#LoRaWAN Join Accept Response is returned in 5 to 6 seconds from Join Request ... Jotting a note to remind myself 🙄

Beachy Friday ☀️

After patching the Floating-Point ABI, our #ZigLang App runs on #BL602 with Apache #NuttX RTOS! 🎉

https://github.com/lupyuen/zig-bl602-nuttx#zig-runs-ok

We do ELF Header Surgery on the #ZigLang Output for #BL602 ... And change "Software Floating-Point ABI" to "Hardware Floating-Point ABI"

https://github.com/lupyuen/zig-bl602-nuttx#patch-elf-header

But #ZigLang Compiler produces an Object File with Software Floating-Point ABI ... This won't link with #BL602 #NuttX on Hardware Floating-Point!

https://github.com/lupyuen/zig-bl602-nuttx#floating-point-abi

Apache #NuttX RTOS was compiled for #BL602 with Hardware Floating-Point ABI: "gcc -march=rv32imafc -mabi=ilp32f"

https://github.com/lupyuen/zig-bl602-nuttx#floating-point-abi

Apache #NuttX RTOS fails to link with our #ZigLang Compiled App ... Let's find out why we "can't link soft-float modules with single-float modules"

https://github.com/lupyuen/zig-bl602-nuttx#floating-point-abi

#ZigLang Target CPU for #RISCV #BL602 is "sifive_e76" ... Because it matches RV32IMACF

https://github.com/lupyuen/zig-bl602-nuttx#zig-target

Here's how we compile our #ZigLang App for #RISCV #BL602

https://github.com/lupyuen/zig-bl602-nuttx#compile-zig-app

Apache #NuttX RTOS fails to build our #ZigLang App ... But no worries! Let's compile it ourselves

https://github.com/lupyuen/zig-bl602-nuttx#build-fails-on-nuttx

We enable the #ZigLang Demo App via "menuconfig" on Apache #NuttX RTOS

https://github.com/lupyuen/zig-bl602-nuttx#enable-zig-app

Apache #NuttX RTOS is bundled with a simple #ZigLang App ... Let's run this on #BL602

https://github.com/lupyuen/zig-bl602-nuttx#zig-app-for-nuttx

Will #ZigLang run on #RISCV #BL602 ... With Apache #NuttX RTOS? Let's find out!

https://github.com/lupyuen/zig-bl602-nuttx

Apache #NuttX RTOS is a great platform for creating Drivers and Apps for #PineDio Stack #BL604

https://lupyuen.github.io/articles/auto2?25#why-nuttx

Reconciling updates between #NuttX Mainline, PineCone #BL602 and PineDio Stack #BL604 ... Very carefully

https://lupyuen.github.io/articles/auto2?23#merge-conflicts

Apache #NuttX Updates for PineDio Stack #BL604 shall be merged back into PineCone #BL602 ... So everything everywhere gets in sync

https://lupyuen.github.io/articles/auto2?22#pinedio-stack-to-pinecone

Here's how we merge updates from #NuttX Mainline into PineCone #BL602 and PineDio Stack #BL604

https://lupyuen.github.io/articles/auto2?21#pinecone-to-pinedio-stack

Does "Alongside" bother anyone? 🤔

Syncing Apache #NuttX RTOS with #PineDio Stack #BL604 and PineCone BL602 ... Looks complicated but I'll explain everything

https://lupyuen.github.io/articles/auto2?20#merge-updates-from-nuttx

We pull updates from #NuttX Mainline and test them on #PineDio Stack #BL604 every 2 weeks
