Adapters THE ARM-20 ADAPTER The ARM-20 adapter is included with I-jet. It converts the MIPI-20 I-jet cable to the legacy ARM-20 (0.1 in × 0.1 in pitch) JTAG headers. This is a diagram of the adapter: Figure 5: MIPI-20 to ARM-20 JTAG adapter... - Page 18 JTAG equipment, so that the clock is not advanced until the synchronizing device captured the data. In adaptive clocking mode, I-jet is required to detect an edge on RTCK before changing TCK. In a multi-device JTAG chain, the RTCK output from a device connects to the TCK input of the down-stream device.

Page 19: The Ada-Mipi20-Ti14 Adapter
Table 6: ARM-20 pin definitions The R2 pull-down on pin 17 of the I-jet MIPI20 connector is a signal to the I-jet that a legacy ARM-20 adapter is being used. Other adapters will have different resistors so that I-jet can identify them if needed. A solid GND on this pin means no adapter is being used and the MIPI cable is connected directly between the I-jet and the target board. - Page 20 Adapters The adapter has the MIPI-20 male header on top for connecting the I-jet MIPI-20 cable, and a TI-14-style female header (socket) on the bottom. The TI-14 JTAG header is a 14-pin, double-row, 0.1 in × 0.1 in (2.54 mm × 2.54 mm) pitch connector with a key (plug) in position 6 to prevent misconnections.
