X-SW-Source: 2015-10/txt/msg00004.txt.bz2 Hi, my opinion is quite differently: You do not see a lot of activities in the eCos community because of politics and commercial interests. My company was very active in eCos projects (specially porting projects and development toolchain) within several years. Beside several application projects based on eCos we have made a couple of portings to different processor platforms for microcontroller vendors (Atmel, Xilinx) and OEMs. We tried to commit all this ports to the community! Specially one of the OEMs (Softing AG, Munich) was very active by himself in this commitment activity as well. But from eCos maintainer side there is no interest to overtake such ports. This is just a guess, but in my opinion the reason for this is, that the maintainers of public eCos are as well strongly commercial oriented. It seems, they will not put any port to official open source repository if it could disturb commercial interests (eCosCentric/eCosPro...). I will give just one example when we tried to make a port public: http://bugs.ecos.sourceware.org/show_bug.cgi?id=1001649 further activities, if you search for in detail: http://bugs.ecos.sourceware.org/buglist.cgi?quicksearch=at91sam9G45 beside this there was email traffic as well with the maintainers, but finally there was no success! Additionally I need to say, that you will be thwarted, if you try to offer commercial activities as well. If you are not absolutely carefully about usage of eCos name and logo, you will get some letters from eCosCentric's lawyer! In consideration of our experiences I do not wonder, that the audience is losing interest in eCos and is searching for alternatives. We have already customers, who decided against eCos specially because the fact, that there is dramatically decreasing activity in the community!
