spi – Qualcomm QCA7000 with Raspberry Pi 4b+

I’m attempting to connect a RED BEET Qualcomm QCA7000 board over SPI to a Raspberry Pi 4b. I’ve added the dtoverlay=qca7000 to the config.txt and wired up the board with the pi GPIO pins according to this diagram.

However, dmesg only ever prints an error when loading the driver.

bperry@raspberrypi:~ $ dmesg | grep qca
[    2.362388] qcaspi spi0.0: ver=0.2.7-i, clkspeed=12000000, burst_len=5000, pluggable=0
[    2.362534] qcaspi spi0.0: Using random MAC address: d2:84:d7:da:e3:a9
[    2.362604] qcaspi spi0.0: Invalid signature (0x0000)
[    2.362636] qcaspi: probe of spi0.0 failed with error -14
bperry@raspberrypi:~ $

I’ve verified, reverified, unplugged, replugged the wires but I never load the driver correctly. I’m not sure what I’m missing. Could anyone provide any insight into figuring out what is going wrong, or have insight into wiring GPIO on Raspberry Pi a QCA7000 board as a ethernet interface?

Thanks for any help. Here is the document discussing hooking up the board to a pi in full.
