@Caldarie - when I follow the blog and use:
make ARCH=arm64 O=kernel_build tegra_defconfig
I get an error about drivers/net/ethernet/nvidia/Kconfig:30: can't open file "drivers/net/ethernet/nvidia/eqos/Kconfig". It seems it is an old problem (R32.1 TX2 how can I build extra module in the tegra device - #9 by linuxdev) - are you sure you did everything in order and it worked?
I can fix it by using /usr/src instead of /home for the kernel source like in that post, but then I cannot compile make defconfig-iwlwifi-public and it says I don’t have the kernel headers installed.
Also the a) Go to drivers/bluetooth/ and open ‘btusb.c’ to manually add: part is wrong no? You must add it, but not where your example shows. The example seems to be from the blacklist where it already exists - shouldn’t it be removed from it as well?
Also, if I don’t need bluetooth but only wifi I still need to do this right? On Jetpack4.3 the wifi module didn’t seem to be working out of the box so I assumed that I had to recompile the modules.
