mfgtool (android) for emmc

[lukeli]

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?

Hi luke

is it working with sd card and default images

Also one can check signal EPDC_PWRCOM (USBOTG1_ID)  on i.MX6SL EVK
schematic spf-27452 is high or floating and if processor VDD_USB_CAP is powered.

Just for test one can try with another board or with additional usb hub.

Best regards
igor
