Hi,

--- Quote Start ---

What linker script are you referring to? I do not see any links to the root file system.

Please search the file 'vmlinux.lds' or 'vmlimux.lds.S'. It's the linker script, and you will find the linking position of 'init.ramfs'.

I also tried uploading the vmlinux file to the FPGA but it gives the same error message as before.

It's quite natural when your kernel does not include 'init.ramfs'. The files zImage etc. are only compressed ones of 'vmlinux'.

Has anyone built the latest version of uClinux for NIOS2 and has it working?

At least, the maintainers do it. And of course, you select 'Initial RAM filesystem' in the menuconfig like 


─ General setup -->
       Create deprecated sysfs layout for older userspace tools 
       Kernel->user space relay support (formerly relayfs)   
       Namespaces support                                   
      
 Initial RAM filesystem and RAM disk (initramfs/initrd) suppor 
      ()    Initramfs source file(s)                          
      
   Support initial ramdisks compressed using gzip   
         Support initial ramdisks compressed using bzip2   
         Support initial ramdisks compressed using LZMA
