We are developing our android project base on imx6sl 4.4.3 platform.
in our project, we use emmc instead of sdcard in imx6sl demo board.and use mfgtool for the firmware updating.
the mfgtool stop at "No Device connected" after "start" pressed.
if I disconnect the usb, then connect the usb ; the PC will recognize the device, the console will print the log "g_mass_storage gadget:high-speed config #1:Linux File-Backed Storage", and the mfgtool will start the firmware updating.
for the firmware updating processing, everything works fine except I have to re-connect the usb for each updating.
do you have any idea about how to fix this re-connect usb issue?
