Flashrom stuck using 100% cpu while probing for a chip
by GatoLoko April 28, 2014

April 28, 2014

I've tried to run flashrom -V to see if it could identify the chip on my new board (AsRock M3A-GLAN), and it got stuck while probing for the first chip. I've tried commenting out that specific chip (AMIC A25L05PT) and then it gets stuck on the next one. Then commented out all AMIC chips, and it got stuck on the next one (the first ATMEL on the list) I've tried with an older flashrom (0.9.2-r1141). It skipped some AMD chips, then got stuck on AMIC again. Talked with "tlt" and "stefanct" on irc and they asked for a strace and a gdb backtrace. Strace produced no results. Gdb log is attached. "stefanct" tried and reproduced it on a machine with nicintel_spi, but warned it was with an unsupported nic: http://paste.flashrom.org/view.php?id=738 -- GatoLoko

[PATCH] Refactor spi_read_status_register usage
by Carl-Daniel Hailfinger March 8, 2014

March 8, 2014

spi_read_status_register() is used in open-coded loops everywhere just to check if SPI_SR_WIP bit cleared. The logic is missing a timeout detection, and we can save quite a lot of code by introducing a function which waits until SPI_SR_WIP is cleared or a timeout is reached. Untested. May explode. Unfinished. More functions need to be converted to the new style. Will change behaviour if the chip is too slow or hangs. Should prevent flashrom from hanging without any visible output.

FAILED: SST49LF004A/B
by Tim Sebastian Feb. 28, 2014

Feb. 28, 2014

Hello, I'm trying to use flashrom to write a new bios to my device. It successfully writes the beginning of the bios and then fails with the error: 0x040000-0x040fff:W writing sector at 0xb7ea0000 failed! And again with the second erase function : Trying erase function 1... 0x000000-0x00ffff:EW, 0x010000-0x01ffff:S, 0x020000-0x02ffff:S, 0x030000-0x03ffff:S, 0x040000-0x04ffff:W writing sector at 0xb7ea0000 failed! leaving the bios in an unstable state. Further experimentation shows that writing the bios fails on both erasing and writing any sector after 0x040000, which is exactly halfway through the bios (2Mb out of 4Mb). Reading from those areas works without a problem. The lock status for every block is reported as 00, full access. Full log is below. I took a look at the source code for flashrom in order to see if I could easily fix the problem. I created a minimal flashrom-like clone that works with my chip: #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #include <stdio.h> #include <sys/mman.h> #define D(bios, pos) *((volatile char*)bios + pos) void write_byte(void* bios, int pos, char value) { char tmp1, tmp2; int i = 0; int tries = 4; retry: D(bios, 0x5555) = 0xAA; D(bios, 0x2AAA) = 0x55; D(bios, 0x5555) = 0xA0; D(bios, pos) = value; tmp1 = D(bios, 0) & 0x40; while (i++ < 0xFFFFFFF) { tmp2 = D(bios, 0) & 0x40; if (tmp1 == tmp2) { break; } tmp1 = tmp2; } if (D(bios, pos) != value) { if (tries > 0) { tries--; goto retry; } printf("Error writing value\n"); } } void try_replace(void* bios, int pos) { printf("Pos = %x:\n", pos); printf("Old: %hhx\n", D(bios, pos)); write_byte(bios, pos, 0); printf("New: %hhx\n", D(bios, pos)); printf("\n"); } int main() { int fd = open("/dev/mem", O_RDWR); void *bios = mmap(NULL, 0x80000, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0xfff80000); char old; try_replace(bios, 0); try_replace(bios, 0x20000); try_replace(bios, 0x3ff00); try_replace(bios, 0x40000); try_replace(bios, 0x50000); try_replace(bios, 0x60000); try_replace(bios, 0x70000); munmap(bios, 0x80000); close(fd); return 0; } And it outputs: Pos = 0: Old: 25 New: 0 Pos = 20000: Old: 81 New: 0 Pos = 3ff00: Old: ff New: 0 Pos = 40000: Old: ff Error writing value New: ff Pos = 50000: Old: ff Error writing value New: ff Pos = 60000: Old: ff Error writing value New: ff Pos = 70000: Old: ff Error writing value New: ff *Note that running this script will write garbage to your bios. Make sure to keep an original backup nearby.* As you can see, the problem is easily reproducible. What can cause writing to fail on where the high bit of the address is set (0x40000-0x7ffff)?

Hi Flashrom community, I'm trying to install Flashrom 0.9.7 on OS X v10.9.2 and I download the source, and then use terminal commands cd make AND I get an error Checking for libpci headers... .test.c:3:10: fatal error: 'pci/pci.h' file not found #include <pci/pci.h> So I read that I need to install PCUtils, and again, using the cd and then make, I get an error 192:~ ouimetnick$ cd /Users/ouimetnick/Desktop/flashrom/pciutils-3.1.9 192:pciutils-3.1.9 ouimetnick$ make /Applications/Xcode.app/Contents/Developer/usr/bin/make -C lib all make[1]: *** No rule to make target `/System/Library/Frameworks/ApplicationServices.framework/Headers/ApplicationServices.h', needed by `DirectHW.o'. Stop. make: *** [lib/libpci.a] Error 2 192:pciutils-3.1.9 ouimetnick$ How do I fix and install this?

Re: [flashrom] flashrom support for SST26VF064B

I don't see obvious problems either, but I did not read the datasheet. Two things I would check: - is there a write protection pin or register bits that might silently block any modification requests? - is the opcode sequence including wren? (this is probably done automatically by the ichspi driver, but i cant remember the details) And you could test if hardware sequencing (or SFDP) works as a workaround (but I doubt SFDP would behave differently for the lower block sizes and some of them are obviously wrong in the SFDP table anyway (or you have found a bug)). A full verbose log could shed some more light on it too, but I doubt it. If we get this to work we would probably like to commit this patch. For this either of you must sign it off according to http://www.coreboot.org/Development_Guidelines#Sign-off_Procedure -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

laptop bios
by Sheri Soltz Feb. 26, 2014

Feb. 26, 2014

I am trying to use flashrom to make a bios backup file on my lenovo thinkpad x131e chromebook (intel celeron 1007u cpu). I have set developer-mode and have physically opened the laptop and set the write protect switch to the write enable position. I am using the command "sudo flashrom -p internal -r backup.bin -o backup.log" But when I check the md5sum for backup.bin it is different from each previous backup.bin. Shouldn't the md5sum of the backup stay the same, as long as the bios has not been changed? Here is the output from backup.log: flashrom v0.9.7-r1711 on Linux 3.8.11 (x86_64) flashrom was built with libpci 3.1.8, GCC 4.6.3, little endian Command line (7 args): flashrom -p internal -r bku1.bin -o bku1.log -V Calibrating delay loop...

Block protection is disabled. Reading flash... done. Restoring MMIO space at 0x7ff643ff18a0 Any help/advise/suggestions would be appreciated. My aim was to use flashrom (if possible) to flash some bios other than the chromebook bios. Thanks Sheri

[Ubuntu] Dediprog SF100 support with Winbond W25Q64FW
by Kurt Qiao Feb. 24, 2014

Feb. 24, 2014

hello there, hope anyone can help me out, i try to implement flashrom to support dediprog SF100 on my Ubuntu. config as below: OS: Ubuntu12.04 X64 Dediprog: SF100, fm ver: 5.5.0 SPI ROM: winbond W25Q64FW, id 0xef 6017 i download flashrom v0.9.7 from http://flashrom.org/Downloads, i noticed v0.9.8 would enable dediprog by default but couldn't download now. unzip the download file and cd flashrom-0.9.7 and make with below cmd: make CONFIG_DEDIPROG=yes sudo make install plugging my SF100, and use below cmd flashrom -p dediprog -V i can see the program detect my sf100 but fail to detect the SPI ROM. log as attached file. ---log---- Probing for Winbond W25Q64.V, 8192 kB: RDID byte 0 parity violation. probe_spi_rdid_generic: id1 0x53, id2 0x4631 ----log--- as the log shows, seems flashrom read SPI ROM id is 0x53, 0x4631, but actually my SPI ROM on board is winbond with id 0xef, 0x6017(i confirm this with windows dediprog). so i have no idea why flashrom detect wrong id, and the flashchips.h already have WINBOND_NEX_W25Q64_W 0x6017 support. any help would be appreciate, thanks very much!

[PATCH] Use read-only mappings for DMI tables everywhere.
by Stefan Tauner Feb. 20, 2014

Feb. 20, 2014

R/W mappings cause explosions sometimes. Signed-off-by: Stefan Tauner <stefan.tauner(a)student.tuwien.ac.at> --- Simply rename (and refine) physmap_round to physmap_ro_round because dmi is the only user anyway. The patch was tested on real hardware that had problems without it.
