Rajesh, Tftpboot the kernel image to target memory. Should work by just typing 'tftp 0x86000000' on u-boot command line (assuming you set the bootfile, serverip and ipaddr (ststic) variable).
Or, if you using dhcp, just type 'dhcp'. Then write the kernel image from external memory to nand as nandwrite <source> <destination> <size> In your case 'nandwrite 0x86000000 <destination> <uImage file size>' About the filesystem, read the last topic on http://wiki.davincidsp.com/index.php?title=Filesystem_in_NOR_or_NAND Let me know if you need further help, Cheers, Niko -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of rajesh Sent: Thursday, May 22, 2008 1:19 PM To: davinci-linux-open-source@linux.davincidsp.com Subject: Mounting kernel image and jffs2 file system into NAND flash on HDEVM Hi I am trying to boot the DVEVM(TMS320DM6446) from the NAND flash, followed the steps from SPRAAA0(TI) i have loaded the bootloader into the NAND flash and the board is booting up Now i have to load the kernel image and filesystem into the NAND flash I have created the four partitions in the NAND dev: size erasesize name mtd0: 00040000 00004000 "bootloader" mtd1: 00020000 00004000 "params" mtd2: 00400000 00004000 "kernel" mtd3: 03ba0000 00004000 "filesystem" Can anyone explain me how to load the kernel image and jffs2 filesystem into NAND flash.
