TMS570LS1224: TMS570 Bootloader using IAR EWARM V8.22

Part Number: TMS570LS1224
Other Parts Discussed in Thread: HALCOGEN,

Hi,

I am using IAR EWARM V8.22 for development and following the SPNA192 document for Bootloader for Hercules TMS570LS12x MCU.

However I am not able to compile the project. Could you please suggest me a solution.

Do you suggest that the linker file provided for CCS project has to be modified to support IAR?

Thanks and regards,

Abrar

    I am using using the sys_link.cmd file generated using HALCOGEN for the IARv8.22

    I am getting the following errors:

    Hi Abrar,

    IAR Workbench uses different linker cmd file. Please use HALCoGen to generate one for IAR workbench:

    Hi,

    Thanks for your reply.
    I have used sys_link.cmd generated from HALCoGen for IAR workbench.

    The following are the contents of sys_link.cmd
    /*----------------------------------------------------------------------------*/
    define memory mem with size = 4G;

    define region VECTORS = mem:[from 0x00000000 size 0x00000020];
    define region FLASH = mem:[from 0x00000020 size 0x0013FFE0];
    define region STACK = mem:[from 0x08000000 size 0x00001500];
    define region RAM = mem:[from 0x08001500 size 0x0002EB00];
    define block HEAP with size = 0x800, alignment = 8{ };

    initialize by copy {readwrite};
    do not initialize {section .noinit};

    place in VECTORS {readonly section .intvecs};
    place in FLASH {readonly};
    place in RAM {readwrite};
    place in RAM {block HEAP};
    /*----------------------------------------------------------------------------*/


    But I am getting the following compilation errors:

    Error[Li005]: no definition for "copy_in" [referenced from D:\SafetyMCU_Bootloader\object\Debug\Obj\sys_startup.o]
    Error[Li005]: no definition for "_copyAPI2RAM_" [referenced from D:\SafetyMCU_Bootloader\object\Debug\Obj\sys_startup.o]

    The assembly function "_copyAPI2RAM_" is based on the CCS linker commmand file. The sys_startup.c should not call __TI_auto_init();

    You can write C code to copy flash API from flash to SRAM at the beginning of main().

    Hi,

    I have given the lib path for F021_API_CortexR4_BE.lib and modified the linker file as follows:

    /*----------------------------------------------------------------------------*/
define memory mem with size = 4G;

define region VECTORS = mem:[from 0x00000000 size 0x00000020];
define region FLASH   = mem:[from 0x00000020 size 0x0013FFE0];
define region STACK   = mem:[from 0x08000000 size 0x00001500];
define region RAM     = mem:[from 0x08001500 size 0x0002EB00];
define block HEAP with size = 0x800, alignment = 8{ };

initialize by copy { readwrite };
initialize by copy { object bl_flash.o };
initialize by copy { object F021_API_CortexR4_BE.lib };
do not initialize  {section .noinit};

place in VECTORS {readonly section .intvecs};
place in FLASH   {readonly};
place in RAM     {readwrite};
place in RAM     {block HEAP};
/*----------------------------------------------------------------------------*/

    However, when I try to read from flash, I get the following error in IAR.

    Please could you suggest a solution.

    Thanks and regards,
    Abrar

    Since I am using IAR EWARM V8.22 and the microcontroller TMS570LS1224 (big endian), I tried the following:
    1) In the file CGT.IAR.h, I modified the line
    #if !defined(__LITTLE_ENDIAN__) /* is big endian compile */
    to
    #if (__LITTLE_ENDIAN__ == 0) /* is big endian compile */
    2) For making the F021_API_CortexR4_BE.lib & bl_flash.c to run from RAM, I added the following lines to the linker file:
    initialize by copy { object bl_flash.o };
    initialize by copy { object F021_API_CortexR4_BE.lib };
    3) I had to setup the following before accessing the flash:
    a) FRDCNTL_bit.RWAIT = 0; // Since I am running less than 50MHz
    b) FSM_WR_ENA_bit.WR_ENA = 5; // Enabling write enable
    c) EEPROM_CONFIG = 2 // EEPROM wait configure.
    d) FSM_WR_ENA_bit.WR_ENA = 2; // Disable write enable
    4) Disable interrupts ( _disable_interrupt_() ) before accessing the flash and enable interrupts ( _enable_interrupt_() ) after flash access is complete.
    5) I had to ignore the following warning:
    Warning[Lt009]: Inconsistent wchar_t size
    Read.MarginByByte.obj(F021_API_CortexR4_BE.lib)
    and 15 other objects have wchar_t size 16 bits
    adc.o and 72 other objects, some of them in dl7Sx_tbn.a
    and 12 other libraries have wchar_t size 32 bits

    As per the post on: e2e.ti.com/.../746903
    The only workaround for now is to downgrade the IAR Workbench.

    Is the problem caused by the different wchar_t definition? If you switch back to old version IAR workbench, does the problem gone?

    Hello Abrar,

    Have you solved the problem?

    Hi,

    The compilation errors are resolved and flash read / write / erase are working in IAR EWARM 8.22.

    I did not switch back to old version IAR workbench, so there is a warning for inconsistent wchar_t size in F021_API_CortexR4_BE.lib.
    As of now, I did not find any problem caused because of that warning.

    Thanks a lot for your continued support.

    Abrar
