Programing and debuging nRF9160

[Farouk]

Hi,

I am a beginner when it comes to using nRF products, my questions is:

Can I use any SWD probe to program nRF9160 SiP?

Can I use a USB to JTAG CHIP for programing the device?

Thank you in advance

Hello,

Can I use any SWD probe to program nRF9160 SiP?

No. The probe has to support ARMv8-M, since the application processor in nRF9160 is Arm Cortex-M33.

Some of the cheaper SWD probes may only support the older ARMv7-M (like Cortex-M4).

Can I use a USB to JTAG CHIP for programing the device?

No.

In general I recommend using a probe that has a clear support for nRF9160. Remember that even if the hardware does support it, the software must do it as well.

Best regards,

Michal
