Ake Posted December 21, 2016 Share Posted December 21, 2016 Hi. I have Cubieboard 1 with Armbian Jessie installed on NAND. I've tried to disable output during boot as described here: https://docs.armbian.com/User-Guide_Fine-Tuning/#how-to-toggle-boot-output, but there are no existing boot.cmd and boot.scr in boot partition. I've found out that uEnv.txt have same purpose but it seems that editing this file doesn't affects arguments, /proc/cmdline remains the same.

Igor Posted December 21, 2016 Share Posted December 21, 2016 NAND installation uses old stock uboot which require special treat. Check/adjust "extraargs" within your uEnv.txt file. Link to comment Share on other sites More sharing options...
Ake Posted December 21, 2016 Author Share Posted December 21, 2016 /boot/uEnv.txt: console=tty1 root=/dev/nand2 rootwait extraargs="console=tty1 hdmi.audio=EDID:0 disp.screen0_output_mode=EDID:0 consoleblank=0 loglevel=1 sunxi_ve_mem_reserve=128" dmesg: Kernel command line: console=ttyS0,115200 root=/dev/nand2 rootwait loglevel=8 panic=10 console=tty1 hdmi.audio=EDID:0 disp.screen0_output_mode=EDID:0 consoleblank=0 loglevel=1 Does uEnv.txt require any actions other than editing?

Ake Posted December 22, 2016 Author Share Posted December 22, 2016 Problem is solved. My mistake was adjusting uEnv.txt located in first partition (/dev/nanda) which mounts to /boot. In fact, actual uEnv.txt located in /boot directory of second (root) partiton (/dev/nandb). I've booted from SD, edited it and now everything works properly. 1 Link to comment Share on other sites More sharing options...
Igor Posted December 22, 2016 Share Posted December 22, 2016 I hope one day we will move nand uboot to recent uboot where those settings are done better. Wrote on mobile phone Link to comment Share on other sites More sharing options...
