Do you mean the Boot Address?
I can´t change the Boot address, it´s still 0xb8000000 even if I load your image again.

I don´t know if this helps.
If I have Boot image (0=latest, 1=previous) : = 0

Booting from latest image (0xb8010000) ...
Code Address: 0x80010000, Entry Address: 0x80286840
Decompression OK!
Entry at 0x80286840

and Boot image (0=latest, 1=previous) : = 1

Booting from previous image (0xb8800000) ...
Code Address: 0x80010000, Entry Address: 0x80286760
Decompression OK!
Entry at 0x80286760

I get the same result even if I load your image in both latest and previous Boot image.

I have tested on my three devices and all have Boot Address: 0xb8000000

84

How typical. I installed my device with the initramfs method before, then I naively flashed the CFE image and thought that was what I was running, but maybe it is actually just my old initramfs-installed kernel that I'm seeing :frowning:

I updated the web page with the two-stage initramfs method, can you see if this works for you?

85

TFTPed your initramfs and sysupgraded but the device rebooted to Inteno FW.

Then I change Boot image (0=latest, 1=previous) : to 1 and reset.
Now it´s booting on OpenWrt!

I have alot of jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00280000 - 0x00590024.
Do you know why?

Is it possilbe to add LuCI? Or is your github repositry updated?

Hey it almost kinda works! :smiley:
Apparently the latest/previous setting is stored somewhere in nvram, I don't know the logic there.

Yeah, with the sysupgrade method we do not erase the remainder of the flash image, so when jffs2 scans that memory it looks like it's something there already. I think it's possible to erase the flash memory from CFE or U-Boot but it's a bit dangerous I think.

I think the free space inside the firmware partition need to be reflashed with magic JFFS2 markers in all empty erasblocks, I think if you do that over the whole "firmware" partition and then flash using the sysupgrade method all of the flash below the images becomes available.

Is it possilbe to add LuCI? Or is your github repositry updated?

My repo is updated and includes a binary version of U-Boot as I haven't created a way to build U-Boot yet, but I will fix that too. You can rebuild with any options you like!

87

I added some instructions for how to erase the flash before installing OpenWrt to my webpage, check it out!

In nvram there is a bootline key. In the value string there is another key/value pair. I think it is p=0 for booting current and p=1 for booting previous.

OK I updated the sysupgrade image on the web page with a version including LuCI and tested and screenshotted and all, so now people should be able to use this as a vanilla router.

Yes, you have made it possible to run OpenWrt on the XG6846! Thanks!
Nice with LuCI.

BTW, the Boot image (0=latest, 1=previous) line disappeared after I erased /dev/mtd1.

It kind of makes sense that the boot image selection disappeared after erasing mtd1, we deleted the secondary boot image altogether :smiley:

Hi
To get the USB interface to work I had to install a jumper at F2. Actually it should probably be a fuse.

image545×585 57.3 KB

Then I added:

&ehci {
	status = "okay";
};

&ohci {
	status = "okay";
};

&usbh {
	status = "okay";
};

to bcm6328-inteno-xg6846.dts.

But, I can´t get the wan and the USB led to work. Does yours work?

94

Nice hack! Once we have the support merged we can add this info to the OpenWrt page.

But, I can´t get the wan and the USB led to work. Does yours work?

My device has no USB port and they have soldered a resistor instead of the LED. But have you tested it from sysfs?

cd /sys/class/leds/green:usb
echo 100 > brightness
echo "heartbeat" > trigger

The WAN LED is connected directly to the Marvell switch I think, so you need to go into the source code and figure out how to activate that I'm afraid... It's at https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/dsa/mv88e6xxx

95

Hmm - fantastic work @linusw :slight_smile:

My device has no USB. I understood that this is for aftermarket updates or configs. Perhaps @merbanan has better understanding. But having USB on a fiber adaptor opens up a few possibilities, at least for the earlier board revisions.

Edit: curious whether you've tried any performance/throughput numbers using openwrt on this.

Hmm - is this normal behaviour? Or is this a result of these errors:

Do you have normal 1500 MTU, @mrhaav ?

An improvement idea would be to add some early timeout for SFP adaptors also:

Some interesting discussion regarding switches + broadcom.

97

Yes, or I have not change anything. This is the log from the first boot.

How do we set a timeout for reading SFP on boot?

98

For that I have no good answer. I think this depends entirely on kernel code, but having some timeout value available for use within DTS files would be helpful.

99

No, it´s not working.
I have to remove

	pinctrl-0 = <&pinctrl_pcie_clkreq>, /* GPIO16 LED USB */

	led_usb_green: led@16 {
		reg = <16>;
		active-low;
		label = "green:usb";
		default-state = "off";
	};

from the dts file, then a can control the USB led with

echo 496 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio496/direction
echo 1 > /sys/class/gpio/gpio496/value

I tried to add

	leds {
		compatible = "gpio-leds";

		led_usb_green: led@16 {
			label = "green:usb";
			gpios = <&pinctrl 16 1>;
			default-state = "off";
		};

but no success.

But I don´t know how to define the USB led in the dts so it is working and visible in the system.

The complaints about MTU size is simply because the mv88e6xx and b53-switch drivers are lacking the appropriate callbacks for setting the MTU. struct dsa_switch_ops .port_change_mtu, also .port_max_mtu is using the callbacks .port_set_jumbo_size() or set_max_frame_size() from struct mv88e6xxx_ops, and for this switch, mv88e6085 in mv88e6085_ops in drivers/net/dsa/mv88e6xxx/chip.c, these callbacks are missing, so anything else than 1500 will fail.

Usually it will "just work" because the switch actually support larger frames than 1500 it's just that the framework don't know if it does or not.

I'm trying to locate a datasheet for MV88E6085 to fix that one. If someone has this datasheet, please share it.

To use a gpio LED it's correct to remove the pinctrl_pcie_clkreq (was wrong in the first place!) then you should probably do:

	leds {
		compatible = "gpio-leds";

		led_usb_green: led@16 {
			label = "green:usb";
			gpios = <&gpio 16 GPIO_ACTIVE_HIGH>;
			default-state = "off";
		};

As it seems it is reusing one of the GPIO lines and it seems it is active high. Using &pinctrl doesn't work I think.

102

I found out that this is actually a MTU size bug in the "enetsw" (on-board switch) on the BCM6328.

I sent a patch and included this in my XG6846 patch stack:
http://lists.openwrt.org/pipermail/openwrt-devel/2023-October/041556.html

103

Yeah, nice, I saw your patchset on the list. Nice work, man.

The folks on the above PR discussion also noted various quirks with MTU owing to Broadcom tags that any internal switches potentially add to frames.

So, as long as the max frame size is less than 1536, the following error should also disappear?:

[    2.340638] b53-switch 10e00000.switch extsw: error -34 setting MTU to 1508 to include DSA overhead

If a user tries to set jumbo frames, would that work or break? Edit: it will break.

@merbanan is a datasheet something you could point us to?

or MV88E6085 ?
