SDK_ERROR observed

Hi Team,

I'm developing a custom app, based on the ble_app_uart.

I'm observing a error : SDK_ERROR (NRF_FAULT_ID_SDK_ERROR).

I'm unable to root cause it and also unable to get any information about this error.

I even though got the error details connecting the debugger.

Can you please share some insight about this crash/error. It will help to debug further the issue.

I understand the 

Below are error details (taken from function app_error_save_and_stop()):-

  • Hi Vidar,

    Below are the details with SES v5.42a :-

    If I continue execution, it go to the address 0x781b330a and on every continue be there.

    Also, in the release notes, SES v4.50 is mentioned. Hence, I even tried with v4.50 and below are the details on crash:-

    And continuing the execution, below are register values (same as that of SES v5.42a

    Also, using the project saadc_pca10040e, works fine (on all SES versions).

    The above logs are for project ble_app_uart_pca10040e_s112.

    I even tried to place a breakpoint at the first instruction in Reset_Handler() at instruction "b nRFInitialize", even then the execution didnt stop at this first instruction and instead directly shows the instruction at address 0xA60.

    From few posts it looks like it could be related to the Flash Placement (note - I didn't change it), hence attaching the flash_placement.xml.

  • Hello,

    Please upload your project file too (*.emProject). From the images you posted I see that you have a corrupted/invalid stack pointer.

  • Hi Vidar,

    Uploading by project file.

    5153.ble_app_uart_pca10040e_s112.zip

    *Zipping it as it doesn't allow me to upload .emProject file

  • Sorry, I'm not seeing any errors in your project file or in flash_placement.xml. Are you able to upload the whole project so I can try to debug it here?

  • Do you have a bootloader present when you're debugging this? In other words, are you sure the crash is occuring in the application and not in the bootloader?
