Hey Yassin,

I'm affraid. The strange thing that seems very related here is that when 
writing a file onto the flash, it fails and succeeds alternating. It 
never fails or succeeds twice in a row! And this on any board and any 
partition.

I don't know if you only pasted half your command sequence, but it
seems you are writing twice on the same memory region without erasing it,
and this is prohibited on NAND devices.

Try with:

# flash_erase /dev/mtd0 && nandwrite -p /dev/mtd0 u-boot-sunxi-with-spl.bin

Best Regards,

Boris
