13:12 <erm67> Hi I got a new 4G/32G S905X3 box, it is labeled X99 Max+, I soldered a serial already, it boots with the meson-sm1-sei610.dtb but it has a Realtek RTL8211F external phy and all sm1 dtb use the internal phy instead so ethernet is not working. Where can I find a sm1 dtb with external phy or someone can help fixing the sei610 one?

13:24 <repk> meson-gxl-s905d-p230.dts seems to use a RTL8211F also

13:30 <erm67> The S905X3 is derived from the g12a, the most similar dtb is the meson-g12a-x96-max.dtb that also uses the RTL8211F, but it segfaults. I copied &ext_mdio and &ethmac from the X96 dtb to the sei610 but it complains that the GPIO has already been taken and eth doesn't work :-)

13:30 <erm67> In fact the X99 max+ is a cheap X96 max+ clone ......

13:32 <repk> what do you mean by it segfaults ?

13:33 <repk> erm67: and yes you need to know on which gpio the phy interrupt is connected

13:34 <erm67> I have extracted the original dtb from the box can I find the gpio there maybe?

13:35 <erm67> it uses kernel 4.9

13:35 <erm67> coreelec boots perfectly

13:37 <repk> If you can bootup old kernel you can find it easily. Or with the old dtb you can try to decompile it with dtc

13:37 <repk> something like dtc -I dtb -O dts -o dt.dts dt.dtb

13:38 <erm67> I did already

13:45 <erm67> http://sprunge.us/MjA6sk

13:45 <erm67> this is the original dtb

13:55 <repk> does not seem to use external phy then

13:57 <erm67> http://sprunge.us/j2Xmb4

13:58 <erm67> segfault with the max-96 dtb

13:58 <erm67> yes it uses rgmii that is external phy

13:59 <erm67> I booted the original firmware

14:04 <erm67> http://sprunge.us/6eOmow

14:04 <erm67> this is the boot log of the original firmware

14:33 <erm67> http://sprunge.us/BCfqNN

14:34 <erm67> and this the boot of the sei610, the eth0 comes up but it doesn't work, it doesn't even sense the carrier pulling the cable off and on

14:40 <repk> the dts from http://sprunge.us/MjA6sk seem to use internal_phy though

14:47 <erm67> I got it from /dev/dtb

14:48 <erm67> maybe it is not used, on board there is definitely a realtek chipset soldered

14:58 <repk> erm67: with the 4.9 kernel what do you have in "cat /proc/interrupts" ?

15:01 <erm67> http://sprunge.us/1yeI23

15:02 <erm67> in /dev/dtb is gzip compressed and binwalk shows 4 dtbs chained, I uploaded only the first one, I try to extract all 4 dtb

15:25 <narmstrong> `[ 23.062886@0] meson6-dwmac ff3f0000.ethernet eth0: Link is Up - 1Gbps/Full - flow control rx/tx` so it uses external phy

15:25 <narmstrong> so you dumped the wrong dtb

15:26 <narmstrong> erm67: simple copy the max-96 dts to include meson-sm1.dtsi instead of g12a

16:48 <erm67> ok thanks

17:26 <erm67> I modified the max96 dtb, it no longer segfault on usb_init but the ethernet still doesn't work

17:26 <erm67> however ethernet works perfectly with emuelec using the sm1_s905x3_4g_1gbit.dtb

17:26 <erm67> http://sprunge.us/0TNR2N

17:27 <erm67> which I dumped here

18:21 <erm67> I also dumped all dtb from /dev/dtb and the 4th is probably the right one: http://sprunge.us/PQmhT0

19:10 <repk> erm67: random guess, do you have CONFIG_MDIO_BUS_MUX_MESON_G12A=y or m ?

19:27 <erm67> I am ushttp://sprunge.us/uDzkiS

19:27 <erm67> Iam using the armbian kernel

19:27 <erm67> CONFIG_MDIO_BUS_MUX_MESON_G12A is m
