TEBF0808-04A (TE0807-02-4BE21-AK) Displayport issues
« on: December 18, 2020, 05:44:56 PM »

I'm trying to build and test a graphic linux image for the TE0807-02-4BE21-AK with Qt and X11 but my displayPort doesn't work.

I've started from the 2019.2 prebuilt starterkit and build an image using petalinux with Qt and X11 packages groups enabled.

After booting the board I got the following issues, do you know how to solve this issue ?

Starting Xserver
Starting Dropbear SSH server: dropbear.

Starting internet superserver: inetd.
Starting syslogd/klogd: done
Starting tcf-agent:
X.Org X Server 1.20.1
X Protocol Version 11, Revision 0
Build Operating System: Linux 3.10.0-327.el7.x86_64 x86_64
Current Operating System: Linux starter-project 4.19.0-xilinx-v2019.2 #1 SMP Fri Dec 18 10:18:54 UTC 2020 aarch64
Kernel command line: console=ttyPS0,115200 earlycon clk_ignore_unused earlyprintk root=/dev/mmcblk1p2 rootfstype=ext4 rw rootwait cma=1024M

I also get these errors during the boot, not sure if they are relevant or not :

did you use our FSBL modification fir SI5345 configuration? Xilinx default FSBL will not initilise SI, so reference clks for the GTR are missing.

Please try out prebuilt binaries of the reference design, this should work.
Starterkit Design includes also FSBL template with our changes which can be load as local repository into Vitis

Hi John,

Thanks for your answer.
I've changed my FSBL for the prebuilt  one and it worked.
