Compatibility with ECS Socket AM2+
by Leif Middelschulte 03 May '14

Hi, firstofall thanks for your effort with flashrom. It’s really great to be able to flash a bios image independently of Windows. Sorry I didn’t catch the entire/verbose output. Nevertheless I could successfully flash a vendor bios for the following Motherboard: http://www.ecs.com.tw/ECSWebSite/Product/Product_Detail.aspx?DetailID=865&M… Regards, Leif

Is there a sure-fire way to reset any BIOS flash image to its default, out-of-the-box state with no special equipment?

Hi, I am seeking an answer to an apparently obscure question. If I install coreboot on my BIOS (UEFI motherboard) and the computer fails to boot, can I reset the BIOS flash to its default image? I've read about possibly changing jumper positions or removing the BIOS battery, but I can't seem to establish if these are sure-fire ways of restoring the original BIOS flash image. I'd like to attempt to install coreboot on a motherboard that doesn't appear to be coreboot-supported, but only if I know I can completely undo this. Is the default BIOS flash image preserved somewhere on a ROM chip or can it only be restored with special equipment? I definitely do not want to end up with an unusable machine. Thanks! Jim

I have added your board to our list of supported hardware and will commit that later together with other small changes. Please don't send firmware images to the list in the future. They are copyrighted... Also you might be interesting in the -o switch that creates a verbose log file (as alternative to redirecting stdout and stderr with > stuff). -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

raspberry pi as lpc programmer
by goran metlic 03 May '14

03 May '14

Hi I'm not proficient in programming and have used before available information about flashing bios chips. I have flashed SPI bios using flashrom and RPI. Now I need to flash LPC chip - SST49LF080A. I don't have access to programmer that can program this chip but i was wandering what needs to be done to enable raspberry pi to flash this type of chips. I have seen programmer using Atmel chip so i wanted to know if something can be changed on raspberry pi side to enable LPC flashing (or parallel for that matter). I'm willing to experiment with raspberry pi and LPC / parallel chips. Kind Regards Goran Metlic

Flashrom very slow to erase chip
by anthony enos 03 May '14

03 May '14

I am using Dediprog programmer and currently using 8192 kB SPI Winbond "W25Q64.W" chip. Currently my time to erase chip is in excess of 10 mins. On the programmer i can see it is working in 4 KB chunks at about 4 chunks per second. So very roughly 16 KB/s. Is this right? Is there any way to erase a chip faster. Any insight on this matter would be greatly appreciated. Regards, Anthony Enos
