Using latest MCUXpresso for an LPC55S69, need to debug a possible newlib problem.
For now we'll concentrate on variant full newlib (not nano), none.
Thus a few questions for NXP:
Thanks!
Best Regards, Dave
PS: @v_canoz - This is regarding your concurrency issue...
Thanks @converse, good to know NXP did not make mods.
But I did not find any newlib debug builds on the ARM site.
Do you know where I can find debug version(s) of newlib, which is my main question?
Thanks,
Best Regards, Dave
Hi Dave,
to my knowledge there is no pre-built debug version of the library. What I did in the past (but not recently) was building it myself:
you will be better better off building it on Linux.

Hi @ErichStyger - I saw your excellent (as always) page, where I could see building newlib is a PITA. Perhaps I'll spin up a Linux VM to build it, but that always wastes a few hours too unfortunately. @v_canoz has a concurrency problem, which looks like a real platform issue (and not related to free storage). Seems really unlikely but might be GCC runtime as built for ARM or FreeRTOS. He's come up with a trivial test case that crashes despite plenty of stack space and no obvious configuration settings error. I checked all the usual suspects. More likely MCUXpresso build setting wrong somehow, but I don't see it yet.
NXP take their GNU Tools releases (unchanged) directly from the ARM GNU Tools project. Everything you need can be found there:
If you think there is a bug, search the GNU newlib forum
