using sys/bios with msp430f5510, call to Task_sleep(n) hangs tasks, but clock function still running

I have created 2 tasks with the same priority (8) and 1 clock function, all statically defined in cfg.

Task_yield() switches between the 2 tasks as expected, but a Task_sleep(10) call hangs (neither task picks up).  The clock is running per calls to Clock_getTicks().  The clock function keeps going as well.

Here are my versions:

"C:/ti2/xdctools_3_24_05_48/xs" --xdcpath="C:/ti2/bios_6_34_02_18/packages;C:/ti2/ccsv5/ccs_base;" xdc.tools.configuro -o configPkg -t ti.targets.msp430.elf.MSP430X -p ti.platforms.msp430:MSP430F5510 -r release -c "C:/ti2/ccsv5/tools/compiler/msp430_4.1.2" --compileOptions "-g --optimize_with_debug" "../clock.cfg"

Thanks.

    Spencer,

    By “the clock is running per calls to Clock_getTicks()” – does this mean that you are calling Clock_getTicks() from some other thread context and are seeing the tick count incrementing?

    If you set a breakpoint on the symbol “ti_sysbios_knl_Clock_doTick__I” do you see the breakpoint hit repeatedly?

    Also, can you post the text contents of your “clock.cfg” file?

    Thanks,
    Scott

    Scott,

    Turns out it’s a stack space issue.  Increased from 256 to 300 and it works.  I don’t have a working debugger and have been concerned about stack space but hadn't got to measuring it yet.  

    Apparently Task_sleep() vs. Task_yield() pushed me over the top.

    Thanks.

    Spencer,

    OK, good, thanks for reporting back.  

    If at some point you’re able to attach CCS, you can check system and task stack usage via the RTOS Object Viewer (ROV) - see section 6.5.3 in Bios_User_Guide.pdf.
