4.1.11 Major Device Revision

Revision(s) Affected: 0

There were significant changes to the device functionality between Revision 0 and Revision A.

Code developed on the revision 0 device may not operate as expected on later revisions. The Concerto F28M35x Technical Reference Manual and the F28M35x Concerto™ Microcontrollers Data Manual are updated to reflect the functionality present on revision A and later device revisions. Some specific areas of change are:

  • GPIO configuration
  • EPI additional functionality
  • USB emulation:
    • From revision A onwards, "extended ICEPick router support" in the target configuration has to be enabled for the USB emulators to halt the Cortex-M3 core.
  • Flash programming:
    • From revision A onwards, the latest Flash API should be used without modifying the Fapi_setupBankSectorEnable(void) function in the Fapi_UserDefinedFunctions.c file.
    • Code Composer Studio™ and UniFlash should be checked for the latest updates for installing the XMLs required for the Flash plugin to work with revision A and revision B devices.
