Hi Bob, for low cost BSPs you can have a look at some allwinner boards from FriendlyElec and OrangePi.
I've created meta layer to support most of the H2, H3 and H5 arm cores here: https://layers.openembedded.org/layerindex/branch/master/layer/meta-allwinner-hx/ So you can grab any of those boards that has a GbE. Now, regarding the need of binary firmwares for the NICs I can't tell you which of the boards the do fill your needs, but I guess you can have a look. Some boards the support GbE are: FriendlyElec: - NanoPi-Neo2 ~20USD (http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO2 ) - NanoPi-K1 Plus ~35USD ( http://wiki.friendlyarm.com/wiki/index.php/NanoPi_K1_Plus) - NanoPi Neo Plus2 ~35USD ( http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO_Plus2) OrangePi: - Orange Pi Zero Plus ~15EUR ( https://www.aliexpress.com/store/product/Orange-Pi-Zero-Plus-H5-Chip-Quad-Core-Open-source-Cortex-A53-512MB-development-board-beyond/1553371_32828347476.html ) - Orange Pi PC2 ~20USD ( https://www.aliexpress.com/store/product/New-Orange-Pi-PC-2-H5-64bit-Support-the-Lubuntu-linux-and-android-mini-PC-Beyond/1553371_32761481418.html ) - Orange Pi Zero Plus2 ~24USD ( https://www.aliexpress.com/store/product/Orange-Pi-Zero-Plus-2-H5-Quad-core-Bluetooth-mini-PC-Beyond-Raspberry-Pi-2-Wholesale/1553371_32801249806.html ) - Orange Pi Prime ~41USD ( https://www.aliexpress.com/store/product/Orange-Pi-Prime-Development-Board-H5-Quad-core-Support-linux-and-android-Beyond-Raspberry-Pi-2/1553371_32803048527.html ) Soon (probably this weekend), I'll release a new meta layer that supports the NanoPi-Neo4 board, which has an RK3399 + GbE. If you're interested I'll send you the link for the repo. That costs ~50USD (http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO4) Now, regarding the H2, H3 and H5 I do also support RT kernels for the 4.14 and the 4.19. So these are your options: - 4.14.78 SMP - 4.19.21 SMP - 4.14.78 PREEMPT-RT - 4.19.15 PREEMPT-RT I do updates from time to time on the layer, but not that often. Hope that helps a bit.
