Hi,
For the NOR device, I built the JFFS2 image via the following command:
mkfs.jffs2 -d [root_folder] -o rootfs_image.jffs2 -e 0x1
The last part (-e 0x1) is the erase sector size of the flash device.
You can get mkfs.jffs2 utility from MTD utils at
Based on the VISA's rule ,
it's the single input and single output format.
It's just like:
retVal = fxns-process(alg, inBuf, outBuf,inArgs,
outArgs);
But , I would like to do the process for the current
frame and its prior one.
In other words , it's the 2 input and 1 output
algorithm.
How do i
Hello, davinci-linux-open-source
What tools can convert *.264 to *.mp4, I try to use yamb2.0, but the converted
file only can play on pc. The demuxed frame will be reject when using TI h264
decoder on dvevm.
And I found that ervery frame of the converted file( .mp4 ) is less than the
original
Hi Daniel,
Link is up. I peeked at UBL source code and it seems that it has the
soft reset fix integrated. I haven't tested it yet though.

Hi Andy,
You can load u-boot to your board via JTAG. You'd need a JTAG and a
working GEL file for your board which you probably already have.
Code Composer Studio can load elf files, so assuming that your DDR is
initialized correctly (by the GEL file), you can load a compiled u-boot
Hi Kevin,
I tried to compile and use the davinci_vpfe as a module, but on 'rmmod
davinci-vpfe', I got a severe memory error:
/ $ rmmod davinci-vpfe
Bad page state in process 'rmmod'

Trying to fix it up, but a reboot is needed
Andy,
I wrote the DVFlasher host application and the UBL that is associated
with it. The UBL is written to support CFI compliant Flash devices that
adhere to either the AMD or Intel command set. I have personally tested
with both types of chips, as the newest DVEVMs come with Intel
Not exactly sure what you're trying to do... but I'll state some thoughts.
1. The inBufs and outBufs arguments to process() are an array of buffers -
up to XDM_MAX_IO_BUFFERS (16). So, if you own the application, and the codec,
you can utilize the existing VISA APIs to pass multiple
Ivan,
Yes, the soft-reset fix is included, based on a suggested patch from
Steve Yeh, to initialize all power domains to known states (the key is
the P1394 code copied from U-boot platform.s since this addresses a Si
bug regarding the watchdog timer). Note this change turns on all power
Ivan,
Sorry I may have mis-attributed the suggested code patches to Steve Yeh,
so I'd like to thank you (as well as Steve) for your help in identifying
and suggesting fixes for the soft-reset issue. Any future bugs/patches
that you find/create, we'd grateful if you report them so we can
Hi Daniel, thank you for this comment. About power drain, I know --
actually I submitted the turn-on-all-power-domains patch, while Steve
sent something more minimalistic. Have you checked it?

Cool. I see that you have checked it :) I'm also happy that I helped :))
By the way, I sent to Roger my comments about dvflasher_1_11. It
received only limited testing from me though... Only EVM, booting from
NAND flash. Tomorrow I will test it with our custom boards which btw
have
Andy,
At one point I got that patchset working on 1.10, but I don't recall if
it will work directly in it's current state on 1.10. The tweaks should
be minor for 1.10, and they'll be mainly in the build environment.

Thanks Daniel, I will definitely try your DVFlasher; I just hope the custom
board boots up without problems to begin with ;)

Ivan,
If I'm not mistaken, both fixes were integrated in one form or another.
There is a new function called PSCInit() in dm644x.c, which is now
called at the beginning of the main() function.

Kevin,
I follow your patches and got cmemk.ko to build fine. However, for
dsplinkk.ko, I get an undefined
reference to sys_lseek:
make[2]: Entering directory
`/opt/dvevm_1_10/dsplink_1_30_08_02/packages/dsplink/gpp/src/pmgr'
echo Generating dsplinkk.o...

Yes, DSPlink needs to be fixed for newer kernels where sys_lseek is not
exported to modules.
In the mean time, I have patched my kernel with the attached patch to
export the symbol.

Can any body help me? or tell me what is the point? TI h264 decoder or file
