Linux 3.10.17 i.MX6S SOLO boot problem

[marcocavallini]

Hello,

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

hi ,

Am trying uboot and kernel flashing on eim-nor ( parallel-nor ) from imx-3.10.17-1.0.0-ga-mfg-tools archive on my imx6solo (imx6dl) board , flashing is success but after flashing uboot doesn't come up.

Any help in troubleshooting this problem ?

Thanks.

Hi Marco,

You should try to use imx6sl-sabresd-ldo.dtb as a reference for your dtb.

U-boot mainline does not support LDO-bypass.

Also, can you run memtester in Linux?

Hi Fabio,

FYI my CPU is SOLO (not SoloLite), is imx6sl-sabresd-ldo.dtb suitable for it?

What do you mean with memtester? The target doesn't boot.

Regards,

are those from Linux 3.10.17 demo image ?

[marcocavallini]

no are from my build 3.10.17 image

[igorpadykov]

suggest to check with L3.0.35_4.1.0_ER_SOURCE_BSP

this ltib distro does not use device tree, so you can check

if issue is caused by DDR errors or device tree configs.
