Daily Automated Testing for #MilkV Duo S #RISCV SBC (#IKEA TRETAKT / Apache #NuttX RTOS)
Переглядів 147Місяць тому
Last week we upstreamed Milk-V Duo S SBC to Apache NuttX RTOS. (Based on Sophgo SG2000 RISC-V SoC) But NuttX Mainline changes every day. Will Milk-V Duo S suffer “Software Bit Rot”? And fail to boot NuttX someday? Let’s do Daily Automated Testing for NuttX on a Milk-V Duo S. Yep on the Actual Physical SBC! Details: lupyuen.codeberg.page/articles/sg2000a.html

What about making NuttX computer based on the same principle? Capable of many months running on the battery, or even eternally using solar panel? :)

    Hi there, I am Faruk, an SEO expert. I recently visited your UA-cam channel and wondered. Your video was fantastic! The content truly deserves more engagement and visibility, but it seems that your videos are currently struggling to gain subscribers and views! Upon review, I noticed that your channel and videos lack optimization, particularly in terms of SEO. Its current SEO score is 0 out of 100! which is lower than standard, hampering its exposure to a broader audience. Want to explore how enhancing your channel's SEO can boost your reach?

    • @lupyuenlee3400
      @lupyuenlee3400 Рік тому

      Thanks! NuttX on PinePhone is still incomplete (many drivers are missing) so maybe it's too early to compare it with Linux? But for now NuttX seems more suitable for Education, because we've documented everything that happens inside each NuttX Driver. More about this: lupyuen.github.io/articles/what

    Very cool. I'm looking forward progress on this, I'd like to use or build a "feature-phone"-style UI for the PinePhone someday. Is there USB support(In NuttX, and your port)? I think that would be the first step in getting the modem to work.

    Very awesome. I think the PinePhone is very interesting, and I'd love see a NuttX-based "feature-phone OS" for the PinePhone one day! I've been following your blog posts, and I've even used them as a sort of reference to the low-level PinePhone hardware.
