Hi Team,

 

I am using the IMX8MQ EVK and want to flash images using the uuu utility.

 

I am able to load the images over mfgtool to board but I am using the linux system so want to flash the images using the "uuu".

 

Version of the uuu is "1.2.39-2-g9587056"

Here I am using the command as follows.

  1. Place the EVK in flash mode by changing the SW802 to "01"
  2. Connected the USB typeC cable between PC and EVK.
  3. Connected Micto USB cable on USB debug port.
  4. Power on the EVK

 

After this command I am applying the command as follow

  1. ./uuu -b emmc imx-boot-imx8mqevk-sd.bin-flash_evk

Which internally apply the command

./uuu SDP: boot -f imx-boot-imx8mqevk-sd.bin-flash_evk

Output on EVK side on Console

U-Boot SPL 2017.03-imx_v2017.03_4.9.88_2.0.0_ga+gb76bb1b (Dec 19 2018 - 19:55:41)

Back to ROM, SDP

2. After this command we apply the command on PC side

./uuu FB: ucmd setenv fastboot_buffer <address>

Wait for Known USB Device Appear...

Here, it stuck and don't find the USB device.

 

Same issue is coming with the FBK command also .

 

Can you please help us to find the reason behind the not getting the usb device when use the FB command but when use the SDP then it is getting the USB device.

 

Please let me know if you need any more information from my side.

 

Thanks & Regards,

Dhaval
