User Configuration:
nBOOT0 : 0x1 (nBOOT0=1)
nBOOT1 : 0x1 ()
nSWBOOT0 : 0x1 (BOOT0 taken from PH3/BOOT0 pin)
SRAM_RST : 0x1 (SRAM1 and SRAM2 are not erased when a system reset occurs)
SRAM2_PE : 0x1 (SRAM2 parity check disable)
nRST_STOP : 0x1 (No reset generated when entering the Stop mode)
nRST_STDBY : 0x1 (No reset generated when entering the Standby mode)
nRST_SHDW : 0x1 (No reset generated when entering the Shutdown mode)
WWDG_SW : 0x1 (Software window watchdog)
IWGD_STDBY : 0x1 (Independent watchdog counter running in Standby mode)

Security Configuration Option bytes ESE:
ESE : 0x0 (Security disabled)
PCROP Protection:
PCROP1A_STRT : 0xFF (0x803FC00)
PCROP1A_END : 0x0 (0x8000000)
PCROP_RDP : 0x1 (PCROP zone is erased when RDP is decreased)
PCROP1B_STRT : 0xFF (0x803FC00)
PCROP1B_END : 0x0 (0x8000000)
Write Protection:
WRP1A_STRT : 0x0 (0x8000000)
WRP1A_END : 0x1 (0x8000800)
WRP1B_STRT : 0x7F (0x803F800)
WRP1B_END : 0x0 (0x8000000)
OPTION BYTES BANK: 1
Q.: I cannot start my own program at 0x8000000
How can I remove write protection? or possibly to another Addr. move
Q.: Is there a chance to start my own program on this board?
