how to use fatload uEnv.txt & script.bin & kernel uImage

step 1: dpkg -i linux-bananapi-bpi-m3-kernel3\_1.2.8\_armhf.deb

step 2: bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m3/BPI\_M3\_720P.img.gz

step 3: mkdir -p /boot/bananapi/bpi-m3

step 4: cp -a /usr/lib/u-boot/bananapi/bpi-m3/linux /boot/bananapi/bpi-m3

step 5: cd /boot/bananapi/bpi-m3/linux ; vi uEnv.txt (if you want to change)

step 6: reboot

```

how to check output video mode:

```
root@bananapi:~# dmesg | grep DISP

how to boot with SATA rootfs:

```
# vi uEnv.txt
# ref. sys_config.fex, use default script.bin
bootargs=enforcing=1 console=ttyS0,115200 console=tty1 root=/dev/sda2 rootwait init=/init vmalloc=384M ion_cma_list="120m,176m,512m" loglevel=8 bootmenutimeout=10 datadev=sda2

how to boot with USB DISK rootfs:
# vi uEnv.txt
# ref. sys_config.fex, use default script.bin
bootargs=enforcing=1 console=ttyS0,115200 console=tty1 root=/dev/sdb2 rootwait init=/init vmalloc=384M ion_cma_list="120m,176m,512m" loglevel=8 bootmenutimeout=10 datadev=sdb2
```

for berryboot env. use only: bootmenutimeout=XXX datadev=XXX
