>ad9467 spi0.0: Unrecognized CHIP_ID 0xFF
This means that something went wrong with the SPI transfer from the AD9467.
Can you check if AXI-SPI received an interrupt:
Type:
root@linaro-ubuntu-desktop:~# cat /proc/interrupts
And post the output.
Are you using the AD9467 FMC card from ADI?
If I remember correctly there are some jumpers related to SPI can you check them too.
Greetings,
