Q1,Is there any advises about this problem?

Q2, what means about the error on omap_i2c1?  

Is it the error message about VPSS? BTW, we didn't use any Encode/decode chip such as TVP7002 on our board.

    Hi Lei,

         Actually the problem is the initial Assert messages, not the i2c. you might not get good support with this post, as the EZSDK stopped supporting C6Run in later releases. & the one you are referring old release. But i hope below info will guide you in this.

         With this EZSDK release there is a known issue that CodecEngine (c6run is based on CE) and OMX can not run concurrently, & you will see the above behavior.

         Below steps would ensure to run them concurrently. You might probably need to move latest version of EZSDK at http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/latest/index_FDS.html before doing this.

         1. Ensure that C6Run memory allocation is as per the EZSDK memory map (OMX is already as per this memory map, EZSDK memory map at http://processors.wiki.ti.com/index.php/EZSDK_Memory_Map.

         2. Update the C6Run DSP side cfg file with the below changes

              2.1 C6Run DSP side CFG file any reference to Shared Region 1 must be modified to use Shared region 0 itself, As Shared region1 is used by OMX.

              2.2 The above change must be done at Linux side also

         3. Rebuild C6Run and execute.

         Even with above change we have noticed that the shutdown (Startup is fine) of one of the above app fails, fix for that will be provided in next EZSDK release.

    Thanks & Regards

    Hi Velan,

    Thank you for you reply.

    We found that a memory leak bug was fixed in UIA 1.01.01.14,

    (SDOCM00093458 Memory leak in UIA) 

    Should I update UIA to latest release in EZSDK 5.04?

    Regards,

    Lei

    Do you mean config.mak file under C6run install folder?

    Here is the config.mak file in C6run 0.98.03.03

    PLATFORM=TI816x
    C6RUN_INSTALL_DIR=/media/ezsdk/ti-ezsdk_dm816x-evm_5_04_00_11/component-sources/C6Run_0_98_03_03

    DSP_REGION_CMEM_SIZE=0x02000000
    DSP_REGION_CODE_SIZE=0x01500000

    I didn't find the config about the Share Region you said,

    can you tell me which file should I make those changes?

    And I found there are 3 Share Regions in EZSDK Memory Map page.

    Can you tell me which one is the Share Region 0?

    Thank you .

    Hi Velan,

    this thread is near to  the subject of this yet unanswered thread. Your answer spends much hope, but for me it is somewhat too unconcretely. The memory map settings are spread out over so much *.cfg, *.bld, *.xs configuration files... although a lot of that probably just has to be obverloaded somehow, it is not even simple to get an overview over all that. (In my case I fight to get a CodecEngine-based application (ARM/DSP) running concurrently to an OMX application (ARM/HDVPIC - H.264 compression), we already use EZSDK 5.04.00.11. 

    Velan said:

    That lets me hope, but: when will that release be available? And, much more, will then possibly the whole problem be solved, and running CodecEngine concurrently with OMX applications then is no longer a problem? And currently we care around problems which then no longer will exist?

    Last not least I want to mention this thread:

    How to use codec engine or C6Run component together with omx component in ezsdk5.03?

    Maybe it will help you, Lei, we are currently analyzing the hints from there, but not yet solved the problem. If I know more, I'll post it here.

    Kind regards,
    Joern.

    Hi Joern,

    Thank you very much for your help.

    Joern said:

    Do you mean that the C6Run/CodecEngine cannot work concurrently with OMX application because of some resouce (Share Region or something) conflict in EZSDK 5.03 or 5.04.

    And to fix this I should modify the config files in C6Run/CodecEngine as the page below you mentioned.

    In our program, we just use OMX to capture from cameras,

    so if  we change OMX to V4L2 , that problem will be not exsit, am I right?

    Yes, all information puzzle pieces I've seen until now lead me to that assumption. Most concrete concerning that is the mentioned thread.

    Lei Wong said:

    I am not sure about that. But I'd assume that also the Video4Linux driver will bring some memory map settings, which might conflict as well. However, we're using OMX not only for capturing (in the end via an V4L driver, too), but also to control an H.264 encoder. So in each case we need to know about the exact reason for the problem. The mentioned thread gave us a concrete hint, but for some reason I've found that thread only in the very last few days, so yet we haven't that tried out completely. If we should find to any progress concerning that, then of course I'll post it here.

    But until then it was very kind if some of the most helpful TI people concerning EZSDK/CodecEngine/Syslink, like Janet, Rahul, Ramsey or Chris  (sorry if I forgot somebody, but these four I've always in my mind) might give some hints.

    Kind regards,
    Joern.

    Lei,

    The people you mention are all on the SysLink team. We provide the low level IPC implementation. Other products such as C6Run, OMX, V4L2, all build on top of SysLink. Each of these products have their own resource requirements (e.g. memory map, shared regions, etc). These products are typically developed for specific markets (audio, video, medical) and are not designed with for foresight needed to integrate them into one application.

    Unfortunately, there is little advice we can offer regarding the integration of these products. We will try to address specific questions, but our expertise is focused on SysLink, not these products.

    As I transplant C6RUN 0.98.0.0 to ezsdk 5.04, the program may stop after about 15 minutes without any massage, and sometimes it can work more than 2 hours without any error, though I didn't change any share memory settings in the source code.

    I use fprintf to print out debug messages from DSP, and I found that the program often stopped before the DSP function return or before the DSP function start.

    Do you have any idea about this problem?

    Lei
