Hello Alex, bootefi hello fails since 5be444d14b380b210b246aa73dd5a111e4b1f80d efi_loader: consistent build flags for EFI applications
The problem is caused by incorrect entry point information in the EFI binary: Actual positions in EFI file: 0x178 hw_memcmp.constprop.0 0x1a8 efi_main Header information in EFI file (using https://github.com/xypron/efi_analyzer): BaseOfCode=0x148 AddressOfEntryPoint=0x148 So AddressOfEntryPoint is not pointing to efi_main().
