Amiga 500 -colors are displayed incorrectly | black is dark red #13

Closed sascha70 closed 1 year ago

Hello community,

unfortunately a bug is driving me crazy with the Amiga 500.

Unfortunately, the colors are displayed somewhat incorrectly for me. What should be black is dark red. I used the Beta54 version from JanBeta and the version from main tree 20211224_c97f06a release. All have the same problem. The adapter is from LinuxJedi (https://github.com/LinuxJedi/AmigaRGBtoHDMI/tree/main/Amiga500CPLD).

Do you have a solution?

Thanks

Looks like one of the red signal is missing or shorted together? I would inspect and check the soldering of the red signals and traces on the adapter itself.

Did you build the adapter yourself?

Also, check whether you get the same issue on the RGB video output.

They were right. It was the plug-in lead from the Pi Zero. I checked it with a Pi 3 A+ and it worked great.

Thanks for your great project!
