Does anyone know how I could build flashrom statically? export CFLAGS=-static does not work. Thanks, Joshua McDowell - Lead integrator Sent from my Blackberry

[flashrom] Using 3c905B as programmer.
by Mats Erik Andersson 21 May '09

21 May '09

Hello there, let me point out that the recent code to use 3x905C as a flashrom programmer, will almost certainly fail for the predecessor 3c905B-TX (id 0x9055). The reason being that there is a bug where the mii unit interferes. Thus one needs to put the media subsystem into state 0x06, i.e. internal mii, by a write to register window no. 3. Then window no. 0 can be activated, any read or write of flash may follow, and upon completion the old media configuration should be restored. After much effort I found this out for my own class of kernel modules aimed at using network cards for in situ programming. Interested developers can glean the details off a utility "bromutil.c" contributed with the Etherboot or gPXE distribution. That code is not by me! Best regards Mats Erik Andersson

Re: [coreboot] Removal of older linuxbios to restore factory BIOS.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I had an issue in the past where I was trying to re-create the Linux Networx ebi image creating process. The etherboot developers were helpful in making me successful, but what we learned was that the 2.6 kernel changed some where ( not sure where ) and that etherboot did not like the said change. Again, I never nailed it down, because this only effects old versions of etherboot. I can build any kernel source tree I want, but then the question remains. Will flashrom work with a 2.4 kernel? If not, can a 2.4 kernel be booted, then a 2.6 kernel be booted from the 2.4 kernel. This is a question I also plan to ask the etherboot guys.

Hello, i tried flashrom on nForce2 based motherboard with phoenix bios, got following output. lspci -n in attachment # ./flashrom flashrom v0.9.0-r525 No coreboot table found. WARNING: No chipset found. Flash detection will most likely fail. Calibrating delay loop... OK. Found chip "SST SST49LF040" (512 KB) at physical address 0xfff80000. No operations were specified. -- Maciej Pijanka, PLD-Linux Developer, Reg Linux user #133161 POE/Perl user

Probably the first thing to do is to get it to boot into Linux. Have you asked for help from the etherboot developers? Thanks, Myles

It is currently unknown to me if flashrom supports this motherboard. Flashrom is what I planned to try and use, but I can't get etherboot to boot the same 2.6 kernel/initramfs combo package that I built. Even though a new node with a much newer version of etherboot boots the same .ebi image just fine. I think older versions of etherboot are broken with 2.6 kernels. The chips are soldered onto the mother board, they are not socketed. Which means they used "lbflash" to get linux bios on them to start with. I do have the factory bios image. I am currently trying to netboot the nodes, but they will not netboot, and I think that is related to brokenness in older etherboot. Thanks in advance.
