SDLoader allows executables to be booted from SD card, or loaded from SD card into upper 32K of a 512 EEPROM and executed, even to update itself.

Based upon Mike Green's fsrwFemto and sdspiFemto.

I can load this into my eeprom. then when I ship out my board provided the latest firmware on the included sd card with update.pgm as the file. Then since my boards will have a wireless uplink from my windows app allow my users to update firmware by transmitting my new update.pgm file to the board and since the code stays present after reset of the controller it will read the new update.pgm and write it to the eeprom. and from that point on execute the new firmware until another update.pgm file in on the card? if so I will have to say this object just saved my brain and searching for a method of updating my customers boards wirelessly without having to spend a ton of time figuring out a method.
