#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)

`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)

The PineNote is here! I'm planning on making a hands on video to share my experience. Let me know if you have any questions you want me to try and answer. I don't plan to do technical tests but open to collaborating on it.
First impression, feels like a quality and sturdy device. Feels good in the hand, the texture is a kinda soft grippy plastic. Pen felt good, the writing friction seems ok, I don't want to make any software qualifications until I update the device but still happy with the out-of-box experience. The wake from sleep time is essentially instant.
@PINE64 great work on the PineNote, I'm very impressed with the hardware!
Edit: Link to blog post with thoughts after day one. Since I'm on a single user instance most people may not see the thread with info that hasn't been boosted, the post has all of it.
