With my EFI bootloader development over the years I already have a firm hand on how the external-facing API looks like, but I have to say I haven't really read the parts of the spec that describe the driver and internal APIs, so to speak.

Pedro,

Knowing UEFI is a really good baseline. Tianocore is UEFI + edk2 Build System + UEFI Platform initialization Specification [1],

There is some training here: [2]

Some of us also sit on the spec committees so you can usually get good quality answers to questions on the mailing list.

[2] https://github.com/tianocore/tianocore.github.io/wiki/UEFI-EDKII-Learning-Dev

Thanks,

Andrew Fish

I'm also quite interested in this one because I've written a read/write ext2 driver before, so the concepts are kind-of fresh in my head.
