Hi Taz I wanted to let you know: 1: I got them working perfectly again thanks to your help.👍👍 2: The problem was with the firmware, which always gave an error when updating.🤦‍♂️ #: I downloaded the firmware twice from the official Teclast website. #: I downloaded it the third time, and this time it updated completely. #: It's possible that some files got corrupted when I extracted them. 3: How do you connect the TF UART adapter? 4: Why did you install this Armbian operating system on the Allwinner A733? #: Does it work better? Is it smoother than Android on this tablet? Thanks

@Delutto Thank you for your contribution! Your changes have been successfully merged to my repo https://github.com/cdhigh/armbian_sv6256p Now the driver should work with kernels from 6.0 through 7.x.

This issue is not from u-boot but rather a board config Please see this https://github.com/armbian/build/pull/9333 and use edge kernel instead, stable doesn't include this fix Cheers !

Hello everyone. I made a direct connection between the 5V from the motherboard and the 5V from the USB ports to try and overcome the current limitation of the USB ports. However, something went wrong. I undid this direct connection, but the motherboard is still shorting the USB ports. I believe the short circuit is in that ADG3T port. Does anyone have any idea what happened? I didn't even connect anything to the USB port. Thanks.
