G Errata

Advisory 1:

  • Incorrect Revision number returned by the Fapi_getLibraryInfo() of FAPI_F28003x_EABI_v1.58.10.lib

Flash API Version affected:

  • FAPI_F28003x_EABI_v1.58.10.lib.

Details:

  • Fapi_getLibraryInfo() is incorrectly coded to return the Revision number value as 01 instead of 10. If the application does not use this function, then this advisory is not applicable.

WorkAround:

  • User application should treat 01 as 10.

Advisory 2:

  • DCSM OTP programming is not supported by the FAPI_F28003x_EABI_v1.58.10.lib for F280033/34 devices. This advisory is not applicable for non-F280033/34 devices.

Flash API Version affected:

  • FAPI_F28003x_EABI_v1.58.10.lib.

Details:

  • FlashAPI programming command is blocking the programming of DCSM OTP range. If the F280033/34 user application does not program the DCSM OTP, then this advisory is not applicable.

WorkAround:

  • If the F280033/34 user application needs to program DCSM OTP, then FAPI_F280033_34_EABI_v1.58.11.lib should be used. Non-F280033/34 users should continue to use the FAPI_F28003x_EABI_v1.58.10.lib.
