The problems of Fee in MCAL module based on TMS570LS0714 chip

Hello Hong,

After Fee_Init is called, please check the value in variable TI_Fee_GlobalVariables[0].Fee_Error. If it shows Error_SetupStateMachine, it means the Ewait states is not correctly configured. Please check device data sheet and configure correct EWAIT state. Fls module initializing is not required.

Hi Vishwanath，

   After Fee_Init is called, the value in variable TI_Fee_GlobalVariables[0].Fee_Error is 0xff(see Figure 1).

   In addition, When I set a breakpoint in Fee_Init(), let the program run to Fee_Init(), then set a breakpoint in Fee_Write(), let the program continue to run, the program does not

run to  Fee_Write(), but jumps to Fee_Init().

                                                                                                                                  Figure 1

Hi,

Looks like FEE sections are not correctly assigned in linker command file. Below is an example of FEE memory sections. Please check if you have similar settings in your linker command file.

FEE_TEXT_SECTION : {} > FLASH0 | FLASH1
FEE_CONST_SECTION : {} > FLASH0 | FLASH1
FEE_DATA_SECTION : {} > RAM

Hi  Vishwanath，

     There are't similar FEE sections settings in my linker command file(see Figure 1 and Figure 2).

                                                                                                                      Figure  1

                                                                                                                             Figure 2

   Should  I  add  FEE sections in SECTIONS of  Figure 2 ?  How to add ? Can you provide me an example for reference ？  I‘m a green hand. :)

Thanks and Regards,

Hi Vishwanath，

  Now, the value in variable TI_Fee_GlobalVariables[0].Fee_Erro  shows Error_SetupStateMachine（see Figure 1） . As you said, it should the Ewait states is not correctly configured.

                                                                                                                             Figure 1

  I spend a lot of time studying device data sheet(TMS570LS0714), but I don't know How to configure correct EWAIT state. Instruct me:)

Thanks and Regards,

Hi,

Are you using HALCoGen as startup code? Is yes, following piece of code does(write to EEPROM_CONFIG_HL) the setting of wait states for FEE bank.

void setupFlash(void)

{

/* USER CODE BEGIN (6) */

/* USER CODE END */

   /** - Setup flash read mode, address wait states and data wait states */

   flashWREG->FRDCNTL =  0x00000000U

                      | (uint32)((uint32)3U << 8U)

                      | (uint32)((uint32)1U << 4U)

                      |  1U;

   /** - Setup flash access wait states for bank 7 */

   FSM_WR_ENA_HL    = 0x5U;

   EEPROM_CONFIG_HL = 0x00000002U

                    | (uint32)((uint32)3U << 16U) ; /*EWAIT states */

/* USER CODE BEGIN (7) */

/* USER CODE END */

   /** - Disable write access to flash state machine registers */

   FSM_WR_ENA_HL    = 0xAU;

   /** - Setup flash bank power modes */

   flashWREG->FBFALLBACK = 0x00000000U

                         | (uint32)((uint32)SYS_ACTIVE << 14U) /* BANK 7 */

                         | (uint32)((uint32)SYS_ACTIVE << 2U)  /* BANK 1 */

                         | (uint32)((uint32)SYS_ACTIVE << 0U); /* BANK 0 */

/* USER CODE BEGIN (8) */

/* USER CODE END */

}

In data sheet, page 42 has following. Based on the frequency of the device, you need to configure correct EWAIT states.

Hi Vishwanath ,

  I'm using HALCoGen as startup code and using  PGE，160MHz（see Figure 1 and Figure 2）. Do you  realize  160MHz  in your code? If not, Should I modify in your code?Instruct me.:)

Hi,

Please refer system.h file for operating frequency. Normally GCLK_FREQ/HCLK_FREQ is the CPU operating frequency. In system.c file, refer setupFlash() and verify if the wait states are configured correctly.

FEE operating frequency should be same as the frequency configured in system.h file.

Hi Vishwanath,

   How to verify if the wait states are configured correctly? Because I am specializing in MCAL, I am not familiar with the operation of the TMS570 chip and registers. Please instruct me.:)

Hi,

    Fee_Init passed, but it can't be written(See Figure 1).Please instruct me.:)

                                                                                                                            Figure 1

Hi,

After Fee_Init is called, please check the value in variable TI_Fee_GlobalVariables[0].Fee_Error. Is Fee_Init was successful, sector header should have been written into FEE bank.

Hi，

    Now，Fee module can write and read(see Figure 1)，but the frequency at which Flash will operate isn't  160MHz ，but 80MHz .  Can  the frequency of Flash be operate in 160MHz? If any ,what should I do?

                                          

                                                                                                      Figure 1

Thanks and Regards

Hi,

FEE can operate at 160MHz. You need to correctly configure frequency in HALCoGen and generate the files. Verify if the Ewait state is generated correctly. In next step, configure the same frequency in EBTresos and generate files. Run Fee_Init any verify if data is getting written to sector header.

Hi,

    How  correctly configure frequency in HALCoGen ? Can you provide some pictures about it?

Thanks and Regards,

Yunqiang Hong.

Hi,
I have correctly configure 160MHz in HALCoGen and generate the files, but it can't pass Fee_Init(). However, 80Mhz is work.
Why?
Thanks and Regards
Yunqiang Hong.

Hi,

   I know that you have revised minor problems on PORT  in the previous version of the code in order to being consistent to the code which EB configuration tool generates?

    Have you ever configured  FEE in the EB configuration tool and tested it please?

Thanks and Regards
