The i.MX23 EVK, on the revision C of the board, is designed to allow the serial JTAG function
and the Debug UART functions to be disconnected from the CPU and used independently to
support the bring up of other prototype boards. To use this feature, the designer must have
available:
-A wire connected to the DEBUG pin of the CPU (E12).
- A wire connected to the PSWITCH pin of the CPU (B3).
- A wire connected to PWM0 (C3).
- A wire connected to PWM1 (D2).
- A wire connected to system ground.

will automatically receive power from the EVK regulators. Any CPU operations at this time will
not affect the JATG/DUART signals. To ensure that the CPU is kept off, the BATTERY
SUPPLY switch (S12) can be moved to the right and any Li-ION battery detached from the
EVK.
The JTAG and UART connections should now work for the attached prototype board in the
same way they work for the EVK CPU.
3.3 Using the EVK to provide JTAG/UART support for
Freescale Semiconductor
Place switch S23 in the right position (TO JP122).
Connect the prototype wires to the EVK as follows:
PWM0 to JP122 Pin 1
PWM1 to JP122 pin 2
DEBUG to JP122 pin 4
PSWITCH to JP122 pin 5
GROUND to JP122 pin 6.
Ensure that 5V wall power is supplied to the board. The UART driver IC and the CPLD
Place the SJTAG DEBUG switch (S22) in the down (TO JP122) position.
