hmm, I don&#39;t see any DEBUG option in the makefile, how do i enable the debug option? thanks!

The problem should be in arch/nios2nommu/kernel/usb.c . But you have to enable the DEBUG in drivers/usb/host/isp116x-hcd.c to find out. you should use kernel 2.6.16 .

thanks, i&#39;ve traced down the problem using the trace and printks to an msleep call in drivers/usb/core/hub.c in the 2.6.x kernel Just tried compiling 2.6.16 kernel but it seems some of the data structures aren&#39;t complete or don&#39;t match up. the isp116x_platform_data data structure seems to be missing some things that usb.c assumes are there and is trying to initialize.

Yes, there may be new data structures and api in new kernel, which makes old driver failed.

IRQ mapping in SOPC builder

I fixed up the device address (na_usb - to the address assigned to ISP1362 in SOPC builder) and irq (na_usb_irq - IRQ 4 when viewed in SOPC builder) and corrected the chip id so linux recognizes the usb port, but i get the following error about the IRQ after i plug in a USB flash drive. I checked the DE2_NET design I'm using for this experiment in SOPC builder and the IRQ for ISP1362 is 4, or should i instead be using the IRQ for the DMA?

thanks in advance!

Shindou,
Good found, It looks like the piece of driver you need. you have to update your arch/nios2nommu/kerbel/usb.c to prepare for the probing of the 1362 hcd. You should enable the debug message, too. You have to "port" the driver to your nios2 board. (it is not plug-and-play...).

The 1362 hcd should detected first, then the root hub.
Then when a usb disk inserted it will detect the new usb mas storage device, and display the usb disk info.

This is what I found from the net, about the boot log of isp1362 on arm.
I am trying to add isp1362-hcd to nios2 kernel, and will let you know when I compile through.
I can not borrow a DEII board, so it is up to you to test them.

it didn't initialize the isp1362-hcd,
Did you select isp1362 hcd in kernel menuconfig?

Try add some printk and debug to the code, arch/nios2nommu/kernel/usb.c and drivers/usb/host/isp1362-hcd.c .

It seems like it's getting to the usb_hcd_init() call in arch/nios2nommu/kernel/usb.c where platform_device_register(&isp1362_hcd) is called but it seems the init code in drivers/usb/host/isp1362-hcd.c (ie. isp1362_init() is never called)

last edit:

Yep, ISP1362 HCD is selected in the menuconfig - hmm, interesting point tho, there's no object file after the make (ISP1362-hcd.o) in the drivers/usb/host directory. It's strange tho, the code in an adjacent directory drivers/usb/core had object files. Probably explains the problem above why that code never got called. Gonna see if i can figure out why this makefile isn't compiling isp1362-hcd.c.

try make clean, and rebuild kernel from hwselect again.
