The user application can use the TFTP-server service to download and upload files from/to a remote TFTP client.
Current version of the TFTP server supports maximum of one simultaneously connected TFTP clients.
After the TFTP server is initialized by calling the fnet_tftp_srv_init() function, the user application should call the main service-polling function fnet_service_poll() periodically in the background.
For the TFTP-server service example, refer to the FNET Bootloader source code.

Prototype of the TFTP-server callback function prototype that is called when the TFTP server has received a new data packet (request_type equals to FNET_TFTP_REQUEST_WRITE). This callback function is also called when the TFTP server is ready to send a new data packet to the TFTP client (request_type equals to FNET_TFTP_REQUEST_READ). More... | |

| Prototype of the TFTP-server callback function that is called when the TFTP server has completed file data transfer. More... | |
| typedef long | fnet_tftp_srv_desc_t |
| TFTP server descriptor. More... | |

| TFTP server states. Used mainly for debugging purposes. More... | |
Functions | |
| fnet_tftp_srv_desc_t | fnet_tftp_srv_init (fnet_tftp_srv_params_t *params) |
| Initializes the TFTP-server service. More... | |
