4.4.3. JTAG connectors of Blackfin processor.
To debug your own Blackfin software on the E-502 board, you should use one of the
JTAG- emulators from Analog Devices: ADZS-USB-ICE, ADZS-HPUSB-ICE or
ADZS-ICE-100B with the USB-interface. They differ significantly with USB transfer rate and
price. You can get information on these devices on the manufacturer's website
The board has a JTAG connector,
The operation of attaching and detaching the JTAG-emulator connector should be done in
!
the de-energized state of both devices.
Do not connect the JTAG connector to other devices which are not specified in this chapter.

4.4.4. Connectors JTAG and UART0 of the ARM controller LPC-4333 (LPC-
4337).
To debug your own Blackfin software on the board, you probably will not need to modify the
ARM-controller software that performs the interface function E-502. However, for advanced users
such a modification is possible, for example, in order to use the UART0 ARM port for any interface
functions.
It is also shown on
UART0 ARM interface (the location of the connectors on
position in the E-502).
The TXD and RXD signals of the UART0 interface have an internal pull-up to 3.3V by resistors
of 10 kΩ.
The operation of connection and disconnection the JTAG-emulator and UART0 connectors
should be done in the de-energized state of the connected devices.
