Cannot access ram0 in VxWorks 6.7 RTOS through Vxshell

We are using VxWorks 6.7 to build our RTOS. We have enabled RAM Disk in Project configuration. While executing vxshell I can see the disk /ram0. But I cannot access it. How may I access it?

You may want to check if your RAM disk includes a file system.

Please create a post on the Wind River Knowledge Forum for additional support.

I am not able to sign in to Wind River Knowledge Forum. Do I have to create a new account?

Also, regarding RAM disk including file system which components shoud I include from Component configuration?

Off the top of my head, you shouldn’t need more than RAMDISK and DOSFS. I’d also check the RAM disk format options, if any.

Your VxWorks license should entitle you to an account on KF.
