Other Parts Discussed in Thread: DRA829
Hi,
We had developed a controller module with TI processor DRA829 and now it's in mass production. Recently, one board is reported failure on customer KEY programming. We tried to do OTP flashing manually, found it failed on the first step (totally nine images for the OTP flashing). The error message is shown below.
The MCU UART print out of the board (when it is powered on) is shown below,
We had already produced several batches, but this is the first time we meet the problem.
Please comment what could be the cause and any suggestion to that.
Thanks,
Qiang
