Other Parts Discussed in Thread: AWR1843
Tool/software:
Hi,
I am working with the AWR1843 device. It was previously working fine with the same hardware setup, but now it is no longer responding. I want your assistance in diagnosing the issue.
Issue details
-
The board is connected to both the power supply and the USB port, the same as before.
-
The COM ports (as shown in Device Manager) are detected properly, so the USB interface seems fine.
-
I am sending the same configuration file/commands through my program, which used to work earlier, but now the board does not respond with any data.
-
I also tried using the TI Online Visualizer / mmWave Demo Visualizer to send the configuration, but the device does not get connected (despite the COM ports being visible).
-
Snapshots of the COM port detection and connection attempts are attached for reference.
Steps already tried
-
Verified power supply and USB connections.
-
Checked COM ports are correctly enumerated and assigned.
-
Tried both my own program and TI’s online configuration page.
-
Used the same configuration files that were previously working.
Request
Could you please help me identify the possible reasons why the AWR1843 is no longer responding?
-
Is there a way to check if the device has gone into a fault state or requires reflashing of firmware?
-
Could this be related to the SOP mode settings, firmware corruption, or hardware failure?
-
Are there diagnostic steps you recommend to confirm whether the device is still functioning properly?
