[U-Boot-Users] Simple newbie fs question

[Josiah Allen]

I apologize for this beforehand, but maybe there's a simple answer.  I'm
very new to uboot.

I've gotten myself into a tough spot.  There's a application on my computer
preventing my boot from completing, since it freezes.  I can fix it if I can
just remove/corrupt the guilty file on my file system.  So I stop the boot
and enter into the uboot command line.  I can see the file I want to remove,
but I am not skilled enough to know if/how I can alter it or remove it from
the uboot command line.  I'm using version 1.1.3.

If such a thing is possible I would appreciate instructions.

Thanks.

Sorry, your description is too vague.  Please tell us which architecture 
(PowerPC, ARM, MIPS, etc.), what type of file storage (CompactFlash, 
hard drive etc.), the operating system you're trying to boot and the 
file system type.  How do you 'see' the file that you want to remove?

regards,
Ben

Thanks for the reply.

It's a PowerPC Linux Kernel Image.

It's on a 32 mb flash.

fsinfo says it is type JFFS2.

I can view the file using the 'ls' command.  I can even 'load' it with
fsload.

U-Boot supports only read-only file system access. All you can  do  i
erase the whole JFFS2 file system and re-install from a (clkeaned up)
version.

Bad news.  AFAIK, you can only read the file system or wipe out the 
whole thing.
