Thanks for that Gerhard,
Speaking of u-boot , I had sent an email a few days ago to Igor
Pecovnik , who
is the Debian ARM developer . He has been patching the Debian source
for the
BananaPi R1 for a while now , and maintains the R1 patches and
scripts and dts .
My question was if he could submit those (lamobo R1) BananaPi R1
patches for
the dts back to Denx . That way they would be in the mainline and the
benefit is
that all Distros would have access to them not just Debian . Also it
would be
less work for him maintaining the patches with every release of
u-boot . He and
Tomas Kaiser went through the exercise of fine tuning the GMAC_TX_DELAY
specifically for the R1 to improve the Ethernet throughput .This
parameter is
there to compensate for the physical board layout , length of tracks
etc. . They
arrived at the setting of 4 compared with generic bananapi setting of
3 .
Upstream u-boot sunxi / allwinner support maintainer here. I would
love to
see BPI R1 defconfig + dts get submitted upstream officially, I will
happily merge them in u-boot and I'm sure the kernel devs will take the
dts too, assuming it passes review.
But it seems lots of people are working on the BPI R1, but no-one is
submitting patches upstream :|
Find my patches (dmesg fix and b53 switch driver) with latest release
Fedora kernel versions, please integrate it.
