Hi Bob,
for low cost BSPs you can have a look at some allwinner boards from
FriendlyElec and OrangePi.
That's excellent. Thank you. Do any of these boards have accessible
JTAG for debugging the kernel? Is this something you have done in
supporting the BSPs? I see a UART port is listed as a debug port. Is
the idea to use KGDB via this port?
Bob
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.

Hello All,
Can anyone recommend a ~$50 dev board that runs Yocto and has a
single
Gigabit Ethernet port?
The boards we are aware of either have 100Mbit Ethernet, don't
meet the
price target, or has a Gigabit Ethernet port that has reduced
capabilities via firmware (Ethernet driver isn't open source).
Thank you,
Bob
