TMDSDOCKH52C1: Unable to Initialize M3

Clarence Roopnarine13

Part Number: TMDSDOCKH52C1

I'm evaluating the F28M35H5C2 on the H52C1 Concerto Experimenter Kit . I've read the workshop document. Tried to create a simple project that supposed to blink the LED attached to Port C Pin 7. I can get pass initialization of the intrerupt table but when ever I add code to initialize the other peripherals (GPIO and GPTM); after the program loads the debugger do not stop on main. Looked at the map file all address reported are correct.

Below are the details of the development environment:

Windows 10.

CCS v9.2

Attached is the sample project. If I comment out the gpio_init function in file file psp.c I can debug; adding any other function breaks. Any suggestion is appreciated.

I've notice also in the Register View Window that the reported values for almost all peripherals are "Error:un

able to read".

Hi,

We are looking into the issue. We will get back to you by Friday.

Found that the clock to the a peripheral must be enabled for the debugger to read and display their register values. Also if I used statements like:

volatile struct GPIO_REGS* pRegs;

pRegs = ( ( volatile struct GPIO_REGS* )( 0x4005A000 ) );

and comment out the entries in the .cmd file i'm able to get pass the initialization.

Still no sure why is fails when declared in .cmd file.

Hi,

I am not sure if I got your question right. Can you share the code snippet in the cmd file which you have commented out.

Hi,

It's attached. You can ignored the USB section.

Thanks.

HI,

GPIOxRegister struct is actually defined in the F28M35H52C1_GlobalVariableDefs.c. In the linker command file, these sections are mapped to the correct register addresses.

The struct GPIOCRegs should be available at address 0x4005A000
