Yes, this is also enough for testing it on several arm platforms. >> >>> Any advice on how to get to an x86 image without creating a new BSP from >>> scratch is appreciated.

This is good for develop your BSP/Userspace Softwate/ETC. If it's at some point that you want the 1:1 behaviour on your atom board -> flash the image and make a release after some testing. > So your advice would be to take the DistroKit BSP and create a new > platform for my x86 target? > I would suggest to copy v7a platform to a atom2510 platform. Then select this platform and start ptxdist platformconfig -> change everything to your atom platform. Then start ptxdist kernelconfig -> change everything to your platform. Then look into run-nfs/run script and qemu-common source file and change everything that it emulates a atom. --- For the switch between QEMU and your atom board, I would disable then everything what you don't need in the kernelconfig which was necessary only for doing QEMU testing stuff. btw: qemu-i386 -cpu "?" gives you a list of possible cpu emulations, there is also some: x86 n270 Intel(R) Atom(TM) CPU N270 @ 1.60GHz don't know if this fits into your use-case. For the specific platform changes -> I can't help you there. But I think there exists now a DistroKit Mailinglist [0], you can send-patches there and we will review. - Alex [0] http://www.pengutronix.de/mailinglists/index_en.html _______________________________________________ ptxdist mailing list ptxdist@pengutronix.de
