Re: [ts-7000] libusb

[Dino Sbrocca <>]

Anand,
 
 I downloaded the libusb source and tried to cross compile it from scratch on my SUSE linux host.  It failed. 
 
 The .so binary that I have installed in my cross compile environment and on my TS7260 is libusb-0.1.4.4.0.  This is an older version of libusb than the one I downloaded.  I do not have the original source that I used.  I will never make that mistake again.
 
 I'll start over from scratch now and contact the libusb mailing list for help.  I'll keep detailed notes and send them to you when it works.

Hi Dino,

I tried out the things you had mentioned in your previoue email. They worked until I typed in the make command.
At the make command it gave me an error saying it could not read the
.so file.

"libusb.so: could not read symbols: File in wrong format"

The exact mesage is pasted above.

Is there is a problem with the version of software that I am using? I had downloaded the Linux Crosstool gcc-3.3.4-glibc-2.3.2 -- 0.28rc39 (11-3-2004) from the website.

I look forward to your comments.

I use libusb to communicate with a USB interface chip to a 1-Wire network.  I'm certainly not a linux expert but, the following may help.

To install libusb on the TS7260 I downloaded the source to libusb to a host linux machine and cross compiled it using the following commands:

CC=arm-linux-gcc ./configure --prefix=/usr/local/opt/crosstool/arm-linux/gcc-3.3.4-glibc-2.3.2/arm-linux --program-prefix=arm-linux- --host=arm-pc-linux-gnu
make
make install

I then ftp'ed the .so file to the TS7260 and set the proper authorities.

To run a test program, I first load the USB modules on the TS7260 with TS's /usr/bin/loadUSBModules.sh script and then mount the USB file system with the following command:

mount -t usbdevfs none /proc/bus/usb

The test program was cross compiled on the host and then ftp'ed to the TS7260.  The test program just reads through the buses and devices recognized by the kernal and dumps them to the console.  It's a reasonably good test that you've loaded all the software properly.  Send me an e-mail if you want the source.

Hi,

Has anyone used libusb on the TS7260? Any comments on how to go about using that package on the board would be greatly appreciated.
