hi

how it is possible to upgrade s3c2440camera device driver for kernel
mini2440(2.6.29.4) ?

Well you need to adapt camera code for kernel which you need. Lot of
changes should be there.

majid

2010-11-15 11:23:33

It has compiled and built.
What files should be replaced or modified in mini2440?

open-nandra

2010-11-15 11:29:21

If you have builded module just include to kernel and use.

I did but

[root@FriendlyARM /]# cd sdcard
[root@FriendlyARM /sdcard]# ls
mjpg-streamer     s3c2440camera.ko  test_capture
[root@FriendlyARM /sdcard]# chmod u+x s3c2440camera.ko 
[root@FriendlyARM /sdcard]# chmod u+x test_capture 
[root@FriendlyARM /sdcard]# insmod s3c2440camera.ko 
[root@FriendlyARM /sdcard]# ./test_capture 
./test_capture: line 1: syntax error: "(" unexpected
[root@FriendlyARM /sdcard]# 


I build with 2.6.32 and mini2440 is 2.6.29.4 version.

open-nandra

2010-11-15 11:49:24

Test capture has some config file? If yes please check it.

majid

2010-11-15 11:58:08

no, It has only a makefile

open-nandra

2010-11-15 12:08:10

Well I try on my board works fine:
./test_capture 
Usage:./test_capture <device> <width> <height> <output_base> [number of
frames]

Check if you compile correctly.

majid

2010-11-15 12:33:54

kindly, what is your host kernel version and mini2440 kernel version ?
could you please send me test_capture and s3c2440camera.ko files.

open-nandra

2010-11-15 12:48:08

Attachment: driver.tar.gz (85.98 KB)

Sure! In attachment. I use 2.6.32-rc8.

your file does not work on my mini2440(2.6.29.4)

[root@FriendlyARM /sdcard]# chmod u+x s3c2440camera.ko 
[root@FriendlyARM /sdcard]# insmod s3c2440camera.ko 
insmod: cannot insert 's3c2440camera.ko': invalid module format
[root@FriendlyARM /sdcard]# chmod u+x test_capture
[root@FriendlyARM /sdcard]# ./test_capture
-sh: ./test_capture: not found
[root@FriendlyARM /sdcard]#

open-nandra

2010-11-15 13:28:38

For sure you can't load module compiled for 2.6.32 to 2.6.29.

majid

2010-11-16 11:37:46

I just updated mini2440-128 with vivi,zImage_t35 & root_gtopia.img (just
downloaded from friendlyarm)


but still the problem exist

[root@FriendlyARM /]# chmod u+x s3c2440camera.ko 
[root@FriendlyARM /]# insmod s3c2440camera.ko 
insmod: cannot insert 's3c2440camera.ko': invalid module format

do you use original image or have had modification on you mini2440 files?

majid

2010-11-16 11:39:05

[the uploaded images & binaries are latest version]

majid

2010-11-16 11:41:29

{and I use FileZilla3 in binary transfer format; size of transferred files
from pc to mini2440 are the same}

Hi

Are you sure you compiled the module with the rigth Linux kernel version ? 
Run objdump and verify if the generated code is ARM. You may be compiling
the module with the gcc for Intel instead of the ARM cross compile.

Your module is being created with Intel code. Check the instalation of your
cross compile. check also if the CC variavel is set to arm-linux-gcc.
Check the PATH variavel and see if has included your cross compile path.

this objdump info of "s3c2440camera.ko" from
"code.google.com/p/s3c2440camera/" that can be successfully insmod in my

how can we find that it is for arm9 ?

I found that test_capture is in known (not ARM!) format.

but as you see I defined paths and exported them

Marcio Lima

You should use arm-linux-objdump but the result "architeture UNKNOWN" from
the objdump says that the code maybe ARM.
