i.MX6 Solo kernel unable to boot "undefined instruction"

[DipenPatel1z]

Dear All,

We have designed i.MX6 system on module based on SabreSD board. I am able to boot and program Quad/Dual version. But I have issue booting with Solo version. I am using Freescale Yocto BSP 3.10.17.

While booting via serial down loader mode using Mfgtool kernel stops saying "undefined instruction".

Using Device Tree in place at 18000000, end 1800d40e

Starting kernel ...

Hi Dipen

issue may be caused by DDR errors, you may wish

to check it with tools below

https://community.freescale.com/message/331721#331721

https://community.freescale.com/docs/DOC-96412

Also I would suggest to check MFG Tool functionality with old ltib version,

with it additionally MFG Tool (its firmware) should be rebuild for

custom board configuration:
