MXC_Restart fails (Linux kernel bug?!)

Hi experts,

 

I'm trying to reset my custom iMX6DL board running Linux 3.10.53.

Performing a 'reboot -f' fails.

 

Looking at the code, I think the value written to WDOG Control Register is incorrect.

The value written is 0x14, but it should be 0x04 --- shouldn't it?

(arch/arm/mach-imx/system.c   function mxc_restart)

 

In any case-- performing a simple "devmem2 0x20bc000 h 0x0004"  resets the device successfully.

 

 

Sincerely,

Erez
