AM3358: reset distinguish and log

Xingyu Zhu
Expert 4315 points
Part Number: AM3358

Tool/software:

Hi expert,

Please help confirm whether the AM3358 has the following capabilities:
Customer is designing with the AM3358 and need it to distinguish between a power-on/cold reset and a warm reset. Additionally, we need to log the number of warm resets. If the warm reset count exceeds three, the system should stop resetting. Can the AM3358 itself implement this functionality? Thanks

Best Regards,

Xingyu Zhu

    The PRM_RSTST register (address 0x44e00f08) will tell the reset cause.

    How the warm reset will be triggered on your system? The AM3358 SoC itself doesn't count warm reset times. Your requirement has to be implemented in software depending on how the warm reset is triggered.
