STM32 ST-LINK Utility Command Line Interface (CLI)
e.g. -OB RDP=0 IWDG_SW=1 nRST_STOP=0 Data0=0xAA
Data1=0xBC.
This command line:
- Disables Read Protection (Level 0),
- Sets the IWDG_SW to 1,
- Sets the nRST_STOP to 0,
- Sets Data0 option byte,
- Sets Data1 option byte.
Description: This cammand configures the option bytes.
Parameters description:
RDP=<Level> : Set the Flash memory read protection
level. Level could be one of the following levels:
0 : Protection disabled.
1 : Protection enabled.
2 : Protection enabled(debug and boot in SRAM features
are DISABLED).
Note: Level 2 is available on available on STM32 F-2 and
STM32 L-1 series only.
BOR_LEV=<Level>: Set the Brownout Reset threshold level.
* For STM32 L-1 series:
0 : BOR OFF,1.45 to 1.55 V voltage range
1 : 1.69 to 1.8 V voltage range
2 : 1.94 to 2.1 V voltage range
3 : 2.3 to 2.49 V voltage range
4 : 2.54 to 2.74V voltage range
5 : 2.77 to 3.0 V voltage range
* For STM32 F-2 series:
0 : BOR OFF, 1.8 to 2.10 V voltage range
1 : 2.10 to 2.40 V voltage range
2 : 2.40 to 2.70 V voltage range
3 : 2.70 to 3.60 V voltage range
IWDG_SW=<Value>: <Value> should be be 0 or 1:
0 : Hardware independent watchdog
1 : Software independent watchdog
nRST_STOP=<Value>: <Value> should be be 0 or 1:
0 : Reset generated when CPU enters the Stop mode
1 : No reset generated.
nRST_STDBY=<Value>: <Value> should be be 0 or 1:
0 : Reset generated when CPU enters the Standby mode
1 : No reset generated.
BFB2=<Value>: <Value> should be be 0 or 1:
0 : Boot from Flash bank 2 when boot pins are set in boot
from user Flash position(default)
1 : Boot from Flash bank 1 when boot pins are set in boot
from user Flash position(default).
