I have a custom-built set of binaries and would like to update u-boot on my system. 

Taking a look at the olimage source (olimage/olimage/core/bootloaders/allwinner/a64.py) I see that the sunxi-spl.bin file is written:
dd if={}/sunxi-spl.bin of={} bs=1k seek=8 conv=sync,fsync,notrunc

Followed by building of the u-boot.itb and finally writing it:
dd if={}/u-boot.itb of={} conv=notrunc,fsync bs=1k seek=40

What I'm wondering is whether the u-boot.itb is generic, and not unique to a newly built sunxi-spl.bin, and if so, whether u-boot.itb needs to be rebuilt re-written or can the existing one be left in place?

Thanks in advance for any advice anyone can lend.


Is there a forum that would be better suited for u-boot-olinuxino questions? 


I suppose you could try the U-Boot ML and/or the linux-sunxi ML.
