Just attach an adapter and program away. Analyzing the the SPI bus will be the same. The only tricky part is having to snip or lift the CE# on a soldered down (vs socketed) FLASH device, to allow for FLASH emulation. Socketed Flash devices will be pulled and be replaced with an adapter that is pressed into the socket. The Xilinx Spartan -3e dev. boards are in. I'll post all the programming info up in the next few weeks. Someone has already done a multichannel Logic Analyzer design and written a JAVA Client for viewing data that should just about drop into the board. -Bari

[LinuxBIOS] [PATCH] flashrom: board specific enables based on matching pci-ids.
by Luc Verhaegen April 2, 2007

April 2, 2007

Hi, This patch adds initial flashrom support for matching mainboards based on pci-ids and pci subsystem/card ids. I've been using subsystem/card ids as part of my unichrome driver for years (xf86-video-unichrome/src/via_id.c). It is a very easy and painless system for identifying boards. It is relatively reliable, as it's always the same vendors that bugger them up (like VIA and ECS). Most vendors do play nice. But, in order to not mess up on devices like the EPIA-M, 2 sets of ids can be provided here. This gives pretty absolute reliability. Boards that don't need 2 matches can just null the second set. This code works correctly on: * EPIA-M with original BIOS. Matched and enabled correctly: $ Found "VIA EPIA M/MII/...": Enabling flash write... OK. * EPIA-M with linuxbios: not matched - pci subsystem ids not set correctly (yet!) - but not a problem as linuxbios never disabled write in the first place. * Asus A7V400-MX now works correctly (the CrashFree BIOS). This involves poking the Winbond LPC superio: $ Found "Asus A7V8-MX SE": Enabling flash write... OK. (This different name is correct. The difference is the northbridge revision and a sticker over "A7V8-MX SE") * Mitac 8999 laptop. Here GPIO15 enables the panel backlight, while on EPIA-M it enables rom write. Hence this being highly incorrect here. Requires nothing board specific and can flash np. * Shuttle SK43G requires nothing board specific. There is one more VT823x based device in this house that might get tested, and possibly implemented, this weekend. The Island Aruma support is currently kept as is. When no match has been made, or an error occured, then the name based matching is still attempted. I'm not a big fan of doing board specific things on the name alone. A user also shouldn't be allowed to specify a board name as that would lead to very randomly poking bits with potentially not-so-fun consequences. Testing here should imho involve editing flash_enable.c directly. Island aruma code can be converted with little effort, all it takes is the output of lspci -vn. Commit message, signed-off, etc are done git-style. Luc Verhaegen.

Re: [LinuxBIOS] reliable boot loader
by Capt Beany March 31, 2007

March 31, 2007

Many thanks for the responses and sorry for breaking the chain but im away from my usual PC and need to use a web account. Peter, The "threat" im looking to prevent is power loss / brain fade during an upgrade rather than deliberate corruption or bit failure of the boot medium. If power is lost during an upgrade, the boot loader would skip the newest (possibly truncated) kernel and boot an older one from (potentially) a different disk and would give me a working system to fix the issue remotely rather than a trip to a remote site. Uwe, I had previously looked at the fallback features of grub but there appears to be no way to get the system to boot in the case of a corrupted menu.lst file (ok so im paranoid :-) Joe, I hadnt looked at the nuni loader so thats another one to add to the list of projects to look into. I agree that this may not be directly relevant to LinuxBIOS but my interest was tweeked by the range of devices / filesystems that filo supports and I have no wish to reinvent any filesystem related wheels. Again many thanks for all your suggestions ___________________________________________________________ Inbox full of unwanted email? Get leading protection and 1GB storage with All New Yahoo!
