Can't program a NRF52840 device from a (NRF52833-DK)

[pablitorun]

I have a NRF52840 based custom device that I can program just fine with a NRF52840-DK.

However, when I try to use a NRF52833-DK I can erase and flash the softdevice just fine, but when I try to program our application the device will not power up

and will not respond to any nrfjprog commands giving the following error.

nrfjprog --program _build_debug/app_and_settings.hex -f nrf52 --sectorerase --log
ERROR: [SeggerBackend] - 10 second timeout elapsed, no time left to wait for debug port to power up.
ERROR: nrfjprog failed for an unknown reason. Run the same command again with
ERROR: argument --log, contact Nordic Semiconductor and provide the generated
ERROR: log.log file to them.

I can then recover the device by switching back to a NRF52840-DK

Any idea what is going on?

Hi,

Any nRF52 series DK should be able to program any nRF52 series device. Which revision of the DKs are you using, and which revision of the nRF52833 do you have on your custom board? Also, which version of nRF Command Line tools and the Segger J-Link driver do you use? And does updating to the latest help?
