Thanks for the feedback. What I'm seeing is all relevant pp outputs (d0-d7, nStrobe, nAutoLF, nInt, nSel) high except nSel (EN_JTAG). This makes sense as EN_JTAG is active low, and D4 high enables the power supply. Then I see both TMS and TCLK go low for 160 us. I don't see activity on any other signals. It is puzzling that it works for you, and yet it is not even close to working here. I was hoping to avoid installing the windows-based tools, but I have to get some code up and running this week. Thanks again for your efforts. BTW, would you be interested in patches that would hopefully enhance the documentation? In particular, I'm thinking of the installation instructions. I'm familiar with CVS, so if you were comfortable with giving me commit access, I could do that instead. galen
