ILTiming on Windows Embedded Compact 7

Other Parts Discussed in Thread: OMAP3530

Hi,

I would like to measure the ISR and IST interrupt delays on Windows Embedded Compact 7. I found that ILTiming tool in Platform Builder can be used for interrupt delay measurement on earlier version of Windows Embedded.(ex. CE 6.0, CE 5.0) Is this tool also enabled for Compact 7? If not, which tool can I use to measure ISR and IST delays? I'm using TMDS3530EVM as a target board.

    That's an interesting question but I don't think anyone at TI has looked at that. To my knowledge we don't even have an official Win Compact 7 BSP (although there are regular questions here on this...).

    Anyhow the ILTiming tools are part of the platform builder as you said and therefor something coming from Microsoft. So I suggest to ask them. We wouldn't mind some feedback on that as MS is always claiming to fully support our customers. Worst case you have to take the sources from the earlier MS releases and compile on the new one.

    Regards.

    ILTiming tool is available in WinCE7. But as Frank mentioned TI has has not run it on the Omap3530 EVM. If you face any issue running it I recommend that you contact MS first.

    Frank: Just wanted to clarify that Sho Masuda is referring to (using) the Omap3530 BSP that is one of the several sample BSPs that are part of the WinCE 7 release (available to Microsoft ADP/JDP partners).

    Hi Frank and Jatin,

    Thank you for your reply.

    I understand you haven't run ILTiming tool on the Omap3530 EVM. Actually I tried to run this tool several times, but I didn't confirm it ran correctly. I will study again to know how to use this tool and contact MS if I face any trouble.

    Regards.

    Hi, Frank and Jatin

    Let me confirm one thing: Is ILTiming Tool available for OMAP3530 EVM BSP (for CE 6.0)? If so, would you tell me how to run this tool correctly and get appropriate ISR and IST latency results. The reason why I ask you this question is... I think whether this tool runs correctly or not depends on both BSP and OS. (For example... since there is no unused timer available for ILTiming in this platform, this tool is not available)

    I tried running this tool on CE 6.0 R3 using VS2005, but every time this test fails with "Wait for interrupt failed or timed out.". This failure is caused by not being set from kernel an event object that is associated with SYSINTR_TIMING (Interrupt ID). ILTiming.exe waits for 30 seconds at WaitForSingleObject(hEvent, 30000) function, then it ends with WAIT_TIMEOUT. This means that not a single timer interrupt occurs within 30 seconds.

    The version of BSP for Windows Embedded CE 6.0 that I use is 6.14.01. I set ENABLE_OAL_ILTIMING to 1 in Environment variables property before running sysgen process.

    Here is a part of output from PB:
