hi,
After compiling kernel with new module ti_usb_3410_5210, I am wondering how to make it available for the fresh compiled kernel.

Here are the files *.ko related to ./usb/serial/ after new kernel compilation:


root@slitaz:~# ls /my_wok/slitaz/wok/linux/linux-2.6.30.6/drivers/usb/serial/*ko
/my_wok/slitaz/wok/linux/linux-2.6.30.6/drivers/usb/serial/ch341.ko
/my_wok/slitaz/wok/linux/linux-2.6.30.6/drivers/usb/serial/ftdi_sio.ko
/my_wok/slitaz/wok/linux/linux-2.6.30.6/drivers/usb/serial/option.ko
/my_wok/slitaz/wok/linux/linux-2.6.30.6/drivers/usb/serial/pl2303.ko
/my_wok/slitaz/wok/linux/linux-2.6.30.6/drivers/usb/serial/ti_usb_3410_5052.ko
/my_wok/slitaz/wok/linux/linux-2.6.30.6/drivers/usb/serial/usbserial.ko
root@slitaz:~#

I did installed the fresh compiled kernel with:


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

But not all new modules seem to be loadable (actually only 3 instead of 6 modules):


root@slitaz:~# ls /lib/modules/2.6.30.6-slitaz/kernel/drivers/usb/serial/
ch341.ko.gz      pl2303.ko.gz     usbserial.ko.gz
root@slitaz:~#

Would anyone be so kind to tell me:
- q1) why only 3 modules (ch341.ko.gz, pl2303.ko.gz and usbserial.ko.gz) are available instead of the 6 requested modules (ch341.ko, ftdi_sio.ko, option.ko, pl2303.ko, ti_usb_3410_5052.ko and usbserial.ko)?
- q2) what is the procedure to make those 6 modules available for loading with modprobe?

Thank you for you feedback.

I understand it might not be a very exciting subject, but I really need to solve this.

Any help?
;)

I am guessing you used "tazwok cook linux". If yes, read the output of linux pkg. most likely it must have outputted : "the module selected in .config were not categorized in linux-* pkgs". If your module is there, easiest way is to add it to modules-2.6.30.6.list. Otherwise, read linux-* receipts and edit an existing/make a new receipt to categorize your module.

Hope this helps. Right now, we are busy and time-pressed for 3.0 . Please don't expect more answers :-(

Dear all,
Here are the required steps in order to add module ti_usb_3410_5052 to linux kernel. This solution does not use the wok. If you are interested in a solution using the wok, please check http://forum.slitaz.org/index.php/vanilla/discussion/674.

Let's do it:

0) Make sure we have linux-source files (as root):

root@slitaz:/home/stephane# tazpkg get-install linux-source

1) Go to linux-source directory (as root):

root@slitaz:/home/stephane# 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   <== replace this line
CONFIG_USB_SERIAL_TI=m                 <== with this one

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:/usr/src/linux-2.6.33.2-slitaz# depmod -a                           
root@slitaz:/usr/src/linux-2.6.33.2-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.
Stephane
