I am already have read topics carefully:
But this is not resolved my problem
I have board with BF533. I already have own U-Boot in FLASH. SD card successfully connected and contents uImage-ram (with <Initial RAM filesystem and RAM disk (initramfs/initrd) support>) and uImage-sd (without ...) and rootfs from buildroot/output/target. SD file system is ext2. I successfully load uImage-ram , but can not load uImage-sd. More precisely - kernel is loaded, but can not mount root filesystem from SD. Terminal screen is attached. What I do wrong?
