The extlinux.conf file will be parsed by U-Boot and the "append" line will be evaluated and expanded and used entirely as the bootargs passed to the kernel.

The problem here is that we'll have one set of changes for 32bit platforms, where I think extlinux.conf ends up being best as if you look at other distributions (ie Debian), they end up doing the not-EFI path. But on 64bit, everyone goes the EFI path. So I'm working through making an OE image that has a reasonable grub-efi path for us to boot up with. -- Tom ^ permalink raw reply [flat|nested] 5+ messages in thread
