mxc_iomux_v3_setup_multiple_pads causes instant kernel reboot

Question asked by patrickgreß on May 27, 2013

Dear community,


I recently tried to create an image for a SABRE Platform board based on an existing working image. But when I tried to compile an new kernel for the image, the kernel instantly reboots when calling mxc_iomux_v3_setup_multiple_pads(mx6q_sabresd_pads,ARRAY_SIZE(mx6q_sabresd_pads)) in  mx6_sabresd_board_init of file board_mx6q_sabresd.c.


Removal of the call to mxc_iomux... makes the kernel boot without further problems, but the touchpad is not working, of course.


For kernel compilation I used the package provided by freescale (L3.0.35_4.0.0_ER_SOURCE)  with all the patches applied. The configuration of my kernel is based on the configuration of the working kernel, nothing was added or removed yet, so I expect it to work, which is not the case.

The working kernel is of version 3.0.35, which is the kernel I want to use.


Any help or insight is highly appreciated.


Kind regards,




GCC Version: 4.7.3
