Greetings,
I am making U-Boot boot my kernel from SD card as fast as possible, hopefully directly from SPL. I found the Falcon mode handy, but there isn't a lot of documents on it, and it seems like I still have to run a special 'spl export' command in regular U-Boot to generate a binary blob. This seems very unpleasant because I do want to build and ship all images on my computer, without the need to 'run a full U-Boot once on the production board on every single firmware upgrade'. Honestly, I am also quite confused why do we need such a command at all, given that I have my kernel and DTB directly accessible from the SD card.
Is there any way to get rid of the need of exporting the blob? I do have my kernel and DTB handy. If it is not possible with U-Boot, are there any other solutions that support loading kernel directly from SPL? My SoC is Allwinner V3s.
Best regards, Yuuta Liang
