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.

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

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
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...

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 ?)

Hung,

I compile the project locate on \examples\dfu\secure_bootloader\pca10056_ble_debug as you suggets, but I have same issue
No issue with your file.
What IDE are you using to compile the sample?
I'm using IAR 8.30.1

Hi Abele,

I was thinking you flash the precompiled hex file for the bootloader located for example here: \examples\dfu\secure_bootloader\pca10056_ble_debug\hex

I have managed to reproduce the issue you are experiencing with the bootloader .hex provided at the secure_dfu_test_images folder.

I'm not sure what could be the problem with the hex provided at secure_dfu_test_images . I will report this error to our developer.

But could you try to compile a bootloader project and use the hex file there instead ?

I attached here the hex file I compiled it can be flashed with the softdevice with no problem. devzone.nordicsemi.com/.../nrf52840_5F00_xxaa_5F00_s140.hex

RE: NRF Connect 3.0.0 and Secure Bootloader

abe — Thu, 22 Aug 2019 12:14:51 GMT

Hung,
the precompiled hex file of bootloader example don't include SoftDevice (\nRF5_SDK_15.3.0_59ac345\examples\dfu\secure_dfu_test_images\ble\nrf52840bootloader_secure_ble_debug_without_bonds_s140.hex).
Have you seen the log file on my previous post?

In any case, here attched the hex files I use

devzone.nordicsemi.com/.../bootloader_5F00_secure_5F00_ble_5F00_debug_5F00_without_5F00_bonds_5F00_s140.hex

devzone.nordicsemi.com/.../s140_5F00_nrf52_5F00_6.1.1_5F00_softdevice.hex

Hung Bui — Thu, 22 Aug 2019 11:19:38 GMT

HI Abele,
Please don't use the precompiled hex file. The precompile hex file already include the softdevice.

Please try testing again with a hex file that you build from the bootloader project. If the issue persist please send us the 2 hex files that you use.

Hung,
I'm using the default hex files on nRF5_SDK_15.3.0_59ac345.

Just today my nRF Connect an Programmer were updated (see image).
I tried but I have same issue.
The log file has many more details, also for errors; here attached the file.

Hi Abele, could yo provide the hex files you used so we can test her ?

Hi Hung,

Jlink version 6.44
No, If I load SoftDevice and Blinky example I have no issues.

RE: NRF Connect 3.0.0 and Secure Bootloader

Hung Bui — Wed, 14 Aug 2019 11:08:26 GMT

Could you tell the Jlink version you are using ?

If you combine softdevice hex and normal application hex do you have the same problem ?

RE: NRF Connect 3.0.0 and Secure Bootloader

abe — Tue, 13 Aug 2019 11:54:44 GMT

Hi Hung,

yes, if I flash the files one by one i'ts all ok.
I'm flashing the BootLoader hex generated from your example \nRF5_SDK_15.3.0_59ac345\examples\dfu\secure_bootloader\pca10056_ble, and softdevice here \nRF5_SDK_15.3.0_59ac345\components\softdevice\s140\hex

RE: NRF Connect 3.0.0 and Secure Bootloader

Hung Bui — Mon, 12 Aug 2019 08:44:37 GMT

Could you give some more information regarding the 2 logs file. I can see that you were flashing the hex file one by one and it was successful ?

If you flash the stock bootloader example instead of your bootloader do you see the same issue ?

Hi, the nRF Connect stops working and I'm not be able to save the log file.
Here below the screen of log when both hex file are programming.
Attached the other 2 logsdevzone.nordicsemi.com/.../2019_2D00_08_2D00_09T14_5F00_27_5F00_46.838Z_2D00_log.txt devzone.nordicsemi.com/.../2019_2D00_08_2D00_09T14_5F00_30_5F00_18.057Z_2D00_log.txt

RE: NRF Connect 3.0.0 and Secure Bootloader

Hung Bui — Fri, 09 Aug 2019 13:52:58 GMT

I just updated to v1.2.1 and it works fine for me here. Which Jlink driver are you using ?

When you programed the first hex after erasing it worked ?

Could you provide the logs (click "open log file", when you do 2 hexes at the same time, and when you do one at a time)

RE: NRF Connect 3.0.0 and Secure Bootloader

abe — Fri, 09 Aug 2019 13:03:58 GMT

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??

Hung Bui — Fri, 09 Aug 2019 12:24:41 GMT

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.
