Watch Apache #NuttX RTOS fire up 4 Cores of Arm Cortex-A53 ... Emulated with #QEMU

https://github.com/lupyuen/pinephone-nuttx#test-nuttx-with-qemu-multi-core

From Single Core to Multi Core ... Now we build Apache #NuttX RTOS for Arm Cortex-A53 with 4 Cores

Here's how we build Apache #NuttX RTOS for Arm Cortex-A53

https://github.com/lupyuen/pinephone-nuttx#build-nuttx-single-core

We'll cross-compile Apache #NuttX RTOS for Arm Cortex-A53 with the Arm64 Toolchain

Source: https://github.com/lupyuen/pinephone-nuttx#download-toolchain

Let's download #NuttX Mainline ... Which has the latest updates for Arm Cortex-A53

https://github.com/lupyuen/pinephone-nuttx#download-nuttx

What do #PinePhone and Apache #NuttX RTOS have in common? They both run on Arm Cortex-A53 with 4 Cores!
