Hi Sonyan, In general, we don’t recommend disabling the UART log, since it removes an important recovery and debugging channel. If you still need to disable it, please try to disable the status of /fiq-debugger in device tree. This will stop console output during the kernel and system stages. For U-Boot, we recommend using CONFIG_SILENT_CONSOLE to silence its output. Thank you.

Hi, Here are a few ways to reduce radio frequency interference (RFI): 1. Disable USB 3.0. In your case, you can directly use a USB 2.0 port to connect the camera. 2. Improve signal shielding. Try adding metal shielding (grounded) between the Wi-Fi network card and the motherboard. 3. Switch to a USB Wi-Fi card and use a USB extension cable to move the USB Wi-Fi card away from the USB 3.0 port.

hello @sonyan11, apologies for the late reply, the usb 3.0 has 2.4ghz signal that might disrupt, please try using wi-fi 5ghz and see if the problem persists

hello @sonyan11 For TB3 use the following commands Reset usb 2.0 hub: echo 1 > /sys/kernel/debug/usb/fd800000.usb/hub_reset Power off and power on usb 2.0 hub device: echo off > /sys/kernel/debug/usb/fd800000.usb/hub_vbus echo on > /sys/kernel/debug/usb/fd800000.usb/hub_vbus Power off and power on usb 3.0 hub device: echo off > /sys/kernel/debug/usb/fd000000.dwc3/hub_vbus echo on > /sys/kernel/debug/usb/fd000000.dwc3/hub_vbus

hello @sonyan11, for uvc option, the config has to be set with the command below before make menuconfig tinker board linux 4.19: make ARCH=arm64 tinker_board_2_defconfig and then make menuconfig
