tsmx Posted July 7, 2020 Posted July 7, 2020 Armbianmonitor: http://ix.io/2r7k Hello. I have an Orange Pi Zero board with Armbian on it. I want to use its serial pins for flashing arduinos. Right now I only have 1x3 serial pins and 1x13 media (?) pins soldered, the 2x13 GPIO doesn't have any pins and I don't have any spare ones to solder (alright, I might have some, but I'm too lazy for that). That means I only have access to UART0 pins which are currently reserved for Linux console. With RPi Zero and Raspbian the same problem was solved by simply removing "console=ttyAMA0,115200" from kernel options. However, Armbian seems to generate kernel options entirely from armbianEnv.txt, making it impossible to manually remove serial console stuff. I tried setting "console=none" or just deleting this line from armbianEnv, but it just sets console to "both" in boot.cmd and nothing changes. Any other options?

Edit /boot/boot.cmd instead to remove the "console=ttyS0,115200" part, and recompile the /boot/boot.scr using "mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr". Make sure /boot/armbianEnv.txt has "console=display" ...
