Can't build driver on Pi4 64bit #54

Closed esteimle closed 2 years ago

esteimle commented 2 years ago

I'm trying to build the driver from here: /nrc7292_sw_pkg/package/host/src/nrc (I just checked out from git yesterday).

My kernel version is Linux raspberrypi4 5.15.67-v8+ #1584 SMP PREEMPT Mon Sep 12 13:06:37 BST 2022 aarch64 GNU/Linux

It gets pretty far but gets stuck when it can't find some functions such as _raw_spin_unlock. I see they get created in the nrc.mod.c during the build though. So far I haven't found much about this while searching other than another forum saying it might be an RPI4 kernel bug. Any idea what might cause this?
