We meet three unexpected error and reboot. They are (1)!!! bus error, (2)!!! Alignment error, (3)Unclaimed Interrupt
And our environment is introduced in https://community.nxp.com/message/1185211
1.!!! Bus error
Our Coord connect with host via Uart1, and pass Zigbee Packet between host and child. The largest number of wireless packet can up to 30 packets per second. Sometimes, average 12hour, Coord meet Bus error and reboot.
I dump the content of Stack, and use addr2line. I find the top of Stack is point to some Func(Always the 2nd address value). Can I confirm the question occured when running these Func?
I guess it mat be caused by RF conflict with Uart. How can I confirm? Or other possible reason?
2.!!! Alignment error
It is appeared under the same circumstance with the above question. But this problem we meet about 2 day per occuring. How can I find reason of this problem?
Stack content of this question shows the function being SDK Func, not application Func. Can I thin this problem caused by SDK?
When I init chip, I don't init other peripheral except we using. When this problem appears, How can I confirm which peripheral is interrupted?
I guess I can register every peripheral ISR in PIC_SwVectTable. When some peripheral interrupted, I can find which peripheral. Does it work?
