How to read/write register on MT7621


I read somewhere on the internet about the reg tool that can read/write the register value of MT7621, but I could not find the command on my device.

How to enable it? or which way/tool to read/write the chipset register?


Enable /dev/mem interface and devmem busybox applet and you can read/write what you want if its memory mapped
