D*mn... [Maybe this explains Robert's reluctance?] Wolfgang, you know me long enough to realize that this argument is *crap*. Talking about business cases, it has turned out to be extremely difficult to explain customers that the effort for the actual functionality is only a little percentage of the work necessary to do the oftree stuff right. The functionality has often worked after a few hours, and until all oftrees have been solved, it often takes weeks. In result, this has already led to customers concluding that - mainline is not worth the effort - linux is overkill and one should better use cortex-bare-metal However, that is only our personal observation. rsc -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |
