	* When trying to build armadeus-7.0 on Ubuntu 18.04, you will encounter a lot of small compilation issues, that can be adressed manually, but we highly recommend to use more recent armadeus BSP versions on Ubuntu 18.04 to avoid these problems.

	* 4.17 kernel seems to have some problems when using CPU frequency scaling and/or i.MX6ULL at full speed (900MHz). Consequences are random kernel crashes with stack overflow/memory problems. For these reasons we recommend everyone using this kernel/release and i.MX6ULL to add a patch in ''patches/linux/4.17/''.		* Due to NXP specifications changes, 4.17 kernel seems to have some problems when using CPU frequency scaling and/or i.MX6ULL at full speed (900MHz). Consequences are random kernel crashes with stack overflow/memory problems. For these reasons we recommend everyone using this kernel/release and i.MX6ULL to add a patch in ''patches/linux/4.17/''.

			* Then we also recommend to de-activate CPU frequency scaling on i.MX6ULL and fix operating frequency (to put somewhere in your app starting script, here frequency is fixed to 900MHz):
