Post Body

I decided to try to develop a Yocto BSP for a security camera NVR based on the Hisilicon hi3520dv200. I've been learning a ton, but have been pretty stuck on the kernel hanging at this line of calibrate_delay(). https://elixir.bootlin.com/linux/v6.2.10/source/init/calibrate.c#L197

I found the SDK for Linux 3.0.8 online (available here:https://github.com/rgmabs19357/Hi3520D_V100R001C01SPC022_osdrv), but I've been struggling to update it to the latest kernel. This is complicated by the fact that the SDK doesn't use DTS for the kernel. I'm not really sure how to debug this to be honest, and if anyone has any tips, I'd love to hear them. Thanks in advance!
