Hi,
I recently switched from the Montavista kernel to the GIT kernel. I need to
rebuild cmemk.ko and dsplinkk.ko
with the GIT kernel. When I build cmemk.ko, I get undefined references to
class_simple_*:
# make
make -C

When I load cmemk.ko, I get errors for those undefined references:
# insmod cmemk.ko phys_start=0x87800000 phys_end=0x88000000
pools=1x3145728,3x829440,1x61440,1x10240

cmemk: Unknown symbol class_simple_device_remove
cmemk: Unknown symbol class_simple_create
insmod: cannot insert `cmemk.ko': Unknown symbol in module (-1): No such file
or directory
I'm using the latest GIT kernel (2.6.20-omap1) and dvevm 1.10. I haven't tried
compiling dsplinkk.ko yet. Anyone has this same problem?
Am I doing something wrong? Thanks.
Regards,
Andy
