Finding the Generic Interrupt Controller on #PinePhone

https://lupyuen.github.io/articles/interrupt?3#allwinner-a64-gic

Generic Interrupt Controller in #PinePhone is particularly problematic ... It was created 11 years ago for 32-bit Arm CPUs!

Microsoft Visual C++ ... Runtime Error!

#PinePhone Interrupts are complicated ... That's why we need a Generic Interrupt Controller to handle them

How does #PinePhone handle Arm64 Interrupts? Let's find out ... With a little help from Apache #NuttX RTOS

#NuttX Shell now runs OK on #PinePhone @PINE64 ! 🎉

Plenty to be done for #NuttX RTOS on #PinePhone ... Lemme know if you'd like to join me! 🙏

Here's how we build #NuttX RTOS for #PinePhone

https://lupyuen.github.io/articles/uboot?18#appendix-build-nuttx-for-pinephone

#NuttX RTOS has plenty of Arm64 Code that will be helpful to creators of #PinePhone Operating Systems

#NuttX RTOS on #PinePhone isn't fully working yet ... Here are the upcoming fixes

Here's how we make a #Linux Kernel Header ... For our non-Linux #PinePhone OS

#PinePhone's U-Boot Bootloader expects a #Linux Kernel Header ... Let's make one ourselves
