Question
STM32 readout protection (level 1)
Posted on June 15, 2012 at 08:55
Hi,
when I enable the readout protection (level 1) using stm32-stlink-utility, I can't write anymore on the eeprom. if I try to disable the readout protection (level 0) using stm32-stlink-utility, it works perfectly. I'm using this software sequence,and it works perfectly without the readout protection enabled.DATA_EEPROM_Unlock();DATA_EEPROM_FixedTimeProgramCmd(ENABLE);
DATA_EEPROM_ProgramByte(Address,data);
DATA_EEPROM_FixedTimeProgramCmd(DISABLE);
DATA_EEPROM_Lock();
How Can I solve this issue ? I'm using: Windows 7 64bit st link utility 2.2.0 target mcu: STM32L152V8T6 Vdd: about 2,4Vdc regards
