NRF Connect 3.0.0 and Secure Bootloader

[abe]

Hi, I'm using a PCA10056 DK board to start new development. I try to program DFU secure bootloader and SoftDevice using nRF Connect 3.0.0
My issue:
- configure both hex files on programmer

- start programming (Erase and Write)

- the program procedure starts, but after few seconds the blue bar is freezed, and the nRF Connect stops work. (see video here attached)

- I must force the nRF Connect termination (using task manager), restart program and reconnect the DK boards but nRF Connect is not able to show correctly the FW inside boards

What I wrong?

Hi Abele, 

If you flash them separately do you see the issue ? Have you made sure you have the latest version (Programmer v1.2.0) 

I would sugget to use nrfjprog.exe command line tool to test.

Hi Hung, thanks for your reply.
I tried the above two sequences:

- erase chip; program bootloader; program softdevice.
- erase chip; program softdevice; program bootloader.

I have same issue in any case.
My programmer:

Using nrfjprog it's ok, maybe the issue on Programmer or nRF Connect??

Hi Abele, 

I was using Keil and Segger. Could you try the file I provided ? 

However could you confirm when you flash the bootloader_secure_ble_debug_without_bonds_s140.hex or flashing the hex file you generated, even though the nRF Connect app hang, if you reset the board, you can find that it works fine ? (adverting as DFUTarg, LED 1 and LED2 lid ?)

Hi Hung
I have already made test with your file

I will confirm that the board (after power cicle off/on) is working.
Have you seen the log file previously sent? There are many errors lines inside...

You are right, it was a lot of error in the log. But most of them was due to we can't access the debug port after programming. In my case it still work after a reset. 

For now I would suggest to use nrfjprog tool to do programming and verifying.

Hi Hung,
Have you any further news?
in the meantime I got many updates for nRF Connect and Programmer
The actual releases on the image below.
I have same previous issue and a further trouble, the target board will not resets under nRF Connect (see log file here attached), I must use a power cycle to start the DFU Targ application

Hi Abele, 

Unfortunately, I haven't got any update from the team regarding this issue. The solution for now is using nrfjprog still. You can make a batch script so that you don't have type the command all the time (you can program multiple hex file and trigger a reset, in one single batch command) . I personal prefer nrfjprog as it's much faster.
