ccs v6 and cc3200: trouble reading peripheral registers

Other Parts Discussed in Thread: CC3200

I'm looking for a way to see the cc3200 peripheral registers through CCS v6, how do I do?

The Registers view show only the core registers and when I try to read the memory block allocated for TIMERA0 I get:

Cortex_M4_0: Trouble Reading Memory Block at 0x40030000 on Page 0 of Length 0x100: Debug Port error occurred.

I have a CC3200 LaunchXL dev board.

Greetings

Attilio

    As per this post, the peripheral registers currently cannot be viewed in the CCS Registers view.

    An alternate way to view them would be to open a memory view at the register address.

    When I read the register address through the "Memory Browser" view I get:

    Cortex_M4_0: Trouble Reading Memory Block at 0x40030000 on Page 0 of Length 0x100: Debug Port error occurred.

    Per this post, you need to enable the peripheral clock using PRCMPeripheralClkEnable() API before accessing peripheral registers. Have you done that already?

    If you are still having trouble with this, I would suggest starting a new thread in the SimpleLink CC31xx/CC32xx forum as the experts there should be able to help better with this.

    Yes, PRCMPeripheralClkEnable() API is invoked: the problem arises when loading the interrupt example project coming with the CC3200 SDK.

    Thanks for the suggestion, eventually I will repost on the cc3200 forum.

    I posted here because I supposed that this was a CCS problem: compiling with gcc and using openocd the cc3200 memory registers are visualized as expected.

    Ok,

    The reported problem was caused by my wrong debug session, CCS works correctly:

    setting correctly the breakpoint after  PRCMPeripheralClkEnable() the peripheral registers values are displayed.

    Thanks for your support
