Problems with flashrom
by Benjamin Z. Gregorian 11 Aug '11

11 Aug '11

Hi Guys I run into trouble using flashrom. first I downloaded the ROM to flash then I downloaded flashrom and run the following command ---------- sudo flashrom ---------- Result: flashrom v0.9.1-r946 No coreboot table found. Found chipset "Intel ICH7/ICH7R", enabling flash write... OK. This chipset supports the following protocols: FWH. Calibrating delay loop... OK. Found chip "SST SST49LF004A/B" (512 KB, FWH) at physical address 0xfff80000. No operations were specified. --------- I assumed that flashrom can burn my BIOS (since there was no warning given) Then I tried --------- sudo flashrom -wv Desktop/Downloads/P5LD2-2002.ROM --------- Result was that two opperations are not permittet or so After studying the man page I ran the following command --------- sudo flashrom -w Desktop/Downloads/P5LD2-2002.ROM --------- and got panic!!!!!!! -------- flashrom v0.9.1-r946 No coreboot table found.

[PATCH] add support for AT49F040
by David Borg 10 Aug '11

10 Aug '11

Hi, I was adding support for the AT49F040 parallel flash chip, but have some questions. This chip has a boot block which once locked cannot be erased / rewritten. Should I add erase functions for both cases? Currently the erase function handles unlocked chips only. In addition, the datasheet specifies no command timings, is the timing something I can infer from the read / program cycle characteristics tables?

[PATCH] Move erase checks out of chip drivers
by Carl-Daniel Hailfinger 26 Jun '11

26 Jun '11

Erase functions are no longer called from chip drivers and thus their internal erase verification can be moved to generic code. This also makes it easier to skip the verify step if desired.

[PATCH] Use strlen for const strings
by Carl-Daniel Hailfinger 26 Jun '11

26 Jun '11

Replace sizeof("string")-1 with strlen("string") We want to avoid calls to strlen at runtime if the string is already known at compile time. Turns out that gcc and clang will recognize constant strings and compute the strlen result already at compile time, so trickery with sizeof only reduces readability but does not improve the code.

[PATCH] Flush stdout after each message
by Ed Swierk 19 Jun '11

Currently messages like "Writing flash chip..." that don't end with a newline are buffered until the operation is complete, unless the particular write function generates status output in the meantime. Flushing stdout after each message ensures that the message appears immediately.
