Kernel and Filesystem Configuration
The uClinux 2.0 kernel must have the digital I/O option compiled for proper operation. These options will be set
using the kernel configuration
cd /opt/uClinux/linux
make menuconfig
Using this main menu, under Character Devices the following must be selected
Digital IO Character Device
After saving your configuration changes, use the following commands in the same directory to complete
compilation of your kernel.
make clean
make dep
make
Now, check if the node for the digital I/O character device exists.
cd /opt/fs/romdisk/dev
If io1 exists in this directory, then continue to create the new image in the next step. If it does not exist, please
refer to Appendix A for further instructions.
Next a combined image of the new kernel and filesystem is to be created.
cd /opt/fs
make clean
make
Then use imagez.bin and run loader on the module to write in the filesystem and kernel. Please refer to the
User’s Manual for details on running loader. The dimmPCI module is now configured for digital I/O.
