FTP Server Example

FreeRTOS-Plus-TCP and FreeRTOS-Plus-FAT Examples

Note: This demo has a dependency on the FreeRTOS-Plus-FAT code base and is therefore currently only available in the FreeRTOS Labs download.

Not all demo projects will include this example. If this example is included in a demo project then it may be necessary to set mainCREATE_FTP_SERVER to 1 at the top of the project's main.c source file to include the example in the build.

This example uses FreeRTOS-Plus-TCP to implement an FTP server that accesses files from a file system implemented by FreeRTOS-Plus-FAT. Some demo projects store files on a RAM disk, while others store files on non-volatile media such as an SD card. Some projects even mount both a RAM disk and an SD card within the same virtual file system.

If an example uses a RAM disk then a set of example files are created on the RAM disk after it is mounted.

NOTE: Performance will be limited when using the FreeRTOS Windows port.

The FTP server can be accessed using a standard FTP client, such as FileZillaexternal_link. To connect:

  • Enter the IP address or hostname of the FTP server as the host (the FTP server is the target running FreeRTOS-Plus-TCP).
  • Enter "anonymous" as the username.
  • Leave the password blank.
