[PATCH] Refactor spi_read_status_register usage
by Carl-Daniel Hailfinger 08 Mar '14

08 Mar '14

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 28 Feb '14

28 Feb '14

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)?

Getting Flashrom running on OS X v10.9.2 (Mavericks)

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? Also, DirectHW needs to be installed, and when attempting to install that (using the cd, and then make command), I get the following ** BUILD FAILED ** The following build commands failed: CompileC build/DirectHW.build/Release/KEXT.build/Objects-normal/i386/DirectHW.o DirectHW.cpp normal i386 c++ com.apple.compilers.llvm.clang.1_0.compiler (1 failure) make: *** [build] Error 65 192:DirectHW ouimetnick$ Could anyone offer some help? I want to get Flashrom running so I can use my Bus Pirate. Thanks, Nick ouimetnick(a)gmail.com

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

flashrom support for SST26VF064B

Hi flashrom folks, I'm trying to add support for SST26VF064B after I got a patch from Elias. I made some changes to it after reading the datasheet, but none of the block erasing commands worked, and I don't know why... Erasing and writing flash chip... *Trying erase function 0... 0x000000-0x000fff*:E program_opcodes: preop=5006 optype=463b opmenu=05200302c79f0190 on-the-fly *OPCODE (0x20)* re-programmed, op-pos=2 FAILED at 0x00000010!

laptop bios
by Sheri Soltz 26 Feb '14

26 Feb '14

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...

This chip may contain one-time programmable memory. flashrom cannot read and may never be able to write it, hence it may not be able to completely clone the contents of this chip (see man page for details). 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
