I have the now-discontinued SF arduino ethernet pro https://www.sparkfun.com/products/10536 and seem to be having the issues described at http://arduino.cc/blog/2011/01/20/issue … d-edition/. The board will happily run sketches when they are uploaded, but if I remove it from power it just infinitely flashes the led as if no sketch.
I’ve tried searching multiple forums to find a solution to this, but I’ve either been looking for the wrong terms or just couldn’t find it. From everything I have found, I just need to update the bootloader. Easy enough, except that I can’t seem to do it. I’ve tried a few different ways of getting it on there. I’ve read http://www.sparkfun.com/tutorials/247, http://arduino.cc/en/Tutorial/ArduinoISP, http://scuola.arduino.cc/en/content/upg … st-version but none of the different methods have worked. They all result in “programmer not responding.” I’m trying to use an Arduino Mega to do the programming, as that’s all I have.
I found a solder jumper on the bottom of the board labeled PROG and tried all the linked steps with that shorted, but no change.
I have a project that I’d like to use this board for, and have all the coding done, but if it won’t load the sketch after it loses power, it’s rather useless. I’m hoping somebody has this board and has experience reflashing a new boot loader onto it. Can anybody give me some tips on what step(s) I’m missing?
