Erase exit with error

[creatron]

uint8_t erase_flash (void), exit with a timeout, but the program still manages to program the chip.

The erase_flash return status is ignored, thus the error is 'not visible.

I changed the function to log the error on the serial terminal. I always get timeout 2, even if the timeout is 1 sec.

  uint8_t erase_flash (void)
  {
  gprintf ("\r\n Erasing flash.. please wait ..");
  write_register(0x4001e504, 2);

  long timeout = millis();
  while (read_register(0x4001e400) != 1)
  {
  if (millis()-timeout > TIMEOUT)
  {
  gprintf ( "\r\n Erasing timeout 1 ..");
  return 1;
  }
  }

  write_register(0x4001e50c, 1);

  timeout = millis();
  while (read_register(0x4001e400) != 1)
  {
  if(millis()-timeout > TIMEOUT)
  {
  gprintf ( "\r\n Erasing timeout 2...");
  return 1;
  }
  }
  write_register(0x4001e504, 0);
  timeout = millis();
  while (read_register(0x4001e400) != 1)
  {
  if(millis()-timeout > TIMEOUT)
  {
  gprintf ("\r\n Erasing timeout 3...");
  return 1;
  }
  }
  gprintf ( "\r\n Erasing done ..");
  return 0;
  }
