Hi Eric,
yes, from your excerpt of the kernelconfig I can see that you have not
enabled the 485 support in your kernel.
You have to enable it:
Fro your devbpard directory issue the command:
make kernelconfig
in the "Drivers for built in interfaces" you will find the RS-485
support option.
I strongly suggest you to update your vmWare SDK or to download a newer
copy since yours is not supporting the "make kernelconfig" simple command
to modify the kernel options.
Now the SDK (also the vmWare one) is based on subversion and we are at
the release 26. I am not prepared to support any possible intermediate
release of the old SDK so better to be aligned on the last one.
If you need to stick with your release the way to enter in the kernel
option is:
make -C packages/os/linux-2.6 menuconfig
Best regards,
Roberto Asquini
