@sg- @0xc0170 Please review

@SeppoTakalo I only see a M3 build. I thought there was going to be a M0 build as well.

[SeppoTakalo]

@sg- Now Cortex-M0, M0+, M3 and M4 libraries are there.

I did not create symlinks, because I don't know if those work on Windows.

@SeppoTakalo Its failing to respond to ping with mesh-minimal example. Can you check this?

Hi @SeppoTakalo, I know this is a change, but would it be possible to move FEATURE_IPV6 into features/net to match the organization of network related features? features/net/FEATURE_IPV6

related prs #2231, #2216

@SeppoTakalo, I tried out the m3/m4 and I can get thread to work, but not 6lowpan. It looks like 6lowpan didn't get fully compiled in. I also tried using the m0/m0+ library on a K64F (since the m3/m4 library was broken) but I get link errors like this:

libnanostack_arm-none-eabi-gcc_Cortex-M0.a(security_lib.o): In function `sec_ecc_state_free':
security_lib.c:(.text+0xec): undefined reference to `ecc_free_memory'

[SeppoTakalo]

Verified: GCC modules (at least) are broken. I think I have accidentally build them with some other than mbedOS configuration of stack.
I will do rebasing and updating immediately.
I will also study how to build the Cortex-A modules (in progress).

Thanks for reporting and testing this. Sorry for the trouble.

[SeppoTakalo]

Wait.. why did Github closed this.. maybe because I updated my branch...

[SeppoTakalo]

OK. Now libraries updated.
6LoWPAN seems to work.
Thread tests pending... waiting for BR build.

[SeppoTakalo]

Also added Cortex-A libraries.

[SeppoTakalo]

Verified with these binaries:
mesh-minimal with 6LoWPAN: works
mesh-minimal with Thread: works
K64F border router with 6LoWPAN: works
K64F border router with Thread: works. (not public)

Problems with thread were in application side configuration on border router. PR's submitted to Thread testapps.

Thanks for moving this last minute 👍
