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.
