Hello, 

I am trying to run the VCU118+AD9081 https://wiki.analog.com/resources/eval/user-guides/ad9081_fmca_ebz/quickstart/microblaze quickstart. 

At power on, the HMC_STATUS light is on, on the AD9081 eval board. 

During microblaze boot, the light stays on and the ad9018 is not visible on the iio_info

I have tried the following builds, they all have the same outcome: 

2023-12-08 - 2022_R2 : 2022_r2_vcu118_ad9081_m8_l4.zip 2022_r2_vcu118_ad9081_204c_txmode_10_rxmode_11.zip

2021_07_27 - 2019_R2 : 2019_r2_vcu118_ad9081.zip

iio_info command:

# iio_info | grep iio:deviceiio:device0: hmc7044

Here is the UART boot output from the 2022_R2 : 2022_r2_vcu118_ad9081_m8_l4.zip build:
