Hi NY,

What OS is running on AM3352, which version?

Please provide the relevant console log.

Hi NY,

Thanks for sharing the console log offline. I see the following message in the log:

Default Interrupt Handler: Unregistered interrupt occurred

But I am unable to locate this message in the Linux kernel source code, so I don't think this message was printed from kernel. Again, what OS is running on AM3352, which version?

Hi Liu, thank you so much for your checking. for your question about OS, they are not using OS, so it's bare metal.

Hi NY,

I am routing your query to out Bate Metal expert for comments.

Hi NY,

According to AM335x TRM, interrupt number 127 is reserved and you shouldn't receive this interrupt. I would recommend your customer to narrow down the problem and find out which component in their system caused this log: "Default Interrupt Handler: Unregistered interrupt occurred". They can start with no interrupts configured and add interrupt one by one until this log appeared.
