Hello,

on my project we will boot QNX 6.5 from NAND flash. Also the application is stored on
NAND in the ETFS partition.

For a test I have written the IPL/IFS at the beginning of the NAND memory with a 
programmer tool. Then I started the system and on the command line I created a ETFS 
structure on the NAND with a raw partition of 16MB.

So far everything works fine - I can boot from NAND and I have my /fs/etfs mount for 
my application.

My question:
How can I update my IPL/IFS? From Google search I suspect that etfsctl can be used for
this but I was not able to find a crisp explanation how to do it. 

What I have is my IPL/IFS binary and what I need is to program it to the beginning of my 
NAND including bad-block skipping. 

The IPL itself does reside in the first block which is considered to be free of bad blocks but 
the IFS (4MB) is not. I saw in my BSP that the IPL is able to skip bad blocks so everything
makes basically sense - the missing thing is the update.

Thanks for your advice,
- Stefan
