still didn't manage to get boot messages on LCD.
- kernel config has CONFIG_FRAMEBUFFER_CONSOLE and CONFIG_FRAMEBUFFER_DETECT_PRIMARY
- tried uEnv.txt with different console arguments
- tty, tty0, tty1, tty2, ttyO0, ttyO1, ttyO2, ttySA0, fb, fb0, vcs, vcs1, vcsa, vcsa1
- same devices with /dev prepended to the names
- the kernel log shows the updated console message, such as "Jun 26 00:11:59 am335x-evm user.notice kernel: [ 0.000000] Kernel command line: console=ttySA0,115200n8 root=/dev/mmcblk0p2 mem=128M rootwait"
- only for ttyO0, the serial terminal displays the boot messages. for all the others, kernel booting messages are not visible.
When kernel boot starts, the LCD shows the penguin, but no more messages. displaying the kernel boot messages on LCD, and then a login screen on LCD should be possible, but what am I missing? is there a documentation for this somewhere?
thanks for all your answers.
