Anyone have any experience bringing up the BLUENRG-M2 chip?

Running into lots of problems getting the BLUENRG-M2 to work standalone. When I hook up the expansion board (BNRG2A1), everything works, but not with this chip on my PCB. Verified power and signal wires. Every connection seems fine and I was able to flash the firmware v3.2.0 using the flasher utility via SWD just fine to the BLUENRG-M2.

Any thoughts?

Try to step by step debug with the SWD ?

Possibly an issue on crystal ?
