Booting UClinux

Hi!

I'm trying to boot an uClinux from NAND Flash on a M5329EVB. I copy the uImage in NAND FLash using the nandwrite aplicattion on a kernel loaded in RAM.

When I restart u-boot i try to boot from nand (nbood 0x40020000 0 0) uncompressing the image on RAM. Kernels starts to boot but stops at:

Loading from NAND 16MiB 3,3V 8-bit, offset 0x0
   Image Name:   Linux Kernel Image
   Created:      2008-12-09   9:35:12 UTC
   Image Type:   M68K Linux Kernel Image (gzip compressed)
   Data Size:    1600436 Bytes = 1.5 MB
   Load Address: 40020000
   Entry Point: 40020000

(STOP)

and then u-boot takes control again?

Any one knows what is happening on this M5329EVB board?

Thanks

Check out FAQ-28617 which has some tips on moving the rootfile system to NAND memory for a similar board (5373EVB). It may give you enough information to sort out the problem. HTH.

Thanks, but the problem is not mounting a JFFS2 system in my NAND flash.

I would like to get to partitions in flash one for the kernel and other for the filesistem. Any one knows the clue to part it? I'm using u-boot-2008.10 but i can't activate the mtdparts command
