Hello TI Experts.
We are using the TDA4AL platform, version sdk0806.
We are currently doing power-on and power-off stress testing. In the tens of thousands of tests on multiple boards, we found that some boards have the following errors with probability. idc_iuni.bin is an application we developed. Sometimes it is printed that it is caused by other applications, such as idc_vial.bin. Temporarily infer that it has nothing to do with our own application, because the entire kernel is dead, and it seems that it is not caused by the upper-level process. So I would like to ask what exactly causes such problems and how to solve them.
