Re: Linux kernel 4.1.15 hangs

Hi Erik

reason may be wrong image : for example used files for i.MX6Q, not QP or for another board

for example SabreSD while these log shows configuration for Sabre AI board.

In general recommended to flash media using mfg tools with appropriate *.vbs file, for i.MX6QP

mfgtool2-yocto-mx-sabreauto-spi-nor-cpu3.vbs. Another reason may be ddr errors

if custom board was used: then it is necessary to perform ddr test

https://community.freescale.com/docs/DOC-105652

and rebuild image with changed uboot *.cfg file with new ddr calibration coefficients.

Best regards
igor

Do you have HDMI splashscreen enabled in U-Boot? If so, can you try to disable it or try booting without a HDMI cable connected.

Hello Fabio,

I have the same issue. As you mentioned, i tried to remove the HDMI cable and boot. It actually boots flawlessly.

I need your help.

Regards,

Manju
