You're welcome :-)

It turned out to be a great way to restore the flash without booting
from NFS. I tried that on a TS-7250 but Kyaw Kyaw reported some problems
with his 7200.

Maybe someone at TS can answer this:
1) Is there any reason that loading the 8Mb initrd containing the
complete busybox linux distro should work on a 7250 and not on a 7200?

2) In the reference manual latest version of the reference manual it
says "memory location used is 0x0080_0000 or 0x00600000, for example" on
page 10. Why "0x0080_0000" and not "0x00800000"?

3) Is there any part of the memory that is bound to be better because of
large chunks of contiguous memory?
