ELECTROSTATIC WARNING

The STR-P711 board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board.

BOARD USE REQUIREMENTS

Cables: The cable you will need depends on the programmer/debugger you use. If you use ARM-JTAG-EW, you will need USB A-B cable, if you use AVR-JTAG, you will need LPT cable; you will also need RS232 cable.

Hardware: Programmer/Debugger ARM-JTAG-EW, ARM-JTAG, or other compatible programming/debugging tool if you work with EW-ARM.

You can use also ARM-USB-OCD, ARM-USB-TINY, ARM-USB-OCD-H, ARM-USB-TINY-H, but we don't offer a project for this board with this programmers.

JTAGThe JTAG connector allows the software debugger to talk via a JTAG (Joint Test Action

Group) port directly to the core. Instructions may be inserted and executed by the core thus allowing STR711F memory to be programmed with code and executed step by step by the host software.
