Nano esp32 IDE problem uploading sketch

swordfish45 · November 19, 2024, 5:06pm

Recently purchase a nano-esp32. I installed Micropython and tried a few examples. I decided to switch back to Arduino IDE and followed procedure to Reset the Arduino bootloader on the Nano ESP32.
I did not get Leaving...Hard resetting via RTS pin...
Following is verbose output:

FQBN: esp32:esp32:nano_nora

Have been working on this for two days and have tried many suggestions. Still can't upload a sketch.

Vague memory. It's DFU, drag and drop the DFU fie to the NANO ESP32.

swordfish45 · November 19, 2024, 7:00pm

The nano esp32 is connected to USB port. Ho do I drag and drop to USB port?

sonofcy · November 19, 2024, 7:17pm

Like I said, it's a vague memory. If you have a Win or Mac, then you drop on the object in the file mgr that represents the USB port. I do NOT recall where the DFU file is located though.
Try this https://youtu.be/YGQgSoN9t6w?si=nRrMU-sVPr-ScuNU
Make sure you have selected the Arduino board not the Espressif board.

sumguy · November 19, 2024, 7:56pm

@swordfish45 take a look at this thread in particular the post made by @ptillisch.

check the com port number at every step because it is very possible that it will change during the process of changing firmware.

If that does not work detail the steps you took trying to get back to the Arduino firmware

swordfish45 · November 19, 2024, 8:13pm

Thanks for the reply. Didn't work. I have tried similar suggestions with no good result.

lburelli · November 20, 2024, 9:02am

Please try again the bootloader update, following the instructions VERY CAREFULLY.

The fact that you get "No DFU device" while following that guide means that you did not do one of those two things:

select "Esptool" in the Tools > Programmer menu (make sure there is a check on the only option there), or
click on Upload using Programmer from the Sketch menu (not the upload icon).

Good luck!

I do now get DFU util and can upload using Programmer. But I still cannot do a normal upload from the IDE.
I looked at the boards.txt for Arduino nano esp32 and it looks like the DFU is the only way to upload.
Also if I switch to using the esp32 core I do not get the full esp32 tools menu i.e. I only have two partitions to choose from.
I don't think I can do OTA updates with this configuration.
Any ideas on how to do a normal Arduino upload on the nano esp32??

swordfish45 · November 20, 2024, 10:46pm

Back at it this afternoon. Now I installed Micropython and opened Arduino Lab. Ran a few prints. Everything fine there.

So switched back to Arduino IDE as per instructions in the Micropython docs.
I uploaded a sketch using esptool and programmer as per previous instructions at VERY CAREFULLY (note I've done this at least 15 times in the past three days).
The upload was successful but I had no output on Serial monitor. I pressed the reset button and no Serial output. I removed and reinserted the USB cable and still no Serial output (Note: I have changed the cable a number of times as well).
So the Sketch was uploaded indicated by the previous blink sketch was no longer blinking.
Seems to be something wrong with communication between the nano esp32 and the COM port. I have a number of ESP32 dev boards which have given me no problems with COM port issues.
Googling issues with NANO ESP32 I have found a number of people had very similar problems with this board.

Any ideas, suggestions?? I will try anything.

Your first post mentioned trying to reload the bootloader unsuccessfully due to "No DFU device". Then you said it did "still cannot do a normal upload from the IDE". Now the issue is that the Serial output is not working.

Trying my best to understand the issue, but I am confused.
Please always use the latest Arduino ESP32 Boards core in your tests.

After updating the bootloader, are you able to do "normal uploads" (i.e. via the Upload button on the toolbar)? If not, can you describe the issue?
Can you post the sketch you expect to have serial output from? You can also verify Serial functionality with the "DigitalReadSerial" example sketch.

swordfish45 · November 21, 2024, 1:39pm

Sorry, no serial output also meant no normal Upload via Upload button on toolbar. After uploading using programmer I do get serial prints. If I then press reset button or remove and re-insert USB cable the COM port number changes and I get no output at all.
I used several sketches but the simplest one was a modified blink sketch to blink LED while also printing in the loop section. This code:

//#define LED_BUILTIN 2

void setup() {
  Serial.begin(115200);
  pinMode(LED_BUILTIN, OUTPUT);  // Initialize the LED_BUILTIN pin as an output
  Serial.println("Setup done");
}

// the loop function runs over and over again forever
void loop() {
  Serial.println("LED ON");
  digitalWrite(LED_BUILTIN, LOW);  // Turn the LED on (Note that LOW is the voltage level
  // but actually the LED is on; this is because
  // it is active low on the ESP-01)
  delay(1000);  // Wait for a second
  Serial.println("LED OFF");
  digitalWrite(LED_BUILTIN, HIGH);  // Turn the LED off by making the voltage HIGH
  delay(1000);                      // Wait for two seconds (to demonstrate the active low LED)
}

Thanks for the explanation. I have already heard something like this, but I wasn't able to replicate it here, so I'm kind of lost.

I would like to get some context:

~~Is this on Windows, or another OS?~~ Scratch that, yep, that's in the first post
Is your RGB led flashing at RESET / power up? Can you enter the bootloader by pressing RESET twice (but not too fast...)? You should get a slowly fading LED, and this mode should allow normal Upload.
What core version have you been using? There are at least 3 Arduino ESP32 Boards packages (2.0.13, 2.0.18-20240930-arduino3 and the latest 2.0.18-arduino.5). Can you try if this issue affects all of them?

Thanks in advance for your help!

swordfish45 · November 21, 2024, 2:51pm

After reset/power up RGB LED flashes once and then nothing.
I also get this output while doing normal upload after pressing reset twice:

Done!

I am using latest Arduino ESP32 Boards 2.0.13 , 2.0.18-20240930-arduino3.
I do not see latest '2.0.18-arduino.5' in the dropdown menu.

swordfish45 · November 21, 2024, 3:26pm

At this moment I am seeing, in the serial monitor, an update to 2018-arduino.5. Seems to be taking forever. I will do some tests when it is done.

lburelli · November 21, 2024, 3:36pm

That is entirely normal (but I guess still no output?).

Can you confirm you tried both?
The current version is the one in green just after "by Arduino" in this picture:

Thanks!

swordfish45 · November 21, 2024, 3:52pm

Within the last five minutes version 2.0.18-arduino.5 was automatically installed.
I have done a couple of tests, one with the Blink-Print sketch and one with reference to an ESP32 library. In both cases i did a normal upload without pressing the reset button twice.
I then switched the board to esp32 mode and tried to compile a large ESP32 sketch I have been working on and it fails. I compiled this sketch on another esp32 dev board and had to select HUGE partition to compile.
With the nano esp32 I cannot select that partition which , I think, is why it fails. This must be a problem between the nano esp32 and the esp32 core 3.0.7.
I purchased the nano esp32 to use with this sketch.

lburelli · November 21, 2024, 4:18pm

Does that mean that you have no issues with 2.0.18-arduino.5? Not even the missing Serial output?

I guess "switched the board to esp32 mode" means you are now using the esp32 core 3.x from Espressif. Still, what other ESP32 board did you develop for?

The "Huge app" partition does not support OTA, and is therefore not compatible with our idea of the "Arduino Nano ESP32" product, so we will not support it. Also, we have not yet validated any of the 3.x cores for use with the Nano ESP32.

That said, your Nano board has an ESP32-S3 CPU at the core and so there is nothing preventing you from choosing the ESP32-S3 Dev Module board in the esp32 package. You will be able to use the memory on the CPU as you wish, but you will lose all Arduino features (double tap recovery, pin numbering, DFU, OTA) and be forced to always upload with the same B1+GND procedure as the bootloader update.

swordfish45 · November 21, 2024, 4:31pm

Yes, I did mean using the esp32 core 3.x.
The other board was a ESP32 WROVER with partition set to HIGH and the sketch uses references to ledcAttach().

swordfish45 · November 21, 2024, 4:45pm

Sorry, I missed your reference to ESP32-S3 Dev Module. It seems to have another error compiling the sketch with HUGE partition.
I am not going into that. I will just use the nano esp32 for smaller projects with board set to Arduino NANO ESP32.
The new nano esp32 board update has fixed my original problem, including serial output, so consider this closed and thanks for your help.
