    Yes, that is how I connected it first time when I flashed osf (i thought i need all 4) I have done it multiple time playing with settings in java configurator, but now nothing works. I will have a chance to test my st link with other motor and laptop soon. If it not gonna work I will blame st link

    Hi. I'm having similar problem, except that I managed to flash my controller with OSF in the past, recently I tried to update the osf version to the newest and all I get is exact same error. I think I tried all possibilities. Nothing worked for me if you find any solution please let me know
