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 ---

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 ---

I think its also included in the official Cortex-M GCC distributed from [Launchpad.com](http://Launchpad.com). ---

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 ---

Check my recent posts to the newlib list for some context.
