Compatibility notes
The adapter might not be automatically detected and powered by older versions of
●
IAR Embedded Workbench for Arm. In such cases, select the Target Power option
on the Project>Options>Debugger>I-jet>Setup page.
The adapter does not supply power to target and therefore does not resume the target
●
power consumption.
When used with the ADA-MIPI20-TI14 and ADA-MIPI20-CTI20 adapters, the
●
EMU0 and EMU1 signals are not connected.
Due to added JTAG signals propagation delays, some target boards might not work
●
at the full 32 MHz JTAG clock speed, so reducing the JTAG speed in C-SPY might
be needed.
The majority of target boards have the SWO signal routed to pin 6 of the target
●
MIPI20 debug connector. In cases when pin 14 is used for SWO, you must move the
0R shunt (marked S1) up from position 3-2 to position 2-1.
The adapter does not support 1.8 V JTAG signals from target. The target JTAG
●
voltage range is limited to 2.5-5 V.
The JTAG interface on the target side automatically adapts to the voltage given on
●
the target VTREF pin (2.5 V-5 V). Because of the isolation barrier, the I-jet side
uses its own voltage, independent of the target voltage. This is for information only
and has no effect on the target JTAG operation.
ETM trace is not supported by this adapter.
●
This adapter cannot be used with I-scope.
