Hi Jorge, You can try to play with VBOOT_ENABLE_CBFS_FALLBACK option to use the payload from RO region, but it is under review currently (not in the main tree). Please do not change CONFIG_AGESA_BINARY_PI_LOCATION. The value is fixed, because the AGESA is not relocatable code. It must be put at the given offset, otherwise processor initialization will fail. > > fallback/dsdt.aml 0x30ec0 raw 6656 none > (empty) 0x32940 null 2042712 none > <-------------- > AGESA 0x2254c0 raw 690436 none > (empty) 0x2cde40 null 1405592 none > <------------- > bootblock 0x425100 bootblock 944 none > > Regards, > > _______________________________________________ > coreboot mailing list -- coreboot@coreboot.org > To unsubscribe send an email to coreboot-le...@coreboot.org -- Michał Żygowski Firmware Engineer http://3mdeb.com | @3mdeb_com
