No response to cm commands, such cm info and cm radio

I am doing power on/off tests.
After many times of power on/off, sometimes there is no response to cm commands, such cm info. “WP76xx Firmware Release 10” is used on my board.

Anyone can help me with this?
Thanks.

Is Legato running when you try to execute the cm commands?
My guess is that Legato has not booted properly (rollback possibly?) and Legato is not running when you try to execute those commands.
It is something that I and other users have seen before.

Thanks for this info!
I will check it when encountering this problem next time.
