|
|
|
|
|
connectors and a Kinetis K66 on board.
|
|
|
|
|
|
|
|
|
|
- Comes with a J-Link Edu Mini for programming and UART console.

boards: convert images to JPEG and reduce image size
The boards folder uses ~142.8 MB, being the largest in the repository.
This is due mostly to board images, which are in most cases not
optimized for web content. This patch tries to address this problem by
converting all pictures to JPEG (quality 75) and by adjusting its size
up to 750 px (the width of the documentation content). Images that
specified a fixed width in rst files are converted down to that value
instead.
With this patch, folder goes down to ~53.5 MB from 142.8 MB (-~63%).
Note that this patch introduces a new set of binary files to git
history, though (bad).
The process has been automated using this quickly crafted Python script:
```python
from pathlib import Path
import re
import subprocess
def process(doc, image, image_jpeg, size):
subprocess.run(
(
f"convert {image}"
"-background white -alpha remove -alpha off -quality 75"
f"-resize {size}\> {image_jpeg}"
),
shell=True,
check=True,
cwd=doc.parent,
)
if image != image_jpeg:
(doc.parent / image).unlink()
for doc in Path(".").glob("boards/**/*.rst"):
with open(doc) as f:
content = ""
image = None
for line in f:
m = re.match(r"^(\s*)\.\. (image|figure):: (.*)$", line)
if m:
if image:
process(doc, image, image_jpeg, size)
image = Path(m.group(3))
if image.suffix not in (".jpg", ".jpeg", ".png"):
content += line
image = None
continue
image_jpeg = image.parent / (image.stem + ".jpg")
size = 750
content += (
f"{m.group(1)}.. {m.group(2)}:: {image_jpeg}\n"
)
elif image:
m = re.match(r"\s*:height:\s*[0-9]+.*$", line)
if m:
continue
m = re.match(r"\s*:width:\s*([0-9]+).*$", line)
if m:
size = min(int(m.group(1)), size)
continue
content += line
if line == "\n":
process(doc, image, image_jpeg, size)
image = None
else:
content += line
with open(doc, "w") as f:
f.write(content)

System Clock
|
|
|
|
|
============
|
|
|
|
|
|
|
|
|
|
The K66F SoC is configured to use the 16 MHz external oscillator on the board
|
|
|
|
|
with the on-chip PLL to generate a 160 MHz system clock.
|
|
|
|
|
|
|
|
|
|
Serial Port
|
|
|
|
|
===========
|
|
|
|
|
|
|
|
|
|
The K66F SoC has six UARTs. LPUART0 is configured for the console, UART0 is labeled Serial 2,
|
|
|
|
|
UART2 is labeled GPS, UART4 is labeled Serial 1. Any of these UARTs may be used as the console by
|
|
|
|
|
overlaying the board device tree.
|
|
|
|
|
|
|
|
|
|
USB
|
|
|
|
|
===
|
|
|
|
|
|
|
|
|
|
The K66F SoC has a USB OTG (USBOTG) controller that supports both
|
|
|
|
|
device and host functions through its micro USB connector (K66F USB).
|
|
|
|
|
Only USB device function is supported in Zephyr at the moment.

|
Programming and Debugging
|
|
|
|
|
*************************
|
|
|
|
|
|
|
|
|
|
Build and flash applications as usual (see :ref:`build_an_application` and
|
|
|
|
|
:ref:`application_run` for more details).
|
|
|
|
|
|
|
|
|
|
Configuring a Debug Probe
|
|
|
|
|
=========================
|
|
|
|
|
|
|
|
|
|
A debug probe is used for both flashing and debugging the board. This board is
|
|
|
|
|
configured by default to use jlink. The board package
|
|
|
|
|
with accessories comes with a jlink mini edu and cable specifically for this board
|
|
|
|
|
along with a usb to uart that connects directly to the jlink mini edu. This is the expected
|
|
|
|
|
default configuration for programming and getting a console.

Configuring a Console
|
|
|
|
|
=====================
|
|
|
|
|
|
|
|
|
|
Use the following settings with your serial terminal of choice (minicom, putty,
|
|
|
|
|
etc.):
|
|
|
|
|
|
|
|
|
|
- Speed: 115200
|
|
|
|
|
- Data: 8 bits
|
|
|
|
|
- Parity: None
|
|
|
|
|
- Stop bits: 1
