Hi anandraj

these messages are not errors, hanging may be caused by wrong

image (for example not for this board), one can try official demos below

and boot from SD card

L3.10.17_1.0.0_IMX6QDLS_BUNDLE : Source Code Download Steps Documentation and Demo Images.

L3.0.35_4.1.0_DEMO_IMAGE_BSP

Hi anandraj

seems this is due to errors, please refer to attached file with porting hints.

One can add printfs in code to find out where problem occurs.
