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!

    Why do you want bluetty?

    If you want bluetooth support, maybe you should select from top level menuconfig,

    Networking --> [*] Bluetooth subsystem support ---> Bluetooth device drivers ---> [*] HCI USB driver

    The isp116x driver does not use DMA. It looks like the hcd driver crashed after detecting port

    You should enable DEBUG in your driver, or add some printk() to find out.

    You should try out the 2.6.15.6 kernel in the update of the buildroot guide.

    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.

    so in that case should i be updating the 2.6.16 kernel with the more complete code from 2.6.x? some of the code in 2.6.16 have data structures which have some data members stripped out for some reason

    You should update arch/nios2nommu/usb.c data structure for newer kernel.

    Thanks hippo!

    while looking for guides about porting over drivers, i found this for the 2.6.x distribution

    http://blackfin.uclinux.org/plugins/scmcvs...root=uclinux533 (http://blackfin.uclinux.org/plugins/scmcvs/cvsweb.php/uclinux-dist/linux-2.6.x/drivers/usb/host/?cvsroot=uclinux533)

    not sure if any changes need to be made since the hardware is different from blackfin? (in the header files)

    i&#39;ve tried plugging in a usb flash drive but nothing happens after trying:

    1. in root fs, you need some scsi dev nodes, eg sda, sda1... to use mass storage dev

    you need usbfs, too. I have setup them in the post of buildroot guide, so they are ready.

    2. in kernel menuconfig,

    turn on file system support, eg, vfat and native lang codepage 437

    turn on scsi device, scsi disk

    turn on host-side usb, usb dev fs, your hcd, usb device eg mass storage.[/b]

    --- Quote End ---

    for 1. do i need to do anything else for sda and sda1? - usbfs seems to be registered

    for 2. i&#39;ve enabled all of those options.

    sorry about the huge post but thx in advance!
