Hi Leo

USB work on mpc8347 now.
Thank you for your help.
The cause was Clock signal was not connected to USB.

And I have the other problem.
I need to java run time environment on mpc8347.
I do not know where i can get it.
Could you tell me if you know.

I have no particular knowledge about installing JRE on Linux.  Google
leads me to this link which might be helpful: http://openjdk.java.net/

 Subject: USB does not work on mpc8347
 
 Hi all,
 
 I am running the Linux kernel 2.6.28.7 on my PPC8347 BRD.
 I have some problem.
 
 One is USB does not work on mpc8347.
 platform_driver_probe(udc_driver, fsl_udc_probe) is failed.
 struct is
 static struct platform_driver udc_driver = {
   .probe = fsl_udc_probe,
   .remove  = __exit_p(fsl_udc_remove),
   /* these suspend and resume are not usb suspend and resume */
   .suspend = fsl_udc_suspend,
   .resume  = fsl_udc_resume,
   .driver  = {
 //.name = (char *)driver_name,
   .name   = fsl-usb2-mph,

Why are you changing this?  Mph module can only be host, not the device mode 
supported by this driver.

   .owner = THIS_MODULE,
   },
 };
 I do not know why it fails.
 Do i have to do something ?

So what function did you try to test?  Host or device?  For host mode, you 
should look into the drivers/usb/host/ehci-fsl.c file.
