Re: [microblaze-uclinux] Sysace flash and read only CRAMFS

[Jalil Boukhobza <boukhobza@xxxxxxxxxxxxx>]

Hi John,
Thanks for the hints, here is what I've done:


# mount ./xsysacea /home                                                                  
VFS: Can't find ext3 filesystem on dev xsa.                                               
VFS: Can't find an ext2 filesystem on dev xsa.                                            
cramfs: wrong magic                                                                       
FAT: invalid media value (0x01)                                                           
VFS: Can't find a valid FAT filesystem on dev xsa.                                        
FAT: invalid media value (0x01)                                                           
VFS: Can't find a valid FAT filesystem on dev xsa.                                        
VFS: Can't find a romfs filesystem on dev xsa.                                            
mount: Mounting /dev/xsysacea on /home failed: Invalid argument                           
# mount -t ext2 ./xsysacea /home                                                          
VFS: Can't find an ext2 filesystem on dev xsa.                                            
mount: Mounting /dev/xsysacea on /home failed: Invalid argument                           
# mount -t ext2 ./xsysacea1 /home                                                         
EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended                     
#

The first mount didn't work (don't know why), but it did on the numbered xsysace s.
For information, I used the busybox mount command.

Thanks for your quick answers

As you can see, the flash memory seem to be recognized as it gives the good capacity, but I can not find the xsa1in the /dev:
    

Here's a clue:

  

xsysacea
xsysacea1
xsysacea10
xsysacea11
    

...

or about 10 of them!

The device node is /dev/xsysacea*, not xsa

If you repeat your experiment with the correct name, I think you will
have more success.

Regards,

John
