It is a little tricky to flash the filesystem through JTAG, since you have to take care of sparebytes (OOB, ECC) and bad blocks. Also how do you plan to come up with an actual filesystem image (e.g. YAFFS2) ? I do not think mkfs.xxxx utilities are “bad block” aware. There may also be issues with sparebytes.
We first boot the kernel with ramdisk and then populate the filesystem (a tar ball) on NAND using mount and “tar xf” commands.

I want to load ubl-uboot-and file system to nand flash via jtag. I want to speed up our production process . What is the fastest way for Flashing nand flash? Unfortunately there is no empty place on uarts on our dm355 uart0 is using for communicating with a mcu on our board , Uart1 is going to use for communicating for GPS kit, so I have to use Jtag for it.

Just use tftpboot from uboot to download your files into memory and do a nand clean + nand write. ________________________________ From: davinci-linux-open-source-bounces+swoods=pelco....@linux.davincidsp.com [mailto:davinci-linux-open-source-bounces+swoods=pelco....@linux.davincidsp.com] On Behalf Of canibek sagin Sent: Tuesday, December 16, 2008 8:22 AM To: 'Phil Quiney' Cc: [email protected] Subject: Flashing Nand Flash Hi All, I have some empty nand flashes. I want to burn them and add my uImage,uboot,ubl, and File system. I googled and figure out that there is a way for serial port but on my board there is no rs 232. My board only have JTAG. I wonder that , I can write ubl and uboot to empty flashes via xds 510 and CCS 3.3 but what about filesystem? How may I add it to nand flash? On serial production It is very difficult to use serial port and some commands which is described on getting started guide for dm355. I have bought also peedi, for nand flash programming but it is not supporting dm355 I couldn’t use it. I want to burn my new flashes with xds510, Is it possible? - ------------------------------------------------------------------------------ Confidentiality Notice: The information contained in this transmission is legally privileged and confidential, intended only for the use of the individual(s) or entities named above.
