CC3200 build environment

Postby Niallp » Wed Feb 15, 2017 6:21 am

After reviewing the readme, I should be able to build firmware for the WiPy1 and CC3200 Launchpad using the toolchain from gcc-arm-embedded and it certainly seems to work most of the way ... builds complete with no errors and the board is mostly functional.

I can't get the builtin FTP server working properly in any local build (it just hangs after username input) yet the binaries available from micropython/download seem OK. I've tried both a WiPy1 and Launchpad, using my default workstation (Ubuntu 16.04 x64 with toolchain via PPA) as well as another clean install of gcc-arm-embedded from the latest distribution tarball on a Debian Jessie system. Results are consistently working telnet and REPL but crashing FTP.

Could anyone with a working build environment please let me know your system details (distro and version, also output of arm-none-eabi-gcc -v) ? Thanks.

Bingo, problem found ... you are using a considerably older gcc version (4.8.4) compared to what I have (6.2.1).

When I revert to gcc 4.8.4, ftp works, while the same tree built with 6.2.1 doesn't. I'll try to track down where the breakage starts then dig deeper, could be a compiler bug or a latent bug in micropython triggered by the newer versions.

Thanks !

Edit: Turns out the breakage is from 5_4-2016q2 to 5_4-2016q3, (ARM/embedded-5-branch revision 237715 and 240496 respectively) ... if anyone wants to avoid this problem, use older toolchains for now.
