I was looking over the schematic for my 53qsb and saw that pin 1 and pin2 are running at different voltages. Is this going to be an issue with the arm-usb-ocd? >From the olimex data sheet: "VREF – voltage follower input for the output buffers adjust JTAG signals as per your target board voltage levels" VREF is on pin 1 so I don't think this is an issue, but on the same data sheet they are showing a 0 ohm resister(R45) going from ping 1 to 2. We might need to remove this on our arm-usb-ocd. James
