Hi, I’ve found OpenOCD useful recently at work. Our debugger hadn’t arrived, so I put together a setup using OpenOCD+AlteraUSBblaster. For that, I thank you.
I am interested with the idea of using OpenOCD+RaspberryPi as a self-contained debugger. (Plug in power, ethernet, JTAG cable and off you go). I see there is already support, and Paul also has an (old) project in Gitorious. However I thought JTAG master on the Pi could be done better than GPIO — using the SPI controller. So here are my questions to the developers: 1) Is there enough interest in using RaspberryPi as the whole debugger? (no host/USB dongle necessary.) 2) Is this even a problem? Do people who use the RaspberryPi feel GPIO bit banging is too slow or am I imagining a non-issue? 3) The BCM2835 SPI controller appears to be flexible enough to use as a JTAG master. The current SPI driver couldn’t accommodate JTAG. If I go about writing a new driver on the Pi, how should the interface look to the application (OOCD specifically). Do you have other JTAG interface that you feel is such a good fit, I could use as an example? (Or your dream JTAG interface…) I look forward to your input.
