Death of a JTAG

So with the discrete JTAG cable, it was the same story. "Cable power off" and "timeout". With that and the failure of any other tool to work around the STR9's peculiar JTAG daisychaining, it looks like this $67 experiment is bound for the gadget graveyard.

The remaining options are expensive.

1) Buy a commercial programmer for the STR9: ($75) No guarantee of success. Only works with ST and their Win 2000 single CPU debugger.

2) Buy a Gumstix. ($150 + Hirose connector cost) Guaranteed to work.

3) Try to get a discounted AT91SAM board from the day job.

4) Try again to run the STR9 in a crippled mode, without using the proprietary JTAG commands to optimize it.

With other projects in need of faster processors, the Gumstix doesn't meet our goal of a cheap, powerful processing solution for everyone. The STR9 isn't fun either, with its bird nest of undocumented codes.

Been getting better at making sonic booms with the copter. One thing 3D pilots don't capitalize on is the creation of sonic booms due to blade tips approaching the speed of sound. The trick is to enter rapid descent with low throttle and fast forward movement. It can get amazingly loud, almost like a blackhawk.
