insmod: can't insert 'sun4i-gpio.ko': invalid module format

I know that this error is because of my kernel version is not the one on which I am running the insmod command, but I don't know what to do to sort out this problem?

You have already pinned down the issue by yourself...

kernel modules are specific to a kernel build, so make sure you insmod modules respective to kernel you are running.

Dear tinypoodle,

What is your opinion about the following lines ?

Thank you.

I run dmesg and uname -a commands and the results are :

Hi persian
It's rejecting the module because its version does not match the version of your kernel.
sun4i_gpio version=3.0.42 ARMv7
kernel version=3.0.42 #3 PREEMPT

I removed the attachment from your previous post. Forum rules forbid the attachment of binaries.

Appears that gpio could be made into a loadable module with existing kernel. I did such.
However, enabling spi requires a new kernel. Therefore your issue.
I assume that you built a new kernel, so next step is to make it Allwinner loadable with mkimage.

You can import u-boot-tools, loadsce u-boot-tools to get mkimage.
Then from your linux source directory

make uImage

Finally copy uImage to sdcard to test boot. Then try insmod your new modules.

[persian]

Dear Roberts,

Thank you, for your effective replies to my questions.

I replaced the [.config] file with [a10Core-kernel-3.0.42.config] and make the uImage successfully and then boot the TC linux from uSD with it.

Also I make a new script.bin for GPIO support (but not for SPI because I don't know how to do it).

Now GPIO attached and work correctly, but when I reboot Marsboard the GPIO disappear!

How can I establish the GPIO for ever ?
I tested the modprobe but It did not have any permanent effect after insmod (and before insmod it make  "not found in modules.dep" error).

Also when I run insmod command for spi_sunxi.ko, I get the following error:

root@box:~# insmod /mnt/mmcblk0p2/My_Added_Modules/lib/modules/3.0.42/kernel/drivers/spi/spi_sunxi.ko
Segmentation fault

The dmesg command report the following error:

I am not knowledgable on GPIO and SPI as these have more to do with the maker crowd and are not needed for desktop. 

You don't have any spi devices.
See: ls -l /dev/spi*

As far as your question about rebooting:
One step at a time. First be sure the module works then you can make a simple sce for them that will load upon boot.

[persian]

Dear Roberts,

I configured the script.bin for GPIO and SPI .

GPIO module works fine but I must run insmod every time I reboot the Marsboard.

I don't know how to make a loadable sce for boot time.

Also the insmod of SPI module makes Segmentation fault error.

My SPI settings in script.bin are as follow:

[spi0_para]
spi_used = 1
spi_cs_bitmap = 1
spi_cs0 = port:PI10<3><default><default><default>
spi_sclk = port:PI11<3><default><default><default>
spi_mosi = port:PI12<3><default><default><default>
spi_miso = port:PI13<3><default><default><default>

spi_miso = port:PA03<4><default><default><default>

Thank you for your helps.

There are many changes in this area with newer kernel. Should be worth investigating, e.g.
CONFIG_SPI_SPIDEV

Dear friends;

Hi,

Today my import did not work and it exit by no error!

When I traced the /usr/bin/import script file, I found that the first wget command with the following parameters return an error:

The line:
      wget -O /tmp/.depfile -cq "$IMPORTMIRROR"/PKGADDDEPS 2"
with the final content:
      wget -O /tmp/.depfile -cq http://repo.tinycorelinux.net/5.x/import/PKGADDDEPS 2

Returned message:
      wget: server returned error: HTTP/1.1 416 Requested Range Not Satisfiable

What's wrong ?

Also I need a command like lsusb but I don't find it.

Please help me about these problems.

Thank you.

[roberts]

Make sure your /tmp directory is writable by user tc.

[persian]

Dear Roberts,

The TC user permission is OK.

I tested it by creating a text file with the following command:
   tc@box:/tmp$ nano test.txt


The problem solved, I think it's an Internet problem.

What about lsusb command ?

Thanks

[roberts]

Google search of "wheezy lsusb" reveals: http://packages.debian.org/wheezy/usbutils

Dear Roberts

Thank you for your reply to my questions.

I attached a A4-Tech model: PK-760E webcam to my Marsboard and the board recognized it as follow with lsbusb command:

Bus 004 Device 003: ID 0ac8:3450 Z-Star Microelectronics Corp.

The command ls /dev | grep video returned blank and I can not run uvccapture, mplayer or webcam application for using webcam.

I googled but I did not find a detail instructions for installing webcam device driver for A4-Tech webcam.

Would you please help me about this problem for Tinycore linux ?

Thank you again.

[roberts]

Likely you need a module. If you are using 3.0.42, as currently provided, then the modules can be found here:

Dear Roberts,

Hi,

The flwm_topside and wbar do not run with new TCL (a10Core-130904.img.gz) on my Marsboard.

I get many errors for udev on startup and X desktop server error on HDMI screen and also the following error on putty terminal.
