Hi guys, I have a problem when I try to load uClinux Kernel with JFFS2 root file system.
I have a BF548 EZKIT Lite board.
First of all, I enabled support for the jFFS2 and mtd-utils package and compiled my uClinux Kernel. I obtained as a result these 2 files : vmImage(1.3MB) AND rootfs.jffs2(4.3MB).
After than, I loaded the rootfs.jffs2 using TFTPBOOT and wrote it to my Flash (size:16MB). Finally I loaded vmImage using TFTP and I modifiyed bootargs.
When I boot my uClinux (using bootm) I obtain the following error :

mtd devices start counting from 0, not 1, and unless i missed something, you only registered two partitions
