yes, low = target continuously in reset. I tried both srst_only and none, but I did not pull out the 'scope, because it worked with disconnected reset line. > > Any hints where to look?

The bitstream from the URL in the config file did not work at all (readback always '1'), so I took the one from the busblaster SVN. Also, I had to use urjtag - flashing from openocd did not work at all (I can provide traces if someone is interested, but I wanted to get debugging running first). BTW: the OpenOCD config files seem to use the wrong device ID - at least my board has 0x0403/0x8878, although I am not sure if this is standard or not. cu Michael ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
