TDA2HV: Linux and RTOS requirements and limitations

Part Number: TDA2HV
Other Parts Discussed in Thread: TDA2

Hello,

We are analysing the Linux and RTOS operative system.

  • What minimun memory (Flash, RAM) requirements we have for each Operative System?
  • What is the minimun time for starting up for each operative system (fast boot for RTOS is 500ms, right? Is fast boot available for Linux)?
  • Can you rate the required work for porting the project?
    • (TDA2px)RTOS -> (TDA2px)Linux
    • (TDA2px)Linux-> (TDA2px)RTOS
    • (TDA2px)RTOS -> (TDA4)OpenVX
    • (TDA2px)Linux-> (TDA4)OpenVX.

Best regards,

Andrés

  • Hi,

    Generally, we have 2GB RAM for all TDA2xx device family soc & 1GB is enough to boot both Linux & RTOS OS, Please refer to the TRM to know the flash memory.

    RTOS Fast boot is available only for the TDA3xx  platform & Linux Fast boot is supported only in TDA2xx platform. Refer to the below wiki page to know about the fast boot in Linux.

    Refer to the TDA3xx user-guide to run the fast boot use-case on RTOS

    file:///C:/PROCESSOR_SDK_VISION_03_08_00_00/vision_sdk/docs/UserGuides/VisionSDK_UserGuide_TDA3xx.pdf

    Run the fast boot use-case according to user-guide instructions to know the time  taken by the RTOS for fast boot

    For porting 

    • (TDA2px)RTOS -> (TDA2px)Linux
    • (TDA2px)Linux-> (TDA2px)RTOS

    Can you add more details on what you are trying to port from RTOS to Linux & Linux to RTOS?

    Are you trying to port the vision SDK use-case from RTOS to Linux & vice versa?

    For porting

    • (TDA2px)RTOS -> (TDA4)OpenVX
    • (TDA2px)Linux-> (TDA4)OpenVX.

    Can you add more details? what you are trying port from TDA2px RTOS to TDA4 & TDA2px Linux to TDA4?

    Thanks

  • Hello Gaviraju,

    So, the minimun RAM memory needed would be 1GB for both cases, and the Operative System Selection does not affect the RAM size selection, right? Would be possible a smaller RAM than 1GB for some cases?

    We would like to fit the RAM memory size for reducing the BOM cost for our project, Can you support in that way?

    Only for confirm, the fast boot is only available from Linux for TDA2HV and TDA2px, right?

    Regarding to porting, we would like to know the possibilities for porting some AlgorithmLink_Plugins we have and the few Usecases from RTOS -> Linux and from Linux -> RTOS. For the future task, we are managing the possibility of migrate to TDA4x with OpenVX operative system and we would like to know what is the easier way from TDA2xx RTOS or TDA2xx Linux.

    Best regards,

    Andrés

     

  • Hi,

    Please ask the question related to RAM, Flash, any resource in this thread : 

    The Linux fast boot is supported in all TDA2xx families of SOC but we tested only in TDA2Ex, TDA2Px, TDA2xx platforms.

    If you are familiar with the vision SDK framework then it's a 2 weeks effort to port the algorithm plugin from RTOS to Linux & vice versa.

    I'm not familiar with the OpenVX framework, so no idea about porting from TDA2px to TDA4. I will check with the team & let you know.

    Thanks

  • Hi,

    Please go through the below thread to know about the transition from tda2 - tda4
