Why Flash_Compact_B cause TMS470MF06607 reset?

Hello:

I have forwarded your issue to our Flash API expert. He should get back with you soon.

Hello dong lu,

Request you to provide the following details so that I can undestand the scenario better:

1. What is the version of the Flash API ?

2. What are the steps performed before calling the Flash_Compact_B() function?

3. Is the code executed from RAM or Flash?

Best Regards,

Siddharth

Hi, Siddharth Deshpande.Tank your help!

1,I Use Flash the f035 .In  my program ,I use 

      #include "f035.h"

      #include "flash470.h"

2.  I call  the Flash_Compact_B() in main

   void main(void)
    {
     int i=0,j=0;
     FLASH_STATUS_ST status;
    sciInit();
    sciEnableNotification(sciREG1,SCI_TX_INT);
    NVIC_enable();

    //rti

    rtiInit();
     rtiEnableNotification(rtiNOTIFICATION_COMPARE0);
    rtiStartCounter(rtiCOUNTER_BLOCK0);
    NVIC_enable();

    / /0ut clock
    _set_ecp_clk();
    for(i=0;i<10;i++)
   {
     BOOL mt0=Flash_Compact_B(0x00000000,0,i,50,(FLASH_ARRAY_ST)0xFFE87000,&status);
  }
    //BOOL mt1=Flash_Erase_Bank_B(0x00000000,0x80000,0,50,(FLASH_ARRAY_ST)0xfff87000,&status);

  while(1)
  {

   }

3 I use the halcogen create the program .I'm newer and donnot know executed framram or flash,The linkcmd is:

MEMORY

}

You look this,tell me where my error is?,Thank you

Hi dong lu,

I observe from the linker command file that the code is executed from Flash Bank 0 and also you are trying to erase Bank0 itself. This is not possible since  Flash memory is inaccessible for reads during erase operation which includes code execution until the operation has completed. You should modify the linker command file to execute the code from RAM. Please try executing the code from RAM and let me know your observations.

Thanks,

Siddharth

HI,Siddharth Deshpande,I do like you say,but The program run at the Flash_Compact_B() and stop. My program is:

MEMORY

I don not know  why.Can you give me an example or demo .(In your web ,have the "6712.flash-operation-demo.rar",But I can not download the file.My email is 13308019871@189.cn.Tank you very much!

Hi dong lu,

Can you share your HalCoGen project and source code?  I will have a look at it and see if something is missing.

Also, let me know what is the system frequency?

Best Regards,

Siddharth

hi， Deshpande。This is myproject.3480.mydingxiang(TI).rar.

Thank you Help me to find the questions!

Hi dong lu,

As mentioned earlier,  Flash operations cannot be carried out on the same bank which contains the executable code. Also I observed that the parameter passed to Flash_Compact_B function was incorrect :  FLASH_ARRAY_ST)0xFFE87000 should have been FLASH_ARRAY_ST)0xFFF87000.

Have modified the linker command file to execute from RAM. Please refer the attached code and see if it solves your issue.

Thanks,

Siddharth

Hi,Siddharth.I do like you say,load my program to tms470mf06607 add the below code in sys.cmd.but it do not to work.

but I change the below code ,it work

.bss : {} > RAM

I do not understand  the"

 .flashapi : load = FLASH0, run = RAM, LOAD_START(FlashApi_LoadStart), LOAD_END(FlashApi_LoadEnd), LOAD_SIZE(FlashApi_LoadSize), RUN_START(FlashApi_RunStart), RUN_END(FlashApi_RunEnd), RUN_SIZE(FlashApi_RunSize),

load((char *)FlashApi_LoadStart, (char *)FlashApi_RunStart,(unsigned int)FlashApi_LoadSize);

 "".if is it necessary?,I want the whole example to operate the flash for tms470mf06607,I hope you can help me.Tankk you!
