K230 chip has two T-Head C908 RiscV cores, previously we run NuttX on either little or big cores. This patch runs NuttX on both cores with OpenAMP support via the RPTUN driver. New additions: - in arch/risc-v/src/k230 - k230_rptun.c K230 RPTUN driver - k230_rptun.h K230 RPTUN driver header file - in baords/risc-v/k230/canmv230 - configs/master Build config for master node - configs/remote Build config for remote node - scripts/ld-rptun.script Build script for RPTUN Major changes: - arch/risc-v/Kconfig Select NUTTSBI_LATE_INIT upon NUTTSBI - in arch/risc-v/include - k230/irq.h Add UART3 IRQ defs - in arch/risc-v/src/k230 - Kconfig Add RPTUN related config items - Make.defs Add k230-rptun.c to sources - hardware/k230_memorymap.h Add K230 device and CSR defs - k230_hart.c Add hart ctrl for RPTUN - k230_hart.h Add hart ctrl for RPTUN - k230_mm_init.c Add Svpmbt to support RPTUN - k230_start.c Revised to support RPMsg UART - in boards/risc-v/k230/canmv230 - scripts/Make.defs Add RPTUN script selection - src/canmv_init.c Add RPTUN and RPMsg_UART initialization - in Documentation/platforms/risc-v/k230/boards/canmv230 - index.rst Add AMP usage information.

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.
