Hi Wolfgang,
Unfortunately, at this time, that old version I have on PXA270 board.
Would you inform where can I find the repository of Socket-CAN ?
I use a simple makefile below and put all necessary header files in its
respected place :
(Oh yes, sorry, I used also all header files /include/linux/can/dev.h -
error.h - netlink.h and
/include/linux/can/platform/sja1000.h)
obj-m :=sja1000_isa.o
KERNEL_SRC :=/opt/src/linux-source-2.6.20.18-rt8
PWD :=$(shell pwd)
default:
$(MAKE) ARCH=arm CROSS_COMPILE=arm-linux- -C $(KERNEL_SRC) M=$(PWD)
modules
It produces the sja1000_isa.ko with warnings mentionned in my first email.
Regards,
Michael
