RIoTboard : "sm_test" & "tcrypt" in order to use the CAAM encryption

fmajeric · ‎03-02-2015

Dear All,

I bought an RIoTboard with an iMX6solo embedded processor.

I download on the element14 web site the source code, and compiler on git page:

The source code are from here : http://www.element14.com/community/docs/DOC-68442/l/riotboard-bsp-images-and-tools-download--android...

i.e. :

- BSP Linux ubuntu v3.0.35 : http://downloads.element14.com/downloads/riotboard/Linux/image_SVN2487.zip?COM=RIoTboard

- Mfg Tool : http://downloads.element14.com/downloads/riotboard/Linux/tools_SVN2652.zip?COM=RIoTboard

- Compiler tools from : $git clone git://github.com/embest-tech/fsl-linaro-toolchain.git

I want to use "sm_test.c" and "tcrypt.c" which seem to be kernel modules.

I tried to compile “sm_test.c” with this Makefile :

#

# Makefile for Freescale iMX6solo modules

#

export ARCH=arm

export CROSS_COMPILE=/home/fmajeric/Bureau/Board/Riotboard/Sources/fsl-linaro-toolchain-master/bin/arm-fsl-linux-gnueabi-

#

obj-m := sm_test.o

KDIR := /home/fmajeric/Bureau/Board/Riotboard/Sources/linux-imx/linux-imx-embest_imx_3.0.35_4.0.0

PWD := $(shell pwd)

all:

$(MAKE) -C $(KDIR) M=$(PWD) modules

clean:

$(MAKE) -C $(KDIR) M=$(PWD) clean

But the compiler return me this error :

Also I tried to compile “tcrypt.c” with this Makefile:

#

# Makefile for Freescale iMX6solo modules

#

export ARCH=arm

export CROSS_COMPILE=/home/fmajeric/Bureau/Board/Riotboard/Sources/fsl-linaro-toolchain-master/bin/arm-fsl-linux-gnueabi-

#

obj-m := tcrypt.o

KDIR := /home/fmajeric/Bureau/Board/Riotboard/Sources/linux-imx/linux-imx-embest_imx_3.0.35_4.0.0

PWD := $(shell pwd)

all:

$(MAKE) -C $(KDIR) M=$(PWD) modules

clean:

$(MAKE) -C $(KDIR) M=$(PWD) clean

And it succeed.

I copy the file “tcrypt.ko” on my board.

Try a insmod and I have this error :

root@linaro-ubuntu-desktop:/home/linaro/Dev# ls

tcrypt.ko

root@linaro-ubuntu-desktop:/home/linaro/Dev# lsmod

insmod: error inserting 'tcrypt.ko': -1 Attempting to link in too many shared libraries

Moreover during the u-boot session I’ve set “caam” in bootargs.

So I don’t understand what is wrong.

I think the problem is my kernel version... (3.0.35_4.0.0)

Anybody have a suggestion ?

Cheers,

Fabien.
