Hello,

SOM:Apalis IMX8QM 4GB
Board:Ixora
OS:Android 11 from Kynetics

When trying to get the device to fastboot mode by “adb reboot bootloader” it seems like the device goes into fastboot mode and in Device manager I could see “USB Download Gadget” however fastboot devices cannot detect any devices.
Am I missing something here?
Thanks in advance!

Hi @vsr138

which OS are you using on your computer? Which version?

Can you also post the output of:

fastboot --version

Thanks

Hi @diegor
I tried with 2 computers
1.Laptop with Windows 10
2.PC running Windows 11

the results were same on both
fastboot --version gave fastboot version 34.0.3-10161052 on the laptop
and
34.0.4-10411341 on the PC
thanks

Hi,

the device should not appear as “USB Download Gadget”.

Please follow these instructions to select the correct Windows driver for fastboot use:

Hi @diegor
Thanks for your response, but we had already tried this fix. Even though after selecting ADB device and selecting yes in the popup, it doesn’t seem to change.
Do you suspect it is because of the Driver Signature Enforcement?

thanks

Hi,

Even though after selecting ADB device and selecting yes in the popup, it doesn’t seem to change.

What do you mean with “it doesn’t seem to change”? Do you still see it as a “USB Download Gadget” despite selecting ADB device? Can you post a screenshot of how the device appears in your “Device Manager”?

Thank you

Hi Diegor,

Yes, exactly. I still see it as “USB Download Gadget” despite selecting ADB device.

Hi,

in that case, the issue is for sure that the driver change didn’t occur.
The “Adb device” is not signed, so you need to make sure driver verification is not enforced:

Hi Diegor,

We had been suspecting the same.
However we now tried with Driver Signature enforcement disabled( bcdedit command returns nointegritychecks as Yes), but the device still shows as a USB Download gadget(This is in a Windows 11 PC).

Hi Diegor,

Adding to my previous response,

We tried the same with a Windows 10PC(nointegrity checks YES while running bcdedit) but still the driver change doesn’t seem to happen.

Hello vsr138

U-boot needs a patch to enable fastboot and ADB correctly (TDX_CFG_BLOCK disabled) for windows. We will release a new image with th fix in 3/4 weeks.
In the mean time you can use a Linux host and you won’t have any issue.

Thank you,

Hi @nicola_lg
Thanks for sharing this information.
We tried with a Linux host VM and fastboot device could be detected. However,
“fastboot flashing unlock” won’t get completed, waited an hour and still nothing happens.
So, flashing also does not go as expected.
Running the fastboot_imx_flashall script is stuck at 1st stage (flashing partition_table.img)

We are not sure which process you are using for flashing the image. We support Toradex easy installer for image programming.

Thank you,
