@brief Support for the QN9080DK base board.
|
||
|
|
|
||
|
|
### General information
|
||
|
|
|
||
|
|
The QN9080DK is the developer board reference from NXP for the QN908x CPUs.
|
||
|
|
The developer kit comes with two boards: a larger PCB with a QFN "module"
|
||
|
|
including a QN9080DHN soldered onto it, altogether referred as the "base
|
||
|
|
board"; and separately a much smaller USB dongle with another QN9080 cpu.
|
||
|
|
This board module supports the "base board" only, including the definitions
|
||
|
|
of the gpio, buttons and LEDs specific to this board.
|
||
|
|
|
||
|
|
This board packs a few peripherals and many GPIOs:
|
||
|
|
|
||
|
|
* MMA8652FC, a 12-bit accelerometer
|
||
|
|
*
|
||
|
|
|
||
|
|
The board also features a dedicated programmer hardware implemented using NXP's
|
||
|
|
LPC4322, with its dedicated USB port for connecting to a computer on one end
|
||
|
|
and the SWD port and one UART RX/TX pair connected to the QN9080 on the other
|
||
|
|
end. The LPC4322 also has a fast (50 ksps) ADC ADC122S021 connected to a
|
||
|
|
current sense amplifier to monitor the QN9080 current profile directly on
|
||
|
|
the board.
|
||
|
|
|
||

### Flash the board
|
||
|
|
|
||
|
|
The board can be flashed using the internal LPC4322 JTAG/SWD debugger or an
|
||
|
|
external debugger connected to P1, selected using JP2.
|
||
|
|
|
||
|
|
OpenOCD support for the QN908x is experimental and available as pending
|
||
|
|
[patch](http://openocd.zylin.com/#/c/5584/).
