gdb signal SIGTRAP 0x00014fde

[sam wagner]

Hi,

I am trying to bring up custom board with 51822 CFAC-A0. And I am continuously getting the following error as soon as the code does advertising_start(). I am using SDK7.2.0 and SD 7.1.0.

The address 0x00014fde appears to be from BLE stack. Please let me know what this issue could be...

Thanks, Sam

Did you include the -g3 flag in the makefile? Did you run 'mon reset' after load? If you post your .out file I can try it in the debugger here.

Somehow the issue went away and I am not sure why... One thing we fixed was the clock frequency setting since we are using 32MHz crystal on the board and that seems to have fixed several issues.
