Hi Jeff,

The fact that it is a module should not matter. But you need to have a fairly up to date Segger software and nrfjprog so that it can actually recognize the nRF52833. Can you try updating to the latest SEGGER J-Link software and documentation pack and nRF Command Line Tools? With that in place, nrfjprog should recognize the nRF52833 as a nRF52 family device.

My thinking is that I can do the following:

Figure how the BL653's self description during nfrjprog / JTAG negotiation differs from PCA10100
Clone PCA10100 info (how many places?) and name the copy BL653
Modify the parts of the new BL653 Config such that nfrjprog will recognize the BL653 HW as "within the nrf52 family" and write the program

Am I on the right track? It'd be helpful to identify the places to be modified.
