flash_prog_erase_nvr

This example is a demo project to P/E (Program/Erase) NVR area of DUT (execute at main-flash)

This example is only for internal verification. We do NOT expect user to modify data of NVR

• There are 8-KBytes (sector 0 ~ 15) in NVR area

  A sector size is 512 bytes

  • The 15-th sector is recorded the paraments of embedded flash
  • The 14-th sector is recorded the trim-values

• It supports 3 type (read 8/16/32 bits) to verify data

  // at main.c
  #define CONFIG_USE_READ_WORD
  /* #define CONFIG_USE_READ_HWORD */
  /* #define CONFIG_USE_READ_BYTE */
  

Log

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