when I use my breakout board as usual, I found the led on the board can't work, then I found that I can't start Edison on the breakout board, but the cpu works well on the Arduino breakout board. how can I solve this problem? and I use batter(7-12v) for the power.
Are you able to access the console in the Arduino Expansion board? Since when are you experiencing this? How are you powering your Mini breakout board?
i can get into the putty console, but i can't power it up using usb line or using the battery. i use 7.4v battery and use thepin next to the usb to provide power
Have you moved the jumper in the board by any chance? When powering the board via USB, the jumper should be connected to J1. Also, could you please provide a picture of your Ports in the Device Manager after connecting the board?
Do you remember any event that could have damage the board? Where you able to use your Breakout board at some point?
