USB Programming Dongle
Reference Manual
3 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.
The JN51xx Flash programmer can then be used to program the Flash device – see
the
JN51xx Flash Programmer User Guide (JN-UG-3007)
. This programming utility
will place the JN5148 into its programming mode by manipulating MISO and
RESETN on J8. It will then download the program to the Flash device and then reset
the JN5148, causing the application to be loaded and executed.
