the additional -V option for all operations you tested (-V, -rV, -wV, -EV), and mention which mainboard or programmer you tested. Thanks for your help! === No operations were specified. buspirate_sendrecv: write 1, read 5 Sending 0x00, receiving 0x42 0x42 0x49 0x4f 0x31 Raw bitbang mode version 1 buspirate_sendrecv: write 1, read 0 Sending 0x0f, receiving Bus Pirate shutdown completed.

[PATCH]various serial fixes
by Patrick Georgi 06 Jan '10

06 Jan '10

Hi, attached patch changes: - replace the hand written serial input flush routine with the termios one. - serialport_discard_read isn't necessary anymore - it just wrapped sp_flush_incoming with no extra value. - serialport_read and serialport_write would misbehave if read or write didn't process everything in one go. All untested as I don't have a system where these are used. Just wanted these issues out in public. Signed-off-by: Patrick Georgi <patrick.georgi(a)coresystems.de>

[PATCH] Fix FT2232-only compilation
by Carl-Daniel Hailfinger 06 Jan '10

06 Jan '10

Some programmers (most notably FT2232SPI) use fallback_* and noop_*, but those functions lived inside internal.c and were unavailable if no PCI-based programmers were compiled in. Move those functions to the new file programmer.c. Thanks to Patrick Georgi for finding this. In the future, we should move other stuff to programmer.c as well, especially programmer definitions and wrappers which now live in flashrom.c.

[RFC] JEDEC refactor w/ conversion notes and file eliminations
by Sean Nelson 04 Jan '10

04 Jan '10

This patch demonstrates how we could refactor the jedec code. After the refactor we can delete these: * am29f040b * en29f002a -> file_not_used * m29f002 * mx29f002 * pm29f002 * sst49lf040 * w49f002u These files can be deleted if we *could* find a way to integrate the problems into jedec.c: * w29ee011 -> checks specifically for w29ee011 * w39v040c -> checks for lock in probe: address 0xfff2 * pm49fl00x -> uses chip protect code * m29f002 -> block based writing * m29f400bt -> block based writing I was looking through these two files and saw that they used variable block sizes for writing sectors, maybe we can do something simpler to block_erasers: * m29f002 * m29f400bt There are a few files that performs another map_flash_registers() after successful probe, I was wondering if we could add the re-mapping to probe_jedec_common or if its safe to omit the function call: * pm49fl00x * stm50flw0x0x * w39v080fa List of chips that use a specific addressing for command codes: 0x2AA based chips: * am29f040b * mx29f002 * pm29f002 0xAAA based chips: * m29f002 * m29f400bt 0x2AAA based chips: * pm49fl00x * sst49lf040 * stm50flw0x0x * w29ee011 * w39v040c * w39v080fa * w49f002u If you want I can send my full notes so you can see what each file's functions can be converted to, on request. I don't know if my methods for the address mask is proper. If you can think of a better way, I'm all ears. Yes, I did work on this all Christmas Eve.

Author: snelson Date: 2010-01-04 18:15:23 +0100 (Mon, 04 Jan 2010) New Revision: 828 Modified: trunk/chipdrivers.h trunk/flash.h trunk/flashchips.c trunk/jedec.c trunk/pm49fl00x.c trunk/sst49lf040.c trunk/sst_fwhub.c trunk/w39v040c.c trunk/w39v080fa.c trunk/w49f002u.c Log: The patch converts jedec functions into mask-based generics which can be used for many chip provided the only changes are the addresses are converted from 0x5555/0x2AAA to 0x555/0x2AA or similar. The patch mostly changes jedec.c, but a few other files are changed because they use the jedec functions within their own functions. The patch also adds a copyright line to flashchips.c because of my recent work in converting AMD and Atmel chips to use struct erase_block.
