LTIB for mpc8349itx

[fjpse]

I want to make a hello driver for this platform using LTIB.

First, I execute this commands to get the kernel source and to compile the kernel

./ltib -p kernel -m prep
./ltib -p kernel -m scbuild

Now I get the kernel source in rpm/BUILD/linux

I create a subdir rpm/BUILD/test with two files: test.c (my hello driver) and Makefile (attached with extension  .txt)

To compile the driver, I use LTIB in shell mode:

./ltib -m shell
LTIB>cd rpm/BUILD/test
LTIB>make

But the compiler fail because it can't found <platforms/83xx/mpc8349_itx.h> (this file exist) in the linux kernel source (attached the file result.txt with the output of the make command).

What is the problem? How to build a driver using the LTIB?
Thanks.

result.txt
Makefile.txt
test.c

i tried what you did, let me show you what i got :

if you see what goes wrong . . .
thank you

aurelihein, try the command 'make V=1 ARCH=ppc' in a shell ltib (enter by command './ltib -m shell').

Thanks a lot, the compile is OK.

Now, I have the module nammed test.ko (under rpm/BUILD/test/).

But after the commands : ./ltib -p kernel -m scbuild and ./ltib -p -m scdeploy

this module test.ko is not present in the files : rootfs.ext2.gz.uboot or uImage.

I load this files by tftp to boot (I supposed that you use NFS to boot).

Do you know how to include the module test.ko (under rootfs/lib/module I supposed) ?

Thanks

Mii

aurelihein posted a message indicating how to make it (the second message of this thread), but i don't probe that. (sorry)

At the moment, I`m working with the small-ramfs (saved into flash memory), because I have to do some tests over the platform before beginning the deployment of the system.

I have seen the aurelihein message, but not understand.

My directory /rootfs/lib/modules/2.6.13.4/sources is a link

to /rpm/BUILD/linux-2.6.13.

To use small-ramfs, you must create rootfs.ext2.gz.uboot, I suppose ?

Do you have modified .lkc file to include test.ko in your small-ramfs ?

Thanks for your time.
