Hi,

 

I am working with the uClinux trunk distribution, BF527 ezkit board and Renesas host controller.

 

I made the h/w interface of renesas HC with BF527 ezkit as follows.

 

CS - > AMS#2 , Interrupt, DMACK and DMA Request signals are connected through PF Pins.

 

I have enabled the make menuoptions as follows.

When i boot the kernel. I saw the init function "static int __init r8a66597_init(void)" is called, but the probe function is not called?

 

What changes I should make in the kernel driver to make it up and running? are there any test procedure available please send your comments and suggestions.

 

Thanks and Regards, Sreedhar

Sreedhar:

 

We have no plans to support any other USB chip that ones that we have already validated.

 

  docs.blackfin.uclinux.org/doku.php?id=hw:cards#usb

 

If you want help - use one of the existing ones we have allready validated. If you don't want to use one of those - figure it out yourself - sorry.

Message: 72984    I guess you also need to add some platform memory and irq resources.

And by the way - only you know how you connected the USB HC.
