Dears,
some simple troubleshooting:
- with defective crystal you should NOT be seeing any 32kHz signal on CLKO (you might try to see crystal oscillations by the oscilloscope) - without clock, the zigbee chips appear as dead.
- if there's CLKO signal, probably the SPI communication is corrupted (some of MISO, MOSI, CE, SCLK and/or IRQ signals are disconnected, shortconnected or grounded).- in case on 13213 I would suspect those test pads below chip to be a problem.
Once all connections are OK, the initialization should go through.
