Check if digital I/O character device exists:
cd /opt/fs/romdisk/dev
ls
Does io1 node exist?
In the current /opt/fs/romdisk/dev
directory, create the digital I/O character
device node:
mknod io1 c 123 1
Generate new image:
cd /opt/fs/
make clean
make
Run loader on the dimmPCI module
using the new image
NO
YES
be created. Create the node by doing the following as root, where 123 is the major number and 1 the minor
number of the character device io1.
mknod io1 c 123 1
After the correct node is created, then continue with compiling the kernel and filesystem image. Below is the
modified flowchart including the extra step of creating the digital I/O character device node.
NOTE A: Creating a node for the character device
Since the node for the digital I/O device does not exist in the /opt/fs/romdisk/dev directory, it needs to
