I am using an internally designed bootloader. I am using MX21
development board with intel strata flash. I copy bootloader, kernel
image and flash system to the flash and try to reboot the system. system
hangs although the same sequence is running fine with cram file system.
Of course with different kernel configs.

	Both or either one. I know generally but I was hoping to be directed to
the specific file.

Mapping driver and support for mtd partiion is there. also I am using *
instead of M in the menuconfig
