How to handle issue on “Waiting for devices” when downloading android images to i.MX8MQ MEK via UUU Tools

Descriptions on the issue:

  1. running “uuu uuu-android-mx8mq-evk-emmc.lst

No any problem, downloading images is OK.

  1. running “uuu_imx_android_flash.bat -f imx8mq -a -e

Below lines will be showed on windows console:

flash the file of u-boot-imx8mq.imx to the partition of bootloader0

<waiting for any devices>

            Then downloading operation stopped.

------------------------------------------------------------------------

                In order to help uses save development time, I tested above 2 commands for downloading images on windows 7 64bit and windows 10 64bit respectively.

                Below is detailed steps for the operation:

  1. Hardware Preparations

(1) Switch SW802 on i.MX8MQ EMEK, set 1-4 off, 2-3 on

i.MX8MQ is at usb serial download mode.

(2) Connecting J1701 to PC USB by a USB OTG cable.

(3) Connecting J901(usb type c) to PC USB by a USB 3.0 cable.

(4) Plugging 12V@3.5A adapter into Power Jack (J902)

(5) Power on I.MX8MQ board via SW701 Switch

  1. Software Preparations

(1) Related windows drivers for i.MX8MQ MEK

                Windows 7 64bit or windows 10 64bit will find new devices and begin to search and install corresponding drivers, like below:

                Probably windows 10 64bit can’t automatically install CP2105 driver from official website of manufacture:

https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

                Then installed it manually.

(2) Power off i.MX8MQ MEK

(3) Installing winusb driver by zadig

                According to method described in uuu.pdf, download zadig tool from https://zadig.akeo.ie/, and install it to windows 7 64bit .

[Note] windows 10 64bit doesn’t need to install winusb driver.

Press OK.

Then press “Close”

Close SDK Manager Installation Guide .

Find the directory of SDK Manager installation, and enter into “platform-tools”, like below:

D:\i.MX8-Projects\IMX8MQ-MEK-windows-drivers\android-sdk_r24.4.1-windows\android-sdk-windows\platform-tools

  1. Beginning to download android images to I.MX8MQ MEK via UUU Tool

(1) Downloading android DEMO images for i.MX8MQ MEK

https://www.nxp.com/support/developer-resources/software-development-tools/i.mx-developer-resources/...

After downloading it, decompress it to a directory.  Like below:

(2) Downloading UUU Tool

https://github.com/NXPmicro/mfgtools/releases

After downloading uuu.exe,  copy it to the directory of android 9.0 demo image , see above.

(3) Run command “uuu_imx_android_flash.bat -f imx8mq -a -e

----Power on i.MX8MQ MEK.

----open a command line window

---open Hyper terminal ( set it 115200 bps)

pastedImage_15.png

---run “uuu_imx_android_flash.bat -f imx8mq -a -e

          For windows 10 64bit, downloading images will be done without any errors.

   But for windows 7 64bit, downloading images will stop at “ waiting for any devices”.

   It means Android ADB driver will be needed. Follow the steps below to solve the problem.
