we have succeed in eim multiplexed mode , but for some reason we have to use eim non-multiplexed mode. we use csi camera ,so csi0 pins can not be used as eim_data[0:15] , so for data bus ,we have not choice but use eim_data[16:31]. But i find that some of those pads are use for usb otg and usb otg is used to flash uImage ,fs and so on. Does it influence eim data bus if we dont change configure because after flash we do not use usb otg any more, or does it mean that we have to disable usb otg after we flashed uImage? i can not try it now, so i have to ask anyone who know the answer.
