Hello. I tried to install the firmware update and dashboard for my TB1 and the program read, " Evaluation Copy" not for sale. I continued, but the program was not recognized. I followed the links on the official Khadas upgrade page. I then uninstalled and deleted everything and attempted to re-install the original driver, again from the Khadas website, and the Theyscon driver and XMOS will not load. The unit is working, I presume with the Windows driver. Any help or advice would be appreciated.
