Hello, iam martin.

I have the problem, that i couldnt upload somethink to to lilygo t-display s3.

I installed everythink simular like this git repository (also the eSPI lib manual in PlatformIO for the tft example) and the first uploads work without problems.

Now, after connect a BME280 Sensor to SPI/I2C and install BME280 lib from adafruit, i couldnt upload anythink.

The ERROR Message is: A fatal error occurred: Failed to connect to ESP32-S3: No serial data received.

What can i do? I tried to put the t-display to bootmode, but i dont know if i did i right. I changed also the usb port, press the reset button and so on, but nothing worked.

Many thanks -Martin error

You need to manually enter BOOT mode to upload. The operation is to press and hold the BOT button after connecting the USB, and then click the reset button. It doesn't do anything after the operation is complete. The screen stays black.

Thanks so much Micky, that helped!

If you still have problems, please open it again

dear all, I have a similar problem. I managed to enter in BOOT mode holding the boot button while swithing on the device. After that, the COM port changed and, selecting the new COM port, I managed to upload a custom firmware (very simple). However, after the upload phase is finished, the device does not execute the fw. The screen is black. The COM port is still the one used to upload. Is there a way to exist the BOOT mode or this is done right after uploading a fw ? Any suggestion? Thanks

Occasionally, after I upload a sketch the new program will not run after the upload is successfully completed. The 'fix' is to try pressing the little black 'reset' button on the side. Failing that, there is a provision in the design whereby you simply unplug it from USB or battery and plug it back in. This does not happen every time, but mostly when I am testing 'extreme' applications like the Bosch BNO085, or dual cores or some other.
Turn on your serial monitor and see if the ESP32 is 'crashing and re-booting'. -Terry

Dear @teastainGit thanks for your message. However, I have a different behavior. Below my problem:

ESP-ROM:esp32s3-20210327 Build:Mar 27 2021 rst:0x15 (USB_UART_CHIP_RESET),boot:0x2b (SPI_FAST_FLASH_BOOT) Saved PC:0x4201d546 SPIWP:0xee mode:DIO, clock div:1 load:0x3fce3808,len:0x44c load:0x403c9700,len:0xbd8 load:0x403cc700,len:0x2a80 entry 0x403c98d0

I also noticed that if I switch off and on the device WITHOUT pressing the boot botton, then I cannot see the device on the web (no COM port or /dev/tty port assigned)... Any idea on how to restore the device so that to execute a custom fw?

Hi michelegirolami I am most familiar with LilyGO T-Display S3 (this repository) and not with meshtastic, which sounds cool. The standard technique for getting into program transfer mode on LilyGO ESP32 S3 boards is, as you may know, Hold down Boot, while pressing boot, press and release Reset, then release boot. in that order. Alternately press and hold boot while plugging in the USB cable. If you can see the port, download your meshtastic and when finished you may see (in Arduino IDE ) the message " Leaving... Hard resetting via RTS pin..." If the new firmware does not start, try unplugging and plugging in again. You might try raising an Issue over on your products GitHub repository: https://github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/issues -Terry
