Thanks for your concern. I have wanted a long time now to verify that my target is Ok. That is is why I made some new efforts with my wiggler clone. In a post some days ago I described that this test gave the same disappointing result, reading nothing but zeros.
I had hoped to borrow a BDI2000 from my job over the weekend but as usual it's occupied in a project for some time and I don't know when I can get access to it. I don't want to disturb my colleagues work. I also have two AVR CAN128 boards with JTAG which might be used to verify that the two interfaces can at least scan the JTAG chain but the connector layout is different and is take some time to get those boards powered properly. Nor am I sure that the JTAG interface is internally enabled on the processors. So there are some problems ahead with that test too. I also started to doubt that openocd actually could work with the LPC2148 since Macraigor OCDCommander seems to be working at least with the wiggler clone. And it is strange that proprietary drivers seems to be the involved your setup. I might give a shot with the AVR boards anyway. Any tips on how to run openocd properly without any particular target processor and just scan the JTAG chain is welcome.
