CMOD A7 OOB project - mem test stamps on its own codespace!? in FPGA Posted March 15, 2020 well, I'll answer my own question. Basically, just changing to the correct ldscript.ld file fixed things. Initially Vitis complained about the board config, but I ignored it, rebuilt everything and now the build works fine. The working memory is internal to the FPGA, and the external SRAM can be tested fine with the demo code.
