I have installed a project in my old module. It works fine. Now i have bought a new module in oktober 2022. The same project doesn't work anymore. Have there been changes in the module?

The availability of FLASH devices in distribution channels come and go. Sometimes, when a manufacturer does a board production run a part isn't available and a substitute has to be made. Sometimes, alternate parts don't behave exactly like the original part. Ideally, a board vendor would take the time to find and address compatibility issues before releasing new boards onto the market. Keep searching this site along those lines. You are not the first customer to have a problem with new boards having compatibility issues with designs for older boards.
