flash_prog_erase

This example is a demo project to P/E (Program/Erase) main-area of eFlash.

The execute-bin will occupy front area of eFlash, as the result P/E the other area of eFlash

There are 3-case in this example

• word data
• half-word data
• byte data

The execute-flow of every case:

• Erase eFalsh (secotr by sector) and verify word-data is 0xFFFFFFFF or not

  If the word-data is NOT 0xFFFFFFFF, it will stop procedure and log error message

• Program word/hword/byte-data to eFlash and verify the result value of eFlash

  If the data is NOT match, it will stop procedure and log error message

It also supports fix/random pattern

• Fix pattern is 0x5A5A5A5Aul
• Random pattern

  User should modify CONFIG_USE_RAND_DATA as below

  // at main.c
  /**
   *  Use random data as pattern
   */
  #define CONFIG_USE_RAND_DATA        1
  

If user wants to get more detail message, unmark CONFIG_MORE_MESSAGE definition

// at main.c
/**
 *  Get more log message
 */
#define CONFIG_MORE_MESSAGE

Log

Use serial port with baudrate 115200, 8bit, no parity check.
