TMS570LS0714: the FEE issue of Fapi_initializeFlashBanks function

Part Number: TMS570LS0714

Hi TI,

when I fulfill the FEE module, I has stopped by the function of Fapi_initializeFlashBanks((uint32)TI_FEE_OPERATING_FREQUENCY), which TI_FEE_OPERATING_FREQUENCY=180.

The initialization can't pass the function of Fapi_initializeFlashBanks function. And the function is blong to TI F021 Flash Library, so I can't see more detail information of the function.

So,could you tell me something about this function and help me with this issue?

Thanks and regards,

Duan

    Hello Zhenzhen,

    The TMS570LS0714 device has two packages: 144-pin PGE package and 100-pin PZ package. The 144-pin PGE package supports up to 160MHz system clock, but the maximum system clock frequency of the 100-pin PZ package is 100MHz.

    180Mhz is beyond this limitation.

    The wait state for FEE should be programmed correctly. If the system clock is 160MHz, the EWAIT be 9.

    Please refer to the device datasheet: SPNS226E
