DM368 leopardboard

There are various ways of doing it, some are described in the user's guide for the IPNC - you can use a JTAG interface + Code Composer Studio, you can use TFTP or NFS, use the UART interface (which is slow) or you can boot from an SD card & burn images using U-Boot from there.

If you give more information on what you are trying to do that will help.

Bob,

I want dm368 leopardboard to boot from the nand flash.At present i can flash from the sd card.Then i am unable to do the flash from nand.Can u give me the procedure from kernel and uboot image to load on the nand flash.

I'm a bit confused by what you're flashing from where - what do you flash from the SD card? Are you flashing *to* the NAND?

You need to change the boot mode DIP switches to make the Leopard boot from NAND rather than SD.

Bob,

The senario is  I can boot the uImage(kernel Image), Bootloader Image, File System from the sd card. In this case the dip pin switches are in 010 (0 indicates OFF and 1 indicates ON).   Now i want to boot the bootloader Image and Kernel Image from the nand flash with dip pin switches are in 000, can u suggest me now to boot from nand flash with all make configuration and also step by step procedure to boot from nand flash. I was studied many forums and also many guides but i can't understand.

Assuming you have the image files and can get into U-Boot from your SD card, the commands described in my 1st post here show the process of burning everything to the NAND on a Leopardboard DM368.

Bob,

 The issue is i need procedure to do nand flash from the serial port of the host to the target board of dm368 leopardboard. I need step by step procedure to do that.

Does this help at all:

Bob,

 If i turn on the DM368 board UImage and U_boot.bin will be loaded from the sd card(because DIP switches are placed as 010), these UImage and U_boot.bin files in sd card should be write into  the nand (nand flash). what are the steps do i follow

Assuming you have the UBL (ubl_432arm_340ddr_ipnc_dm368.bin) and U-Boot (u-boot-1.3.4-dm368_ipnc.bin) on your SD card, this should be the right thing for the IPNC:

fatload mmc 0 0x80700000 ubl_432arm_340ddr_ipnc_dm368.bin
nand erase 0x20000 0x20000
nand write.ubl 0x80700000 0x20000 0x20000

fatload mmc 0 0x80700000 u-boot-1.3.4-dm368_ipnc.bin
nand erase 0x320000 0x60000
nand write.ubl 0x80700000 0x320000 0x60000

fatload mmc 0 0x80700000 kernel.uImage
nand erase 0x500000 0x400000
nand write 0x80700000 0x500000 0x400000

fatload mmc 0 0x80700000 fsimage.uImage
nand erase 0x900000 0x2000000
nand write 0x80700000 0x900000 0x2000000

Although, as my thread link shows, I'm not having total success with UBL + U-boot at the moment!
