Hi
Customer met an exception, wanted to analyze the stack content, but cannot find the document for the RISC core of JN5169 ， so do not know the sequence to push core registers.
who can help to provide the sequence to push register for exception processing? Customer wants to find the document to describe this.
Thanks!
Derek
@hiwave can you let us know the customer name related to this case?
@amigo_li can you help here?
Hi @hiwave
If customer enable debug log and when device crashed, it would print message like below:
APP Start: Switch Power Up
APP Start: Watchdog timer has reset device!EPCR = 9dcf2 : EEAR = 9dcf2
Stack dump:
4007fc4 : 00080fe2
4007fc8 : 0009cec0
4007fcc : 1bf887c9
4007fd0 : 000882c6
4007fd4 : 00088ef1
4007fd8 : 00088f37
4007fdc : 00085df7
4007fe0 : 00084940
4007fe4 : 00080fe2
4007fe8 : 00001a12
4007fec : 00000000
4007ff0 : 00000000
4007ff4 : 0009cbfe
4007ff8 : 76543210
4007ffc : fedcba98
Then we can use tool : arm-none-eabi-addr2line -e app.elf 0x00088f37
You can check the source code in AN1189, the stack dump message would be print when there is a watchdog reset.
