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 > > Thanks > -- > Hoang Tung (Mr) > > > > > _______________________________________________ > flashrom mailing list > [email protected] > http://www.flashrom.org/mailman/listinfo/flashrom _______________________________________________ flashrom mailing list [email protected] http://www.flashrom.org/mailman/listinfo/flashrom
