Description

Hello!
I'm trying to use and libraries in same project. However when I use SPIFFS.begin(); and server.handleClient(); I get error while uploding. It takes 5 minutes to upload to 99% and than error! If i upload program without SPIFFS.begin(); it uploads fine. Code and debug messages are below. I hope that someone can help me.

Also I have another issue. Code is uploading very slow. It takes like 5 minutes to upload simple code like this. I am wondering if this is normal.

Kind regards,

You can Increase the upload speed from menu>>tools>>upload speed>> 256000
It will significantly reduce upload time.
You can also choose greater speed but it may produce an error.

Thank you, this realy increases upload speed :D
Any idea why i get this error?

[Gromblisk]

woohoooo! It seems higher upload speed also solved my problem! It uploads code fine!

Thank you very much :D

Welcome!

9600 was likely causing a timeout somewhere.
Closing as resolved.

Hi,
Thank you, i was trying at 9600 or 115200 and i always got the same error.
I switched to 57600 and the upload works fine.

Same problem was with me , Just change uploading speed to 115200 or higher.
