SP6: Debug Interfaces
There are two debug interface connectors available:
J10 – this is a Cortex Debug connector. It is a 2x5 pos, 50 mil pitch connector without a
shroud. Be careful when inserting the debug probe cable. Position 1 is in specifically marked
on the PCB silkscreen. It is located in the lower right corner, see Figure 19 below.
The connector supports both the SWD and JTAG interfaces.
J11 – this is an ARM Debug connector. It is a 2x10 pos, 100 mil pitch connector with shroud.
Both connector are defined and supports both the SWD and JTAG type of debug interfaces.
Note that in order to enable the JTAG/SWD interface on the i.MX RT1062, JP5 shall
not
be
shorted/inserted. This jumper is for future enhancement and other MCUs.
Some debug probes allow control of pin 7 on J10 (pin 11 on J11) to force the target processor (i.MX
RT, in this case) into ISP mode. Short JP9 if the debug probe supports this feature.
Figure 19 – Debug Interfaces and ISP Enable Control
Note that due to the powering sequencing requirements on i.MX RT family, the debug probe
I/O voltage
MUST
follow the i.MX RT I/O voltage.
The debug adapter must not drive any output higher than the Vcc/Vref voltage (and if that
voltage is zero, then the debug adapter must not drive any output signal). Vcc/Vref is pin 1
on both J10 and J11.
Make sure the debug probe does not have a fixed output voltage, but rather follow Vcc/Vref.
If using LPC-Link2 as debug interface, make sure there is
NO
jumper inserted in JP2 (on the
LPC-Link2).

SJ2
1-2 pos (default): Connects pin JTAG_TDO to pin 6 of J10.
2-3 pos: Connect pin GPIO_B0_13 to pin 6 of J10 (SWO pin)
ISP Enable Control
JP9 - shall not be inserted as default. Only if debug probe
supports ISP enable control.
ISP Enable Jumper
J7 - in parallel over SW1, short to force i.MX RT into ISP mode.
Note: Cannot be inserted when executing downloaded application.
