Hi,everyone

 

I have got a reboot problem with IMX6Q sabresd on my custmer board and described as following:

 

1.Linux BSP 4.1.0,when I enter reboot command,system will reboot fail in most cases,only about 10 percentage system reboot success.I have refer the following site:

        https://community.freescale.com/message/408776#408776

   And comment out "bic r0, r0, #0x0006",but it is not useful.

 

2.Accidental,I tried BSP rel_imx_3.0.35_12.09.01,and find that reboot command always runs successfully.I have compared the following function with the two BSP:

arm_machine_restart    cpu_proc_fin    arch_reset

There are some differences in arch_reset.Then I modify BSP 4.1.0 code arch_reset function same as rel_imx_3.0.35_12.09.01's,but reboot command also fails in most cases

 

Anyone can help me?
