I download the ADI-Kuiper image from swdownloads.analog.com/.../image_2024-06-18-ADI-Kuiper-full.zip, then use Raspberry Pi Imager to burn image to SD card.
As my undertanding, CN0566 contains two adar1000, but the dts file only contain adar1000_0@0 BEAM0, there is no BEAM1? is it correct?
github.com/.../rpi-adar1000-overlay.dts
Also the config.txt, the SPI is disabled, adar1000 is SPI interface, what is the SPI setting of Raspberry pi?
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on
If we want to setup 4 SPI interface from Raspberry GPIO, each SPI control 4 adar1000, how to setup config.txt/device tree/adar1000 driver?

Thanks
