Getting "Error when running fw program" when trying to write .hex file

[Bheam]

Hi, getting this not very descriptive error when trying to upload hex file. I've made the .hex file in platformio. Sounds like i'm missing some software?

Any clues?

Device NRF52840 dongle (nRF6829, 2.1.0, 2021.51)

Hi,

Is the hex file from platformio built for running on the nRF52840 Dongle? The dongle comes programmed with a bootloader + MBR, which can't be overwritten by the application if you want to program it through the USB port.

If your hex-file is the green box in nRF Connect Programmer app, this looks a bit high in flash. Can you hover over it to see the start and end address of the application?

Best regards,
Jørgen
