nRF52832 DK Programmer / USB?

Thanks for the update. I'm glad to hear that it worked. Normally, it should never be neccessary to enter bootloader mode on the DK.

I guess this was the issue - for some reason the bootloader was messed up.

Looks now like this

nRF Programmer is now also able to detect the device.

So I guess the issue is solved.

To sum the solution up:

1. Need to install Segger JLink Drivers > V7.94e and select "Install legacy USB Driver for J-Link" and uninstall the old one

2. Reboot

3. Switch DK-Board on and hold Reset-Switch

4. Immediately check for the Bootloader-Drive

5. Drag and Drop https://nsscprodmedia.blob.core.windows.net/prod/software-and-other-downloads/dev-kits/nrf5x-dk-files/j-link-ob-sam3u128-v2-nordicsemi-170724.bin to the bootloader drive

6. Switch DK board off and on

7. Check that COM-Port can be seen in device manager

8. Check availability in nRF Programmer

Thanks for the additional information. The LED will blink more rapidly when there is a communication issue. Please try to drag&drop the J-link binary to the BOOTLOADER drive as Turbo suggested. The binary can be downloaded at https://www.nordicsemi.com/Products/Development-hardware/nRF52-DK/Download?lang=en#infotabs.

devzone.nordicsemi.com/.../nRF-DK-Problem.mp4The J-Link will be there next week hopefully. I used various USB-Cabels such as my Jabra-Cable which works fine as data cable with my Jabra. So this should not be the problem. Those cables work also with older mobile phones on the same PC. I am confused because there is no USB-Detection at all.

One Step further: I have managed to get the bootloader. For some reasons I have not seen this before. This actually is available right after switching on and holding the Reset-Button. It vanishes after some time...

So it might make sense to flash the bootloader again...

When the programmer LED (the LED next to the interface MCU) is blinking and the USB is not enumerating, it usually indicates a problem with data communication. This issue can also occur if you connect a charging-only cable to a DK in a working setup.

When do you expect to receive the J-Link probe? It would be interesting to know if you experience the same problem with it.

There is no Mass Storage popup. It lights up LED 1 and the programming LED starts blinking.

Edited:

My fault. Bootloader comes up in that case!

Is that one of the older kits? These should pop up an USB mass storage drive when you hold down "reset" while plugging USB in. Then you need to copy the "interface MCU firmware" for your DK variant - see DK downloads page.

Note that this procedure does not apply to 3.x.x DK versions that use NRF53xx for the debug IF MCU. That is why its no longer documented in the DK stuff, but see infocenter.

Tried different USB cables and ports: same

Please try different USB cables and USB ports on your PC. The fact that the board powers on suggests that power delivery is fine, but there seems to be a problem with data communication.

Yes. Not returning anything. Also no USB detection going on. Just nothing.

Did also a reboot after driver installation.

Hi Andreas,

[quote userid="133664" url="~/f/nordic-q-a/111765/nrf52832-dk-programmer-usb/487088"]Installed JLink version does not match the expected version (JLink_V7.94e)[/quote]

This is the version the nRF Programmer has been tested and verified against, but it should normally work fine with other versions as well. Is 'nrfjprog --ids' still not returning anything?

Hi Vidar,

I installed a later J-Link driver and checked the option as described. However: the nRF programmer 4.3.0 now is telling me:

Installed JLink version does not match the expected version (JLink_V7.94e)

Hi Andreas,

Please check if you have the Jlink legacy USB drivers installed as discussed in this post: J-Link legacy USB driver required on Windows for some DK boards

Neither the nRF52840 Dongle nor the Thingy:53 comes with an on-board Jlink debugger, so they are not affected by this.

Best regards,

Vidar

I ordered a J-Link but not yet there so I tried plain USB. Question: do those older boards require a J-Link hardware in order to be flashed?
