Hello,
The following is from a customer having difficulty writing a
device driver. As a form of troubleshooting, he used the ed100 example
provided in /usr/examples/devdriver and is STILL encountering problems
loading the driver.
Looks to me like he is following the steps outlined in the Device
Driver Tutorial...Can someone help?
Thanks,
Donna

Donna,
The following are the commands used to create a new kernel
for ED100.
mkdir /usr/sys/io/ED100
cd /usr/sys/io/ED100
cp /usr/examples/devdriver/ed100/edpseudo.c .
cp /usr/examples/devdriver/ed100/edpseudoreg.h .
cp /usr/examples/devdriver/ed100/files .
cd /usr/sys/conf
vi BINARY.list
i
/usr/sys/io/ED100:
:wq
cd /usr/sys/io/ED100
cp /usr/examples/devdriver/ed100/sysconfigtab .
cd /usr/sys/conf
./sourceconfig BINARY
cd /usr/sys/BINARY
make ed.mod
cd /usr/sys/conf
doconfig
- kernel configuration name : ED100DRV
- select no new kernel options
cd /usr/sys/io/ED100
sysconfigdb -a -f sysconfigtab ed
cd /usr/sys/conf
vi ED100DRV.list
i
/usr/sys/io/ED100:
:wq
cd /usr/sys/conf
doconfig -c ED100DRV
- kernel configuration name : ED100DRV
- select no new kernel options
- Edit configuration No
cp /usr/sys/ED100DRV/vmunix /vmunix
cd /
shutdown -h now
>>> boot -fi "vmunix"

Hi, Donna.
You did not mention which version of Digital UNIX this is. There
were a couple of small bugs in edpseudo.c that caused a couple of
minor problems. I'll email you a fixed version.
From what you have shown in .0, there is very little indication
of exactly what problem the customer is having. The following command
will give us a lot more to go on:
# sysconfig -v -c edpseudo
And, then post what gets printed in the console/dxconsole. Or, it might
be a better idea to have the customer send you a detailed description
of the problems they are having and post that here.
Best Regards,
