AD9081-FMCA-EBZ-A3 & VCK190 JESD Initialization

Category: Software
Product Number: AD9081-FMCA-EBZ-A3

I am trying to bring up the AD9081-FMCA-EBZ-A3 board with the versal VCK190. but am running into issues with the JESD initialization.

I've been using the prebuilt files from the versal-vck190-reva-ad9081 and versal-common directories on the latest SD card release.

On my first attempt, I tried using the prebuilt BOOT.bin with the precompiled Linux images (devicetree & kernel).  The JESD would fail and with a message that the JESD settings (M, L, F, etc) in the devicetree didn't match the HDL.  I found an example make command in the HDL project with the right JESD settings, recompiled the BOOT.bin, and tried again with the same kernel and devicetree.

make JESD_MODE=64B66B RX_RATE=24.75 TX_RATE=24.75 RX_JESD_M=4 RX_JESD_L=4 RX_JESD_S=2 RX_JESD_NP=12 TX_JESD_M=4 TX_JESD_L=4 TX_JESD_S=2 TX_JESD_NP=12

Now those errors are absent, but the JESD FSM failed on the link_enable state.

I tried the same AD9081 board with a zcu102 and the precompiled files and that worked.  I'm not sure if there's a variable missing from my make command or it's some other issue.  I've attached the dmesg output.
