WIP: Apache NuttX RTOS for RISC-V QEMU (Initial RAM Disk)
Read the article...
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 `ramdisk` branch of our WIP NuttX Repos
mkdir nuttx
cd nuttx
git clone --branch ramdisk https://github.com/lupyuen2/wip-pinephone-nuttx nuttx
git clone --branch ramdisk https://github.com/lupyuen2/wip-pinephone-nuttx-apps apps
