On SA62 seco give a guideline to build an yocto 1.7 image (possible to use qt 5.3.1) that i never can be build to the end (perhaps i did something wrong) , same with ticketing ! As you can say (perhaps), Graugans , make an amazing work to create an udoo recipe for yocto 2 http://www.udoo.org/forum/threads/openembedded-yocto-on-udoo-boards.2965/ this recipe work very well with neo and quad (for the moment we just improve some modules on qt5 ...) and is it possible to build an image with qt5.5.1 and to make a sdk (tested and approved !). The quad and Sa62 as the same base (cortex M3 less) , and it would be very interesting for the people who want to use yocto to switch between all the cards (neo, quad and SA62). For that reason i asked Graugans, if it can make a try to build an image for A62 with it recipe. But unfortunately it don't work (big thanks to him for his time !), issues with kernel and uboot ! Like Graugan said me they don't use a SPL Uboot like udoo and kernel bail out because GCC is 5.0 and some patches are missing ... I didn't have all the knowledge that have Graugans to try, but perhaps we can ask Seco to adapt the kernel and uboot to have the same level than udoo. @andrea, can you ask the question at Seco please ? i think you have more contacts than us.
