I have two 5V16Mhz Pro Micros that worked fine with the arduino IDE version 1.0, I want to use the latest version of the IDE (1.0.5) but I understand that I need to burn a new boot loader for this to work – is this correct?
I have tried installing the latest bootloader from the add on files following this https://www.sparkfun.com/tutorials/338 tutorial and using my arduino Ethernet as an isp – using both the avrdude command line method and from within the IDE – both approaches complete successfully but when I reset the board the yellow led does not flash which seems to indicate there is no bootloader.
I also tried burning the diskloader bootloader from the bottom of this thread https://forum.sparkfun.com/viewtopic.php?f=32&t=32149 with the same result.
If I burn blink to the board via the arduino Ethernet as an isp both the green and yellow leads light up but the blink program does not run – but it does prove the programmer is doing something to the pro micro.
What am I doing wrong?
