maxxfi Posted May 5, 2016 Posted May 5, 2016 Hi, is it possible to have the serial/UART on the Olimex LIME2 to work as a serial console on Armbian Jessie (kernel version 4.5.2)? The UART is already working during early boot, but once kernel is loaded it becomes inactive. /boot/boot.cmd contains: setenv bootargs "console=tty1 root=/dev/sda1 rootwait rootfstype=ext4 sunxi_ve_mem_reserve=0 sunxi_g2d_mem_reserve=0 sunxi_no_mali_mem_reserve sunxi_fb_mem_reserve=16 hdmi.audio=EDID:0 disp.screen0_output_mode=1920x1080p60 panic=10 consoleblank=0 enforcing=0 loglevel=1" Thanks
zador.blood.stained Posted May 5, 2016 Posted May 5, 2016 Initial output after start/reboot is from u-boot. To use serial console as main for kernel messages and init progress, change console=tty1 to console=ttyS0,115200 in boot script and recompile it using command at the end of the file.
maxxfi Posted May 6, 2016 Author Posted May 6, 2016 Ah... thanks! So, where is the 'tty1' setting currently sending the console to?
zador.blood.stained Posted May 6, 2016 Posted May 6, 2016 So, where is the 'tty1' setting currently sending the console to? To primary display - HDMI/VGA (for capable boards).
