Is TCK on JTAG the same speed as CPU clock on a Intel X Scale (ArmV5) PXA270?
I'm probing signals on pads around the CPU and got a waveform like:
But I don't know whether any of this data is JTAG, or just writing to memory or something else. Any idea what this data is?
I think if I can find TCK, TDO/TDI should be somewhere near the same set of pads on the PCB?
