You certainly want to save the original rom content, maybe store it on another machine, or get a spare chip to program coreboot.rom to. If you prefer to use an external programmer for SPI chips I can recommend the buspirate: http://flashrom.org/Bus_Pirate and compatible soic8 clips, if the flash is soldered to the board, http://www.hmcelectronics.com/product/Pomona/5250 > > Thanks > -- > Hoang Tung (Mr) > > > > > _______________________________________________ > flashrom mailing list > flashrom(a)flashrom.org > http://www.flashrom.org/mailman/listinfo/flashrom

How to reflash ROM file for Persimmon board
by Tung Hoang 07 Aug '12

07 Aug '12

Hi all I has a Persimmon board and I installed Ubuntu OS on it. I build Coreboot with GRUB2 for my board ( output is new ROM file ) Now, I intent use flashrom tool to flash new ROM file for my board. But I'm not sure my new ROM file is work well or not. As i understand, I can backup original ROM file of Persimmon board and using flashrom tool to load new ROM file to my board ( flashrom is installed on Ubuntu OS run on Persimmon board ) My question is : If my new ROM file is not working, How to reflash original ROM file ( which i backup from Persimmon board ) ? Can we use flashrom or other tool ? Thanks -- Hoang Tung (Mr)

Hello Greg, as i briefly mentioned in my previous mail, locked regions are a bit tricky and flashrom can not deal with them (i.e. unlock them). We are working on understanding how to unlock them, but intel does not provide us any documentation so please do not expect a solution soon. Since the SMBIOS information indicates that your company is assembling the firmware itself, maybe you could arrange that the ME region is not locked? As far as we know this is not a problem in everyday operation or for an update with flashrom (contrary to the scaring intel documentation that tries to convince you from the opposite). -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
