Hi,
Most featureful boards, such as the Cubietruck, have been broken since the release 2017.09.
This is due to a size increase of the binary that will trip us across the size we've been using in the u-boot-sunxi-with-spl.bin file.
We would have two ways to work around it. The first one would be to just increase the offset of the environment. However, since it would break all the environments of our users and possibly the custom partition scheme that they would have created, it doesn't really seem like a smart move.
Is that really such a problem? How many people rely on having their custom environment preserved over an update? (That's an honest question)
I see that the environment is hardcoded to 0x88000 in env/Kconfig. Where does this value come from? Why is it this rather arbitrary value?
I believe the real limit should be 1MB - ENV_SIZE. Most sane partitioning tools put the first partition at 1MB, so this leaves the space below that to the bootloader/firmware.
This would put the actual limit at 856 KB for now - that should be enough for everybody ;-) We could even push this further by reducing ENV_SIZE to say 64KB.
At least that would buy us some time to address this issue in a more sustainable way.
Cheers, Andre.
Another one would be to start trimming down a bit our enabled options in order to reduce the size and to gain some extra space for users customisations. I've taken care some of the low hanging fruits, and we should probably take another go at it in the future (and add a size check in the image build somehow?)
