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 )
Starting grub2 as a payload might or might not work, can you troubleshoot your machine (= look at coreboot/the payload's console output) when it doesn't work as expected? Why did you choose grub2 over seabios?
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 ?
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
