Oh yes - though I would let you know. Was interested that you board seem to use arm secure boot. As hardware was interesting (arm64+mali gpu) I just bought myself an odroid-c2. Its booting method is the same via arm secure boot

Now whats interesting is if I boot with no SD/MMC card in I still get

$this->bbcode_second_pass_code('', 'GXBB:BL1:08dafd:0a8993;FEAT:EDFC318C;POC:3;RCY:0;EMMC:800;NAND:81;SD:800;USB:8;')

So the BL1 part of secure boot is happening with no flash. So don't know where it is saved, maybe direct on the CPU chip. In which case *have* to boot via ARM secure bot, and that looks like it means uboot needs to be signed. So it explains the odd uboot you where seeing.

I'm still on the ubuntu that came on the emmc, will switch to arch when I've learnt everything I can.

This is interesting:

https://github.com/u-boot/u-boot/tree/master/board/amlogic/odroid-c2

looks like the u-boot.gxbb file is some kind of franken bl30, bl301, bl31, bl33 image, e.g. it contains a whole lot of the arm secure boot mechanism, and needs encrypting, and its closed source.

For me interesting to see arm hardware tied down so much ...
