Part Number: AM3354

Hi,

My customer is evaluating  AM3354 for Oven. they check with us about the startup time, need to less than 3 second,  is this possible to meet this through OS optimization.  also I want to know is there a close ref design for Oven based on TI processor?

    Hi,

    For startup time, which SDK are you using - Linux or RTOS?

    As for oven reference design, I don't think we have something so specific. We have schematics for our EVM boards, links are available here: www.ti.com/.../design-development.html

    Biser,

    They are evaluating our device,  Is there a specific data about the startup time for both Linux and RTOS? I can feedback to my customer to see if can meet their requirement.

    Hello,

    Can you please get more specific details about what the goal of startup time would be? Turn on a GPIO? Display a picture to a LCD? Send an ethernet packet?

    This will help us isolate what can be done.

    Thank you.

    My first post have declaimed their  target startup time is less than 3 second. It is for oven, so should have a LCD and so far as I know, they are familiar with QT and plan to use QT for GUI.  Should have WiFi,  No ethernet . please suggest if 3S is possible for both Linux and RTOS. a rough estimate is OK, honestly, I don't have any experience on processor, just help my customer to check. thanks.

    Hello,

    Is this a cold boot startup requirement? Meaning, from the time the device is powered on for the first time until something happens. Or, can this be from a power suspend state, like suspend to RAM?

    What is their bar for the device being on? Being able to push a button on the touchscreen? Or, just see an image. 

    This is all very customizable depending on the real needs of the system. Our published boot time to a minimal shell is just over 5 sec. I would think that this can be tuned to a specific system and goal to meet a timing of < 3 secs. If they want to use QT, I would focus on Linux.

    I hope this is helpful to you.
