errInfo->err_code == 0x715(1813)

[dogFight2022]

we use nRF52833,SDK:S140,17.2,sometims,the device goes into trouble and the error code is 0x715.

here is the call stack:

/port.c:128 0x00027482 PendSV_Handler

/port.c:128 0x00058296 xPortStartScheduler

/port_cmsis.c:246

i  can not find what is the value mean.

so could someone give us some advice fot this trouble?

we run device as a ble peripheral ，and it happened when we just left it running idle.some others ble devices is working for transfer data.

our application is used base on the demo ble-uart,we received data from others,and process data,and then control the IO,like SPI,UART,PWM

I cannot find any error codes that has 0x715 as its define in the softdevice.Are you sure that the error code and stack data is correct? Seems like a stack overflow with corrupt values. Can you help me reproduce this error?

hi,i got more infos,i print log like this:printf("  %s: %d\r\n", errInfo->p_file_name, errInfo->line_num);

and the output like this :KGJ`h���@h: 536871936

coult it be help?

That looks like garbage values which tells me that the stack frame after the hardfault is pointing to random frame. This happens mostly due to stack overflows/corruptions.

i compare servel times fault,the value always is 536871936(equal to 0x20000400),rellay strange,seems likes in softdevice ram regin?
