Didn’t you forget to put the jumper on the JPROG pins on the controller board?

I dident know that. Have just followed the readme file found withe the driver becouse i cant acsses the instructions. I will try tomorrow. Shall the jumper be there all the time or just även updating firmware?

[quote=“Tall_pinetree”]Shall the jumper be there all the time or just även updating firmware?[/quote]It’s only needed to upload the firmware but you can let it all the time (when removed it prevents any overwriting of the firmware). After uploading the firmware don’t forget to execute a “Restore Failsafe” followed by “Store memory” on the LCD.
