Hi Sami,
Thanks for the information.
How should I configure the uboot so I can boot from the 1.45 GB partition ?
Thanks

Hello Kumar,
On the DM355 EVM the NAND flash is split into different partitions.
/dev/mtdblock3 is 512MB and /dev/mtdblock4 is 1.45GB. The remaining
Hi,everyone.
I encounter some difficult when i boot my linux on a NFS.
The u-boot parameters:
bootargs=console=ttyS0,115200n8 noinitrd rw ip=192.168.0.244 root=/dev/nfs
nfsroot=192.168.0.243:/home/gabriele/workdir/filesys,nolock mem=120M
With MV LSP 1.20 it worked fine, but with git version

actually it can be less (you can transmit while you encode and encode while
you get video) but it is VEEERY expensive. You have to buy heavy 3rd
party video codecs.
What is your problem? Maybe we can help you

Hi,
Thats what I do now, I have a ping-pong buffering scheme.
Jon, thanks for the information. Any idea what the best systems offer.
Coz we want to beat that !

Hi all,
I am having a MPC852T board in which I am having u-boot in my NOR Flash and
uImage and jffs2 in NAND Flash.
If any one or more Bad block(s) in the uImage loactaions (0x0 to 0x20) in
the NAND Flash, resulting the Bad Magic Number error during Kernel booting. It
seems uImage needs
You can also look at /proc/partitions or /proc/mtd to find out more
about the NAND paritions on your system.

Gabriele,
I don't see in your output where the IP-Config is running to setup your
network. Are you sure that with the Git kernel you have enabled the
network driver to be built into the kernel?
In my kernel I see the ti_davinci_emac device being registered but I
don't see that in your
Hi Sedar,
Yes, you can download via RS232 to uboot using xmodem protocol,
however is a bit slow.
We worked with TI in a USB DFU implementation for u-boot in DM355 that
could be more useful for your proposes (and is even faster than
network). Our upcoming revision of our free DM355 SDK
So can the DDR memory be changed to support the bandwidth? Does anyone have
any suggestion. What I am trying to do is have 4 video source and at any
one time recoded 1 channel to disk while displaying another on the monitor
and if possible also be able to display a quad view of all 4 channels on

ddr2 theorical bandwidth = 297M * 4 * 32bit/8 = 4752MBytes/s
because of delay ,bandwidth = 4752*0.4 = 1900MBytes/s
4 channels D1(720x480) data = 720 * 480 * 2 * 30frames/s * 4 channels =
82944000Mbytes/s = 81MBytes
the data save to DDR2 and load to cpu to process,meanwhile,send to OSD to

I am in the process of splitting this patch based on Kevin's recommendation.
Planning to post it by this week but his recommendation was to post it in the
linux-omap list and I might probably post it there. I think the same shall be

I want to output from DM355 to my RGB666 LCD but it couldn't work properly
where the FIELD pin suppose to be a R2 signal. I got a low voltage (about
+-500mv) pulse train on this FIELD pin. I seems to me its still a PWM output
