Linux 3.10.17 i.MX6S SOLO boot problem

Question asked by Marco Cavallini on Mar 1, 2015
Latest reply on Mar 9, 2015 by sunc xun


I am trying to port Linux version 3.10.17 to an i.MX6 SOLO (Not Solo Lite)

I started from the imx6q-sabresd configuration as foudation for the first test

  make imx_v7_defconfig

  make -j4 uImage LOADADDR=0x10008000

  make imx6q-sabresd.dtb



Is this the correct way to proceed for MX6 SOLO ?



The problem is that kernel hangs at the line below just after trying to mount the mmcblk0

Sometimes some messages appear but they don't give much information.

I need a help to understand where to dig in order to continue the boot process.


Thank you
