SAM-BA CDC 2.9 rc6 driver fix for Ubuntu 10.04

Hi Ubuntu users,

In case you use Ubuntu and have upgraded to 10.04 you might have noticed
- as I have - that "connect" freezes when launching (in my case
SAM9260).

I posted a fix on www.at91.com

The fix works fine for me, proviso you're using a clean 10.04 install.
I just used the 2.6.31.6 kernel driver usb-serial.c and
usb_serial_generic_open and ignored the filp args in the open calls,
recompiled and replaced the lib usbserial.ko module.

A bit of a relief, instead of fiddling with new kernels et al... :-)

If anyone needs the mod'd driver and can't access at91.com, I can post
it here.

Hope this helps others not being put off by Lucid Lynx :-)

Best regards,
Kris

Hi Kris

I'm not able to find this fix (I don't understand why but www.at91.com forums doesn't show any topics :-() could you email it to me ?

Thanks

Hi kris,
I am using an Olimex sam7s256 board. I tried to get it up and running in linux (Ubuntu). I was able to successfully install GCC and binutils. I installed SAM-BA for linux from the atmel site. I was able to get the USB port for connection as specified in the SAM-BA manual (.dev/ttyUSB0). But when I try to use the GUI and 'connect' there is no response. I though that there is a connection failure, so when I presses the reset button in the board, I get a message "Failed to initialize FLASH accesses". No matter how long I wait before pressing the reset button, I am not getting any SAM-BA window as given in SAM-BA manuals.
an any one one help me out in this? I did the 'tst' jumper set, reconnect the board for 10 s, disconnect and 'tst' jumper reset, reconnect before opening SAM-BA. Any help will be greatly appreciated. I am stuck. It is the same for both SAM-BA 2.9 and 2.8.
Can this be rectified by changing any parameters in the accompanying TCL files...
Thanks.
You were talking about some 'fix' for your problem. I am interested in knowing that b'cos I just did a fresh install of 10.04 Ubuntu and used SAM-BA 2.9 (i did try 2.8 and 2.9 too.)
If it is not possible can you suggest any other tool to flash the board other than SAMBA or should I buy the JTAG and do it with openOCD?
Thanks in advance.

Krish.
