Hi @neuberfran. Welcome to Mender Hub. Hopefully we can help you with this. From the “new issue 3.png” file it appears you have an Imx6 based system, not imx7. The USB Vendor/Device is 0525/b4a4 which according to the output from the imx\_usb run is mx6. Also, when you post, please copy/paste the actual text rather than a screenshot; it makes it easier to search on. Thanks, ---

No. I have imx7 pico kit. I had, I have android things installed on it until yesterday. ---

Hello friend, help me please. I need to show you at least two more images that show when I first gave the sudo ./imx\_usb SPL and sudo ./imx\_usb u-boot.img commands. ---

I can’t explain it then. It’s registering to your usb system as the imx6. Perhaps @jorisoffouga can help since he did the initial implementation of the Pico-Pi platform and likely has the hardware. ---

Hi @neuberfran where is your serial output? Connect the serial debug. You can see ttyUSB0 in /dev entry ---

Try “reset” and that should reboot the board. You will get a U-Boot header and other info printed. All of that will be useful in troubleshooting. Specifically for the ums command, try the following: =\> usb start =\> mmc rescan =\> mmc list =\> mmc info ---
