RTOS/CC2640: BIOS_start() exist showing an exception

Mujahid Abbas

Part Number: CC2640

Tool/software: TI-RTOS

Hello,

I am trying to run simple_peripheral example on CC2640 with custom board. First i built the stack and flashed CC2640, then i built the application and start debugging.

When the debugger tries to cross the BIOS_start() function. it shows following Warning!!

Stopped at unknown breakpoint.

During debug session i watched the values of some variables used in BIOS_start() using watch window.

but there values remain same before and after execution of BIOS_start(). These variables are highlighted in following figure. It also shows an exception occurred as shown in red box.

How i can solve this problem?? I am using IAR workbench 7.70.2, I-jet with CC2640.

Waiting for your kind help.

From the TI-RTOS menu, open the Hwi Exception view:

The decoded exception, register context information, and call stack in the view window might provide good clues to understand the problem.

Since you running this on your custom CC2640, I suspect there is something wrong with your HW. Can you specify which CC2640 chip do you use ? Is it 7x7 VQFN48, 5x5 VQFN32, or 4x4 VQFN32?

I agree with YK. Please see the Board Bring Up section in the SW user guide. It's likely you have a misconfigured IO on your board that is causing the abort. Beyond that, there's not much more we can offer since there is not sufficient details in your post, such as any changes made from the TI reference design.
