Hello TI Engineer:
We currently have a project on TDA4 using ti-processor-sdk-linux-j7-evm-07_02_00_07 version for A72 development, using CPSW driver, the application uses TCP to send video streams to the PC, after a period of time the kernel panics, in I saw the same problem on E2E. TI engineers replied that there is a patch that can be fixed, but they did not share this patch in the link. Where can I download this patch?
