|
(6 x ARM Cortex-M4)
|

Support for the CXD56\ *xx* was
|
|
|
|
|
|
introduced by Nobuto Kobayashi in NuttX-7.30.
|
|
|
|
|
|
|
|
|
|
|
|
**Sony Spresence**. Spresense is a compact development board based on
|
|
|
|
|
|
Sony’s power-efficient multicore microcontroller CXD5602. Basic support
|
|
|
|
|
|
for the Sony Spresense board was included in the contribution of Nobuto
|
|
|
|
|
|
Kobayashi in NuttX-7.30. *NOTE*: That was an initial, bare bones basic
|
|
|
|
|
|
Spresense port sufficient for running a NuttShell (NSH) and should not
|
|
|
|
|
|
be confused with the full Spresence SDK offered from Sony. Since then
|
|
|
|
|
|
there has been much development of the NuttX CXD56xx port.
|
|
|
|
|
|
|
|
|
|
|
|
**Features:**
|
|
|
|
|
|
|
|
|
|
|
|
- Integrated GPS: Embedded GNSS with support for GPS, QZSS.
|
|
|
|
|
|
- Hi-res audio output and multi mic inputs" Advanced 192kHz/24 bit
|
|
|
|
|
|
audio codec and amplifier for audio output, and support for up to 8
|
|
|
|
|
|
mic input channels.
|
|
|
|
|
|
- Multicore microcontroller: Spresense is powered by Sony's CXD5602
|
|
|
|
|
|
microcontroller (ARM® Cortex®-M4F × 6 cores), with a clock speed of
|
|
|
|
|
|
156 MHz.
|
|
|
|
|
|
|
|
|
|
|
|
**Driver Status:**
|
|
|
|
|
|
|
|
|
|
|
|
**NuttX-3.31**. In this release, many new architectural features,
|
|
|
|
|
|
peripheral drivers, and board configurations were contributed primarily
|
|
|
|
|
|
through the work of Alin Jerpelea. These new architectural features
|
|
|
|
|
|
include: Inter-core communications, power management, and clock
|
|
|
|
|
|
management. New drivers include: GPIO, PMIC, USB, SDHC, SPI, I2C, DMA,
|
|
|
|
|
|
RTC, PWM, Timers, Watchdog Timer, UID, SCU, ADC, eMMC, Camera CISIF,
|
|
|
|
|
|
GNSS, and others.
|
|
|
|
|
|
|
|
|
|
|
|
**NuttX-8.1**. Alin Jerpelea brought in ten (external) sensor drivers
|
|
|
|
|
|
that integrate through the CXD56xx's SCU.
|
|
|
|
|
|
|
|
|
|
|
|
**NuttX-8.2**. Masayuki Ishikawa implemented SMP operation of the
|
|
|
|
|
|
CX56Dxx parts. Alin Jerpelea: Added support for the Altair LTE modem
|
|
|
|
|
|
support, enabled support for accelerated format converter, rotation and
|
|
|
|
|
|
so on using the CXD5602 image processing accelerator, added ISX012
|
|
|
|
|
|
camera support, added audio and board audio control implementation,
|
|
|
|
|
|
added an audio_tone_generator, added optional initialization of GNSS and
|
|
|
|
|
|
GEOFENCE at boot if the drivers are enabled, added an lcd examples
|
|
|
|
|
|
configuration.
