|

Several board ports are available for this higher end, NXP
|
|
Cortex-M4F part:
|
|
|
|
**NXG Technologies LPC4330-Xplorer**. This NuttX port is for the
|
|
LPC4330-Xplorer board from NGX Technologies featuring the NXP
|
|
LPC4330FET100 MCU. See the `NXG
|
|
website <http://shop.ngxtechnologies.com/product_info.php?cPath=21_37&products_id=104>`__
|
|
for further information about this board.
|
|
|
|
- **STATUS:** Refer to the NuttX board
|
|
`README <https://github.com/apache/nuttx/blob/master/boards/arm/lpc43xx/lpc4330-xplorer/README.txt>`__
|
|
file for more detailed information about this port.
|
|
|
|
- **NuttX-6.20** The basic LPC4330-Xplorer port is complete. The basic
|
|
NuttShell (NSH) configuration is present and fully verified. This
|
|
includes verified support for: SYSTICK system time, pin and GPIO
|
|
configuration, and a serial console.
|
|
|
|
**NXP/Embest LPC4357-EVB**. This NuttX port is for the LPC4357-EVB from
|
|
NXP/Embest featuring the NXP LPC4357FET256 MCU. The LPC4357 differs from
|
|
the LPC4330 primarily in that it includes 1024KiB of on-chip NOR FLASH.
|
|
See the `NXP
|
|
website <http://www.nxp.com/news/news-archive/2013/nxp-development-kit-based-on-the-dual-core-lpc4357-microcontroller.html>`__
|
|
for more detailed information about the LPC4357 and the LPC4357-EVB.
|
|
|
|
- **STATUS:** Refer to the NuttX board
|
|
`README <https://github.com/apache/nuttx/blob/master/boards/arm/lpc43xx/lpc4357-evb/README.txt>`__
|
|
file for more detailed information about this port.
|
|
|
|
- **NuttX-7.6**. The basic port is was contributed by Toby Duckworth.
|
|
This port leverages from the LPC4330-Xplorer port (and, as of this
|
|
writing, still requires some clean up of the technical discussion in
|
|
some files). The basic NuttShell (NSH) configuration is present and
|
|
has been verified. Support is generally the same as for the
|
|
LPC4330-Xplorer as discussed above.
|
|
|
|
**NXP LPC4370-Link2**. This is the NuttX port to the NXP LPC4370-Link2
|
|
development board featuring the NXP LPC4370FET100 MCU.
|
|
|
|
- **STATUS:** Refer to the NuttX board
|
|
`README <https://github.com/apache/nuttx/blob/master/boards/arm/lpc43xx/lpc4370-link2/README.txt>`__
|
|
file for more detailed information about this port.
|
|
|
|
- **NuttX-7.12** The NXP LPC4370-Link2 port is was contributed by Lok
|
|
Tep and first released in NuttX-7.12.
|
|
|
|
**WaveShare LPC4337-WS**. This is the NuttX port to the WaveShare
|
|
LPC4337-WS development board featuring the NXP LPC4337JBD144 MCU.
|
|
|
|
- **STATUS:** Refer to the NuttX board
|
|
`README <https://github.com/apache/nuttx/blob/master/boards/arm/lpc43xx/lpc4337-ws/README.txt>`__
|
|
file for more detailed information about this port.
|
|
|
|
- **NuttX-7.14** The NXP WaveShare LPC4337-WS port is was contributed
|
|
by Lok Tep and first released in NuttX-7.14.
|
|
|
|
- **NuttX-7.16** Support for the LPC4337JET100 chip was contribed by
|
|
Alexander Vasiljev. Alexander also contributed an LPC43xx AES driver
|
|
available in NuttX-7.16.
|
|
|
|
**Driver Status**.
|
|
|
|
- **NuttX-6.20** Several drivers have been copied from the related
|
|
GPDMA, I2C, SPI, and SSP. The registers for these blocks are the same
|
|
in both the LPC43xx and the LPC17xx and they should integrate into
|
|
the LPC43xx very easily by simply adapting the clocking and pin
|
|
configuration logic.
|
|
|
|
Other LPC17xx drivers were not brought into the LPC43xx port because
|
|
these peripherals have been completely redesigned: CAN, Ethernet, USB
|
|
device, and USB host.
|
|
|
|
So then there is no support for the following LPC43xx peripherals:
|
|
SD/MMC, EMC, USB0,USB1, Ethernet, LCD, SCT, Timers 0-3, MCPWM, QEI,
|
|
Alarm timer, WWDT, RTC, Event monitor, and CAN.
|
|
|
|
Some of these can be leveraged from other MCUs that appear to support
|
|
the same peripheral IP:
|
|
|
|
- The LPC43xx USB0 peripheral appears to be the same as the USB OTG
|
|
peripheral for the LPC31xx. The LPC31xx USB0 device-side driver
|
|
has been copied from the LPC31xx port but also integration into
|
|
the LPC43xx (clocking and pin configuration). It should be
|
|
possible to complete porting of this LPC31xx driver with a small
|
|
porting effort.
|
|
- The Ethernet block looks to be based on the same IP as the STM32
|
|
Ethernet and, as a result, it should be possible to leverage the
|
|
NuttX STM32 Ethernet driver with a little more effort.
|
|
|
|
- **NuttX-6.21** Added support for a SPIFI block driver and for RS-485
|
|
option to the serial driver.
|
|
|
|
- **NuttX-7.17** EMC support was extended to include support SDRAM by
|
|
Vytautas Lukenska.
|
|
|
|
- **NuttX-7.23** A CAN driver was contributed by Alexander Vasiljev in
|
|
NuttX-7.23.
|
|
|
|
- **NuttX-7.24** RTC and Windowed Watchdog Timer (WWDT) drivers were
|
|
leveraged from the LPC17 and contributed by Gintaras Drukteinis.
|
|
Leveraged the LPC54xx SD/MMC to the LPC43xx. There are still
|
|
remaining issues with the SD/MMC driver and it is not yet functional.
