BIOS_start() problem

Other Parts Discussed in Thread: CC3200

Hello Everyone,

Environment Information :

OS : Windows 7

LP : CC3200 - Launchxl Rev 3.2

SDK : v 0.5.2

I am new to TI-RTOS. I am using TI RTOS with Simplelink CC3200 MCU. I am experiencing strange behavior with BIOS_start(). It gets hang inside Hwi_asm.sv7M file at following line.

stmfd   sp!, {r4-r11}   ; save r4-r11 while we're at it

Here is the screen capture where my code gets hanges each time.

Kindly help me to overcome this issue..

Regards,

Niral

  • [added Hwi->Detailed to the list below]

    Can you open Tools->ROV and open the following and post pictures of them:

    Task->Detailed

    Hwi->Module

    Hwi->Detailed

    BIOS->Module

    BIOS->Scan for errors...

    Does the TI-RTOS empty project work for you. It's in Project->New CCS Project...

  • Hello ToddMullanix ,

    The steps which you suggested me to do has solved my problem. There was one task whose priority was higher than Task.numPriorities. I figured it out while performing steps you mentioned above. Can you tell me function and use of Task.numPriorities??

    Here I am posting screen capture of ROV for others users.

    Task->Detailed

    Hwi->Module

    Hwi->Detailed

    BIOS->Module

    BIOS->Scan for errors

    Best Regards,

  • Making Task.numPriorities smaller saves some footprint. We maintain a table where the length is determined by Task.numPriorities. We shrunk the number down for the driver examples to help minimize footprint.

    Graphically you can change it here:
