Flash Bootload on STM32 from Orange Pi Zero UART0?
gungsukma replied to ZeroWalker's topic in Allwinner H2 & H3
Because UART0 is already used as debug, as you guess. Why not use UART1 /dev/ttyS1 (Pin #8 = TX, Pin #10 = RX)? (I use mainline kernel) mkdir /sys/kernel/config/device-tree/overlays/uart1 cat /boot/dtb/overlay/sun8i-h3-uart1.dtbo > /sys/kernel/config/device-tree/overlays/uart1/dtbo reboot -
Orange Pi Zero 2+ H3, start with USB OTG in dual mode

For Windows, open "Device Manager" There will be item "Gadget Serial v2.4" Get the driver https://www.kernel.org/doc/Documentation/usb/linux-cdc-acm.inf Then just use Putty -
You can power on/off the LED of the LCD using digital pins, not the power pins. May need resistor.

Instead of controlling LCD ILI9341 with the Orange Pi as in the video, I'm thinking of using ILI9341 as the Orange Pi Zero terminal display. But then I'll may end up got very tiny unreadable font. Can it be done directly, or I will need Arduino to read the Orange Pi serial console and drive the LCD?
