DK onboard J-Link support for different devices

[jeremyherbert]

Hi,

I am looking at setting up some of our team with the ability to flash our custom devices that contain various chips (nrf52, nrf53, nrf91). Assuming the SEGGER software is up to date, solder jumpers are set correctly and the voltage levels match, are there any restrictions around which DKs we can use with the "Debug Out" for different Nordic chips? For example, can the nrf52dk program an off-board nrf9160 (incl modem update)? Can the nrf5240dk program an nrf5340? etc

Thanks,

Jeremy

Hi

The nRF52 series sue the Arm Cortex M4, while the nRF53 and nRF91 both use newer Arm Cortex M-33.
Our older debugger chips can therefore only program the nRF52 chips.

So the limitation that the nRF52 based development kits can only program the nRF52-series.

An exception is the new version of the nRF52840DK v3.0.0, which should be able to program nRF53-series and nRF91-series.

EDIT: See the "Debug Output" for each Development Kit for information on which Developement Kits can program what: https://infocenter.nordicsemi.com/topic/ug_nrf52840_dk/UG/dk/hw_debug_out.html

How does it look for nRF54H20?

Is it possible to flash/debug it via jlink probes of devkits like nrf5340dk or nrf54l15dk ?

Hi Christan,

Please make a private ticket to ask this.

Thanks!
