Fastboot issue for IMX6Q Android Kitkat 4.4 BSP

[changyuheng]

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?

Thank you!

Hi Public Account

had you attached USB cable between host PC and i.MX6 USB OTG,

as describes attached document sect.8.2 How do I use Android fastboot?

Best regards

I know~ but it works on kernel for adb mode, why u-boot fastboot mode failed?

it's no problem for pin difinition, have any ways to solve this issue?

thanks

seems Uboot does not support USB.

USB is supported only in latest Uboot releases:

version v2014.04 (L3.10.53 kernel).
