DVTB on BeagleBoard.

Hi everyone,

I installed TI's dvsdk on my host. Reconfigured the following memory
allocations in the decode.tcf/encode.tcf in dvsdk_install_dir/
omap3530_combos/pkgs/ti/sdo/servers/decode, encode/:
DDRALGHEAP,DDR2,DSPLINKMEM,RESET_VECTOR as it seems the previous
settings(0x86800000-0x89700000) override the kernel memory
(0x80000000-0x88000000).

I built the combos_dir and then built /dvsdk_install_dir/
dvtb_install_dir, and got dvtb-d/r excutables.

I load the excuables and loadmodules.sh(reconfigure the cmemk.ko's
phys_start and end, due to the same reason) into beagleboard, 1. load
the three modules sucessfully, 2. open dvtb-d/r, 3. set the h264encode
params(setp params) and activate the h264 encode process(func ).

The result looks no good:

"failed to open engine", error=3 means "cannot load DSP"

I don't know what exactly this error means, and please anyone tell me
why it doesn't work, and how should I fix it??

Thanks in advance.

?Im sorry, What do you mean??

This is setp and func:

func videnc1 -s test.yuv -t h264e.264

This is the command result:

Thanks， the results here.

The file encodeCombo.x64P, which contains the DSP code, needs to be in the same directory as the DVTB executable, so it can be downloaded to the C64+ processor.

Thanks, I copied the x64p file to dvtb excutable directory, and run,
This time it get something new, i hope you spend some time help me
analyse:

there's still error in engine-open(encode), and I might need to
configure the params of dsplinkk.ko, cmemk.ko, lpm....ko.....?
and after that, the beagleboard pending there, and I can't quit by
typing "z"or"exit", althrough it shows "exiting...."

Please tell me why this error happens?
