OpenCellular project provides very decent Coreboot instructions. In particular, they suggest that you flash just the coreboot section of ROM as per https://github.com/Telecominfraproject/OpenCellular/wiki/How-to-coreboot#updates
===================== Updates can simply applied by using the coreboot flashrom tool and applying this patch. Update FW partition A flashrom --fmap -i RW_SECTION_A -w coreboot.rom Update FW partition B flashrom --fmap -i RW_SECTION_B -w coreboot.rom ===================== If you do this, you won't need the descriptor as you are not overwriting the entire ROM ________________________________________ From: [email protected] <[email protected]> Sent: Monday, May 6, 2019 11:38 PM To: [email protected] Subject: [coreboot] Building Coreboot Image for Opencellular Hello, I'm Karthik working on Opencellular (https://code.fb.com/connectivity/introducing-opencellular-an-open-source-wireless-access-platform/). I'm trying to build coreboot image for Opencellular Board. Finally, succeeded in building the image but with a WARNING message ** WARNING ** coreboot will be built without an Intel Firmware Descriptor. Never write a complete coreboot.rom without an IFD to your board's flash chip! You can use flashrom's IFD or layout parameters to flash only to the BIOS region. So my question is 1. Is it okay to flash the image with above WARNING message onto the board? Help me to find a way. Thank you, in advance. _______________________________________________ coreboot mailing list -- [email protected] To unsubscribe send an email to [email protected] _______________________________________________ coreboot mailing list -- [email protected] To unsubscribe send an email to [email protected]
