Nordic Board is stuck in reset

Hello again,

Could you try to measure the supply voltage of the kits, as well as the supply voltage on the VDD input to the chip?

Regards,

Elfving

Hello Elfving,

That is correct, no flashing light and drag and drop did not program the board,

Kind Regards,

I presume then that you do not see LED flashing on the board like it should? If it was flashed correctly using this drag-and-drop method, it might also seem as if it is simply removed from the drive.

Hello Elfving,

I tried dragging the hex file into the JLink window, but it simply removes it. As discussed above, I am not able to use the SEGGER programmer and nrfjprog.exe.

Please find attached the JLink window and powershell outputs

Kind Regards,

ZahidM

Hello Zahid,

If a JLINK flashdrive appears when you start the board normally (not using bootloader mode) then a hex-file is fine. Is the flash drive you see appearing called bootloader?

Here is a hex file: devzone.nordicsemi.com/.../4466.zephyr.hex

Hello Elfving,

Here is a closer look at SB9. It does not appear to be cut.

Is it possible you could please attach a blinky bin file that I could use? I guess this can be dragged into the BOOTLOADER drive?

Kind Regards,

ZahidM

Hello,

Could you see if SB9 has been cut, or simply give me picture with a closer look at that part?

And could you try to flash the standard NCS Blinky example to the board and see how it reacts?

Regards,

Elfving

Hello Elfving,

On switching the board ON, the flash drive appears, LD5 comes on and the four LEDs are very faintly on. Please see attached photo of board,

Kind Regards,

ZahidM

Hey Zahid,

Are the LEDs still lit the same way as before? Are you still not seeing a flash drive appear when you plug it in?

Could you try reinstalling your J-Link drivers? And if that doesn't help could you send me a photo of the board?

Regards,

Elfving

Hi Elfving,

I placed the board into bootloader mode and saw LD5 started a slow blink. I then dragged 'j-link-ob-sam3u128-v2-nordicsemi-170724.bin' into the BOOTLOADER drive.

LD5 started to blink faster after the file had finished transferring.

I then power cycled the board and tried to run the '--recover' command and still saw the same error :(

PS C:\Program Files\Nordic Semiconductor\nrf-command-line-tools\bin> .\nrfjprog.exe --recover
ERROR: Unable to connect to a debugger.
ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.
NOTE: For additional output, try running again with logging enabled (--log).

Hello again,

Could you try to reflash the firmware in bootloader mode?

In order to do this, first download the interface MCU firmware from here. Then enter bootloader mode on your nRF52DK by keeping the reset button pressed while powering up the DK until LED (LD5) starts to blink. Then you should see a drive in windows explorer named BOOTLOADER. Drag and drop the bin file you've downloaded into the bootloader.

Regards,

Elfving

Hello Elfving,

I tried it on one other V2.0.0 board, with the same result,

Kind Regards,

I see. Thanks for checking.

Did you say you've tried this on multiple version 2 boards?

Best regards,

Elfving

Hello Elfving,

Here are the results of --recover and --reset. The board are not responding at all to the nrfjprog command. Any command gives the same response.

PS C:\Program Files\Nordic Semiconductor\nrf-command-line-tools\bin> .\nrfjprog.exe --recover
ERROR: No debuggers were discovered.
NOTE: For additional output, try running again with logging enabled (--log).

I am also not able to run with --log as seen below:

PS C:\Program Files\Nordic Semiconductor\nrf-command-line-tools\bin> .\nrfjprog.exe --reset --log
WARNING: Logging is unavailable. nrfjprog.exe does not have write

Hello again,

That is odd, considering that the differences between the versions aren't that extensive. I am looking into it though. Since you are saying "boards", I assume you've tried this on multiple boards of these versions?

Is Segger or nrfjprog giving you any error? Are you able to reset the board using nrfjprog --reset? Have you tried the NCS Programmer application?

Regards,

Elfving

I looked at the problem a little further and observed the following: Using the latest SEGGER (v7.60g) and nrfjprog(10.15.1 external), I am unable to program the v2.0.0 Nordic Boards. These were put into the 'reset' state using the command discussed above.

When I remove the SEGGER probe and external supply, and then plug in a USB cable, the green light (next to the MCU) is on and the four LEDs are very faintly on but I am still unable to program the board with the SEGGER and nrfjprog.

If I use v2.1.0 Nordic boards, I have no problems and can program them via the USB cable using nrfjprog.

So the problem is that it may not be the hex file but I need some help to program the older v2.0.0 boards?

Hello Zahid,

Could you tell me a bit about final_image.hex? My first thought is that there is something wrong with it.

Best regards,

Elfving
