Run the test on sim with CONFIG_SIM_ASAN and CONFIG_SIM_UBSAN 2. Run the test on real device with CONFIG_MM_KASAN, CONFIG_MM_UBSAN and CONFIG_STACK_CANARIES and fix the possible errors reported by these tools. > Have you tried to run these tests? > Do they succeed? > > > On Wed, Aug 24, 2022 at 4:23 AM Mike Mogenson > wrote: > > > Hello, > > > > I’ve published two articles about using Lua on NuttX with libuv for > > asynchronous IO and networking: > > > > https://medium.com/@michael.mogenson/using-lua-on-nuttx-bcc9a39b2814 > > > > > > > https://medium.com/@michael.mogenson/using-lua-and-libuv-for-async-networking-on-nuttx-6e4635eeaedc >

Re: Lua on NuttX blog posts
Hello Mike! I have also been using Lua on microcontrollers for many years, with great success. For The last couple of years I have been running Lua on NuttX, these two are great when combined! Quite recently I tried running the Lua tests suite (http://www.lua.org/tests) on NuttX, and to my surprise, I got multiple failures. Some of them are related to issue #6941, but I also got more. I even get corruption of the heap in some cases. Have you tried to run these tests? Do they succeed?

Article: PinePhone boots NuttX
NuttX now boots on Pine64's PinePhone! (Arm Cortex-A53) This article explains the changes that I made... https://lupyuen.github.io/articles/uboot Lup
Re: Article: NuttX on Arm Cortex-A53 and PinePhone
Thank you so much Nathan! Yes it would be super interesting to see NuttX on Pi, I hope to run it someday :-) Lup On Fri, Aug 26, 2022 at 7:51 AM Nathan Hartman wrote: > On Wed, Aug 24, 2022 at 8:05 PM Lee, Lup Yuen wrote: > > > > NuttX now supports 64-bit Arm Cortex-A53 with Multi-Core SMP...
