Just saw yesterday's discussion about OpenOCD (Cortex-A8) support (for beagle) at IRC
http://www.beagleboard.org/irclogs/index.php?date=2008-06-10#T20:02:52
keesj: Having OpenOCD support for Beagle would be really nice!
However, looking to
http://www.amontec.com/jtagkey-tiny.shtml
I wonder if "All JTAG signals are 5V down to 2.8V tolerant" would be sufficent for Beagle.
I think Beagle needs 1.8V
