Boot for Linux Image on iMX8M Quad Evaluation Kit

[hariasti_srimal]

Hello,

I flashed linux image into eMMC and boot it on iMX8M Quad Evaluation Kit. But seems Android system is booted (Android logo is appeared on HDMI display) as Android image is programmed in the eMMC by default. Could you please help how to boot Linux Image instead of Android?  Here is the console message. Any comment is very helpful. Thanks so much in advance.

Hi @hariasti.srimaldia-1@alpsalpine.com ,

From logs it seems like you are using L4.14.98, You can follow the steps from section 4.2.2 Using UUU (from attached yocto project's User's Guide )to flash emmc using UUU. 

Please make sure that image is flashed properly on emmc and your board is in serial download mode when you  are flashing the image using UUU. Also verify that Boot mode switches are proper for serial download  mode and to boot from emmc.

Regards,

Radhika Somaiya.
