When I flash program using BLE DFU, application doesn't start

[MarcoR]

I'm tryng to load a simple example code with PC nRF Connect (v2.6.2) using the BLE tool.

I'm able to connect the programmer to DfuTarg and the zip package is recognized by the software.

The loading process looks like is everything ok, but the application doesn't start on target.

The LEDs that were on during the bootloader goes off and if I press the reset button on the board nothing happens.

NRF Connect gui still shows the target device named "DfuTarg".

Using the nRF Connect Programmer tool, I noticed that the application firmware has been loaded in the target memory.

I'm using two nrf52832 DK and the SDK 15.3.0 version.

Have you tried to debug the bootloader? Try building it again without optimization and start a debug session inside the bootloader. Then you can figure out through logging and breakpoints why the bootloader doesn't start the application. If you have any problem doing this, please ask and I will try to assist you.

Best regards,

I solved the issue setting the IROM1 and IRAM1 Start addresses as in the blinky example found in "nRF5_SDK_15.3.0_59ac345/examples/peripheral/blinky/pca10040/s132".
