Suggestions for using external flash SPI

Hi Suprazz,
I’m Frederic, living in France,
First of all, happy new year and all the best to you and all the readers of my reply!
I’m struggling for days to find a way to upload files to an external chip (W25Q64) using an FTP server.
It seems that you managed to do that.
I’m quite new with C++ code, and i’m moving forward on my projects doing test/error/test/error…so moving really slowly and i’m totally blocked today.
I can create the FTP server, and i can access to the Internal memory of my ESP32-S3.
I then use an FTP client (FileZilla) and i can drag and drop files. It works perfectly.
But what i would like to do is exactly the same, but with an external chip, connected to MISO/MOSI/SCK/CS to pins to my ESP32.
Do you think you can share your code so i can see how you managed that?
Thanks a million in advance for your time and skills,
Frederic.

@fepalmytho, this is a forum for Particle device users, which are based on different processors and firmware since they have a DeviceOS. You should look on Espressif or Arduino ESP32 Core forums (depending on how you are creating your firmware) for solutions.

Hi, thanks a lot for your prompt answer.
I gave a try on your forum, as i did’nt find any solution on the other specific forums.
Thanks anyway,
Regards,
Frédéric.
