We are attempting to test CSI IP on Agilex5 on AXE5-Eagle Arrow Development board, and find that the byte Location assignments on the mipi phy seems to have bug, as it does not allow us to use odd by...

Hi Wincent,

Thanks for your reply. We have been following the guidelines already.
There has been a bit of an update, we are now using byte 6 and byte 1.
I was having trouble to map byte 1 to link 0, but was able to compile when I changed the byte-1 allocation to Link-0 and Byte-6 allocation to link-0.
Additionally the byte number in the GUI, even after compiling the project is seen to be incorrect.
Please see attached screenshot for explanation.
To re-iterate the original request, the GUI cannot display odd bytes in the 'link tabs'.
I am using Quartus 24.2

BR,
Pushpraj Adhage

      Hi Pushpraj,

      Upon check with our internal development team.

      • The GUI display you see on Link x tab -> link x location,
      • it can only display even number. (if you put byte 0, 2, 4, 6 it is fine. If you put 1, 3, 5, 7 you will see it go to 0, 2, 4, 6).
      • Our team is fixing this issue, and the fix will be available in Quartus v24.3.1 in few month later (subject to change)
      • At the same time, we are filling a FPGA knowledge based article to inform other user about this behavior. Pending to be available within 1-2 weeks.

      At the meantime, To ensure that the entered byte location is correctly assigned, please verify that in the table showed in DPHY IP / IP Configuration tab Enabled Links section shows the desired byte location for each enabled Link.

      Hope this is clarified and work for you. Let me know if you have any further question.

      Regards,

      Wincent_Intel
