Hello,

Please save the configuration with the 12V PDO first, it will generate a *.cyacd, *.xml and *.c file, and replace the config.c file in the project with the modified one. Once you do that, kindly rebuild the project and program the firmware file.

If you still see 20V, it could be possible that the PD contract happens at 20V even with 12V added as the sink may be requesting for the same.

Best Regards,
Sananya
