I’m running Gentoo with a. rk3328-cc and am wondering if its possible to get the serial UART working with the OS once it boots. Since its not the libre provided debian-like image, I cant use ldto.
Does the libretech-flash-tool load a DTB with the uart fully enabled? dmesg isnt showing any serial devices when I boot. I’m using the latest libre kernel from the git repo + a full initramfs. OS runs just fine, but I lose UART when uboot hands off to EFI. I’ve tried feeding variations of console=ttySx,1500000 to my kernel command line parameters, no luck so far. Works fine with distros from the libretech website and armbian though.. Figure its a config thing on my end but I cant figure out what.
