Interface with FS
µC/TFTPs requires the presence of a file system. As mentioned in section Getting Started, the example application uses µC/FS.
All Micriµm network applications that require a File System (FTP, TFTP, HTTP, etc) use the FS abstraction layer interface present in net_fs.h
inside the FS folder of µC/TCP-IP (see TCPIP Network File System Abstraction Layer). Also, in this folder, a port for the µC/FS-V4 File System is giving and template files to help you port other File Systems if needed.
