Seconded. However, this is all not true if you care about industrial projects and their quality requirements; you need chips with long term availability there, with reliable operation at the specified frequency for > 10 years and without problematic manufacturing processes like required by POP. But in general yes - the number of applications which really require a uCLinux device is going down. > Ergo, the days of projects like Linux-tiny are behind us. There is one exception: if you care about energy efficiancy. The cortex m3 port we are currently moving forward, for EFM32, is for a device which runs 10 years on a cab size battery. This is still not possible with the "big" arm devices. 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 | _______________________________________________ Celinux-dev mailing list Celinux-dev@lists.celinuxforum.org https://lists.celinuxforum.org/mailman/listinfo/celinux-dev
