Bluescreen of Death when board prints continuously to Serial Monitor

[Joko-1]

Describe the problem

A Bluescreen of Death occurs after about 30 seconds when the board is running a sketch program that causes continuous printing to Serial Monitor:

To reproduce

1. Upload a sketch that causes the board to print continuously to Serial (about every 10ms).
2. Open Serial Monitor

🐛 A BSOD occurs after about 30 s.

Expected behavior

No BSOD

Arduino IDE version

2.3.4

Operating system

Windows

Operating system version

10 22H2

Additional context

The fault does not occur when I open the serial port of the board in PuTTY.

---

Board: ESP32-WROOM-32 with CH340 Serial chip

---

Stillstandcode: DRIVER IRQL NOT. LESS OR EQUAL
Fehlerursache: CH341S64.SYS

---

I have attempted the following to solve the problem, without any success:

• Reinstalling the CH340 driver
• Updating from Arduino IDE 2.3.3 to 2.3.4
• Using another cable
• Using another Arduino sketch

Issue checklist

• I searched for previous reports in the issue tracker
• I verified the problem still occurs when using the latest nightly build
• My report contains all necessary details

Hi @Joko-1. Thanks for your report. I'm going to ask you to provide some additional information:

Please provide a simple sketch that you have verified to produce the BSOD. For example, does the BSOD occur if you upload this sketch to your board?:

void setup() {
  Serial.begin(9600);
}

void loop() {
  Serial.println("hello");
  delay(5);
}

Please also tell me which version of the CH340 driver you have installed. You can find this information by the following procedure:

1. Open the Windows Device Manager.
2. Select View > Devices by type from the Device Manager menus.
3. Open the "View" menu.
4. If there is a ✓ to the left of the "Show hidden devices" menu item, click on "Show hidden devices" to disable it.
5. Open the "Ports (COM & LPT)" section of the Device Manager tree.
6. You should see a port identified as "USB-SERIAL CH340 (COMn)" under the "Ports (COM & LPT)" section (where "COMn" is some serial port e.g., COM4). Double click on that item.
   The "USB-SERIAL CH340 (COMn) Properties" dialog will open.
7. Select the "Driver" tab of the "USB-SERIAL CH340 (COMn) Properties" dialog.

You will see the version in the "Driver Version" field of the dialog.

Please also tell me whether there is labeling on the CH340 chip on your board. If present, the labeling would look something like this:

But the chip might also be blank.

Thanks for respond,

It also happens, when I use your script.

I tested it a few times with baud rate 115200, 9600.
I didn't get the 30s as earlier (it took ~2-3min), but I noticed that it happened faster at 115200 baud.

The BSOD issue appears to stem from the CH341S64.SYS driver for the CH340 Serial chip. Here's a streamlined approach to resolve it:

• Update or Revert the CH340 Driver: Download the latest or a stable older version from wch.cn.
• Adjust Serial Communication: Reduce the baud rate (e.g., to 9600) and limit the frequency of serial prints (e.g., every 100ms or more).
• Use Alternative Serial Tools: If the Arduino IDE causes BSOD, switch to PuTTY or another terminal.
• Test Different Hardware: Use a different USB cable, port, or a board with a non-CH340 USB-to-Serial chip (e.g., CP2102).
• Update Arduino IDE: Ensure you're on the latest version to avoid IDE-specific bugs.

After this issue occurred, I tried to fix it by installing the old 2011 driver

Select "Older Windows Driver Version and Instructions"

It worked fine and stopped the BSOD
