Honored ContributorIRQ 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! io scheduler deadline registered 116x: driver isp116x-hcd, 08 Apr 2005 116x: ISP116x Host Controller, irq 4 isp116x-hcd isp116x-hcd: new USB bus registered, assigned bus number 1 hub 1-0:1.0: USB hub found hub 1-0:1.0: 2 ports detected scheduling while atomic: swapper/0x00000002/1 Stack from 00187d40:<0> <0> 00000002<0> 000d53cc<0> 00000001<0> ffffe000<0> 00002900<0> 001922ec< 0> 00189b20<0> 00356c00<0> <0> 40408180<0> 00000002<0> 000e5504<0> ffff8c59<0> 00000006<0> 000d696c< 0> 00150020<0> 00150020<0> <0> ffff8c59<0> 4b87ad6e<0> 000170f0<0> 00182d60<0> 0014fd50<0> 00000002< 0> ffffe000<0> 80000080<0> <0> 000175bc<0> 001921c0<0> 00192280<0> 000be790<0> 001921c0<0> 00192280< 0> 000bf130<0> 000df488<0> <0> 00000000<0> 00189a20<0> 0000000d<0> 000001f4<0> 00356c04<0> 00357d9c< 0> 000600fc<0> 00179200<0> <0> 0035ada4<0> 00000000<0> 00192294<0> 00356a00<0> 00000001<0> fffffffa< 0> ffffffed<0> 000ecc94<0> Call Trace:<0> <0> [<000bcf18>]<0> [<000a1e04>]<0> [<000a1eb8>]<0> [<00000001>]<0> <0> [<00000000>]<0> [<00000000>]<0> [<000a20a8>]<0> [<00000000>]<0> <0> [<000a0e68>]<0> [<00000000>]<0> [<00000000>]<0> [<000c5c68>]<0> <0> [<00000001>]<0> [<00000000>]<0> [<00000000>]<0> [<00000000>]<0> <0> [<000001f4>]<0> [<00000001>]<0> [<00000000>]<0> [<000bf95c>]<0> <0> [<00000012>]<0> [<00000012>]<0> [<00000012>]<0> [<000c2034>]<0> <0> [<00000001>]<0> [<000a1e04>]<0> [<000a1f74>]<0> [<00000000>]<0> <0> [<000a22c8>]<0> [<00000001>]<0> [<000a2830>]<0> [<00000000>]<0> <0> [<00000000>]<0> [<00000264>]<0> [<00001d64>]<0> [<00006910>]<0> <0> [<00006968>]<0> [<0000088c>]<0> [<00000000>]<0> [<00000000>]<0> <0> [<00000000>]<0> [<000052a8>]<0> [<00000000>]<0> [<00000001>]<0> <0> [<00000b00>]<0> [<00000b00>]<0> [<0000019c>]<0> [<00000000>]<0> <0> [<00000120>]<0> [<00000001>]<0> [<00000001>]<0> [<00001d54>]<0> drivers/usb/class/bluetty.c: USB Bluetooth support registered usbcore: registered new driver bluetty drivers/usb/class/bluetty.c: USB Bluetooth tty driver v0.13 Initializing USB Mass Storage driver... usbcore: registered new driver usb-storage USB Mass Storage support registered.

Altera_ForumWhy 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 <div class='quotetop'>QUOTE </div> --- Quote Start --- hub 1-0:1.0: 2 ports detected scheduling while atomic: swapper/0x00000002/1[/b] --- Quote End --- 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.- Altera_Forum
hmm, I don't see any DEBUG option in the makefile, how do i enable the debug option?
thanks! - Altera_Forum
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 . - Altera_Forum
thanks, i'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't complete or don'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. - Altera_Forum
Yes, there may be new data structures and api in new kernel, which makes old driver failed.
- Altera_Forum
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

I will try to borrow a DEII board, and I will check it then.
