Received an error: 0x00000003 after programming softdevice, bootloader, and application hex files

I am testing secure DFU with hex files under D:\nRF5_SDK_16\examples\dfu\secure_dfu_test_images\ble\nrf52832 folder. After programming softdevice, bootloader, and application hex files through J-Link Commander script, Received an error: 0x00000003 occurred.

What is meaning of error code 0x00000003?

[Jared]

Hi,

That's NRF_ERROR_INTERNAL. Can you check which function that returns that error? It's not returned by sd_softdevice_enable().

regards

I try to add debug message to check which function that returns error code 0x00000003. But J-link RTT can't show any debug messages related to bootloader.

I can see RTT log messages if I use nRF5_SDK_16.0.0\examples\dfu\secure_bootloader\pca10040_s132_ble_debug. What is difference between pca10040_s132_ble and pca10040_s132_ble_debug project?
