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?

Can you give me some more logs or context on when this happens or when the error is returned? What was the state of your application then? What kind of tasks your application have? 

Are you using any of the peripherals without using our drivers from the SDK? 

There seems to be a hardfault from the softdevice, but hard to say why it happened without getting more context of the call stack when this error happened.

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?

[dogFight2022]

yes,we will continue debug this problem,collect more info for the problem.it happened very little,but will hanpp.i will offer more context for next occurs.is there some good ways for collecting infos on the problem?

[dogFight2022]
