Here's how we ported Apache #NuttX RTOS to Yuzuki #Avaota-A1 SBC @PINE64 … Completed within 24 Hours! (#Allwinner A527)

https://lupyuen.org/articles/avaota.html

#NuttX Test Bot will test all #Arm64 Pull Requests on a Real #PinePhone ... Let's automate this with an #SDWire MicroSD Multiplexer and #Avaota-A1 SBC

https://lupyuen.org/articles/testbot3.html

#StarPro64 EIC7700X is the Hot New #RISCV SBC by @PINE64 ... Let's boot Linux and Apache #NuttX RTOS ... Maybe run #LLM on NPU on NuttX? (Large Language Model + Neural Processing Unit)

https://lupyuen.org/articles/starpro64.html

`uname` on Apache #NuttX RTOS became unusually quieter: Commit Hash is Missing! Watch as we stomp the seemingly simple bug ... That turns out to be something seriously sinister! (Spoiler: Static Vars are broken)

https://lupyuen.org/articles/uname.html

Our Build Farm for Apache #NuttX RTOS runs all day, all night. Continuously compiling 1,000 NuttX Targets ... Can we be 100% sure that NuttX is OK? Without getting spammed by Alert Emails? Let's turn #Mastodon into a fun new way to broadcast NuttX Alerts
