Thanks for the intro, Dave. NuttX has moved on a fair bit from the last time I was subscribed to the mailing list, between 2010 and 2017. Yahoo groups, anyone?
Anyhow, I’ve been adding FreeRTOS thread-awareness to Maven over the last few weeks and decided the next target would be NuttX. Dave seems to think this would be a big deal, and tried to encourage me to do something for the workshop in August, but I don’t see that happening due to time constraints. In any case, a quick intro to Maven... Maven on its native hardware has been around for a few years now, mostly as a hobby project in my retirement, but available for sale via Tindie and my website. I’ve since discontinued the original hardware as Maven firmware has outgrown the Flash/SRAM on its SoC. I do have an updated hardware design in prototype form, but this is not likely to see the light of day - I’m not a hardware guy! When I got wind of NXP’s el-cheapo MCU-Link I decided a Maven port was in order, and that it would be a free download. A few people have tried out the early versions over the last few months. At least, I think they have - I’ve had no negative feedback! There’s a NuttX-specific ReadMe file in the download describing the small additional data structure required for thread awareness. This is not set in stone; I’m happy to change it to something more akin to the OpenOCD method if that’s the consensus. This would not require you to rebuild Maven firmware (unlike with OpenOCD), as there is already support for RTOS-specific configuration parameters. In fact that’s the method used for FreeRTOS. NuttX has so many CONFIG_* options which change the sizes and offsets of the interesting data structures that it looked to be too much of a chore. Anyhow, let me know what you think.
