Now press Ctrl + C to drop into the U-Boot shell. Enjoy! :-)

oreboot DRAM init
|
||||
|
||||
NOTE: I reverse engineered the DRAM training blob and translated the other DRAM init code from U-Boot, staged at https://github.com/orangecms/oreboot/tree/all-the-things-wip/src/mainboard/spacemit/k1x/bt0
|
||||
|
||||
NOTE: In order to get the binary with the necessary header, I hacked a bit into the vendor tool, created a custom JSON config for it (see below), and fixed some bits in U-Boot. See https://github.com/orangecms/spacemit-u-boot/tree/v2022.10-k1 - it's a bit messy. I could flash the eMMC with that U-Boot, but then got authentication (header verfiication) errors when booting. No clue why. So just use the tool to create the binary; ./tools/build_binary_file.py -c oreboot.json -o oreboot.bin.
|
||||
|
||||
Will see if we can port the tool to create the header to make it easier to use.
