Replies: Re: u-boot make failure: SPL image too big Hi, Glad that the issue is now fixed. Just for your reference, you may refer below for the latest boot method and debug steps: https://rocketboards.org/foswiki/Documentation/BuildingBootloader https://rocketboards.org/foswiki/Documentation/SoCEDS Replies: Re: u-boot make failure: SPL image too big It appears the problem is fixed by doing a "make clean" and running make again.
