Couldnt find solution on gowin webite or google. After installing gowin IDE i'm getting an error creating new project : "Directory xxxx has null character". This happens if directory has spaces "user name". This works if im using non space folders. Cannot add this bug since i'm using education license.

thanks

Hello, the example of SDRAM usage doesn't work. The pins are not compatible with Tang Nano 20K and the IP used by this example is the old one. I wasn't able to run the example even after having fixed the pins Can you please provide the correct SDRAM example in github ?

Read litex_example, it's easy to test the sdram. image

I'm looking for Verilog example. As I said, there is one example "SDRAM_Controller_GW2AR-18_RefDsign" which is added but it doesn't work and it uses the old IP

I am also looking for example of how to use the SDRAM. Any news on this topic? A how-to example?

Any examples on how to read the SD card?

I did also get the same problem with the latest version but rolled back to an older version of the GoWin software and then it worked.

Hi all, Thank you for your reply. I am unable to find the older version tool on the Gowin website. Can you send me the link to install it?

Thank you. Viru KM
