Hello Neuber Sousa,

The i.MX7D Pico board is manufactured and supported by TechNexion so I would recommend that you contact them especially in case you detect a hardware error.

That being said, I would recommend trying to restore an image by following the document below as it could be that the booting image is not correct, but it’s loaded and it’s not letting the board to enter serial downloader mode.

My apologies for the inconvenience. I hope this helps,

Regards,

Hello Neuber Sousa,

I’m not sure it if may be a driver problem. Have you checked if the Android Things Setup Utility works?

https://developer.android.com/things/hardware/imx7d

If this doesn’t help I would recommend reaching TechNexion as they manufactured the board and may be able to assist you better on how to determine if it’s a hardware problem or not.

Regards,

I put multimeter in 5v and Gnd gpio and I get 5.01 to 5

04. I put multimeter in 3.3v and Gnd gpio and I get 3.37-3.38v.

I find this values too high in compare with Rpi
