Wire the RTL8721F km4tz core up to a working NuttShell: - irq.h: renumber the KM4TZ external vector table to the RTL8721F APIRQn map (UART_LOG=24, IPC=5, +GPIOB/C, TIMER7/8, ...). - ameba_loguart.c: fix the LOG-UART base to 0x40810000. The former 0x401C6000 belongs to a different Ameba part; the wrong base bus- faulted on the RX interrupt-enable write while TX still worked (LOGUART_PutChar uses its own ROM-internal base). - ameba_app_start.c: adjust the MPU read-only / RAM regions for the RTL8721F memory map and seed the RTC on first power-on so the SDM32K-clocked SYSTIMER comes up (mirrors the SDK app_rtc_init). - ameba_ipc.c: move the km4tz<->km4ns IPC to APIRQn 5 (IPC_CPU0). - ameba_board.mk: pull in fwlib ameba_rtc.c for the RTC_* symbols. - defconfig: RTL8721F RAM map, enable TIMER/TIMER_ARCH/ARMV8M_SYSTICK for a live system tick, and drop the WiFi/NET stack for now. - scripts/Make.defs: use the RTL8721F_NOR flash profile. Boots cleanly to nsh> on hardware; tick, RX and builtin apps verified. Signed-off-by: dechao_gong <dechao_gong@realsil.com.cn> |

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.
