We are pleased to announce that the ShieldBuddy add-in V1.33 is now available. It contains a new Ethernet bootloader/in system programming function. This is based loosely on the Denis Perotto Arduino MEGA bootloader and requires an Ethernet shield with the W5100 or the Boot & Work Industrial M-DUINO PLC shield.
It is possible to program the TC275 PFLASH via an Ethernet shield using TFTP. TFTP is a simple file transfer protocol which is often used to boot diskless and embedded systems. It uses UDP and requires a conventional TCP/IP network setup. The booloader is not 100% robust and if transmission and programming is interrupted, it is possible for the ShieldBuddy to be left with an incomplete or damaged application in its Pflash. If this happens, you will have to reprogram it directly from the Arduino IDE or the UDE debugger via USB.
Please refer to the ShieldBuddy user manual for more information on using it.
