IMX6DL is blocked when staring up

[songyonglai]

Hi All:

  My own board ,similar to FSL demo board, when staring up , can not go to the console, it seams blocked.

When I press ctrl+c, it can not be stopped, I think something is in definitly while loop.  The starting log as follows,

Thanks very much.(I use the yocto linux 4.1.15)

Hi yonglai

may be recommended first to run ddr test

i.MX6/7 DDR Stress Test Tool V3.00 

and try official nxp kernel from source.codeaurora.org/external/imx/linux-imx repository

linux-imx - i.MX Linux kernel 

Linux 4.1.15_2.1.0 BSP & Multimedia Codecs Documentation

Hi igorpadykov:

    Thanks for your reply. I use the NXP kernel http://git.freecale.com/git/cgit.cgi/imx/linux-imx.git/snapshot/rel_imx_4.1.15_2.0.0.0_ga.tar.gz ,  mfgtool is

L4.1.15_2.0.0-ga_mfg-tools。It seems not the DDR's problem, When I replace the rootfs.tar.bz2 file from old mfgtool version Mfgtools-Rel-4.1.0, it can start up successfully and can go to console.  It seems the rootfs.tar.bz2 is not OK in the new mfg tool L4.1.15_2.0.0-ga_mfg-tools? 

      I need your suggestion and help, Thanks very much.
