Hi Alec,
I opened this thread as the continuation of the E2E post below:
https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1052994/iwr1642-inquiry
Please see this last response from our customer:
"The serial port cannot be detected, and the NRST light is not on. Only the power light is on. Some time ago, the NRST light was on occasionally, and the serial port will be detected. In the last two days, the NRST light is not on, and only the power light is on"
I hope you can further help us. Thank you.
Kind regards,
Gerald
