Help with Inteno XG6846

For Developers
1

Hi to all

i have a few XG6846 device
they are working well, and the 6th port (SFP) is helping me a lot
always needed +1 port :slight_smile:

my problem is that factory firmware is very limited, so i like to put OpenWRT on it to gain some SNMP information, etc
Nothing special, but i like OpenWRT look&feel
I itend to use these devices as smart L2 switch

i tried to compile own FW for 96328avng, older v4.x and latest v5.x kernel
Initram image boot from network, everything looks fine, execpt, the main thing :frowning:
there is no network

swconfig shows the chip, but every port is down.
Does someone want to help me to port OpenWRT on this device?

here is the original boot log

so, i haved a few hours free and tried again

so far i found these:
red led is working
green led is working
reset button is working
i2c for sfp module is working

        leds {

                status = "ok";
        };

        i2c1: i2c1 {
                compatible = "i2c-gpio";
                gpios = <&pinctrl 23 (GPIO_ACTIVE_HIGH | GPIO_OPEN_DRAIN) /* sda */

and here is i2c dump of sfp

i2c1 is for external CATV module, so there is no use

but, i still does not have any connection
switch is not working
and, what is the next step with SFP ?

4

ok, have eeprom definition in DTS

                sfp1_eeprom: sfp1eeprom@50 {
                       compatible = "atmel,24c02";
                       reg = <0x50>;
                       read-only;
                };

produce these:

dmesg:

now, i am stuck with i2c-0 / 0x56,
read somewhere that this is mdio bus

                mdio0 {
                    compatible = "flx,i2c-mdio";
                    #address-cells = <1>;
                    #size-cells = <0>;
                    reg = <0x56>;

but this is out of my knowledge
any help with this ?

5

well, i found this when compile kernel 5.4

kmod-phylink is not available in the kernel config - generating empty package
kmod-sfp is not available in the kernel config - generating empty package

so, if i get it right, kernel for broadcom does not support these modules ??

Hi

I have one of these switches as well. How far did you come in your development?
Can I test your image?

7

hi @mrhaav

it is abandoned project, so i have no left any old DTS / images
sry

8

Ok
Thanks for your response!

9

Not a bad idea to revive it. Perhaps some of the switch experts might have some useful pointers for the SFP stuff. @svanheule ?

10

well, if someone need it
i found
XG6846_4.12ITT01.83_20161115_consumer_release.tar.gz in my archive
it is tarball from manufacturer

11

Not sure I can help much, but have you looked at some of the DTS files in the realtek target? You'll need to have (define) an I2C bus, and connect that to an sfp node. See for example rtl8380_zyxel_gs1900-10hp.dts.

Hi
I'd be happy to have a copy of XG6846_4.12ITT01.83_20161115_consumer_release.tar.gz.

ok, uploaded to Mega

@mrhaav do you think you'd be able to get this going?

First challenge is to get a DTS fleshed out.

@NPeca75 are there any particular bits aside from above that were difficult or guessed? Or is everything there in the source?

Hi

I don´t know. But, I can summarize what I know.
Board: BCM96328avng
CPU: Broadcom BCM63281SKFBG Arch. BMIPS4350
Switch: Marvell 88E6352-TFJ2

Board
Board1920×2134 509 KB

COM port: 115200N8 (3.3V)

xg6846
xg6846887×227 159 KB

I have started on a dts file, but it´s not working.
The SFP is connected to i2c0.
I don´t know how the CPU is talking to the Marvell switch. It could be via the MDIO interface. But how do I define the BCM6328 MDIO?
I think the CPU is connected with the RGMII to the switch, all interfaces are 1G interfaces.

All help is appreciated.

Could you compile a consumer_release image?
When I run make PROFILE=XG6846_ITT it failes to download the toolchains_bcm963xx_4.06L.02.tgz.

17

Here is the toolchain mentioned in the consumer_install script. uclibc-crosstools-gcc-4.4.2-1

I've not tried that one. But somewhere on flashback forums, there's a guy claiming to have newer source drops, and being able to compile.

@NPeca75 could you compile the source?

18

Isn't it already defined in .../bmips/dts/bcm6328.dtsi?

1G capable - they're auto-sensing.

The above DTSI already defines a switch. But what does the make menuconfig present?

I think ./kirkwood/files/arch/arm/boot/dts/kirkwood-ea3500.dts has an example.

Try also ./qoriq/files/arch/powerpc/boot/dts/fsl/watchguard-firebox-m300.dts or ./mvebu/files/arch/arm64/boot/dts/marvell/armada-3720-gl-mv1000.dts.

I think a grep for phy-mode = "rgmii"; should find some examples of how to connect things.

19

Here's an addition to target/linux/bcm63xx/image/bcm63xx.mk to get it to show up in make menuconfig.

Maybe this will give partitions in the DTS:

        status = "okay";

                        };

                        nvram@ff0000 {
                                reg = <0x0ff0000 0x1000000>;
                                label = "nvram";
                        };

                        linux@10000 {
                                reg = <0x10000 0xff0000>;
                                label = "linux";
                                compatible = "brcm,bcm963xx-imagetag";
                        };
                };

        };
};

Don't see any point in adding USB (can document it and comment it out) unless something is connected via USB, even though the hardware may have a controller. Just more init time and kernel memory.

Hi @systemcrash,

I'm trying to use the consumer_install source as well to create my own version of the 01.83 version of the firmware. I've already set up an old Fedora 16 VM with the dependencies needed and successfully compiled the firmware. The thing is when I later on test the firmware out on one of my XG6846's the firmware does not load completely and I get an CPU exception. Anyone else who successfully compiled it? And if, what dependencies och pre-requirements are you using?
I'm also looking for a newer version of the source that could be compiled.

As you mentioned, I think I'm "the guy" you are referring to that claimed have compiled it. I've managed to extract an old firmware and edit the file system in that file and then been able to reconstruct it and successfully loaded it into the XG6846. I've not been able to compile the firmware from source.
