TMS570LS0714: TMS570LS0714

Hi,

I am debugging the TMS570LS0714 flash with F021, and I found that the Fapi_initializeFlashBanks function returns the error Fapi_OtpChecksumMismatch.

I have set SYS_CLK_FREQ to 100MHz, RWAIT to 1,and EWAIT to 5.

The code as follows:
status = (Fapi_initializeFlashBanks((uint32_t)SYS_CLK_FREQ));
if (status == Fapi_Status_Success)

I have also noticed that FallbackPower mode register does not try to activate bank0 and bank 7, even though when i hardcode it to activate both of them

When I try to see FBusy register, it shows both of the banks are not implemented.

Is there anything Im missing while initializing the flash?

The initialization follows as:

flashWREG->FRDCNTL =  0x00000000U
                       | (uint32)((uint32)1U << 8U)
                       |  1U;

    /** - Setup flash access wait states for bank 7 */
    FSM_WR_ENA_HL    = 0x5U;
    EEPROM_CONFIG_HL = 0x00000002U
                     | (uint32)((uint32)5U << 16U) ;


    /** - Disable write access to flash state machine registers */
    FSM_WR_ENA_HL    = 0xAU;

    /** - Setup flash bank power modes */
    flashWREG->FBPWRMODE = 0x00000000U
                          | (uint32)((uint32)3 << 14U) /* BANK 7 */
                          | (uint32)((uint32)3 << 0U); /* BANK 0 */

Thanks
