EA7013 ESP32 RGB 7" display, serial isn't working

[wolfrose]

Hi,

I bought this display from aliexpress, I got it to work with ESP IDF, and also in arduino ide but now it's still identified by arduino com port but the serial isn't working.

1. On arduino ide, it's identified as "ESP32S3 dev module"

2. On windows device manager, it's identified as "USB serial device"

When I want to program it on arduino ide, it gives this error:

Arduino: 1.8.19 (Windows 10), Board: "ESP32S3 Dev Module, Disabled, OPI PSRAM, QIO 80MHz, 4MB (32Mb), Core 1, Core 1, Hardware CDC and JTAG, Disabled, Disabled, Disabled, UART0 / Hardware CDC, Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), 240MHz (WiFi), 921600, None, Disabled"

A serial exception error occurred: Write timeout

Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

 does not exist or your board is not connected

Invalid library found in D:\Programs_Files\Arduino\libraries\arduino-esp32-master: no headers files (.h) found in D:\Programs_Files\Arduino\libraries\arduino-esp32-master

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

• Any suggestions of how to re-flash it or get the serial to work again ?
• Also the one I have doesn't have "boot" button, which I think might have solved my problem.

Remove devices. Restart IDE. Insert devices.

It worked eventually.

I had to pull IO0 to GND. As there's no boot button, and so this way I was able to get the ESP32 into boot mode and hence, the programming process succeeded.
