Simple LED blink on lora-e5 mini

[kargarisaac]

Hello,

I'm trying to use this repo to program a new lora-e5 mini board that I got recently, but cannot program the board. So, I decided to just test a simple LED blink test. Again, I cannot do it and get the same error. This is the error I get:

I create a new empty project and set portB pin5 on and off as follows:

while (1)
  {
      HAL_GPIO_WritePin(GPIOB, GPIO_PIN_5, GPIO_PIN_SET);
      HAL_Delay(1000);
      HAL_GPIO_WritePin(GPIOB, GPIO_PIN_5, GPIO_PIN_RESET);
      HAL_Delay(1000);
    /* USER CODE END WHILE */

    /* USER CODE BEGIN 3 */
  }
  /* USER CODE END 3 */

Any idea?

I also tried to use stm32cubeProgrammer but it didn't help:

Hello @kargarisaac,

Have you set the "Read Out Protection" to AA inside STM32CubeProgrammer as mentioned in the README?

I try to do it but it doesn't work always. It gives me the following error. I could do it once, but again it didn't work either.

I also see the "unlock chip" and when I try it, I get the following error:

Any idea? I'm trying to solve this for more than a week but no result yet. Any help would be appreciated.

Thanks

Hi,

Change RDP to AA and press Apply. This works for me.
