nrfjprog - read model number

[db_lw]

Hello,

I was wondering if it is possible to read the model (e.g. NRF52810_xxAA_REV1) from a chip with nrfjprog?

In production we use nrfjprog to program our devices and so far we had only one type of nRF52 but in future we will have different variants.
So we would like to check if it's the right chip to fit the firmware.

Thanks in advance!

The idea is to just read FICR data (example: NRF52840 CAA):

>nrfjprog --memrd 0x10000100
0x10000100: 00052840

>nrfjprog --memrd 0x10000104
0x10000104: 41414330                              |0CAA|

Not sure how useful this would be, though.

Thanks Turbo J that is exactly what I was looking for!

I want to use it to make sure that e.g. a firmware for nRF52811 is not programmed on nRF52840.
