FreeRTOS + newlibPosted by Chris Morgan on June 2, 2013 Wanted to bring this thread up again, http://sourceware.org/ml/newlib/2008/msg00384.html, because I spent several hours debugging the issue. Even though I'm pretty well versed in this stuff it took a lot of effort to get to the root cause. Any interest in me submitting patches for this support, along with a configuration setting for newlib and maybe some documentation? Chris RE: FreeRTOS + newlibPosted by Richard on June 2, 2013 Please add a link to the same post in the SourceForge feature request tracker. [Personally I try and avoid using Newlib at all cost as it is, in my humble opinion, not suited to the majority of microcontroller work. If you are using ARM architectures then ARM provide a micro lib for GCC now, which is always going to be preferable. However, as FreeRTOS gets used on larger and larger processors adding this functionality becomes more appropriate] Regards. RE: FreeRTOS + newlibPosted by Chris Morgan on June 2, 2013 Hi Richard. Which micro lib are you referring to for gcc on arm? I'm using an stm32f1 part. I wasn't aware that there was one. Presuming I go the newlib route, should I just submit the patches to the patch tracker here on sourceforge? Chris RE: FreeRTOS + newlibPosted by Dave on June 2, 2013 Google newlib-nano and you will find something. I think its also included in the official Cortex-M GCC distributed from Launchpad.com. RE: FreeRTOS + newlibPosted by Chris Morgan on June 2, 2013 Hi Dave. It looks like Bin Cheng is submitting the patches to newlib mainline. I'm not sure how easy it would be for me to pull in newlib-nano but maybe I'll look at it at some point. Given that newlib is pulling in the changes from newlib-nano maybe it makes more sense for FreeRTOS to have support for newlib? Chris RE: FreeRTOS + newlibPosted by Richard on June 2, 2013 Please post the same link you have already posted here to the feature request tracker, rather than posting a patch. Thanks and regards. RE: FreeRTOS + newlibPosted by Chris Morgan on June 2, 2013 Hi Richard. Added to the feature request tracker. Chris RE: FreeRTOS + newlibPosted by Carl Norum on June 6, 2013 I'm using newlib-nano (with some local patches to fix up thread safety in stdio). Note that newlib-nano has broken malloc locking, so you'll want to fix that too, probably. Check my recent posts to the newlib list for some context.
