# Summary This PR adds support for PINE64 PinePhone and the Allwinner A64 SoC (based on Arm Cortex-A53). With this PR, PinePhone boots successfully to nsh (via microSD Card) and runs console apps. ## Changes to Kconfig - `arch/arm64/Kconfig`: Added Allwinner A64 SoC - `boards/Kconfig`: Added PINE64 PinePhone - `arch/arm64/src/a64/Kconfig`: New Kconfig for Allwinner A64 SoC - `boards/arm64/a64/pinephone/Kconfig`: New Kconfig for PINE64 PinePhone ## Additions to arch/arm64 - `src/a64/a64_boot.c`, `a64_boot.h`: Boot functions for Allwinner A64 - `src/a64/a64_lowputc.S`: Low-level console output - `src/a64/a64_serial.c`, `a64_serial.h`: A64 Serial Driver - `src/a64/chip.h`: A64 SoC Definitions - `include/a64/chip.h`: A64 Memory Map, Generic Interrupt Controller - `include/a64/irq.h`: A64 Interrupts - `src/a64/Make.defs`: Source files for A64 ## Additions to boards/arm64/a64/pinephone - `configs/nsh/defconfig`: Board Configuration for `pinephone:nsh` - `src/pinephone_appinit.c`: Init PinePhone - `src/pinephone_boardinit.c`: Init PinePhone - `src/pinephone_bringup.c`: Start PinePhone Drivers - `src/pinephone.h`: PinePhone Declarations - `include/board_memorymap.h`: PinePhone Memory Map - `scripts/dramboot.ld`: PinePhone Linker Script - `scripts/Make.defs`: Source files for PinePhone - `src/Makefile`: PinePhone Makefile ## Changes to Documentation - `platforms/arm/a64/boards/pinephone/index.rst`: Building and booting NuttX on PinePhone - `platforms/arm/a64/index.rst`: Overview of Allwinner A64 - `introduction/supported_platforms.rst`: Added Allwinner A64 - `introduction/detailed_support.rst`: Added Allwinner A64 # Impact With this PR, PinePhone boots successfully to nsh (via microSD Card) and runs console apps. We select PinePhone through the new Board Configuration `pinephone:nsh`: ```bash ./tools/configure.sh -l pinephone:nsh ``` There is no impact on the existing implementation of QEMU for Armv8-A (`qemu-armv8a`). # Testing We tested by booting PinePhone with a microSD Card that contains NuttX: ```bash ## Configure and build NuttX ./tools/configure.sh -l pinephone:nsh make ## Compress the NuttX Image cp nuttx.bin Image rm -f Image.gz gzip Image ## Copy to PinePhone Jumpdrive microSD Card ## https://lupyuen.github.io/articles/uboot#pinephone-jumpdrive cp Image.gz "/Volumes/NO NAME" ``` When we insert the microSD Card into PinePhone and power it up, PinePhone boots successfully to nsh and runs console apps: - [NuttX PinePhone Log](https://gist.github.com/lupyuen/e49a22a9e39b7c024b984bea40377712) Two lines of messages appear garbled because two tasks were printing messages simultaneously: _"nsh: sysinit: fopen failed: 2"_ and _"nsh: mkfatfs: command not found"_ This will be fixed in a later PR. -- This is an automated message from the Apache Git Service.
