addendum to unified kernel RFC: getting rid of MDEF files.
Benjamin Walsh <benjamin.walsh@...>
Hi all,
Small addendum to the unified kernel RFC: we'd like to take out the support for MDEF files, and thus sysgen in the unified kernel. It will be kept for legacy reasons until the legacy veneer is removed. Any objections ? Cheers, Ben -- Benjamin Walsh, SMTS Wind River Rocket www.windriver.com Zephyr kernel maintainer www.zephyrproject.org

Re: Porting to Cortex-M0+
Piotr Mienkowski <Piotr.Mienkowski@...>
Hi,
I have the same problem. I would like to add support for Atmel SAM E70 chip (Cortex-M7) and was thinking that using the header files provided by Atmel as part of their ASF would make the job much, much easier. Euan, did you already add files to ext/hal/ folder? Have you talked to Maureen Helm, the ARM architecture maintainer? Should we agree on folder structure so support for future Atmel chips can be easily added? My thoughts: I think we should only add header files that define register access and do not add any device drivers. While header files are valuable the Atmel implementation of device drivers looks low quality, at least the SAM E70 package. The way API is written is not directly useful for any serious development, neither it follows CMSIS standard. While some drivers look good, some are incomplete and some are buggy. We would need to fix them and cooperate with Atmel to push changes upstream. I reckon using third party source code which is not maintained in open source model is not a viable long term solution. Not mentioning the fact that device drivers will have to be tightly integrated with Zephyr kernel. I believe it's easier to write our own drivers from scratch. Anyway, that's only my opinion. The text of SAM Software Package License included in the source code (and header files) looks actually very permissive but IANAL, also the ext/hal/ folder has already a selection of proprietary code with similar licenses. In any case we should probably get an official green light from someone. Cheers, Piotr

Moving outdir contents to a BOARD-specific subdirectory
Andy Ross
I just pushed the following to gerrit, for possible merge sometime in
the 1.6 timeframe. It will modify outdir to contain separate subdirectories for each BOARD variant built, so they won't collide in undetectable ways at build time when you swap targets or forget the make variable: https://gerrit.zephyrproject.org/r/#/c/4310/ It also will change the location of the output files for anyone building without a custom O= variable, which will impact scripting. (Though to be fair: if you're automating builds you probably want to be setting O manually!) Please be aware, and review the change if interested. Andy

Re: having trouble getting the echo client to work using TCP/uIP on K64F
Rohit Grover
Hello Community,
toggle quoted messageShow quoted text
In my attempts to get a TCP stream to flow in and out of a K64F, I've had to make a few changes to core of the uIP port: https://gerrit.zephyrproject.org/r/#/q/rohit+grover+status:open. I now have some success in getting data to flow continuously, nevertheless I haven't fixed all issues and I'm not sure my changes take all possible cases into account. These changes have had to do with errors in how uIP handles outbound packets. I'm not an expert in IP stacks, and in one particular case, https://gerrit.zephyrproject.org/r/#/c/4225/, I've not been able to provide a fix--my patch simply raises a certain retry-limit and results in the expected behaviour. I would appreciate assistance from people who may have authored the port of uIP to Zephyr. It seems to me that these issues should have surfaced for any application attempting to setup a TCP/IPv4 stream over uIP; it is a surprise that these have gone undetected so far. Rohit.

I don't see a problem with replacing the existing definition in the minimal libc with the corrected version above. Can you send a patch against lib/libc/minimal/include/stddef.h? Andrew

Naming both a top-level directory and a branch "net" is a bit unfortunate
Paul Sokolovsky
Hello,
Today I tried to figure why I got my Zephyr repository clone in an inconsistent state, and here's what I found: Git for quite a few years allow to checkout a remote's repository with: git checkout <short-remote-name> e.g. git checkout net is supposed to just checkout origin/net if didn't have it already, and set it up a tracking remote branch. Well, that doesn't work with Zephyr, because there's "net" top-level directory. It's easy to overlook that "git checkout net" didn't produce a notice of switching to another branch/setting up tracking, and wonder why you didn't have the latest net's commits in git log. My next step was to pull these branch changes explicitly: "git pull --rebase origin net", and that's how I ended up with net's commit in my master branch. I hope it's just me, but posting this in case someone else will have a similar problem (or if maintainers get similar hard-to-explain reports of "my local repo got messed up!"). The solution is to use explit --track option: git checkout -b net --track origin/net (I didn't have to use --track explicitly for a couple of years). -- Best Regards, Paul Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

Reliability of Gerrit/Jira server
Paul Sokolovsky
Hello,
I more or less regularly (e.g., once a day) get following when pull from the Zephyr repo: $ git pull --rebase fatal: unable to access 'https://gerrit.zephyrproject.org/r/zephyr/': GnuTLS recv error (-9): A TLS packet with unexpected length was received. Also, sometimes, it takes quite a while to open a particular ticket in Jira. That's not too serious though, so I'm mostly posting to help maintainers track (perceived) reliability of the project infrastructure over time. -- Best Regards, Paul Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog

offsetof() in array sizes
Carles Cufi
Hi there,
If one includes a offsetof() statement inside a macro that is then used to size an array, the following warning is issued by GCC: warning: variably modified <VAR_NAME> at file scope The fix for this, at least for GCC, is to use: #if defined(__GNUC__) #define offsetof(s, m) __builtin_offsetof(s, m) #else #define offsetof(s, m) ((size_t)(&(((s *)0)->m))) #endif Any thoughts about this particular matter? We'd like to use offsetof() when sizing arrays in the BLE Controller but we don't want to duplicate the offsetof() macro. Thanks, Carles
