ZCU102 - JESD204B linux driver installation and testing

[aymanhendawy]

Dear All,

I'm trying to test JESD204B linux driver by following this link "https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841739/jesd204b", but unfortunately I can't tell if it's probed successfully or not.

My setup is as following,

• ZCU102 board
• External linux source of linux-xlnx tagged at 2018.2
• Petalinux 2018.2

I have updated "system-user.dtsi" as the link above and below recommendtations,

• https://github.com/Xilinx/linux-xlnx/blob/master/Documentation/devicetree/bindings/misc/jesd-phy.txt
• https://github.com/Xilinx/linux-xlnx/blob/master/Documentation/devicetree/bindings/misc/jesd204b.txt

I can't get any "lane0_info", "lane0_syncstat", "reg_access", "sync_status", here's my output for sysfs,

dmesg have nothing related to jesd 

dmesg | grep jesd

Kindly, find attached

"pl.dtsi", "system-user.dtsi", "JESD Vivado block diagram.pdf", JESD .hdf file of the project "design_1_wrapper.hdf", and vivado .tcl design script "design_1.tcl".

Note: I can't attach .dtsi, or defconfig files, so I just added ".txt" extension at the end of each of these files, you just have to remove this ".txt" extension to open these files and compressed the ".hdf" file to "design_1_wrapper.7z"

I really appreaciate any help to get JESD works.

Thanks
