The board FRDM-KL81Z is produced by NXP semiconductor, it supports a power supply voltage range of 1.71 to 3.6 V. It features a KL81Z, a device boasting up to 128 KB flash and 96 KB SRAM, and numerous analog and digital peripherals. In addition, the FRDM-KL81Z offers a QSPI interface to expand program memory and USB 2.0 Full Speed without requiring an external crystal.
The FRDM-KL81Z hardware is an NXP Freedom development board assembled with the following features:
- Board power select with 3.3 V or 1.8 V MCU operation.
- MKL81Z128VLK7 MCU (96 MHz, 128 KB flash, 96 KB SRAM, 80 LQFP package)
- Accelerometer and magnetometer, FXOS8700CQ.
- Onboard debug circuit: MK20DX128VFM5 OpenSDA with virtual serial port.
- I/O headers for easy access to MCU I/O pins.
- Flexible power supply options: USB, coin cell battery, external source.
- Two TSI(Touch Sensing Interface) touch pads.
- Reset push button.
- Two mechanical push buttons, NMI and LLWU buttons.
- RGB LED.
- Run the command to build the image:
"aos make yts@fremkl81z test=certificate"
- Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
- Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
- Download the program to the target board.
- Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
- If the test case run successfully, you can see all 26 test case run pass.
NOTE: If no frdmkl81z board on your hand, a frdmkl82z board can be used with KL81 SoC on it.
- Initial update (7-20-2018):
Porting the alios to frdmkl81z board, the yts case can run pass on this board.
