On K3 SoCs the A53 cluster does not own device power, clocks, resets or interrupt routing; these are managed by the DM/TIFS firmware and requested over TISCI through the secure-proxy mailbox. Add: - a TISCI client (secure-proxy transport plus device/clock/reset helpers) - a GPIO driver for banks 0/1 with pad mux and TISCI power-on - an OMAP-I2C driver for the main-domain I2C controllers and wire them into the PocketBeagle2 and BeaglePlay bring-up. Tested on PocketBeagle2 (SYSFW 11.2.5) with the TechLab cape attached: nsh> i2c bus nsh> i2c dev -b 0 0x03 0x77 # I2C0 detects onboard 0x20 and 0x50 nsh> gpio -o 1 /dev/gpio3 # drives a user LED; read back with: nsh> gpio /dev/gpio3 Signed-off-by: Piyush Patle <piyushpatle228@gmail.com> |

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.
Contributing
If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
