USB port *1 5V DC-IN IR receiver Reset hole OS: Ali YunOS Steps 1, connect UART from mainboard test points, (I can only find M17's UART port) 2, build u-boot follow q200.rst in u-boot doc, use VIM2 config and use VIM2 fip blobs (hope that works) 3, build Arm64 debian bookworm with default debian kernel to USB driver, and config system. 4, falsh u-boot to USB driver 5, connect to device with UART, hope to stop at u-boot cmdline, and erase emmc. if failed, find other way to erase, maybe Amlogic flash tool. 6, instert USB driver, and reboot device potaintial issues: can't find UART port on mainboard VIM2 mainline Uboot can't boot M16S device does not support boot from USB.
