* 21.Example TFTP client + SD card FATFS (for reading and saving a file from PC TFTP server).
** After pressing the SW1 button, it reads the “readme.txt” file from the PC TFTP server and saves it on the SD card.
* Then prints out it contents head in a serial terminal.
* TODO:
* OK(v1.1) 1. Print-out received file from TFTP to serial console (small file < 512 bytes OK).
* OK(v1.2) 2. Print-out received file from TFTP to serial console (multi-packet files > 512 bytes).
* OK(v1.3) 3. Write-in data to SD-card file "test.txt" and another patterns.
* OK(v1.4) 4. Print out "test.txt" contents head (from SD-Card ) in a serial terminal.
* 5. Add handlers for CHK_RAM_LEAKAGE && CHK_UPTIME.
* 6.?? Clear the code from the loopback sockets (Is it really need to do?)
*
* Remark:
* Checked with PC tftp-server (WIN7) - tftpd64.exe
