	[[~~Category: kernel~~]]		By default, the stable kernel version generated by the armadeus BSP for APF27 is 2.6.29.6. Migration toward mainline/vanilla kernel [[Kernel-upstream-status \| is in progress]] but not finished.

	~~By default, the kernel for APF27 is the 2.6.29.6. Migration for the kernel upstream [[Kernel-upstream-status \| is in progress]] but not finished, and~~ some features like [[Can \| CAN]] or [[GPIOlib]] interrupts management are not available under ~~kernel~~ 2.6.29. This ~~article~~ explain how to use a recent kernel with latest armadeus ~~trunk~~ on APF27.		However some features like [[Can \| CAN]] or [[GPIOlib]] interrupts management are not available under this 2.6.29 version. This page will explain how to build and use a recent kernel with latest armadeus BSP on APF27, for people wanting more features than 2.6.29 can offer.

	With recent ~~kernel~~ it is ~~also~~ important to know how to use kernel [[device tree]]		With recent kernels it is very important to know how to use kernel [[device tree]] mechanism !
