Hi,
We have been prototyping on nRF52-DK and are moving to the final platform, an ISP1507 (embedding a nRF52810) mounted on a custom board.
We are working with the nRF Conenct SDK / visual studio code.
We need a debug probe for in situ programming / debug.
I've seen here that it needs to be j-link compatible.
Unfortunately, the jlink-base is quite expensive.
Is there any officially supported alternative suitable for a commercial application that would be cheaper ?
Kind regards,
Laurent
Hi Laurent
The nRF52 DK you already have would be the most cost effective debug probe for your design I would think. It already sports a J-Link debugger on the Interface MCU that is able to program and debug external devices (as long as they run at 3.0V). You can see this section in the DK user guide for more information on debugging external devices, and if the custom board does not have a 10 pin debug header you can connect it with VDD, GND, SWDCLK, and SWDIO like this to your DK to debug and program over the P20 header.
Best regards,
Simon
