TM4C129ENCPDT: eeprom_pb multible parameter blocks

Hi lukas,

  Below is the note in the beginning of the eeprom_pb.c file. Yes, you can store multiple paramter blocks in the eeprom. 

//*****************************************************************************
//
//! \addtogroup eeprom_pb_api
//! @{
//!
//! This module is based on the flash_pb module, which uses flash sectors at
//! the end of flash memory to store application parameter blocks. This module
//! replaces the use of flash memory with the use of the EEPROM module,
//! available in some Tiva devices.
//!
//! This module does not attempt to optimize the usage of EEPROM memory, but
//! instead creates an API that will allow a very easy drop-in replacement in
//! applications that are already using the flash_pb module.
//

Hi Charles,

i probably didnt specify my question enough. Would it be possibele to init PBs at different addresses with different sizes. Since i dont know how to get the actual PBs back, because g_pui8FlashPBCurrent is a global variable.

Thanks in advance!

regards,

Lukas

Hi Lukas,

  Reading the description of EEPROMPBInit(), you can specify the start address and size of a new parameter block.  Make sure of the special requirement highlighted in red as described below. Can you give a try?

/*****************************************************************************
//
//! Initializes the eeprom parameter block.
//!
//! \param ui32Start is the offset from the beginning of the EEPROM memory to
//! be used for storing the parameter block; this must be an integer multiple
//! of 4 (that is, word aligned)
//! \param ui32Size is the size of the parameter block when stored in flash;
//! this must be an integer multiple of 4 (that is integer number of words).
//!
//! This function initialize the EEPROM module to be used for parameter block
//! storage.
//!
//! A parameter block is an array of bytes that contain the persistent
//! parameters for the application. The only special requirement for the
//! parameter block is that the first byte is a sequence number (explained
//! in EEPROMPBSave()) and the second byte is a checksum used to validate the
//! correctness of the data (the checksum byte is the byte such that the sum of
//! all bytes in the parameter block is zero).
//!
//! This function must be called before any other eeprom parameter block
//! functions are called.
//!
//! \return 0 if successfully intialized, 1 otherwise.
//
//*****************************************************************************

EEPROMPBInit(uint32_t ui32Start, uint32_t ui32Size)
