My boron has the breathing magenta LED after flashing it, but it has the wrong program in it. I compile and flash the program to the device and everything appears to go fine. however, the chip is never erased. It always has the previous program on it. I tried a hard reset and ended up with the flashing blue light. I then reconnected it to my account, but the same thing happens. I cannot flash another program to the device.
Well, I don’t honestly know what it was that fixed it. I tried all sorts of things. I ended up changing the OS from 3.1 to 2.2. After that things seemed to work again. I have no idea which OS I should be using or even how to decide which one is best.
