12.1 General

Question: I cannot find the EEPROM and EEPROM_PingPong projects, where are they?:

DeviceBuild ConfigurationsLocation
F28003xRAM, FLASHC2000Ware_6_00_xx_xx > driverlib > f28003x > examples > flash
F28P65xRAM, FLASHC2000Ware_6_00_xx_xx > driverlib > f28p65x > c28x > examples > flash
F28E12xROM, FLASH

C2000Ware_6_00_xx_xx > driverlib > f28e12x > c28x > examples > flash

Question: What are the first things I must check if the EEPROM project encounters an error?

Answer:

  • View the configuration file (EEPROM_Config.h, EEPROM_PingPong_Config.h) and check the provided options for the following: Device variation, programming mode (64 bit vs. Page), Flash Bank selection, Flash sector size, number of Flash sectors, number of EEPROM banks, number of EEPROM pages, data size of EEPROM pages. Also, check the main program file (EEPROM_Example.c, EEPROM_PingPong_Example.c) to see if the correct Flash Sector locations are being used for EEPROM Emulation. If an incorrect first and last sector value are provided, an error occurs and be seen in the EEPROM_Config_Check function. The EEPROM_Config_Check function provides general information for error checking.
  • Make sure that the protection masks are enabled/disabled for the appropriate sector(s) selected for EEPROM Emulation for your device, consulting the device's Flash API reference guide for more information.
  • One area of the program to check would be the linker command file - make sure all flash sections are aligned to 128-bit boundaries. In SECTIONS, add a comma and "ALIGN(8)" after each line where a section is allocated to flash.
