[En-Nut-Discussion] Ethernut with CAN-IF

[Huett W.]

Thanks,
HW is not the problem, I've already connected the HW
with corresponding glue logic (Adress decoder,....).

Now I've done first SW steps:
But adding
u_short base_address = 0x8000;
NutRegisterDevice(&devSJA1000, base_address, 0);
to my example program I run into the following link error
C:/ethernut-3.9.8/nutbld/lib\libnutdev.a(sja1000.o)(.text+0x12): In function
`CA
NBufferInit':
: undefined reference to `NutSemInit'
I've already searched several hours but I can not locate the problem.
Everything seems to be fine (Configurator used as SW-manual tells, no
problem
with lib build, compile/link ok if I remove NutRegisterDevice(&devSJA1000,
base_address, 0);
call, take a look on build control files Makefile, etc, ......)
Maybe it's really simple and only a matter of my very small experience.

For any hint thanks in advance.

Best regards

Wolfgang Hütt
