Hi,
Does DVEVM has a Video Out port demo?
Which is that?
What is the DaVinci Video Out port driver file(s)?
Thanks,
Alex

Hello,
Is there a DaVinci SPI driver available for 2.6.10 or "davinci git"
kernel?
If yes, please let me know where can I download it from?
Thanks

I have seen some code for the TSC2101 touchscreen controller / audio codec in
the OMAP git tree.

Ok, I understand now. I don't think that this
You could write a simple UBL (example source is available as part of the
DVFlasher application package) that does as a real PC does, loading and
executing the disk's master boot record (first 512 bytes of the disk).
If a linux bootloader like LILO or GRUB could be ported to the ARM (or

A non-fatal error such as a bit error, or a corrupted header, will make
the demo reject the frame.
Look in xdm.h for the XDM_ErrorBit for a list of extended errors.

It'd be also great if you make the UBL more straightforward to port for
boards with less than 256 MB memory.
For current implementation I had to change:
.ddrram2 starting address in ubl_davinci.lds,
MAX_IMAGE_SIZE in ubl.h and
RAM_END_ADDR in ubl.h
For my memory map (128 mb), I set
Ivan,
Thanks for the suggestions. It's certainly true that the two programs
(the UBL and the host app) can be made more user friendly for porting to
custom boards, as that wasn't the primary goal when I began writing
them. I'm now working on a similar program for the next DaVinci device,
and
Great to hear that you'd be dropping the s-rec format. It's bloats
images quite a bit and makes downloads over the UART more slower than
they should be.
What would be the format you'd use? Have you decided yet?
Can you tell us more about the new application you are developing?
Thanks,
Ivan

Ivan,
If I am able to back port it, it would be simple packets of binary data
with CRC checks. I want to drop the Srec format exactly for the reasons
you mentioned. I can't say more about it right now.

OK, great. And just a little suggestion -- if you are in charge of
choosing the binary image header format (to be stored in NAND, NOR, HDD
or whatever medium), why don't you use uImage?
Several months ago I wrote a nand UBL replacement with uImage support
and code for uImage parsing and crc'in
I'll definitely look into that.
Thanks,

Cool.
Also keep in mind that uImage headers have strings identifying what they
contain + crc + other nice properties.
From u-boot/tools/mkimage:
-A ==> set architecture to 'arch'
-O ==> set operating system to 'os'
-T ==> set image type to 'type'
-C ==> set
I agree. uImage is a good format. To save space for the CRC32 check I
would recommend not using the usual fast table implementation. Even the
time spent by a simple slow bitwise shift/xor will be insignificant
compared to the UART download time. I'm using something like that
myself, and it's pr
Has anyone had success connecting the DaVinci EVK to an LVDS chip/LCD screen
via the onboard video output?

Hi all,
I want to access my HDD in UDMA4 mode (ATA 66). Unfortunately it seems
that with current davinci driver, this isn't possible. Am I wrong?
hdparm tells me that I'm in udma2 and when I try to set udma4, I receive
this message: "ide0: Speed warnings UDMA 3/4/5 is not functional."

Hi DaVinci experts,
Has anyone of you used FIQs with DaVinci? Is this possible with the
current MV codebases (GIT and stable)? If not does anyone has pointers
to what modifications have to be applied? Any kind of examples would be
greatly appreciated!
Please help me. I'm a noob :)
Thanks,
I
> Kevin, how do you get a specific tag (version) of the GIT tree?
If you are using cogito, then you can use the "cg-export" command. For
example, I would:
1). Execute "cg-tag-ls" to display all the tag names
2). Execute "cg-export -r "
Note that cg-export supports .tar, .tar.gz, .tar.bz2 an

Hi Brady
I don’t know why you need hdd file system to boot from HDD!!
I my case, I used a small Nor flash (1MB),
And I initial the davinci HDD interface in u-boot,
Then read the Uimage raw data from HDD to DDR2,
Now It work will!!
And the HDD Initial you could follow the Linux driver!!
I'm using 2.6.20-rc5 . (.git/refs/tags shows v2.6.20-rc5 as last entry).
Are you loading all the necessary modules. For me, usbcore is statically linked
and then after boot I load below modules (in that order)
musb_hdrc.ko
scsi_mod.ko
sd_mod.ko
usb-storage.ko
I tried in evm kernel also _witho
Hi,
I want to enable uart2 (ttyS2) on my davinci board.
how to enable it in the bootloader & kernel.
I have seen davinci pdf supporting more than one uart.
How to make it?

Hi guys,
Iam using davinci board with NOR flash.
I made a five partitions in NOR flash using mtd.
I made kernel & file system in the flash using jffs2.
I faced no problems.
Now i changed to NAND flash.
After changing my bootloader, my davinci board got booted-up with NAND flash
