Hello,
I am using TDA4 on my desk and also in the system, but it is not working reliable in both places.
Case 1) When board is working, I am using SSH or UART or nothing, after some time it falls into hard fault, without dependencies on the load of the processor. Power reset is necessary to reborn the board. SSH and UART connection becomes unreachable (UART just not respond) after this error. I attached two fault reports which I receive by UART before the fault. Also the board seemed working, processor stay be heated.

Case 2) I'm receiving and sending a lot of UDP packets in TDA4. For example I have a stream from the camera there. After some error (which is not recognizable through Ethernet port) TDA4 stops communication. When we decrease the number of sent UDP packets, problem disappeared, but this solution is not applicable for us.
Maybe you already met this issue and have any solution.
Maybe boot log can be also useful.
