Hi yoni :
Have you solved the problem you post?
I encounter a similar one, and I need your advice, Thanks very much!
I use:
board: DM6446 DVEVM
NAND device: Manufacturer ID: 0xec, Chip ID: 0x36 (K9F1208R0B)
MV Linux:Linux version 2.6.10_mvl401-davinci_evm gcc version 3.4.3

Hi All,
How to convert the other format video file into the mpeg-4 format what can be
decode on DM355?
When I played a mpeg4 file on DM355, I found some green noise existed on the
top/bottom/left/right of the video frame.
And I decoded this mpeg4 file into YUV format using dvtb on

Please check the JFFS2 wiki page. This covers using nandwrite to write
the file system image. Primarily I do not use the -j option when using
the nandwrite command.

Jitendra,
You should be able to find this in the driver data sheet. However, on
the DM6446 there are updated patches in patchset 45 that will
significantly increase the SD performance. I saw write throughput up to
around 7.625MB/sec depending on the SD card being used.
Sincerely,
Chase
Hi,
I am developing a video decoder on DM6446. The decoder internally uses
DMA for data transfer from external Mem to L1SRAM and from L1SRAM to
Ext Memory. I am using 64KB of L1SRAM, out of which 62 KB is for
reserved for L1DHEAP and 2 KB is for use by stack.
I am using codec engine 1.02. xDM
Hi,
i'm attempting to create a Gio driver for our purpose, with DM355 and
dvsdk_1_30_00_40.
While with the oldest kernel i was able to create a working one, now i'm
not stil able, because of changes in the kernel interface.
in particular:
- i don't see /proc/gio/ directory.
- i can't use
We no longer have a provision for proc entries in the latest GPIO
driver. That is the reason you do not see /proc/gio.
In arch/arm/mach-davinci/board-dm355-evm.c, have a look at the
setup_ethernet() function. That will give an example as to how you can
use the gpio driver.
Thanks,
Sandeep

Philip,
Do you have a log without trace enabled? It's easier to see success/failure
with that. In RingIO, the behavior is such that acquire failure is ok (it will
then go and wait for buffer to be available). So the failure in the API doesn't
necessarily mean failure in the test-case.
For
I believe this is defined by the TI codegen and is undocumented(!). The next
release of xDAIS has updated examples where that preprocessor guard is replaced
with:
#ifdef __TI_COMPILER_VERSION__
#endif
The __TI_COMPILER_VERSION__ preprocessor symbol is also defined by the TI
codegen, but it
Hello Everybody!
Now I use the DM355_EVM to design a IPNC product.The EVM board use TPS65021 as
its power chip,and TPS65021 has a I2C configuration interface whose device
address is 0x48.
But I need use this address to access other chips,so I need to konw if I can
cut off the I2C connection
Hi Chase,
Thanks for your response.
I am not able to find patch 45.
Can you pls share with me or provide me the link?
I am using 2 GB SanDisk SD card and 4 GB SDHC card of class 4 and 6.
I am getting same performance results in all above cards.
Can you share with us different flavors of
