TE0820 Module Compatablity

I have a currently implemented project using TE0820-02-03CG-1EA module. Looking to move this project to TE0820-05-3AE81MA module.

The question is, will the vivado reference design for the 03CG board be valid and still work with the 3AE81MA module? At the very least might have to change RAM settings. But I'm mostly unsure about the CPLD configuration. Or am I destined to have to rebuild from the ground up from the new reference design? Thanks for any help.

Hello mer,

since the main chip is the same, it is likely that the design will work with the new board or rather that you can adopt most of your old stuff. Except for the things that have changed :)
The DDR chip (model and size) - You can compare your settings with the ones we have online on the current reference design 2023.2 - TE0820-05-3AE81MA is supported:

Also the qspi flash and emmc chip have changed, but they will probably work without many design changes.

More troublesome could be the new cpld firmware/different firmware versions(default/optional). How your application reacts to that depends on how the relevant signals are controlled on your carrier, especially the configuration signals.

Will the 03CG board's vivado reference design be compatible with the 3AE81MA module

Hi,
yes you can use board files from:
test_board\board_files\TE0820_3EG_1E\2.0
