A fatal error occurred: No serial data received.
I have just received a new CrowPanel 5.0"-HMI ESP32 display and started to play with it but I can not upload any code to it. I always receive this error:
----> A fatal error occurred: No serial data received.
Can anyone help?
Cheers

Comments
Update: I resolved the issue by lowering the baud rate.
Hi I received the same panel, and I've a lot of problems on uploading sketches, which the most of the time fail.
When once every 10-15 times the upload works, then the serial communication fails after a few seconds. I'm trying with different usb cables. it is the same.

Sometimes it fails at the beginning, sometimes at middle transfer.
I'm trying at full baud rate and also slower boudrates and also setting the cpu at 240MHz and 180MHz.
What could cause the problem? have I bought a failed panel?
