ARM64 – Odroid C2 U-Boot – Latest.. — 4 Comments

  1. This sounds like there will be (soonish) ODROID C2 mainline support in U-Boot, is that correct? “Initial Meson GXBaby device trees for Tronsmart Vega S95 (S905)” should land in 4.6 kernel.

    • There will be support in U-Boot, and the ‘mainline’ kernel, but the timing is always difficult to predict.. The U-boot patches are still very much in the review stage, and not yet in the development tree..
      The ‘mainline’ kernel support may not include all features, at first.. If I had to guess, I would think that Odroid C2 support would be in the 4.7 kernel, but these things always have a habit of slipping..


  2. I’ve been successful in booting the c2 into full u-boot with Ethernet & UART support under rc3 uboot with patches applied including the 2 above. The other patches in the set should also be applied so 4 in total.

    Still uses the original first stage loader to boot into rc3 but the new u-boot rc3 has to be packaged and encrypted correctly for the first stage to be able to load it. This can be done manually through the fip_create and aml_encrypt_gbx scripts and then creating an image using dd commands to package it up.

    Looks something like this in the end…
