J721S2XSOMXEVM: ssh Connection drops after processgraph call

Varadharaj Ellappan

Hi Experts,

We are facing a crashing issue with the sample applcation with our target hardware based on J721S2 (Mideco platform) and QNX RTOS (SDP7.1). The same sample application is running without an issue on EVM. We use SDK 11.1 .

we face ssh link down issue o nthe target. Could you help us to resolve this issue as we need to run multiple TIDL nodes because of this ssh down issue , we cannot run our network continuosuly.

Thanks

Hi Varadharaj,

But is the board still running fine? Can you please on the Linux prompt? The error says that network connection error, which means it is not able to connect to the board, there can be multiple reasons for this error.

We are running on a QNX environment and suspect that loading the model onto the C7x DSP is causing the crash. Internally, the C7x core appears to go down, which then triggers the watchdog and results in a network disconnect. We also observed that when the crash occurs, IPC communication starts failing.

Is it possible that the C7x is causing this issue? We would appreciate your help in confirming whether a C7x crash or hang could lead to these symptoms.

Difficult to say just from the image, can you provide crash log from C7x?
