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!

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

Apache #NuttX RTOS supports 64-bit multi-core Arm Cortex-A53 ... Let's test it on #QEMU today ... Maybe on #PinePhone someday!

This #LoRaWAN Bug on PineDio Stack #BL604 looks ... Complicated 🤔

https://github.com/apache/incubator-nuttx/pull/6803#issuecomment-1221233188

This #NuttX Commit caused LoRaWAN to fail on PineDio Stack #BL604 ... Why? 🤔

https://github.com/apache/incubator-nuttx/commit/4dbf4555ebb743a908e3016d43b5b456d7a2cf16

#ZigLang reads a Sensor on Apache #NuttX RTOS ... Thanks to "comptime" metaprogramming

https://lupyuen.github.io/articles/visual?23#appendix-read-sensor-data

Something in #NuttX broke LoRaWAN on PineDio Stack #BL604 last week ... Let's bisect last week's commits and find out why 🤔
