Any idea? Just forgot to mention, that I was actually booting from MMC (mmc1). The boot sequence is UART0...XIP...MMC0...NAND. If I just mount ubifs partition as rootfs and change some files, I still can perform reboot and boot from MMC again. The issue seems to occur only, if I write to /dev/mtdblock directly. What can affect ROM boot so that it doesn't follow the boot sequence?
