I am trying to put a u-boot on the flash memory. I downloaded one named "u-boot.nitrogen6q" it was supposed to be a good one.I found this method to put it in the flash:
mmc dev 1
mmc read 0x10800000 0 800
sf erase 0 0x40000
sf write 0x10800000 0 0x40000
then it should be in the flash, however, it's not and when i reboot the sabrelite, the u-boot didn't lauch and if i put a sd card with android in it, nothing happened.
Is it the method i use which is bad, did i forgot something or is it the u-boot?
If you have a good link to help me to put android on the card, it would be helpful.
