If you are using mainline U-boot (and possibly by extension, BPI's mainline U-boot repo), you are supposed to use the u-boot-sunxi-with-spl.bin file. This is a concatenated file composed of the SPL (U-boot's boot0.bin if you will), U-boot proper, and some padding. Write that one to where you would write boot0.bin. This is all documented here: http://linux-sunxi.org/Mainline_U-Boot ChenYu > > I try to make Yocto meta-layer but without working boot section it is > impossible. > > Thanks for any hints. > > Regards > > -- > You received this message because you are subscribed to the Google Groups > "linux-sunxi" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > For more options, visit https://groups.google.com/d/optout. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
