Part Number: AWR2944
Other Parts Discussed in Thread: UNIFLASH

Tool/software:

I want to develop the AWR2944 chip, and I have a PCB board with a 2944 chip and a Zynq chip for internal demands.

How can I switch the SOP mode of the 2944 without using hardware jumpers?
Is it feasible to use the Zynq control the voltage levels of the SOP pins to set SOP (since I noticed that mmWave Studio can set the SOP value without jumper changes)?
For future firmware updates via UniFlash:
Will I need to reset or reboot the 2944 for the SOP mode to take effect?

Hello Qiang,

1) The SOP pins can be connected to GPIO pins of the zynq chip and you can drive it high and low.

2) Yes you need to reset the device as for OTA you need to have a dedicated boot manager.
