I tried update image by fastboot on IMX6 custom board (refer to sabresd board), but something was wrong at first step,
I can't connect to device and error message as following:
|MX6Q SABRESD U-Boot > fastboot|
|fastboot is in init......flash target is MMC:2|
wait usb cable into the connector!
Correct me if I'm wrong,
I think the pin definition should be modified,
but I don't know which pin?
