How to get into the Android recovery mode for imx7 development board MCIMX7ULP?

[zoy74758]

I use Android bsp on MCIMX7ULP-EVK REV B1 development board.
I am trying to get into the recovery mode of imx7.

Using adb, I run
> ./adb reboot recovery‍
It takes the device to boot splash screen and stuck there.

Another try: I turn on the device while pressing on button and volume down.

The device goes to black screen and stuck there.

Does recovery mode even exist?

Hi,

So sorry the i.MX 7ULP Family are on PREPRODUCTION, and we TIC team do not get all the files on the i.MX7ULP. In our past design, there is recovery mode support.

About recovery mode you can refer to the steps in the document Android_Frequently_Asked_Questions:

Press "VOLUME DOWN" and "POWER" to enter Recovery mode. This check is in u-boot.git board support file, where
you can change your preferred combo keys.
Also, you can input this command in the console:
# reboot recovery # the board reset to recovery mode.
to enter recovery mode.

About the i.MX 7ULP we still do not know. Hope this can do help for you.
Have a great day,
TIC Rita

VolDown+On/Off buttons do not work for me.
But
reboot recovery
inside adb shell works.

Thanks
