Re: TS 7200 kernel image size

[Lloyd Parkes <lloyd%must-have-coffee.gen.nz@localhost>]

I have an open PR about this. I gave up stripping things out of the  
kernel and just adjusted the reserved portion of Flash. The reserved  
portion holds the initial boot code and the demo Linux root file  
system. We only need one of those.

The easiest approach appeared to be to fiddle the directory itself so  
that the reserved section is shorter. RedBoot still isn't always 100%  
happy with this, but that's only when updating the fis directory. I  
ran the following

  mcopy -s 0x607E0000 -d 0x00200000 -l 0x00020000
  x -b 0x200000 -1 -l 32
  mfill -b 0x20001a -p 2 -l 1 -1
  x -b 0x200000 -1 -l 32
  fis write -b 0x00200000 -l 0x00020000 -f 0x607E0000
  fis create -l 0x00160000 -f 0x60100000 -n test
  fis create -b 0x00200000 -e 0x00200000 -r 0x00200000 -l 0x00160000 - 
f 0x60100000 test

Note the two "fis create" commands. This seems to be one of the  
instances where RedBoot is still a bit unhappy. It doesn't seem to  
want to automatically create an entry in the old reserved area when  
copying RAM to Flash. I guess there's something hardcoded. Booting  
never exhibits a problem. This is for an 8MB TS7200. Odds are that it  
will do nothing on any other TS7xxx, but it might catch fire and burn  
your home/office down.

Cheers,
