The USB Programming Dongle provides a simple solution for programming a Flash memory device on a JN51XX-based application board using the standard Jennic JN51xx Flash Programmer tool. It's based on the Jennic reference design JN-RD-6021.
This is the recommended tool for re-programming rhe flash memory in the AP-310, AP-330 and AP-350 Gateways.
This USB Programming Dongle replaces the FTDI cable and allows for connection to a physically smaller 6-pin connector, therefore allowing the easy development of application boards where space is critical. In addition to the smaller connector, the requirement for switches on the reset and SPIMISO line is removed, which saves further space.
A secondary use of this programming dongle is to allow UART communication during application development, such as to provide debug messages.
