hi, I've downloaded the u-boot sources from GitHub ( UDOOboard / U-Boot_Unico ). I compiled the u-boot by using the compile.sh script. The U-boot can compile. But I see my u-boot.bin file is 216kBytes, and the u-boot.bin from the download page is 2.2MB :shock: . Why? If I use my u-boot.bin the I.mx doesn't work. If I use the u-boot.bin from the download page, everything works fine. What do I wrong? Thanks for hints.
