ZCU102 - JESD204B linux driver installation and testing

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,

 

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