Hello Experts
we use AWR2944BS chips in our vehicle radar, in order to meet customers' demands, we need to active these chips before programming by Xmodem protocal.
But with the mass production, we often come across a problem that the UART often record a errorcode 07 during the period of activation
I did an investigation about this errorcode, for the details as below:
Next is the sequences of DC POWER ON:
1. DC power supplied 12V for radar PCBA
2. delay 500ms
3. DC power supplied 1.7V for activation circuit (spec ±0.05V）
4. delay 1000ms
5. Datas transfer by Xmodem protocol
6. 1.7V power off
7. delay 1500ms
8. 12V power off
I also used the oscilloscope to probe for the 1.7V signal, for the details as below:
For the errorcode records, details as below:

I wonder if there are something wrong that caused this 07 issue in the sequences of DC POWER ON?
are these sequences of DC POWER ON correct? besides this, are there other potential factors causing this problem?
thanks
