    I tried debugging this by adding a debug line: 

    static int sysc_reset(struct sysc *ddata)
{
	int sysc_offset, sysc_val, error;
	u32 sysc_mask;

    dev_crit(ddata->dev, "!!!!!!!!!!!!!! RESET device: %s\n", dev_name(ddata->dev));

    The delay cause by printing at this level, seems to fix the issue, I can't trigger the Panic anymore with this enabled.

    After looking a bit further i see that the sysc_reset function support a delay that can be set from the devicetree in the target module. I.e.: ti,sysc-delay-us. But for this I need to know which target module is the culprit. Any ideas?

    Hi,

    What is the exact AM3354 part number do you use?

  • 0 in reply to Bin Liu

    Hi Bin Liu,

    Thanks for replying. I am not completely sure about the part number, but it is the SoC included in the Embedian Smarc am335xt 1GHZ. 

    http://www.embedian.com/index.php?main_page=smarc_t335x_download&products_id=1&zenid=48ijd32lsjo7anvv5ahi5tpgm0

    Also I have added an fsleep(5) as tmp workaround in the sysc_reset, everything behaves nicely. 

    Cheers,

    raymond.

    Hi Raymond,

    I probably know what causes the sysc_reset crash, but just need to know if you use ZCZ or ZCE package of AM335x. This was the part number question I asked.

    Ok check. I can’t seem to find it in the provided Embedian docs. I asked our electronics engineer, I will probably come back to you with an answer tomorrow. 

  • 0 in reply to justdev
    TI__Guru**** 175641 points

    If you have access to the AM335x device soldered on the board, you can see there is a print on its top surface, which is something like "AM335xxxxxx". This is the part number I am asking.

    Hi Raymond,

    This is not the AM335x device that I expect this sysc_reset crash to happen.

    justdev said:

    so I am not sure which target module triggers the crash, but let's start from USB. Please apply the following kernel patch to set the delay to USB module.

    Hi Bin Liu,

    I have made the changes, and I can't reproduce the issue anymore.
    Is this BUG fix done in an upstream Kernel source I can refer to in my patch?

    While I have your attention, I am also experiencing some other kernel log messages, that do not cause an issue. I would sleep better if you said not to worry about it, or if you said: do this to resolve it ...
