5600 As A Usb Drive

[ebank]

I am trying to set up my 5600 with the Watapon (sharp based) rom to act as a usb drive as described here:
http://people.bath.ac.uk/enpsgp/Zaurus/binaries/ (bottom of the page).

I do have a CF memory card plugged in.
Output from lsmod Before running the script.
bash-2.05# /sbin/lsmod
Module                  Size  Used by
pxa_bi                 21328   0  (unused)
net_fd                 25024   1
usbdcore               34544   0  [pxa_bi net_fd]
registers              26416   0  (unused)
usbdmonitor             5248   0
sharp_mmcsd_m          26256   2

When I run the script start_storage.sh, it looks like it runs fine until the last line:
/sbin/insmod /lib/modules/2.4.18-rmk7-pxa3-embedix/kernel/drivers/usb/device/bi/pxa_bi.o shortpacket=1 recvpacket=256

Which throws this error:
Invalid parameter parm_shortpacket

If I remove the parameter shortpacket, I get:
Invalid parameter parm_recvpacket

If I also remove the recvpacket parameter, I don’t get any errors, but then when I try to connect it to my PC, It sees the usb device, but it doesn’t know what it is.

Do I need a different pxa_bi.o?
Can someone tell me how to get the correct one?

Is there something I am overlooking?  I would really like to get this to work.

Thanks
Ed

The pxa_bi.o file is from your Zaurus anyway so it should be the right one.

Perhaps the 5600's version of pxa_bi.o doesn't accept arguments - this seems to be the case. What info does the PC return about the usb device when you remove the two parameters?

See attached JPG for the windows XP error.  Basically it says that it is a Unknown USB storage device.

Maybe the parameters are named slightly different?

[lardman]

modinfo will tell you any parameter names.

Have a read of these and see if anything rings a bell:

Here is the results from modinfo:

I think your using the wrong storage module?

This is the one I have had 'some' luck with on a 5600:

It 'was' in one of the old threads that lardman posted links to. I believe that the other one was for the sa1100?

[lardman]

I'll take a look at the modules I have kicking around and let you know.

Greg, Could you post the output of modparm for your pxa_bi.o?

[Greg2]

Greg, Could you post the output of modparm for your pxa_bi.o?

It's the same pxa_bi.o that you have... it's from the sharp rom.

Would you like me to attach the storage module here?

Greg

[ebank]

Greg,
Please attach it.  Can you also post the scripts you use?
Or if you don’t use scripts, what parameters you use?
Can you also describe what you mean by ‘some luck’?

Thanks
Ed

An aside:

You're using watapon aren't you - does this have any kernel differences to the standard Sharp kernel?

Si

[ebank]

From the Watapon Web Site:
http://www.duelmonsters.ca/zaurus/

Kernel
2.4.18-rmk7-pxa3-embedix
Standard 5600 Config
XScale Cache Workaround DISABLED (effectively doubles processor speed compared to default kernel -- may cause minor instability, although I haven't noticed much -- only with some movies and some games)

I am trying to set up my 5600 with the Watapon (sharp based) rom to act as a usb drive

This could be part of the problem. I was not able to make this work at all on the Watapon Rom.

Over a year ago when Chaos had more time and was working on his Watapon Rom I suggested to him to include this feature. He requested the info and I gave it to him, but it never became a feature of his rom.

All the info is in the threads lardman has linked in his post. As is noted in the thread... I have only made this work on the original sharp rom v1.32 with the special kernel v1.3. I should also add that I have never tried to use it with windows, but I have mounted it with the terminal on a linux box as:

mount /dev/sda

As for the 'some luck' part... it doesn't 'always' mount on the first try.

Greg

Here are lardman's original scripts (with an error corrected as per the thread it was in) and module from that thread:

Thanks Greg,

Ed, I should have some more time after Xmas to look into this if you still need help then.
