  • why is ftdi_layout_init 0x0098 0x008b necessary? (JTAG breaks with simpler values, "JTAG scan chain interrogation failed: all ones")
  • review ftdi_layout_signal nSRST -data 0x0002
  • figure out how to drive POR

POR can be controlled easily with PyFTDI, which is good enough. With OpenOCD it's a mess.
