Does this box have Wifi chip?

Quote

I think it is becase of the GPON/EPON support. Maybe F660 is more similar to google GFRG110.

No, I don't think GPON/EPON has anything to do with thisinterrupt. I meant that confirms the device is eth1 in the avanta.dtsi.

eth1: ethernet@70000 {
                        compatible = "marvell,armada-370-neta";
                        reg = <0x70000 0x4000>;
                        interrupts = <7>;
                        clocks = <&gate_clk 0>;
                        status = "disabled";
                };

That's mdio address f1070000.

bodhi,

Yes this box do have a wifi chip. The wifi chip is RealTek RTL8192CE. I haven't worked on the wifi module yet. But I believe it won't be so hard as ETH device.

I believe the order of two eth device in avanta.dtsi is upside down. So I swapped the two eth nodes in avanta.dtsi. (According to the stock log of mi424wr rev i, It uses eth1)
However, that's same as just using eth1 in the dts.

bodhi,

I have tested it. Ethernet is completely working. I can connect to the terminal with telnet. The next thing is WIFI chip.

8086k,

Please post the DTS, DTSI and DTB.

bodhi,

Can linux 5.11 kernel drive the eth device of 88f6560 now? I am trying to update openwrt version.

bodhi,

This is the DTS file of F660. It's for linux 3.14 kernel. It is not very perfect but works well.

8086k,

I did not see where your changes are in these files.

bodhi,

There are some details changed.
First, I commented out these codes

	phy0: ethernet-phy@9 {
		reg = <9>;
	};

&eth1 {
	status = "okay";
	phy = <&phy0>;
	phy-mode = "rgmii-id";
};

Next, I changed

		cpu-port-0 = <5>;
		cpu-port-1 = <6>;

into

		cpu-port-0 = <4>;
		cpu-port-1 = <5>;

I also changed the eth nodes in avanta.dtsi into this.

		eth0: ethernet@70000 {
			compatible = "marvell,armada-370-neta";
			reg = <0x70000 0x4000>;
			interrupts = <7>;
			clocks = <&gate_clk 0>;
			status = "disabled";
		};

		eth1: ethernet@74000 {
			compatible = "marvell,armada-370-neta";
			reg = <0x74000 0x4000>;
			interrupts = <11>;
			clocks = <&gate_clk 19>;
			status = "disabled";
		};

I believe you can see the differences.

bodhi,

There is a very annoying problem on the uboot of F660. It doesn't run bootcmd directly. Instead, It will read the kernel into ram and check the image. If it doesn't pass, U-boot won't continue to run bootcmd. So everytime I must enter the uboot console to boot the openwrt kernel manually. Can you crack the uboot a little?

8086k

8086k,

> cpu-port-0 = <4>;
> cpu-port-1 = <5>;

Thanks. It confirmed the similarity with the MI424WR-rev-I. I've looked at the GPL source and discovered that the CPU is port 5.

> I also changed the eth nodes in avanta.dtsi into
> this.

I have some doubt whether mvneta can be used in the latest kernel (eg. kernel 5.11.4) for these boxes. mvneta has been significantly evloved during 3.x.x to 5.x.x kernels. I will try going back to the Kirkwood driver to see it is a better fit.

=====

Updated: CPU is port 5.

Sure, post the serial bootlog with printenvs.

The bootcmd must be changed permanently to boot Openwrt and fallback to boot stock (if it is possible).

bodhi,

Exactly, I think the way to solve it is to modify the assembly code to make the uboot continue when the check is not passed. But I am very poor at ARM assembly code. So it is too hard for me to do that. The cheking part seemed not to be included in bootcmd or any other envs.

How can we sign the new uboot image? As far as I know, bootrom won't boot an unsigned uboot image.

No need to do that. Sometime u-boot has a quirk that we can use. Or if GPL source is available then rebuild stock u-boot.

This u-boot is quite old, it does not have signature.

No Version Available on Flash.

This is a simple checksum failed, or the kernel image on flashed was corrupted or wiped out. So your stock FW is not good any more.

The thing to do here is to make it permanently booting into Debian or OpenWrt.

Not yet. I don't really have much free time to do any research.


=======

I don't recall if you have tried kwboot with the stock uboot image?

Before we attempt to save envs in u-boot console, it is best that you try kwboot so there is a rescue path if something goes wrong. See example here.

bodhi,

Do you know how to solve the serial interrupt problem? It happens almost everytime when I turn on my box.

I am busy making patches to put my changes into the builder now, I will try kwboot later.

8086k

bodhi,

I didn't change any of the envs because changing them can't make the uboot boot openwrt automaticly(the checksum before running bootcmd stopped it). So I use these three commands to boot openwrt.

wdtdbg watchdog 0 (disable watchdog)
nboot 0x2000000 0 0x80000 (read kernel from NAND to RAM)
bootm (boot kernel from RAM)

This box only have a 32MB NAND flash so I think openwrt is better than debian for it.

This box only have a 32MB NAND flash so I think openwrt is better than debian for it.

You can run Debian on USB. That's what I meant.

==========

For now, see if you can make it boot permanently to OpenWrt.

Interrupt serial console at countdown and

setenv bootcmd_openwrt 'wdtdbg watchdog 0; nboot 0x2000000 0 0x80000; bootm'
setenv bootcmd_stock 'setenv bootargs $(console),$(silent) root=/dev/ram0 rw load_ramdisk=1 rdinit=/sbin/init $(mvNetConfig) $(mvPhoneConfig) mem=$(memsize); bootm 0x2000100;'
setenv bootcmd 'run bootcmd_openwrt; run bootcmd_stock'

and then

boot

After it booted successfully, reboot and

Interrupt serial console at countdown and

setenv bootcmd_openwrt 'wdtdbg watchdog 0; nboot 0x2000000 0 0x80000; bootm'
setenv bootcmd_stock 'setenv bootargs $(console),$(silent) root=/dev/ram0 rw load_ramdisk=1 rdinit=/sbin/init $(mvNetConfig) $(mvPhoneConfig) mem=$(memsize); bootm 0x2000100;'
setenv bootcmd 'run bootcmd_openwrt; run bootcmd_stock'

Now this is where kwboot is important. The next command will save the envs to flash. So there is some small risk that it could mess up your FW (kwboot will enable the rescue if the FW is corrupted).

Do this at your own risk:

saveenv

Now the envs should reflect what you have just saved

printenv

If it looks good

reset

and let it boot automaticaly all the way into OpenWrt.

I have told you the check to the kernel image is run before boot_cmd. It isn't contained in the env. If you use hex editor or ida to view the uboot image, you will find it out. The problem is I can't understand the assebmly code.

There is a chinese post which described it in detail. But the author is not very friendly so I can't get the cracked Uboot image from him.

OK so that's good to know. It's typcial of some NAS manufacturers to do something like this. The bootcmd got reversed to internal hardcode string.

Now, the hard part is not how to change machince code. That is actually kernel image checksum. It can be modified to put the OpenWrt payload in,or calculated for the OPenWrt payload, but we don't know which algorigthm this u-boot uses, whether it's a CRC like in typical older NAS, or some other. I would bet it is a CRC checksum.

So before you spend more time on this topic, I think you should try kwboot.

The u-boot binary for MI424WR-rev-I from bkallus upload:

https://forum.doozan.com/read.php?2,78499,116194#msg-116194

If you can kwboot it, chance is that will run OpenWrt on NAND.

If there is a problem because it's a different HW, we can deal with it.

bodhi,

OK, I will try kwboot first. Mi424wr's Uboot is certainly not suitable for F660. They have different NAND and ETH config.

That's not really relevant, yet. All you would care is to boot it successfully, and then worry about the differences.

And by the way, I don't believe that person on the Chinese laguage forum you posted the link to . Why reporting all that he accomplished and then no binary to share? the process he described was correct (albeit a bit redundant), but you can learn all that by googling .

bodhi,

I've browsed all the information I have, then find this https://lists.denx.de/pipermail/u-boot/2012-June/125700.html The F660 of the author of this page is running an older version of U-Boot I think. This version of U-Boot shows more detail of the checking process. I can't find any available download link of this version of U-Boot.

Ignore this, I just click on the wrong place and post this message.

I've spent some time searching the GPL source for info

- The CPU port for MI424WR-rev-I is port 5.
- The PHY for switch is 8 (we knew that from Claudio's DTS).
- PON is an option for MI424WR-rev-I in the code, look like it can be turned on for other variants of this 6560 SoC.
- The Ethernet driver is mvneta, but a quite old version (about 10 years).

I think currently I might be seeing an old mvneta bug (irq related) from long time ago. The mvneta driver in mainine Linux is working well for the Armada SoCs (Armv7), but has never been used for Kirkwood or other Armv5 SoC such as this 6560.

It could be due to the fact that the mvneta code was architected to run with multi-core, and for single core SoC, it has some problem. However, we are using this for the Mirabox and RN102 (Armv7) in non-SMP kernel successfully! so my theory might or might not be correct.

bodhi,

I have tired the rtl8192ce driver pack in openwrt. It doesn't work. I'm quite sure rtl8192ce is using pci-e bus. And the active pci-e device in device tree is pcie1,0. What do you think the problem is? The driver or the pci-e port id?

bodhi,

I have tried kwboot. It interrupted the normal boot successfully, but kwboot didn't give any other results. It stuck.

user@ubuntu:~/kwboot$ ./kwboot -t -p -B115200 /dev/ttyUSB0 -b mtd0-u-boot.img
Sending boot message. Please reboot the target...-

This is the result when I was using a kirkwood image provided by another forum. When I was using my backup or your mi424wr rev i uboot, it printed this.

user@ubuntu:~/kwboot$ ./kwboot -t -p -B115200 /dev/ttyUSB0 -b uboot-revI-128MbFlash.bin
uboot-revI-128MbFlash.bin: Invalid image.

This is the command I used:

kwboot -t -B 115200 /dev/ttyUSB0 -b uboot-revI-128MbFlash.bin  -p

Look at the file info, too

file uboot-revI-128MbFlash.bin

The PCIe ports should work fine. But try both PCIe ports in the DTS.
