Read SoC device type by nrfjprog/J-Link Commander

[John]

Hi, 

Is there any command for reading the type of Nordic SoCs (e.g, nRF52833 or nRF52840) that is going to be programmed by nrfjprog/ J-Link Commander?

Thank you!

Hi,

There is not dedicated command for this, but you you can read the device variant from the FICR registers INFO.PART and INFO.VARIANT.

With nrfjprog:

$ nrfjprog --memrd 0x10000100

$ nrfjprog --memrd 0x10000104

Or with Jlnk commander:

> mem32 0x10000100 1

> mem32 0x10000104 1

Best regards,

Vidar

Edit: A colleague pointed out to me that nrfjprog does actaully have a dedicated command to check the device version now: 

$ nrfjprog --deviceversion
