isp1362-hcd.c USB driver help

You may check the post from nacide, who backported the isp1362 hcd to 2.6.11,

http://forum.niosforum.com/forum/index.php?showtopic=4069 (http://forum.niosforum.com/forum/index.php?showtopic=4069)

You should check if the platform device table is correct.

You should check if you can access ports on the usb chip, and interrupt is routed correctly.

But, are you working on PPC ?

Thanks Hippo...

yep, I am basically using the same source as nacide had in that message..

(yes, it is a ppc// motorola mpc8247 processor...) I don't there is anything wrong with the driver per say... since others have used it and seems to be working for them... it is probably something I did while getting it to work with my new board we built up.. (may even be a hardware problem.. not sure..)

I am getting the interrupts ok.. (just not the ATL one I think.... which is what seems to unload incoming ptds... at least that is my guess)..

I get the HUB timeouts... errors -110... so it is like nothing is coming back from the flash disk.. but the dmesg output seem s to indicate something did but just didn't get retrieved from the chip.. (via the ATL interrupt)...

at least that is my guess.. not knowing usb that well yet, I am just guessing...

thanks!!

OH, and yes, I am posting questions to the linux-usb-devel list as well.. but I saw activity on here and was hoping by chance, I might get help here as well.

thanks again for any insight/help...

That&#39;s OK.

You should check your hardware first before debug the software driver. You should write a simple program to do some registers access, and check the timing with a scope or LA. Hardware must be tested at much as possible.

Then trace thourgh the isp1362-hcd.c . Watch for the reset and initialization.

After that the usb will detect the root hub. You should read ch13 usb of the book Linux device driver 3rdEd. It will give you more insight.

thanks... yep I get basically the same for the boot log... (except the timeout error occurs) does anyone out there have a dump from the dmesg file with debugging turned on?? so I might be able to compare with mine and see where it is going wrong..

we have checked out the hardware... and I think it is ok... i can write/read the isp1362 chip ok.. and I am seeing activity on the bus...

thanks bob

issue resolved.... in the end it was related to byte swapping things correctly... the ptd header needed the bytes swapped one way and the rest of the data(the urb payload) needed the bytes swapped the other way...

there is only one function is there to write/read both (ptd header and payload) to the fifo&#39;s... so I had to make two functions and whola, it started works...

Hi bobw0299

I found your query on Altera forum, I am doing a project on DE2 board which requires USB communication of board with PC.

I want to transfer data from pc to board and send some command to board so that my VHDL design will perform some task.

I wonder if you can help me regarding USB communication stuff, could you please guide me how to approach for the same using VHDL and/or C or any other method. how can I start and what issues are to b considered? how can I start writing hardware on board and driver on pc?

your assistance will help me a lot, waiting for your reply.

Thanks and Regards
