Flashing a hex file (peripheral_lbs example built with vscode using NRF connect SDK) works when flashed with NRF Connect Desktop Programmer, but does not work when flashed with vscode directly.

Hi Dejans, I can run the peripheral_lbs sample on the dongle without any modifications if I flash using NRF Connect Programmer. I just gave an example. Even the hello world program has the same issue. I think my question wasn't clear. I was able to flash a program with NRF Connect Programer, but not with the jlink debugger and vscode.

Anyway, I solved it by making the following changes:

1. Added CONFIG_BOARD_HAS_NRF5_BOOTLOADER=n to prj.conf file

2. Changed #include "fstab-stock.dts" to #include "fstab-debugger.dts" on boards\arm\nrf52840dongle_nrf52840\nrf52840dongle_nrf52840.dts file

Hi,

nrf52840 dongle is not listed as supported for peripheral_lbs sample.

Best regards,
Dejan

Hi Dheepan,

Apologies, I misunderstood your issue.

I'll let the DevZone engineers help resolve this for you!

Hi Sam, Thank you for your reply.

Unfortunately that link does not answer my question. I am not trying to flash using the dongle. I am trying to flash a program onto the dongle. I do have a Jlink debugger, and a 10-pin tag connect plug of nails with me.

My issue is that flashing with the debugger works with hex files in the examples with nrf5 sdk. (for example: ble_app_blinky_pca10059_s140.hex file from nRF5_SDK_17.1.0_ddde560\examples\ble_peripheral\ble_app_blinky\hex.

But when I build an example with NRF Connect SDK, the hex file flashes successfully, but never boots up.

Hi Dheepan, VS Code only supports J-Link based devices like our DKs. This is detailed in a similar support ticket here: nrf52840 dongle not found in "connected devices" in vscode
