Hello Nathan Firstly I am really grateful for your long suggestions. I am very surprised to spend so much time writing this for me.
Secondly, I already tried building GNU Radio natively in Odroid xu3 and Hummingboard. They both took long time to build. And I always meet some bugs, but I fixed them. Building GNU Radio on Hummingboard is definitely a pain. I want to concentrate on cross compile now even I have native compile option. I am reading Open Embedded website now, OE layer does not support Odroid XU3 layer. 1>What do you mean for "add support"? 2>I am going to try Tom's rootfs and chroot once I understand it. 3> Is this the website you are talking about for cross compile with OE https://github.com/balister/meta-sdr/wiki/CrossCompile. the first three steps are 1)Build the cross toolchain with OpenEmbedded: bitbake -c populate_sdk gnuradio-dev-image 2)Find the sdk: $ ls tmp-eglibc/deploy/sdk/ oecore-x86_64-armv7a-vfp-neon-toolchain-nodistro.0.sh 3)Install the sdk: '$ sudo sh tmp-eglibc/deploy/sdk/oecore-x86_64-armv7a-vfp-neon-toolchain-nodistro.0.sh` But the problem is that this SDK file is for Zynq chip. http://gnuradio.org/data/sdk/zedboard_armv7a-sf-vfp-neon/ Do you have any idea how to build SDK for ARMV7L which is used in Odroid xu3? According to my understand of reading in GNURadio website, it seems the number 3) way is the same way as get an SDK for my distribution. I read from this website https://gnuradio.org/redmine/projects/gnuradio/wiki/OE_PyBOMBS >From what you said, it seems I can either combine OE and SDK to do cross compile or JUST use SDK for my distribution. I have not found any resource for the later option. Since you said the later option is unknown and hard, I will save this for later. I am going to try the Tom's rootfs way and OE SDK way firstly, I will keep posting my questions, thank you so much for your time and help. I am super grateful!
