I’ve been banging my head against this wall for a while now, since the release of 5.10-rc1.
It seems that mainline kernel 5.10 is no longer able to boot on the Odroids. I have tested the Odroid N2 and Odroid C4.
The noticable difference between 5.9 and 5.10, is the removal of TEXT_OFFSET, which we used to boot AMLogic boards, like the Odroids.
I’ve tried reverting the commit that removed it, but it didn’t help and is not a solution, but a temporary workaround if it did.
I also tried creating a uImage kernel to use, instead of Image, but that didn’t help either. We are also still using the legacy .uimg initramfs, since it has been required for a while.
I made an issue a while ago on the Odroid Uboot github but it has gotten no response yet.
I do think its a uboot issue in some way, since @spikerguy was able to boot 5.10-rc2 on his Vim3, which is using a mainline uboot provided by Khadas.
Hardkernel does not provide any mainline uboots, only the BSP uboots (2015.01) and we can’t build mainline uboot, since it requires x86_64 binary execution to do so.
@spikerguy did find a download page for some mainline uboots from LibreElec, but they didn’t boot the 5.10 kernel either.
In the issue I linked above, is a UART log, for people curious. There’s not really anything different than a regular 5.9 uboot log. It just stops at “Starting kernel…”
Does anyone have any ideas? Anything we can try that we haven’t tried yet?
