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

Hi. The same thing is happening to me as well. As soon as I start the soft device, run the following code

sd_mbr_command_t com= {SD_MBR_COMMAND_INIT_SD,}; sd_mbr_command(&com)

the code execution will stall. When I break the code manually the instruction pointer seems to be pointing to 0x14fde. I ran the exact same code on two computers and on one the code runs fine but the other it is stalling. The only difference between the two computers is the version of IAR ide that is used to compile the code. The one that works is running on version 7.20.2.7431 but the one that fails on 7.40.2.8570. I am using the same SDK and SD as Sam Wagner
