Pre-release

Read the article...

"Star64 JH7110 + NuttX RTOS: RISC-V PLIC Interrupts and Serial I/O"

See below for the Build Outputs. We built NuttX with these steps...

## Install the Build Prerequisites and Toolchain:
## https://lupyuen.github.io/articles/nuttx#install-prerequisites
## https://lupyuen.github.io/articles/riscv#appendix-download-toolchain-for-64-bit-risc-v

## Download the `star64d` branch of our WIP NuttX Repos
mkdir nuttx
cd nuttx
git clone --branch star64d https://github.com/lupyuen2/wip-pinephone-nuttx nuttx
git clone --branch star64d https://github.com/lupyuen2/wip-pinephone-nuttx-apps apps

## Configure and build NuttX
cd nuttx
tools/configure.sh rv-virt:knsh64
make

## Build Apps Filesystem
make export V=1
pushd ../apps
./tools/mkimport.sh -z -x ../nuttx/nuttx-export-*.tar.gz
make import V=1
popd

## Generate Initial RAM Disk
genromfs -f initrd -d ../apps/bin -V "NuttXBootVol"

## We assume that `nuttx` contains the NuttX ELF Image.
## Export the NuttX Binary Image to `nuttx.bin`
riscv64-unknown-elf-objcopy \
  -O binary \
  nuttx \
  nuttx.bin

## Dump the disassembly to nuttx.S
riscv64-unknown-elf-objdump \
  -t -S --demangle --line-numbers --wide \
  nuttx \
  >nuttx.S \
  2>&1

## Dump the init disassembly to init.S
riscv64-unknown-elf-objdump \
  -t -S --demangle --line-numbers --wide \
  ../apps/bin/init \
  >init.S \
  2>&1

## Copy the config to nuttx.config
cp .config nuttx.config

## Copy NuttX Binary Image, Device Tree and
## Initial RAM Disk to TFTP Folder
cp nuttx.bin $HOME/tftproot/Image
cp jh7110-star64-pine64.dtb $HOME/tftproot
cp initrd $HOME/tftproot

## Boot NuttX over TFTP:

WIP: Apache NuttX RTOS for Pine64 Star64 JH7110 RISC-V SBC (Kernel Mode) Pre-release

Pre-release

Read the article...

"Star64 JH7110 + NuttX RTOS: RISC-V Privilege Levels and UART Registers"

See below for the Build Outputs. We built NuttX with these steps...

## Install the Build Prerequisites and Toolchain:
## https://lupyuen.github.io/articles/nuttx#install-prerequisites
## https://lupyuen.github.io/articles/riscv#appendix-download-toolchain-for-64-bit-risc-v

## Download the `star64a` branch of our WIP NuttX Repos
mkdir nuttx
cd nuttx
git clone --branch star64a https://github.com/lupyuen2/wip-pinephone-nuttx nuttx
git clone --branch star64a https://github.com/lupyuen2/wip-pinephone-nuttx-apps apps

## Configure and build NuttX
cd nuttx
tools/configure.sh rv-virt:knsh64
make

## We assume that `nuttx` contains the NuttX ELF Image.
## Export the NuttX Binary Image to `nuttx.bin`
riscv64-unknown-elf-objcopy \
  -O binary \
  nuttx \
  nuttx.bin

## Dump the disassembly to nuttx.S
riscv64-unknown-elf-objdump \
  -t -S --demangle --line-numbers --wide \
  nuttx \
  >nuttx.S \
  2>&1

## Copy the config to nuttx.config
cp .config nuttx.config

## To boot NuttX on Star64, we prepare the Armbian MicroSD Card:
## Download the Armbian Image (Minimal) for Star64: https://www.armbian.com/star64/
## Or pick the latest Star64 Minimal Image: https://github.com/armbianro/os/releases/
## Uncompress the `.xz` file. Write the `.img` file to a microSD Card with
## Balena Etcher: https://www.balena.io/etcher/
## or GNOME Disks: https://wiki.gnome.org/Apps/Disks

## Fix the Missing Device Tree in the Armbian MicroSD Card:
sudo chmod go+w /run/media/$USER/armbi_root/boot
sudo chmod go+w /run/media/$USER/armbi_root/boot/dtb/starfive
cp \
  /run/media/$USER/armbi_root/boot/dtb/starfive/jh7110-visionfive-v2.dtb \
  /run/media/$USER/armbi_root/boot/dtb/starfive/jh7110-star64-pine64.dtb

## Delete Linux Kernel `/boot/Image`
rm /run/media/$USER/armbi_root/boot/Image

## Copy `nuttx.bin` to Linux Kernel `/boot/Image`
cp nuttx.bin /run/media/$USER/armbi_root/boot/Image

## Insert the MicroSD Card into Star64 and power up.
## Or try Network Booting with TFTP (instead of MicroSD):
## https://lupyuen.github.io/articles/tftp

WIP: Apache NuttX RTOS for Pine64 Star64 JH7110 RISC-V SBC Pre-release

Pre-release

Read the article...

"Apache NuttX RTOS on RISC-V: Star64 JH7110 SBC"

See below for the Build Outputs. We built NuttX with these steps...

## Install the Build Prerequisites and Toolchain:
## https://lupyuen.github.io/articles/nuttx#install-prerequisites
## https://lupyuen.github.io/articles/riscv#appendix-download-toolchain-for-64-bit-risc-v

## Download the `star64` branch of our WIP NuttX Repos
mkdir nuttx
cd nuttx
git clone --branch star64 https://github.com/lupyuen2/wip-pinephone-nuttx nuttx
git clone --branch star64 https://github.com/lupyuen2/wip-pinephone-nuttx-apps apps

## Configure and build NuttX
cd nuttx
tools/configure.sh rv-virt:knsh64
make menuconfig
## In Build Setup > Debug Options,
## Enable Warnings Output, Info Debug Output, Debug Assertions Show Expression
## Save and exit menuconfig
make

## We assume that `nuttx` contains the NuttX ELF Image.
## Export the NuttX Binary Image to `nuttx.bin`
riscv64-unknown-elf-objcopy \
  -O binary \
  nuttx \
  nuttx.bin

## Dump the disassembly to nuttx.S
riscv64-unknown-elf-objdump \
  -t -S --demangle --line-numbers --wide \
  nuttx \
  >nuttx.S \
  2>&1

## Copy the config to nuttx.config
cp .config nuttx.config

## To boot NuttX on Star64, we prepare the Armbian MicroSD Card:
## Download the Armbian Image (Minimal) for Star64: https://www.armbian.com/star64/
## Or pick the latest Star64 Minimal Image: https://github.com/armbianro/os/releases/
## Uncompress the `.xz` file. Write the `.img` file to a microSD Card with
## Balena Etcher: https://www.balena.io/etcher/
## or GNOME Disks: https://wiki.gnome.org/Apps/Disks

## Fix the Missing Device Tree in the Armbian MicroSD Card:
sudo chmod go+w /run/media/$USER/armbi_root/boot
sudo chmod go+w /run/media/$USER/armbi_root/boot/dtb/starfive
cp \
  /run/media/$USER/armbi_root/boot/dtb/starfive/jh7110-visionfive-v2.dtb \
  /run/media/$USER/armbi_root/boot/dtb/starfive/jh7110-star64-pine64.dtb

## Delete Linux Kernel `/boot/Image`
rm /run/media/$USER/armbi_root/boot/Image

## Copy `nuttx.bin` to Linux Kernel `/boot/Image`
cp nuttx.bin /run/media/$USER/armbi_root/boot/Image

## Insert the MicroSD Card into Star64 and power up.
## Or try Network Booting with TFTP (instead of MicroSD):
## https://lupyuen.github.io/articles/tftp

We use rv-virt:knsh64 (NuttX Kernel Mode) instead of rv-virt:nsh64 (NuttX Flat Mode) so that NuttX will run in RISC-V Supervisor Mode. (Instead of RISC-V Machine Mode)

Here's the Star64 Output Log...
