RTOS/AM3356: Program jump into do_AngelSWI() after load

Andy Zhou(Zhou Hong Kun)

Part Number: AM3356
Other Parts Discussed in Thread: SYSBIOS

Tool/software: TI-RTOS

I ported the PROFINET Demo to my own AM3356 board.I modified the GEL file and used my repository(DDR size and frequency is different).So "I2C_Example_icev2AM335x_armExampleProject" is OK on my board.

And the momory allocation fails.I don't know if it is caused by the same problem. By the way, DMTimer4 is enabled in GEL file.

Please give me some thought !!

Andy,

Did you update BIOS.cpuFreq.lo = 600000000; in cfg file to align with your board?

Also you can try to uncheck 'Run to symbol main on a program load or restart' in debug configuration, and step from _c_int00 to find out more details around the do_AngelSWI().

Garrett

Hi Garrett,

Thanks again for your reply !

"BIOS.cpuFreq.lo = 600000000" I didn't modify it.

According to your method, I have located the place where the error occurred.

deltaTs=1396, deltaCnt=134, freqRatio=25.

D:\ti\bios_6_52_00_12\packages\ti\sysbios\timers\dmtimer\Timer.c Void Timer_checkFreq(Timer_Object *obj)

This error should be related to the timer frequency.

Could you help me make further analysis ?

Best Regards,

Andy Zhou

Andy,

You may check if the actual timer frequency is 24MHz from the GEL file menu/function (GetInputClockFrequency) with your CPU clock on your board.

By default, .cfg configures DM Timer 4 to 24MHz.
var Timer = xdc.useModule('ti.sysbios.timers.dmtimer.Timer');
Timer.intFreqs[2] = {hi: 0, lo: 24000000}
Clock.timerId = 2;

see
