Upload failure to LilyGo T-Display VGA32_V1.4

leecliff8735 · June 5, 2025, 10:55am

I'm attempting to upload a compiled sketch to a Lilygo t-display vga32_v1.4 board.
I'm using ide 2.3.6 running on Windows 10.
The sketch compiles ok, but fails to upload. The output is below. It appears to be a problem with the syntax of the command line which executes the upload.

Any suggestions would be appreciated.


Sketch uses 917261 bytes (29%) of program storage space. Maximum is 3145728 bytes.
Global variables use 49188 bytes (15%) of dynamic memory, leaving 278492 bytes for local variables. Maximum is 327680 bytes.

Hi @leecliff8735. This error is caused by a bug in the 3rd party "esp32" boards platform:

github.com/espressif/arduino-esp32

fix(boards): Remove port property assoc. for non-unique VID/PID pairs

master ← per1234:remove-generic-port-properties-association

opened 04:46PM - 31 Aug 24 UTC

per1234

+0 -8

## Description of Change The Arduino boards platform framework allows propert…ies of a port to be [associated with a board definition](https://arduino.github.io/arduino-cli/dev/platform-specification/#properties-from-pluggable-discovery:~:text=upload_port.vid%20and%20upload_port.pid%20properties). The Arduino development software will identify a port having the associated properties as that board. This should only be done for properties that are unique to the ports produced by that board model. In cases where a board model does not produce a port with properties unique to that model, it is irresponsible to associate those properties with the board definition as this will cause other models to be inappropriately identified. The authors of these board definitions associated them with non-unique USB VID/PID pairs so those associations must be removed. The `303a:1001` VID/PID pair is of the hardware CDC serial port of the native USB ESP32 chips. The others are stock VID/PID pairs of general purpose USB to serial bridge chips that are used on many different board models. ## Tests scenarios Compile for the modified boards using the platform (at 0b8eedea5cf18e2b01f80975197b85f70a36caf3) with this patch (0a8c586953327af6d38280ca10c612a82b4d1be7) applied. ## Related links Originally reported at https://forum.arduino.cc/t/i-dont-have-elecrow-crowpanel-7-0p/1293026 - https://github.com/espressif/arduino-esp32/issues/6384 - https://github.com/espressif/arduino-esp32/issues/7292 - https://github.com/espressif/arduino-esp32/issues/9702 - https://forum.arduino.cc/t/issue-with-arduino-cloud-device-recognition-esp32-dev-module-detected-as-lilygo-t-display/1295971

The bug has already been fixed, but you are using an outdated version of the platform from before the time of the fix. Unless you have a specific reason for using this version 2.0.17, you can fix the problem by updating to the latest version of the platform. I'll provide instructions you can follow to do that:

Select Tools > Board > Boards Manager... from the Arduino IDE menus to open the "Boards Manager" view in the left side panel.
Find the "esp32" entry in the list of boards platforms.
Click the "UPDATE" button at the bottom of the entry.
Wait for the update process to finish, as indicated by a notification at the bottom right corner of the Arduino IDE window:

Successfully installed platform ...

After that, try uploading the sketch again. Hopefully this time it will work as expected.

Thank you for the response

I'm using FabGL module. The author has posted this info on github:

Warning! The latest version of the Espressif ESP32 library that FabGL runs on is 2.0.17 (or even earlier). Unfortunately, the latest versions of Espressif leave too little memory free for applications, and a project the size of FabGL can no longer function as intended.

If I use the latest version of the espresssif ESP (3.2.0), the sketch fails to compile. Here is the output:

Hi.

I did get this sketch to compile and upload. I used an older version of IDE (1.8.18) and the 2.0.17 version of the Espressif ESP32 library.

Thank you.

Warning! The latest version of the Espressif ESP32 library that FabGL runs on is 2.0.17 (or even earlier). Unfortunately, the latest versions of Espressif leave too little memory free for applications, and a project the size of FabGL can no longer function as intended.
