iMX6 SabreBoard won't boot

[Alex_Smart]

I recently purchased sabre board MCIMX6Q-SDB, followed instructions
https://www.nxp.com/document/guide/getting-started-with-i-mx-6quadplus:GS-RD-IMX6QP-SABRE

and there is nothing - no signal on HDMI monitor, nothing on USB serial terminal. Where is  the catch?

Ok Im getting log output (changed USB port), monitor still black. What stikes me is that documentation is messed up. A lot. Links leading to nowhere, mention of files that can not be found. Im trying to upload a Linux image but "Wait for Known USB Device Appear..." is all I got.

Hi @Alex_Smart!

Thank you for contacting NXP Support!

Do you set the SW6 correctly?

Do you flash the sd card?

You can try flashing the board using the uuu tool.

The prebuilt images are available in the link below:

Hi @Alex_Smart!

In your board you have two usb ports.

1) Is for terminal debug only

2) USB OTG

the second is used to flash the board

If you can see the debug console you have to stop the terminal in U-boot and use the comands below to see the image under HDMI.

U-Boot > setenv mmcargs 'setenv bootargs ${bootargs} root=/dev/mmcblk3p2
rootwait rw video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24'

U-Boot > boot

Best regards!
