linux doesnt boot

[LaneaLucy]

finally got it that far, that at least opensbi boots by mapping it to different address space so it would fit into the 8 MiB. But now linux dont load and i have no idea how to debug it... any suggestions?

Running it in a simulation can help figureing out where the CPU is going. For early boot issues it can help.

You may have an issue in your dts / missing linux drivers aswell

[LaneaLucy]

it looks like its a opensbi problem. now got a tang primer 20k and with opensbi from here, it boots into linux, but with self compiled version it doesn't boot into Linux

[LaneaLucy]

this is the opensbi output of the working one

I don't know how, but it works now with self compiled everything
