UART handler mode issue
We are developing some applications based on the DSPS sample code. The firmware is loaded onto the DA14580 chip from an external M4 processor via UART. A few seconds later after the Dialog chip boots successfully, the M4 processor send some message through the UART, the DA14580 M0 processor immediately enters into the Handler Mode around address 0x00028158. The debugger cannot display what c code is running. It is running some instructions from Disassembly (see below). Is there anyway to figure out what is the code doing and why the processor enters into this handler mode? Thanks.
