Hey all,
first of all I really appreciate all the work this community is doing to
get allwinner hardware working with linux.
My hardware is a ClockworkPi Devterm R01:
https://www.clockworkpi.com/product-page/devterm-kit-r01. The "official"
linux is a 5.4 linux distro which is a slightly modified version of the
official allwinner linux sources for that
device: https://github.com/ardera/clockworkpi-r01-linux (linking my repo
since it has the git history restored)
I'd like to boot Samuel Hollands linux fork on it, since the hardware seems
to be very close to the Nezha board. So I just built his fork
(`riscv/d1-wip` branch, with `nezha_defconfig`) and replaced the kernel on
the official image with my custom-built kernel.
However, when booting, i get kernel panic pretty early on in the boot (see
attachment).
I'm not that experienced with hw bringup so I'm a bit lost here. Is that
just the kernel equivalent of a segfault? Could that mean something with
the device tree is wrong? Could it be caused by an incompatible u-boot?
