Hi Chen-Yu,
I made a following steps:
1. sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8
2. Create two partition boot(fat16 - start from offset 10Mbytes) and
root(ext4 - rest after boot)
3. Copy boot.cmd to main directory of boot partition with following content
setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 rootwait panic=10
load mmc 0:1 0x43000000 ${fdtfile} || load mmc 0:1 0x43000000 boot/${fdtfile}
load mmc 0:1 0x42000000 uImage || load mmc 0:1 0x42000000 boot/uImage
bootm 0x42000000 - 0x43000000
4.Copy to boot partition uImage and sun8i-r16-bananapi-m2m.dtb in root folder
directory
5. Copy to ext4 all rootfs files using tar -xzcf etc...
6. Make sync to write everything on SD Card
After above operation I just push sdcard to board slot, serial port to UART0
and power on. Untortunatly nothing happen, Uart silent, Led not bliking. What
is wrong? u-boot spl is wrong?
