attached is a code that emulate EEPROM with flash and output the read data

via UART to hyperterminal,

In dubug mode (Jlink), the result is as expected,

but power the PCB with MCU , it can not work, and UART seems not work after execute

/* Disable temporarily the FLASH protection on Bank 1 sector 0 */

FLASH_WritePrConfig (FLASH_B1F0,DISABLE) ;

Hi, I found out, the first Flash Erase/Program operation needs to be executed from RAM. I used the __ramfunc with IAR to execute the first write or erase from RAM. Try the same in your code, this may solve the issue.
