esp32Display 7 inch error when upload code
Hello,
I want to start a new project to install this fantastic screen on our machines, but I have not been able to complete even the first step.
I follow the tutorials but when I try to upload the code to de elecrow fails with that message:
Sketch uses 262017 bytes (19%) of program storage space. Maximum is 1310720 bytes.
Global variables use 18540 bytes (5%) of dynamic memory, leaving 309140 bytes for local variables. Maximum is 327680 bytes.
esptool.py v4.5.1
Serial port /dev/ttyUSB0
Connecting.....
Chip is ESP32-S3 (revision v0.2)
Features: WiFi, BLE
Crystal is 40MHz
MAC: 74:4d:bd:9d:9d:a8
Uploading stub...
Running stub...
Stub running...
Changing baud rate to 921600
Changed.
A fatal error occurred: Unable to verify flash chip connection (No serial data received.).
Failed uploading: uploading error: exit status 2
I try to put in boot mode with press boot and reset but no changes the error continues.
Apparently the screen is connected as it is detected by the Arduino IDE.
I work with Linux18.04.
Any help will be welcome
Regards,
Enric

I try to follow the instructions in W10 and works fine. Then it's something related to Ubuntu 18.04. Maybe some permissions.
Any help?
Hello @eperezat ,
May I kindly ask when working on Linux, which version of the esp32 package do you install?
