The µC/TFTPs module has to be configured according to your specific needs. A template configuration file (tftp-s_cfg.h) is included in the module package (see section Directories and Files), and this configuration should be copied into your application directory and included to your project. Here is the list of the values and description of each of the configuration variable. However, keep in mind that future releases of this module might include more configuration options.
#define TFTPs_CFG_IPPORT 69
Defines the UDP port µC/TFTPs will receive requests on. The default value (69) is the one specified in RFC #1350.
#define TFTPs_CFG_MAX_RX_TIMEOUT_MS 5000
#define TFTPs_CFG_MAX_TX_TIMEOUT_MS 5000
Define the maximum receive and transmit timeouts in milliseconds.
#define TFTPs_TRACE_HIST_SIZE
Define the maximum number of trace items to keep in memory.
