hi! I update kernel for cubie a10, bud do not know how tu update boot loader. As i know boot loader used uboot. In 1st part of microsd i have files
drwxr-xr-x 3 root root 1024 Jun 18 2015 .
drwxr-xr-x 5 root root 4096 Jun 12 2014 ..
-rw-r--r-- 1 root root 12288 Jun 18 2015 .uEnv.txt.swp
drwx------ 2 root root 12288 Nov 17 2014 lost+found
-rw-r--r-- 1 root root 44240 Nov 17 2014 script.bin
-rw-r--r-- 1 root root 215 Jun 18 2015 uEnv.txt
-rw-r--r-- 1 root root 6544616 Nov 17 2014 uImage
As i understand i need change uImage file. Ok. I goint in /boot And
export VERSION=4.3.3
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e
0x00008000 -n $VERSION -d ./vmlinuz-$VERSION uImage-$VERSION-armv7hl-tegra
Replace file uImage but cubie is not boot
