i.MX6Q Android can't boot up

YanjunLuo — Tue, 12 Aug 2014 07:08:01 GMT

Hi,

My custom i.MX6Q board can't boot Android, I can enter to Android console, and after several seconds, it just go to suspend. I built my own kernel, and the Android is probuild image of android-imx6-r13.3, I boot from NFS. I did see the similar questions here, but no answer for it.

BTW, my board works fine with Linux already.

Uncompressing Linux... done, booting the kernel.

Thanks for your information, can you tell me more details? I check the serial console, the whole system go to suspend, not display only.

Re: i.MX6Q Android can't boot up

YanjunLuo — Tue, 12 Aug 2014 08:30:48 GMT

If I connect the USB OTG to my PC, my PC shows the right SABRESD-MXDQ device, and my board will not suspend any more. Although I can't see anything on the LVDS LCD, I think that should be another problem, I'll check it later.

I can see there are many process running already, the Android should works, but why it suspend without connect the USB cable? Since I don't have any wake up button. I don't know how to wake up it.

Hi,

Can you send the logcat detail?

Thanks, I found the problem, because there are no input devices now, then Android suspend, I just fixed the LCD and connect a USB mouse, I can wake up it and works well now.

Regards,

Yanjun Luo.

correct, most probably it didnt suspend because it was receiving interrupts from the USB.

Actually suspend is nature feature of Android, we can just creat a suspend lock then it'll not suspend anymore. This is my first project with Android, there are long way to go.
