On a Xilinx ZCU102 dev board, plugged into the 9009 FMC eval
Board boots but the IIO device does not show up.
Confirmed SD card files were copied and pasted to boot directory. But the instructions in the U-Boot section resulted in failing the boot process thus reverted back to the default files.
What would cause IIO device to not show up and what other steps can be taken to resolve?
The likely issue is the VADJ voltage is wrong. You likely have an early board. See here: https://ez.analog.com/linux-device-drivers/linux-software-drivers/f/q-a/99195/can-t-see-adrv9009-from-linux-zcu102…
Do you have the card in slot HPC-1?
can confirm that the card is in HPC-1 slot
Do any IIO devices appear? `iio_attr -a -d` on the board will list them.
that command is not recognized. However, if I do
iio_info | grep iio:device
It returns `ams` and `ad7291`
Also, FYI with the board booted, the PS_AUX LED is red and the PS LED is flashing.
