I am having some problems flashing the cu3 variant. I believe that I can do this before I have all the new DAC parts. I've used Zadig to update the drivers, and downloaded the newest artiq-board-kasli-cu3 6.7621.d9b01ed8
, but when I try to flash Kasli, it either it is unable to open the ftdi device, or shows me the error attached:
Please advise. Thank you!
