Flash APi functions for F035 stucks

Other Parts Discussed in Thread: TMS570LS10206

Dear all,

i'm writing flashing routines for TMS570LS10206. I included pf035a_api_eabi_vfp.lib and the headers succesfully. I get correct answer from return Fapi_getApiVersion32() but all the functions that interact with flash module doesn't return. I checked the Program Counter and I found it in a correct state, I checked Flash Module register and I enabled all banks and sectors, I'm still in privileged mode and all typedef are taken from original flash470.h.

Here's my code:

#define PLATFORM

#include ".\inc\f035.h"
#include ".\inc\flash470.h"
#include ".\inc\main.h"

#pragma INTERRUPT(_c_int00, RESET)
#pragma CODE_SECTION (main , ".main" )

int main(void);

void _c_int00()
{
    main();
}

// Definitions for System Module registers used to affect HCLK/
#define PLLCTL1 (*(volatile unsigned int *) 0xffffff70)
#define PLLCTL2 (*(volatile unsigned int *) 0xffffff74)
#define GHVSRC (*(volatile unsigned int *) 0xffffff48)
#define CSVSTAT (*(volatile unsigned int *) 0xffffff54)
#define CLKCNTROL (*(volatile unsigned int *) 0xffffffd0)
#define SYSPC1 (*(volatile unsigned int *) 0xFFFFFF00)
#define ECPCNTL  (*(volatile unsigned int *) 0xFFFFFFD4)

// Definitions for Flash Module
#define F035_FBPROT     (*(volatile unsigned int *) 0xFFF87030)
#define F035_FMAC         (*(volatile unsigned int *) 0xFFF87050)
#define F035_FBSE         (*(volatile unsigned int *) 0xFFF87034)
#define F035_FRDCNTL     (*(volatile unsigned int *) 0xFFF87000)

int main(void)
{
     unsigned long instr_code;
    unsigned long start_addr;
    unsigned long size;
    unsigned long data32_par;
    unsigned short chksum;
    unsigned short i;
    unsigned long ret_val;
    unsigned char *ptr_data;
    UINT32 len = 0x10;  //debug
    UINT32 buff[128];     //debug

    // Flash Protection settings
    F035_FRDCNTL = 0x0;
    F035_FBPROT = 0x1;            // Disable protection
    F035_FMAC = 0x0;                // Select bank 0
    F035_FBSE = 0x000003FF;        // Enable flash operations on all sectors of bank 0
    // DEBUG: DO THE SAME FOR FLASH 1

    // Clock settings
//    GHVSRC = 0x01010001;                                          // Select PLL as clock source for HCLK and VCLK
    SYSPC1 = 1;                                                   // Enable ECPCLK
//    CLKCNTROL = 0x0;                                               // SET VCLK2=VCLK=HCLK
    CLKCNTROL = 0x00000100;                                      // SET VCLK2=VCLK=HCLK/2
    GHVSRC = 0;                                                     // Oscillator is the clock source for everything
    ECPCNTL = 0x00800009;                                         // Enable ECLK continue on suspend
                                                                // ECLK = VCLK/10

    PSPWRDWNCLR0 = 0xFFFFFFFF;                                    // Powers up clock to all peripherals
    PSPWRDWNCLR1 = 0xFFFFFFFF;
    PSPWRDWNCLR2 = 0xFFFFFFFF;
    PSPWRDWNCLR3 = 0xFFFFFFFF;


    for(;;)
    {
        Read(ptr_data, (unsigned char*)(&instr_code), WORD, NULL_PTR, NULL_PTR, NULL_PTR);
        if(instr_code == MASS_ERASE_FLASH_INSTR_CODE)
        {            Flash_Read_V((UINT32*)0x0, buff, len, 0, FLASH_CORE0, (FLASH_ARRAY_ST)0xfff87000);    //   <--- STUCK!
            Write(ptr_data, (unsigned char*)&ret_val, WORD, CLOSE);
        }
     }

Here's my compiler options:

-mv7R4 --code_state=32 --float_support=VFPv3D16 --abi=eabi -O0 --opt_for_speed=0 -g --include_path="C:/ti/ccsv5/tools/compiler/tms470/include" --diag_warning=225 --display_error_number --enum_type=packed --asm_listing


Moreover, on TMS570 TRM i found that writing '111' on FMAC register allows user to read #banks - 1. According to device specifications I should have 2 banks, so I should read a value of '0x1', I read instead a value of '0x3'.

Thanks a lot, best regards,

Samuele Stefanoni

  • Are you executing the code from Flash or RAM?

  • Hi John,

    I'm executing code from RAM.

    Best Regards

  • Hi all,

    I solved this problem changing from --code_state=32 to --code_state=16 as API flash are compiled in Thumb. Now resolving this issue has changed the behaviour of the device.

    I run correctly Flash_Blank_B and Flash_Read_V functions, but changing it with Flash_Compact_B and Flash_Erase_Bank_B stucks the firmware. To be precise, uncommenting Flash_Erase_Bank_B or Flash_Compact_B hangs the firmware already on Read funcion call.
    Here's my resulting .map

  • Hello Samuele,

    I would need to see the actual code and call to the functions that you are indicating are getting stuck.

  • Hello, Samuele:

    I had the same exact problem and symptoms you're describing in this forum. I determined that I was not setting up the stack pointer correctly. To set up the stack pointer, include the following code to the beginning of int main(void):

    #include "intrinsics.h"
    #define VTOR (*(UINT32*)0xFFFFFFAC)    // Vector table offset register
    #define INTVEC ?????                                  // Address of vector table

    __set_MSP(*(volatile UINT32*)INTVEC);     // Set the stack pointer to the value in the vector table
    VTOR = (INTVEC | (0x40000000));                // Bit 30 is set to indicate SRAM

    INTVEC is the address of your interrupt vector table (usually displays as .intvec).

  • Hi Jonathan,

    thank you for your suggestion. At the end I had a private conversation with Mr. John Hall which packed to me a complete project for CCS studio with all the necessary initializations.

    I can't verify what you wrote above, but I believe that this could be the solution of my issue.

    Thank you,

    Samuele Stefanoni
