0 JColvin Posted August 13, 2020 Share Posted August 13, 2020 Hi @Paul Chang, I have reached out to ask about this; it looks like that other DDR chip on the newer Zedboard has a slightly different memory configuration than is normally present. From what I can tell, the newer board is supposed to have the same memory configuration 16 Meg x 16 width x 8 banks, but FGBA code is indicating the DDR chip would have a 32 Meg x 16 width x 8 banks. I don't have one of these newer boards so I can't test this out for myself though. Thanks, JColvin Link to comment Share on other sites More sharing options...

Question
Paul Chang
Dear Sir,
We have two zedboard (One version is 2012 and another is 2019)
When I run the ZedBoard FMC Pcam Adapter One to Four Camera Demo example.
Old version board is no problem and new version board can not work.(Uart does not print anything and sometimes can not access ddr and ip address)
It is currently suspected whether it is caused by the difference in DDR.
(2012 zedboard's DDR)
(2019 zedboard's DDR)
We have tested the OOB demo from website and bundled SD card.
Website's image seem fail.
Bundled SD card is ok. (see attach log file)
What's different between two version of zedboard?
How to solve this issue?
Best Regards,
Paul
