Hi,
I am trying to dump the flash (Spansion S29GL128N) on an Ikanos Fusiv
vx160 (Lexra ADI MIPS core), and urjtag segfaults when I try to detect
the flash:

I tried to strace, but it does not say anything when it segfaults.
Any idea how to go further?

"In July 2005, after several failed attempts to legalise software
patents in Europe, the patent establishment changed its strategy.
Instead of explicitly seeking to sanction the patentability of
software, they are now seeking to create a central European patent
court, which would establish and enforce patentability rules in their
favor, without any possibility of correction by competing courts or
democratically elected legislators."
