C28m35 Concerto problem

Other Parts Discussed in Thread: CONTROLSUITE, SYSBIOS

Hi,

I am new ti/concerto/ccsv5 and playing around with a c28m35 controlcard to learn more. I am trying to convert the blinky_dc_28 and blinky_dc_m3 example provided by the controlSuite package to SYSBIOS project. I have successfully converted the the blinky_dc_28 code, but when I try to convert the m3 code I am getting some trouble. Below is the error code outputted by the ccsv5. I hope someone could help me to figure out what I have done wrong

#66 expected a ";"      blinky_SYSBIOS_M3                      line 29, external location: C:\ti\controlSUITE\device_support\f28m35x\v150\F28M35x_headers\include\F28M35x_Device.h       C/C++ Problem

#66 expected a ";"      blinky_SYSBIOS_M3                      line 30, external location: C:\ti\controlSUITE\device_support\f28m35x\v150\F28M35x_headers\include\F28M35x_Device.h       C/C++ Problem

Here is what I added to a generic SYSBIOS swi M3 example:

#include <xdc/std.h>

#include <xdc/runtime/System.h>

 

#include <ti/sysbios/BIOS.h>

#include <ti/sysbios/knl/Swi.h>

#include <ti/sysbios/knl/Task.h>

#include <ti/sysbios/knl/Clock.h>

#include <ti/sysbios/knl/Semaphore.h>

 

#include <xdc/cfg/global.h>

 

//***** Extra added header files (in addition to header files added by SYSBIOS) *****//

#include <hw_memmap.h>

#include <hw_gpio.h>

#include <hw_types.h>

#include <hw_sysctl.h>

#include <sysctl.h>

#include <gpio.h>

In main:

    //*************** Code added *****************//

    // Disable Protection

    HWREG(SYSCTL_MWRALLOW) =  0xA5A5A5A5;

 

    // Sets up PLL, M3 running at 100MHz and C28 running at 100MHz

    SysCtlClockConfigSet(SYSCTL_USE_PLL | (SYSCTL_SPLLIMULT_M & 0xA) |

                         SYSCTL_SYSDIV_1 | SYSCTL_M3SSDIV_1 |

                         SYSCTL_XCLKDIV_4);

    // Enable clock supply for GPIOC

    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOC);

 

 

    // Give C28 control of Port C pin 6 (flashed from c28x kernal)

    GPIOPinConfigureCoreSelect(GPIO_PORTC_BASE, 0x40, GPIO_PIN_C_CORE_SELECT);

 

    // Disable clock supply for the watchdog modules

    SysCtlPeripheralDisable(SYSCTL_PERIPH_WDOG1);

    SysCtlPeripheralDisable(SYSCTL_PERIPH_WDOG0);

 

 

    BIOS_start();

 

 here is the external files which the compiler is complaining at:

extern __cregister volatile unsigned int IFR; (line 29 in F28M35x_Device.h)
extern __cregister volatile unsigned int IER; (line 30 in F28M35x_Device.h)

    Hi Jorgen,

    extern __cregister volatile unsigned int IFR; (line 29 in F28M35x_Device.h)
    extern __cregister volatile unsigned int IER; (line 30 in F28M35x_Device.h)

    this header file is to be used by the C28.

    Code for the the M3 should be referencing the header files in the "MWare" sub-directory. (e.g. \device_support\f28m35x\v150\MWare\..)

    If you take a look at the MCU SDK (TI-RTOS) product, you'll find examples and documentation on how to use SYS/BIOS on concerto's M3.

    Hi Tom,

    Thx for reply, I have now change the include path to the MWare directory and included the wanted .c files directly into the project. I now get some problem with some unresolved symbol

    #10010 errors encountered during linking; "blinky_SYSBIOS_M3.out" not          blinky_SYSBIOS_M3                                     C/C++ Problem

    <a href="file:/C:/ti/ccsv5/tools/compiler/dmed/HTML/10099.html">#10099-D</a>  run placement fails                F28M35x_Headers_BIOS.cmd  /blinky_SYSBIOS_M3    line 115                C/C++ Problem

    <a href="file:/C:/ti/ccsv5/tools/compiler/dmed/HTML/10234.html">#10234-D</a>  unresolved symbols remain                blinky_SYSBIOS_M3                                     C/C++ Problem

    unresolved symbol WatchdogRunning, first referenced in ./sysctl.obj  blinky_SYSBIOS_M3                                     C/C++ Problem

     

    The only error message that I could trace ends in F28M35x_Headers_BIOS.cmd file and complains on the following line:

    PieVectTableFile        : >  PIEVECT,   PAGE = 1

    now the project is getting linked to a C28 linker.cmd file.

    I'd try to create an example SYS/BIOS project (Project >> New CCS Project) from the project wizard (or try the MCU SDK's example project linker.cmd file) and copy that .cmd file into your project.

    Thanks Tom,

    Now my led is flashing :)

    Cheers
