hello @Jovan, was the led (led1) on while using? please check if you're able to use the adb with mask2 cap on while booting?

hello @Jovan, 1. the connection should be type c port (tinker board 3n) to type a port (macbook) 2. both the jumper caps need to be removed 3. no need to adjust mask1 dip switch

hello @Jovan, please remove the yellow jumper cap, and re-do the procedure (connecting tinker board 3n to the computer) again booting without the jumper cap attached so the tinker board 3n can start on uboot and the board should be in ums mode

hello @Jovan, the cc logic controllers between tinker board 2s and tinker board 3n are different -- for tinker board 3n, if both the ports connected are type c port, the controller will not be able to recognise which port should be in host mode and which port should be in device mode. for tinker board 3n i would recommend to connect type c port from tinker board 3n to type a (macbook)
