NRF_FAULT_ID_SDK_ERROR in application initialization

[Bruno]

Hi, 

I'm attempting to flash program a Nina B112 Bluetooth Module (from Ublox), which is built uppon a NRF52832 board and i'm attaching this module to a custom board.

I'm Using SDK version 15.2.0 and softdevice s132 version 6.1.0. I was able to compile and flash program Nina B1 EVK and it worked perfectly.

I'm coding and flashing programing in Eclipse IDE on windows 10 64 bits.

The problem is when i try to flash program my custom board. The code start running (when flashing the .out file for debugging) and it stops at the app_error_fault_handler in the NRF_FAULT_ID_SDK_ERROR case. I don't know how to monitor the log output in eclipse so i added a breakpoint to see the error_info_t var and it's displays

line_num = 0, p_file_name = 0 and err_code = 12

 I've done some codes before, using the SDK version 14.0, generated the images and flash programed this custom board and it worked with no errors. Because of that i don't think it's a hardware issue. I don't know where the problem might be. This application basically uses uart, flash storage (internal flash), BLE (Nordic Uart Service and Battery Service), ADC and App Scheduler.

Could someone please help me?

Thanks in advance,

Bruno.

Hi,

Do you have any debug log information? You can print the debug logs via UART or RTT by enabling the logging module in sdk_config.h. You should also change the log level to "debug", also in sdk_config.h.

Hi, thanks for the answer, 

Which log modules should i enable? (such as PDM_CONFIG_LOG_ENABLED, GPIOTE_CONFIG_LOG_ENABLED...?)

and by changing the log level, you mean change GPIOTE_CONFIG_LOG_LEVEL (for example) to level 4 (which is debug mode)?

I was about to finish configuring all logs as you suggested, but then i realized: will i be able to see logs?

The problem is that i use the UART for communicating to another micro and i don't have a j linker debugger to check RTT responses, can i see RTT messages over Pe Micro Multilink Universal debug probe?
