You’re right — CONFIG_REMOTEPROC_CDEV=y is in the current 6.12.x-ti kernels. Looking back at my notes I only hit it because we originally had r33, so it was off on my as-flashed image — apt install of a newer kernel fixes it, no rebuild. That was the only kernel config I needed. The only other kernel-side thing was a device-tree workaround for an SA2UL crypto-driver regression on r64 (it was oopsing the kernel / killing wifi at boot), not a config change. Claude helped me diagnose and proposes the fix, adding this to my custom device tree:
&main_crypto {
status = “disabled”;
};
I made a post about that a few days ago: kernel 6.12.57-ti-arm64-r64: sa2ul crypto driver oopses on iwd
Thanks Robert!
