Hi,
So I've made a post that I was unable to debug my app with the bootloader. But I've found out that it is entirely different problem. So my app is runnning whit FreeRTOS and I am using the buttonless bootloader debug example on the SDK15.0.0 with the softdevice compiling with armgcc. When I try to flash trough eclipse, the application restart but does not change.So I think that probably the flash fails.
Then I tried it on nrfGo studio and I get the message "Unable to erase UICR" when I try to flash my application. I did try to erase the UICR before but I don't think that is the problem. I tried reajustring my linker file since I thought that maybe I was writting on the bootloader. Since the bootloader starts at 0x72000 I've five the length of the flash.
Here is my .ld file of my application:
/* Linker script to configure memory regions. */

After a reset: When I flash the bootloader after a reset, if I send an image through the dfu service, it boots. If I flash direcly it doesn't since it does not pass the CRC check. So first I flash a working image through the DFU service and then I try to develop and debug the app by flashing normaly through my IDE/Jlink, but then nothing changes as described in the post.
Any help is appreciated.
