Tool/software:
Hi, TI expert!
I have a development environment for am6234, with our own evaluation board.
The software SDK version is PROCESSOR-SDK-LINUX-RT-AM62X-08.06.00.42.
Recently, we found that resetting our 4G module can cause the system to freeze.
Today, when I hung up and didn't plug in the 4G module, I was letting it run on its own and found that it was running dead.
The scheduler automatically crashed，as shown in the following log：
