Hi
I am used to programming chip's firmware through a JTAG or programming port. So one is asking me to update firmware through a WIFI port. Is this possible? I assume it is because routers update their firmware through WIFI.

 

Sure it's possible. In either case, you are merely communicating with a device and then that device uses that communication to write data to some kind of memory. NASA and others reprogram spacecraft from millions and billions of miles away using radio signals. Your board just has to be designed to allow this.

 

What do I do to set up an ARM 4 processor to be flash through the WIFI interface. Is there a chip set for this application?
