Internal reset sources are listed in section 4.5.3 in the AM35x TRM Rev. C. This was already posted here: e2e.ti.com/.../865857
Hi Biser,
Thanks for the reply. We would like to know how to further identify the reset source that cause the 'sys_nreswarm' get low.
We use external CPLD to monitor and record the 'sys_nreswarm' get low event, and our software application only checks the event at the start point by reading the external CPLD. So when our application detects the get low event, it means the software has already been reset and re-executed(Of course, it is possible that the CPU is also reset and cause the software is re-executed). My concern is that how can software backtrack the reset source happened in last execution.
