@aric1987 Why don't you create a PR for this?

@ceremcem: @aric1987 seem to be inactive by now.
I don't know yet, if his patch is still compatible with the current codebase. One needs to check.

@Ant-ON: As I believe to read from the code that these protect bits are also included in the option bytes, as the whole area is written at once. Is this correct?

[Ant-ON]

@Nightwalker-87 Yes, on F0/F1/F3:

  /* Retrieve current values */
  ret = stlink_read_debug32(sl, FLASH_OBR, &optiondata);
  if (ret) {
    return ret;
  }
  ret = stlink_read_debug32(sl, FLASH_WRPR, &protection);
  if (ret) {
    return ret;
  }
