Hi

I am assuming you are using a DK as you are running the RTT. How is your circuit connected, could it be possible that the programming chip isn't getting a high enough current to run while your motor is running? Please specify what kind of "motor" this is, what SDK you are using, and confirm whether or not you are using a DK.

Best regards,

Simon

Hi Simonr

Sorry for my unclear description

1. I use a custom board

2. The motor is used to move up and down , sometimes when motor moves ， then the RTT stop working (but other fuction like ble works well)

3. SDK‘version  is 12.3

I guess the reason is power noise,

But MCU have not reset when the motor moves，only RTT stop working ，this phenomenon confused me
