Hi,
I am trying lock a portion of Flash memory using WRP(Write Protection). when I am configuring the Option bytes for WRP. I am using STM32L443VC MCU and I have multiple questions:
1. Which area to select WRPAreaA or WRPAreaB for page 0 to page 11 because there is no division of area given?
2. I am trying to lock from page 0 to page 11 in the flash memory but I am seeing different values even after OBL launch:
example: WRPStartOffset = 0x80 (Expected: 0x00)
WRPEndoffset = 0x0B (Expected: 0x0B)
This is because in the reference manual I see FLASH_WRP1AR reset value is 0xFFXX FFXX and in the register value is 0xFF00 FFFF. If I use Register value got 0xFF0B FF80 instead of 0xFF0B FF00. if I assume 0xFF00 FF00 i am getting 0xFF0BFF00. Even I tried for different page offset still I am seeing Startoffset value different. Please check the attached snapshots for your reference.
3. I am using segger jlink to flash the code and Please let me know how to flash using jlink for option bytes.
Please find the attached documents for your reference.
