Sorry about the spam but have found this really interesting doc:

http://community.slitaz.org/fr/node/14

I'll give a try. ;)
Thanks

Ok I installed the required packages but I am stucked on point 2) (prepare to build). :(

root@slitaz:/usr# cd /usr/src/linux
root@slitaz:/usr/src/linux-2.6.30.6-slitaz# make oldconfig && make prepare
make: *** No rule to make target `oldconfig'.  Stop.
root@slitaz:/usr/src/linux-2.6.30.6-slitaz#       

Moreover, it seems to me that not all the source are in /usr/src. Actually I am looking for a file which should be located at drivers/usb/serial/ . But this folder does not exist...
Here is the command used to dowload the kernel source:

root@slitaz:~# tazpkg get-install linux-source

What am I missing?
Stephane

Yes, the link above is very useful. I think there may be some problem in your installation of linux-source.

But typically, I find the following the easiest:

 tazwok cook linux 

I would also add "make menuconfig" to the linux receipt before cooking. This gives a graphical menu. Then, you can select the module you want and compile the kernel.

EDIT: from kernel configs:

# CONFIG_USB_SERIAL_TI is not set 

Yes, you have to compile your kernel

@jozee,
I am not sure if this is right, but I thought that cloning the wok is required before doing a tazwok cook. Correct???

And as stated here, I can not clone the wok...

Please help.
Thx

Hi,
Here are the required steps in order to add module ti_usb_3410_5052 to linux kernel:

1) Go to source directory (as root):

root@slitaz:/home/sbigler# cd /usr/src/linux-2.6.33.2-slitaz/
root@slitaz:/usr/src/linux-2.6.33.2-slitaz#

2) Enable the required module by editing configuration file (.config) with any text editor.
Look for line # CONFIG_USB_SERIAL_TI is not set and replace it with CONFIG_USB_SERIAL_TI=m:

root@slitaz:/usr/src/linux-2.6.33.2-slitaz# vi .config
# CONFIG_USB_SERIAL_TI is not set   <== remplace this line<br />CONFIG_USB_SERIAL_TI=m                 <== with this one<br />

3) Build needed files and link final module images: [thanks Ernia ;-) ]

root@slitaz:/usr/src/linux-2.6.33.2-slitaz# make CONFIG_USB_SERIAL_TI=m M=drivers/usb/serial
  LD      drivers/usb/serial/built-in.o
  CC [M]  drivers/usb/serial/usb-serial.o
  CC [M]  drivers/usb/serial/generic.o
  CC [M]  drivers/usb/serial/bus.o
  LD [M]  drivers/usb/serial/usbserial.o
  CC [M]  drivers/usb/serial/ch341.o
  CC [M]  drivers/usb/serial/option.o
  CC [M]  drivers/usb/serial/pl2303.o
  CC [M]  drivers/usb/serial/ti_usb_3410_5052.o
  Building modules, stage 2.
  MODPOST 5 modules
  CC      drivers/usb/serial/ch341.mod.o
  LD [M]  drivers/usb/serial/ch341.ko
  CC      drivers/usb/serial/option.mod.o
  LD [M]  drivers/usb/serial/option.ko
  CC      drivers/usb/serial/pl2303.mod.o
  LD [M]  drivers/usb/serial/pl2303.ko
  CC      drivers/usb/serial/ti_usb_3410_5052.mod.o
  LD [M]  drivers/usb/serial/ti_usb_3410_5052.ko
  CC      drivers/usb/serial/usbserial.mod.o
  LD [M]  drivers/usb/serial/usbserial.ko
root@slitaz:/usr/src/linux-2.6.33.2-slitaz# 

4) Copy the module:

root@slitaz:/usr/src/linux-2.6.33.2-slitaz# mkdir -p /lib/modules/2.6.33.2-slitaz/kernel/drivers/usb/serial
root@slitaz:/usr/src/linux-2.6.33.2-slitaz# cp drivers/usb/serial/*.ko /lib/modules/2.6.33.2-slitaz/kerne
l/drivers/usb/serial/
root@slitaz:/usr/src/linux-2.6.33.2-slitaz# ls /lib/modules/2.6.33.2-slitaz/kernel/drivers/usb/serial/
ch341.ko             option.ko            pl2303.ko            ti_usb_3410_5052.ko  usbserial.ko
root@slitaz:/usr/src/linux-2.6.33.2-slitaz# 

5) Install the firmware:

root@slitaz:~# cd /usr/src/linux-2.6.30.6-slitaz/  
root@slitaz:/usr/src/linux-2.6.30.6-slitaz# make firmware_install
root@slitaz:/usr/src/linux-2.6.30.6-slitaz# ls /lib/firmware/ti_*
/lib/firmware/ti_3410.fw  /lib/firmware/ti_5052.fw
root@slitaz:~# 

6) Load the module and check it is loaded : [thanks Ernia ;-) ]

root@slitaz:~# cd /usr/src/linux-2.6.30.6-slitaz/  depmod -a                           
root@slitaz:~# cd /usr/src/linux-2.6.30.6-slitaz/  modprobe ti_usb_3410_5052
root@slitaz:/usr/src/linux-2.6.33.2-slitaz# lsmod | grep ti_usb
ti_usb_3410_5052       16567  0 
usbserial              22032  1 ti_usb_3410_5052
root@slitaz:/usr/src/linux-2.6.33.2-slitaz#

7) Load automatically the module at boot time:
Edit /etc/rcS.conf and add ti_usb_3410_5052 to LOAD_MODULES line. Here is the resulting line in /etc/rcS.conf file:

root@slitaz:/usr/src/linux-2.6.33.2-slitaz# cat /etc/rcS.conf | grep LOAD_MODULES
LOAD_MODULES="lp parport parport_pc ti_usb_3410_5052"
root@slitaz:/usr/src/linux-2.6.33.2-slitaz# 

8) Connect the MSP-FET430UIF device from Texas Instrument and make sure the driver mapped the module to the device. The output should be something like:

root@slitaz:/usr/src/linux-2.6.33.2-slitaz# dmesg | tail
usb 1-2.2: device firmware changed
ti_usb_3410_5052: probe of 1-2.2:1.0 failed with error -5
usb 1-2.2: USB disconnect, address 5
usbcore: registered new interface driver ti_usb_3410_5052
ti_usb_3410_5052: v0.9:TI USB 3410/5052 Serial Driver
usb 1-2.2: new full speed USB device using uhci_hcd and address 6
ti_usb_3410_5052 1-2.2:1.0: TI USB 3410 1 port adapter converter detected
ti_usb_3410_5052: probe of 1-2.2:1.0 failed with error -5
ti_usb_3410_5052 1-2.2:2.0: TI USB 3410 1 port adapter converter detected
usb 1-2.2: TI USB 3410 1 port adapter converter now attached to ttyUSB0
root@slitaz:/usr/src/linux-2.6.33.2-slitaz# 

9) Let's finally check that the device really exists:

root@slitaz:/usr/src/linux-2.6.33.2-slitaz# ls /dev/ttyUSB0 
/dev/ttyUSB0
root@slitaz:/usr/src/linux-2.6.33.2-slitaz# 

Here you are!
Now be ready to play with Texas Instrument's MSP430 familly.

Cheers.

Hi,
Finally I was able to clone the wok. Now I am back with the initial need of adding the "ti_usb_3410_5052" module in my kernel.

Here are the requested steps for compiling the kernel using the wok. For those interested by a solution without the wok, please check this out: http://forum.slitaz.org/index.php/discussion/817/solved-how-to-make-new-kernel-module-available-without-the-wok/#Item_4.

Let's start:
0) Some tools are needed:

root@slitaz:~# tazpkg get-install slitaz-toolchain
root@slitaz:~# tazpkg get-install ncurses-dev
root@slitaz:~# tazpkg get-install perl
root@slitaz:~# tazpkg get-install zlib-dev
root@slitaz:~# tazpkg get-install mercurial

1) Because not enough space on my /home partition, I had to change default directory. I use "/my_wok/slitaz/wok" instead of "/home/slitaz/wok" (do not use /tmp directory as it is cleaned on every reboot....):

root@slitaz:~# cat /etc/tazwok.conf 
...
# Wok directory/tree to find receipts and build packages.
# By default on SliTaz the directory is /home/slitaz/wok.
#WOK="/home/slitaz/wok"
WOK="/my_wok/slitaz/wok"

# The path to the sources tarballs of the binaries packages.
#SOURCES_REPOSITORY="/home/slitaz/src"
SOURCES_REPOSITORY="/my_wok/slitaz/src"

# This path set the binaries packages repository. It's where all
# the gen *.tazpkg will be stored when using gen-repository command.
#PACKAGES_REPOSITORY="/home/slitaz/packages"
PACKAGES_REPOSITORY="/my_wok/slitaz/packages"
...

=> don't forget to create the /my_wok/slitaz/wok directory...

2) I launched clonning process:

root@slitaz:~# hg clone http://hg.slitaz.org/wok/ /my_wok/slitaz/wok
requesting all changes
adding changesets
adding manifests
adding file changes
added 5203 changesets with 12638 changes to 3838 files
updating working directory
3339 files updated, 0 files merged, 0 files removed, 0 files unresolved
root@slitaz:~# 

3) As suggest by jozee, I changed the receipt and added "make menuconfig &&":

root@slitaz:~# vi /my_wok/slitaz/wok/linux/receipt 

...
EOT                              
        make mrproper            
        cd Documentation/lguest    
        make lguest || return 1  
        cd ../..                                                                
        cp ../stuff/$PACKAGE-$VERSION-slitaz.config .config
        make oldconfig                                               
        ln .config slitaz/config                                               
        make menuconfig &&                                 
        make bzImage &&                                    
        make modules &&                                    
        make INSTALL_MOD_PATH=$PWD/_pkg modules_install && 
        make INSTALL_HDR_PATH=$PWD/_pkg/usr headers_install &&    
        [ -s arch/x86/boot/bzImage ]                          
}                                                             
...

4) Saved the receipt file.

5) I launched tazwok for linux package:

root@slitaz:~# tazwok cook linux
Checking for build dependencies...

Starting to cook linux...
=============================================Checking for source tarball... 
...
root@slitaz:~# 

6) Unfortunately, we need to make changes in the file drivers/usb/serial/ti_usb_3410_3052.c. There is a little trick to edit the fresh source:
- Look at terminal.
- there is line saying: "Untaring linux-2.6.30.6.tar.bz2... tar: warning: skipping header 'g' "
- wait for this line to disapear (lets the untar process to finish).
- Then stop the cooking with a ctrl-C.

7) Let's make the required changes (as suggested here http://www.embeddedrelated.com/groups/msp430/show/31784.php):

Edit the file:

root@slitaz:~# vi /my_wok/slitaz/wok/linux/linux-2.6.30.6/drivers/usb/serial/ti_usb_3410_5052.c

First change (status = 0x01E; ), arround line 420

                /* 3410 must be reset, 5052 resets itself */
                if (tdev->td_is_3410) {        
                        msleep_interruptible(100);
                        usb_reset_device(dev);                         
                }                                                      
                                                                    
                /*here is the required change.*/        
                //status = -ENODEV;
                status = 0x01E;                                         
                goto free_tdev;                                       

Second one (status = 0xA1B), a few line further :

        /* the second configuration must be set */
        if (dev->actconfig->desc.bConfigurationValue == TI_BOOT_CONFIG) {
                status = usb_driver_set_configuration(dev, TI_ACTIVE_CONFIG);
                /*here is the required change.*/                       
                //status = status ? status : -ENODEV;
                status = 0xA1B;                    
                goto free_tdev;
        }                           

8) save the file

9) Launch cooking process once again. But this time we gonna let it go to the end:

root@slitaz:~# tazwok cook linux
Checking for build dependencies...

Starting to cook linux...
=============================================Checking for source tarball... 
...
...

10) Let's choose the new module we want to add, through the text interface. Go to:
Device Drivers => USB support => USB Serial Converter Support => and then turn on (with character "m") "USB TI 3410/5052 Serial Driver".

Then Click "Exit" many times and exit/save the new config. The cooking process will continues compilling the kernel. Be patient, it took more than 4 hours on my P3-500MHz...

11) rename the actual kernel to vmlinuz-2.6.30.6-slitaz_original:

root@slitaz:~#mv /boot/vmlinuz-2.6.30.6-slitaz /boot/vmlinuz-2.6.30.6-slitaz_original

12) Then install the new kernel:

root@slitaz:~# tazpkg install /my_wok/slitaz/packages/linux-2.6.30.6.tazpkg --forced

Installation of : linux-2.6.30.6

14) reboot and choose the new compiled kernel at grub boot menu

15) check if the ti_usb_3410_5052 module is available:
