Maybe trivial question is my first project with lwip
In my application I aded the HTTPS webserver.
webserver files are stored in SDIO card with SPI interface
I thought it was convenient to have the ability to update web pages using an FTP server
I found this and it works perfectly
https://github.com/nopnop2002/esp-idf-ftpServer
Separately activated the HTTPS web server and the FTP server are ok, however, when I enable them at the same time the transfers of the FTP server (file readings from SD) are blocked randomly and all Wifi connection (STA mode) crash.
This is a lwip debug image while reading file
I have no experience and I don't know if this suggests anything to help me understand the problem.
I also doubt that it is a trivial memory allocation problem
from Wireshark log I see a retransmission frame (after retransmission frame (14336 bytes sent) After thsi frame FTP server send two other frames but after send the scond frame it stop working
I forgot while FTP transfers files, the HTTPS server is idle with no client connected
