How do I create a ramdisk using QNX4.24?
|
| Solution |
If you are booting from disk, then you need to specify the -r <ramdisk_sz> option to Fsys in your boot image.
Fsys -r 4096 (minimum)
This creates an entry in the namespace called /dev/ram when the machine boots.
Then in your /etc/config/sysinit.<node> file you need to initialize the ramdisk:
dinit /dev/ram
Then mount the ramdisk:
mount /dev/ram /ram |
