ESP32C3 upload OK, won't run, IDE 2.2.1

Projects Programming
1

Hi
It's first time I try out ESP32, and IDE 2.2.1 and a lot of other things, so hopefully this is in the appropriate category.

I just got a few this ESP32C3 Dev 0.42 inch display. Pre-loaded demo works fine so no HW problems.

Using Arduino IDE 2.2.1 with the board set to "ESP32C3 Dev Module" it compiles Examples/Wifi/WifiScan just fine. Upload says all OK and last message is "Hard resetting via RTS pin..." which should mean all OK or could there be anything else wrong?

I have tried with two boards and uploads goes fine but no running code.

A strange thing is that when going "Tools/Get Board Info" it says "BN: ESP32-S3-Box" which I guess is just an un-updated entry. The "SN:" matches what I see with dmesg. I did however tried to change the board to "ESP32 S3" but would not upload at all.

I tried to hold down "boot" button while connecting USB-C and upload, and then release the boot button with the same result. No output in the Serial Monitor connected. Changing baud to 9600 didn't help either.

I tried other small demos without luck.

Any idea to where to look next?

best regards

Welcome back

So you basically don't have a problem with the IDE :wink: And you also don't seem to have a problem with your board.

That information should be pulled from the board as far as I know.

That indicates that you did select the wrong board.

Question is why you think that there is a problem. What are the symptoms? If it's only about the upload, I would keep the board at "ESP32C3 Dev Module".

The platform author can associate a board definition with identifying information from the port. If there is a board definition associated with the port, the board name is shown in this "Board Info" dialog.

Although any arbitrary identification properties are supported by the Arduino platform framework, most platforms use the USB VID/PID identifier pair. The USB interface of the ESP32-C3 and ESP32-S3 microcontrollers have a default VID/PID of 303a:1001, which is provided by the manufacturer Espressif.

Typically in this case where a property is not uniquely identifying, the platform would not associate it with the board. For example, Arduino does not associate the 0403:6001 VID/PID pair supplied by FTDI for the FT232R chip with definition of the classic Nano board because this would cause the ports of other boards using the FT232R to be incorrectly associated with the Nano board definition in Arduino IDE.

But there is nothing in the Arduino boards platform framework to prevent each platform author from associating non-unique properties with their board definitions. That is what the ESP32 boards platform developers did. They associated many different board definitions with the VID/PID pair 303a:1001. For example:

... and so on.

So it is not clear what Arduino IDE should do in this case. It just picks the name of one of the multiple associated boards to show in the dialog and other parts of the Arduino IDE UI. Apparently there is some non-deterministic behavior in terms of which board Arduino IDE 2.x selects, so you might see the name change.

Here is the link for the library to use to control the screen on that board.

What ESP32 URL in "Additional Boards Manager" do you have in the preferences?

5

The problem is that I get no serial output from the esp32.
When trying to use WifiScan.ino it should at least write "Setup done" and "Scan start" in the serial monitor but I get no messages.

It also seems like the upload work just fine without pressing the boot button.

I also tried the simple ws2812 LED demo without luck. Well, it is more complicated than just turning on a LED.

Current conclusion:

  1. Device is attached
  2. Upload working
  3. Ampere supplied is adequate
  4. The right board/compiler is selected

I'm not really sure what to try next...

You've got the library in post #4?

Sorry to say....But this won't work, the display is OLED to start with. :upside_down_face:

Yes, from File -> Preferences:

Yes, display is this one 0.42 inch OLED Bare Display (72x40, SSD1306).
Not LCD.

12

Have you tried swapping the I2C pins around?

I2C pins are 5(SCL) & 6(SDA) by default.

13

When first powered on the device was actually working.
It was showing the demo which can be seen here.

So the hardware is correct.

So when it's not working, I guess it must be:

  1. Compiled to wrong machine code (but it seems right in the log)
  2. The code is written to a wrong memory address in the chip (could that happen?)

I have tried to setup Espressif-IDE instead but it's not working yet. I guess that it wouldn't help anyway if the problem is compiling for the wrong machine architecture.

14

I guess you are still getting confused by the board's port being identified as "ESP32-S3-Box". If you are interested in the boring details of why that happens, I explained it already in my previous reply (post #3), but all you really need to know is that it doesn't indicate any problem and won't cause any problem so you should simply ignore the incorrect board name shown in that "Board Info dialog and the Tools > Port menu.

As long as you have the correct board selected from the Tools > Board menu in Arduino IDE, everything is fine. As you already discovered, the tool that uploads the sketch is even smart enough to check whether the board has a different microcontroller than the one you have selected in the IDE and fails the upload.

Solved 1!

Problem: A lot of demos didn't work.

Solution: Start with a simple example like ASCIITable.

I thought WifiScan was a simple example which could just run anyway but it got stuck at WiFi.mode(WIFI_STA); so no message was printed out. Maybe I should report this as a bug?

Solved 2!

Problem: Within "Arduino IDE 2.2.1" I was using the board "esp32 by Espressif Systems 3.0.0-alpha2" which was the default.

Solution: Downgrade board to "esp32 by Espressif Systems 2.0.14"

The board used: ESP32C2 Dev Module

Sorry for the inconvenience.

No problem.... :slightly_smiling_face:

I have the same setup, and want to add that the ESP32-C3 goes into a boot loop with this message on serial output, at least with the 3.0.0-rc1 and 3.0.0-rc2 releases specified by the product's github examples. This message below may be useful to those searching for this condition.

-> assert failed: i2c_ll_cal_bus_clk /IDF/components/hal/esp32c3/include/hal/i2c_ll.h:105 (clk_cal->scl_wait_high < clk_cal->sda_sample && clk_cal->sda_sample < clk_cal->scl_high)

The Espressif 2.0 board version boots fine, and enabling "USB CDC on Boot: Enable" in IDE Tools menu fixed the printing.

Have same problem with board ESP32-C3-0.42 OLED
it detects as:

BN: ESP32S3 CAM LCD
VID: 0x303a
PID: 0x1001
SN: A0:76:4E:18:FA:34

When i choise in Arduino IDE board: "ESP32S3 CAM LCD" after compiling I got message:

esptool.py v4.6

Connecting...

A fatal error occurred: This chip is ESP32-C3 not ESP32-S3. Wrong --chip argument?
Failed uploading: uploading error: exit status 2

After choising in Arduino IDE board: "ESP32C3 Dev Module", it compiling without errors and uploads without errors.
But when I reset board, it repeatly rebooting... in Serial console it prints next debug:

Looks like I didn't read carefully this topic. Sorry...
After removing esp32 by Espressif Systems v3.0.0, and install v2.0.14, problems is gone.
My programs (and Hello world) uploads correctly.
Thank you! :heart_eyes:
