00:45 <Hauke> Wizzup: I just saw that the u-boot spi driver only works for the sun4i generation and not for the sun8i generation

00:46 <Hauke> it looks like the more recent SPI controller uses different registers and bit offsets

00:46 <Hauke> should I create a new driver like it was done in Linux?

00:47 <Hauke> the flow in the driver will probably be very similar, but the registers are different

00:49 <Wizzup> Hauke: the driver we wrote also works on newer generations

00:50 <Wizzup> tested on H3 (I think) and definitely A64, and also A33 I believe

00:50 <Wizzup> I am not sure what the Olimex employee did with it, perhaps he's enabling it only for sun4i and sun7i because that's the hw he has easy test access to?

00:50 <Wizzup> Sorry, btw, I need to get sleep now.

00:54 <Hauke> Wizzup: ok I will try this on my H3

12:54 Jagan has quit [Ping timeout: 260 seconds]

13:26 <Hauke> icenowy[m]: yes

13:28 <icenowy[m]> hauke: for lede sunxi did you test bpi-r1?

13:29 <icenowy[m]> currently the only sunxi device with switch

13:29 <KotCzarny> well, opi r1 might be treated as router too. with stretched imagination

13:30 <KotCzarny> in fact it might be even better than bpi-r1

13:31 <KotCzarny> 4 cores, physically separated ports

13:32 <Hauke> icenowy[m]: I do not have a bpi-r1

13:33 <Hauke> the opi r1 only has 100MBit/s and the wifi card is not supported by LEDE

13:33 <KotCzarny> but it also has few usb ports available

15:07 <romanis> hello, i've got a running debian stretch on a SD-card of my cubieboard2. Is it possible to transfer the installed system to the NAND?

15:07 <romanis> i've already enabled the NAND in armbian-config, but i can't access it and it's giving me many I/O errors in dmesg.

15:08 <romanis> uname: Linux cubieboard2 4.13.16-sunxi

15:17 nuuuciano has joined #linux-sunxi

15:24 <icenowy[m]> Hauke: you can try to add out-of-tree driver to lede

15:24 <icenowy[m]> I think you are taking over the maintaince of sunxi lede now?

15:25 <Hao> ennnnn, has anyone used video encoder on sunxi chip ???

15:25 <icenowy[m]> P.S. bpi-r1 is a big problem as the mainline switch solution is DSA but the LEDE solution is swconfig

15:26 <Hauke> icenowy[m]: LEDE also support DSA switches

15:27 <Hauke> we just do not have a migration script from a swconfig configuration to a DSA configuration

15:28 <icenowy[m]> hauke: it's heard that the DSA driver of b53 is buggy

15:28 <Hauke> out of tree driver are no problem, I prepared here some: https://git.lede-project.org/?p=lede/hauke/staging.git;a=commitdiff;h=7434449143d6675b395ce4313ad4c99e780c73d3

15:28 <Hauke> I haven't looked at the b53 DSA driver

15:28 <icenowy[m]> maybe I should send a PR with switching back bpi-r1 to swconfig

15:29 <Hauke> b53 is the openwrt swconfig driover with a dsa interface

15:29 <icenowy[m]> I suggest you just use https://github.com/jwrdegoede/rtl8189ES_linux

15:29 <icenowy[m]> and it seems that luci is not so well integrated into dsa?

15:29 nuuuciano has quit [Ping timeout: 268 seconds]

15:29 <Hauke> do I need a different driver for each chip different realtek chip?

15:29 <icenowy[m]> yes you get it

15:30 <icenowy[m]> the repo above have branches for 8189es (master) and fs (rtl8189fs)

15:30 <icenowy[m]> 8723bs guy is in kernel staging

15:30 <Hauke> is there an overview which driver works best for which realtek chip?

15:31 <icenowy[m]> no "best"

15:31 <KotCzarny> for bpi-r1, reading https://github.com/armbian/build/issues/511

15:31 <icenowy[m]> for out-of-tree ones, there's only "work"

15:31 <KotCzarny> might shed some light about history and current status of dsa support for it

15:31 <icenowy[m]> Kc: it'

15:31 <Hauke> ok then somehow work ;-)

15:31 <icenowy[m]> it's not openwrtish

15:31 <icenowy[m]> ;-)

15:32 <Hao> icenowy[m]: what is dsa...？

15:32 <KotCzarny> but might light up some dsa discrepancies if one starts converting the scripts ;)

15:32 <icenowy[m]> distributed switch architecture

15:32 <icenowy[m]> hauke: do you consider switch sunxi to 4.14?

15:32 <Hauke> you can just create a normal bridge in OpenWrt / LEDE and this should then get offloaded to the hardwaer with DSA

15:33 <Hauke> icenowy[m]: yes I consider to go to 4.14 as this makes maintaing easier

15:33 <icenowy[m]> Hauke: I want the same experience with my TP-Link router with Atheros chip ;-)

15:33 <Hauke> leyy stuff to backport

15:33 <Hauke> less

15:33 <icenowy[m]> yes

15:34 <icenowy[m]> I think then only needed backport now is opi-r1 support?

15:34 <icenowy[m]> oh and dwmac-sun8i

15:34 <Hauke> stmmac support was only added in 4.15

15:35 <Hauke> I have a branch here: https://git.lede-project.org/?p=lede/hauke/staging.git;a=shortlog;h=refs/heads/kernel-4.14-sunxi
