(www.ftdichip.com) should be used to program the device - the required configuration is shown in Figure 3. It is necessary to first select the chip type, FT232R, in the Chip_Details page. Figure 3: Configuration Settings for FTDI device © Jennic 2010 JN-RM-2056 v1.0...
Page 11: Programming
In order to use the USB Programming Dongle to program the Flash memory device on a remote JN5148-based application board, it is necessary to connect pins 1, 2, 3, 5 and 6 of the dongle board’s J8 connector to the application board. Pin 4 can also be connected, if it is required to power the application board.
