Hello all,
I am having a problem during boot concerning VFS (see the kernel output
below).
I have read several posts on this subject but I haven't been able to
find the information that I need.
(Note that I'm porting uClinux to a new architecture (The Cortus APS3
processor)).
Could someone point me to the appropriate docs or suggest how to
proceed, please ?
Thanks in advance.
