Thank you for your inputs! I can see that both imx-boot binaries begin with the same hex content, the tenth byte whatsoever is 01 in my build and 00 in the build from Variscite. Then from the 23rd byte some more differences and then the same bytes again. Lots of blocks with the same content but still different. Actually I don't know how to interpret that correctly. I don't know about openBMC either but looks interesting, thanks for pointing, I'll have a look. What does that mean, the boot is vendor-locked? The imx-boot image they build can be put onto the sd-card and the board boots. So it must be something within this image or u-boot itself I guess? Or do you mean they put some signature or something in there?
