Hello again,
I took a look into:
1. freebsd manpage for gpart
2. freebsd manpage for mount_msdos
3. source code /usr/src/u-boot-sunxi/fs/fat/fat.c where "Error reading
cluster" exists:
if (get_cluster(mydata, curclust, buffer, (int)actsize)
!= 0) {
printf("Error reading cluster\n");
return -1;
}
Then I've tried different combinations, like:
gpart add -b 1m -s 64m -t fat16 md0
newfs_msdos -F 16 /dev/md0s1
gpart add -b 1m -s 64m -t '\!12' md0
newfs_msdos -F 16 /dev/md0s1
gpart add -b 1m -s 64m -t '\!14' md0
newfs_msdos -F 16 /dev/md0s1
And still getting "Error reading cluster" on kernel file.
I've compared file on SD card and compiled one and they are match (as
diff is not giving any output).
I've also checked fragmentation and kernel file is one piece..
If I replace kernel with kernel.bin, then:

It looks like file is loaded, because output is different and says it's
data.
In file /usr/src/sys/arm/conf/BANANAPI I have additional:
ident BANANAPI
options ROOTDEVNAME=\"ufs:/dev/da0s2\"
options INCLUDE_CONFIG_FILE
options EXT2FS #EXT2 filesystem
but no MMC ? (same as Cubieboard2 config)
# MMC/SD/SDIO card slot support
#device mmc # mmc/sd bus
#device mmcsd # mmc/sd flash cards
Uncommented changes nothing.
file bananapi.dts match cubieboard2.dts except:
< model = "Lemaker BananaPi";
< compatible = "allwinner,a20-bananapi", "allwinner,sun7i-a20";
---
> model = "Cubietech Cubieboard2";
> compatible = "cubietech,a20-cubieboard", "allwinner,sun7i-a20";
Changing boot.cmd from:
fatload mmc 0 0x40200000 kernel; go 0x40200100
to:
fatload mmc 0 0x40200000 kernel
go 0x40200100
Gives nothing..
Cheers,
