Since the aml-s805-cc works well using EFI, and now the capsule updates backend has been merged, let's enable the missing configs and add the required structures to support it. The GUID is dynamically generated for the board, to get it: => efidebug capsule esrt ======================================== ESRT: fw_resource_count=1 ESRT: fw_resource_count_max=1 ESRT: fw_resource_version=1 [entry 0]============================== ESRT: fw_class=B8079027-9B2C-57D4-86AA-CC782ADA598C ESRT: fw_type=unknown ESRT: fw_version=0 ESRT: lowest_supported_fw_version=0 ESRT: capsule_flags=0 ESRT: last_attempt_version=0 ESRT: last_attempt_status=success ======================================== On the host (with the aml_encrypt_gxl result binary): $ eficapsule --guid B8079027-9B2C-57D4-86AA-CC782ADA598C -i 1 u-boot.bin u-boot.cap On the board (from USB disk containing u-boot.cap at root): => load usb 0:1 $kernel_addr_r u-boot.cap => efidebug capsule update $kernel_addr_r The binary will then be flashed on the SPI.
