Greetings
Our board has an AllWinner H5 with SPI flash and eMMC. Since SPI flash support for 'saveenv' is not currently mainline, I thought I'd simply use one of the eMMC boot blocks to persist the environment. However I keep running into image size problems [1]
Not being a U-Boot ninja, the defconfig [2] is about as minimal as I believe I can make it. (Network support is required for TFTP/NFS operations) Does the panel have any suggestions for getting the desired configuration built?

Hey Jerry,
Take a look at the final defconfig once you've run 'make yourboard_defconfig' in order to see if there is anything specific you disable. Your current defconfig is very minimal but a lot of things will be turned on by default and you should look at specifically switching them off in order to reduce the size.
Cheers, Jack.
