nRF52840 DONGLE debugging

Question

Hi, 
 
 I am developing a project using the nRF52840 DONGLE. As part of the process, I need to be able to debug my code, so I am using IAR and a J-TRACE PRO for that. The problem is, when I download any program that uses BLE, I just cant debug, as the firmware never reaches main on startup. When I download any example that doesn't uses BLE, such as the USB Generic HID, it works fine. So, what could possibly be the error? I have already tried the sugestions on this tutorial , but got no results. Another curious thing is that I can't download the SOFTDEVICE via nRFGO, becouse it says that "No device detected, or readback protection may be set". When using nRF Connect, I can read the device memory and program the softdevice. 
 The example I am trying tho download to my dongle is the ble_app_uart_c. I did change the board define to PCA10059 and commented the UART initialization for bypassing the pins definition error.

Are you including the softdevice in the IAR build? These are the steps we use, in particular the using Flash Loader was not an option: 
 Options->Debugger->Images: 
 Download Extra Image [ Checked ] 
 Path: blah\blah\s132_nrf52_6.1.0_softdevice.hex 
 Offset: 0 
 Options->Debugger->Download: 
 Verify Download [ Checked ] 
 Use Flash Loader: [ Un-Checked ] 
 This works as-is with the vanilla linker icf file and standard SoftDevice settings (Nordic Uart example based) which doesn't need editing: 
 Debugging code with softdevice interrupts running using stepping is another issue, but at least the above lets the code run to main() and beyond with the ability to break on a breakpoint once pretty much anywhere. There are a few posts on debugging with running code beyond the first breakpoint.
