Hi,
I am testing the W5x00_ftp_server.c in a W5100S-EVB-Pico, and I can't upload files to the FTP Server or edit the ones that exists there.

I can build the example, burn it on the RPI and connect through FTP with WinSCP. I can also download the test.txt file in my computer.

This is the trace I get:
--> When Download file:

--> When upload file:

--> When creating file in the FTP Server:

Also when trying to edit the new file in the FTP Server, I get connection error.

Any idea of what is happening?

Kind Regards
