Dear experts,
Probably I missed something, but I am confused how the major numbers of the driver are associated with the DM355 IPIPE, AEW, and AF module. I understood from the source code, that the major number is allocated dynamically. But how can I create a corrsponding entry in the /dev directory? Up to now, I did this with the mknod command in the /etc/init.d/rcS. e.g.
mknod -m 666 /dev/dm355_aew c 252 0
mknod -m 666 /dev/dm355_af c 253 0
mknod -m 666 /dev/dm355_ipipe c 254 0
However, because the major numbers are allocated dynamically, the numbers might change, and I end up with a mismatch of major number and dev entry and a crash of my system.
Thus, my questions
- do I have to create a entry in /dev directory for the dynamically allocated IPIPE, AEW, and AF modules?
- if yes, how can I do that other than with mknod in the rcS file?
Any help would be appreciated.
Thanks, Stefan
