  • [SOLVED] Freertos: Call stack for selected task?

    Hi,

    from available information I gather that selecting a thread in the FreeRTOS task window should make the call stack window display the call stack of the selected task.
    Can you confirm is it so ? Maybe I just cannot handle the UI.
    What I do: make the software stop at breakpoint. I see several tasks and the call stack of the active task. When I select any other tasks in the FreeRTOS window, the call stack remains the same.

    Ozone 3.22b, I tried on Windows and Linux. Freertos plugin is added to project upon Ozone suggestion at project creation.
    Target: cortex-m7

    Thanks in advance

  • Slow FLASH programming with i.MX35 and S29GL01GP

    Hello,
    We have a custom HW equipped with Freescale i.MX35 processor and Spansion S29GL01GP NOR FLASH (1024x128kbyte sectors).
    For erasing and programming the FLASH we wanted to use our J-Link Pro interface.
    We could connect to the target correctly.
    When we tested the sector erase time, we got reasonable results (~87s for erasing 128 sectors).
    But when we wanted to program the FLASH, we experienced very low flashing speed: 474 byte/s.
    We performed speed test (IRAM, 128kbyte) which reported ~181 kbyte/s down and ~188 kbyte/s up speed.
    When we enabled the "Use target RAM" for IRAM and 4 KB, the RAM check timed out.
    After that we changed the RAM size to 1 KB. With this setting the RAM verification passed, but the subsequent erase / program operation timed out.
    Did anybody experienced such a slow flashing speed?
    If yes, did anybody find the reason behind that?
    The "Use target RAM" option seems to be useless.
    Did anybody use it with i.MX35 target?
    Best regards,
