Hi, everyone!

The router uses MT7628+MT7610 solution, 32MB MX25L25635FMI SPI flash, openwrt_chaos_calmer_v15.05 sdk.
It failed to boot. Please help me.
The serial port prints information as follows:

If I use another SPI flash, S25FL064PIF instead of MX25L25635FMI, the router can boot successfully. Serial port information as follows:

1. I changed the file: openwrt\target\linux\ramips\dts\MT7628.dts. But it's useless.

-------------------------------------------------------------------------

/include/ "mt7628an.dtsi"

/ {
compatible = "mediatek,mt7628an-eval-board", "mediatek,mt7628an-soc";
model = "Mediatek MT7628AN evaluation board";

memory@0 {
device_type = "memory";
reg = <0x0 0x2000000>;
};

pinctrl {
state_default: pinctrl0 {
gpio {
ralink,group = "i2c", "jtag";
ralink,function = "gpio";
};
};
};

palmbus@10000000 {
spi@b00 {
status = "okay";

m25p80@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "en25q64";
reg = <0 0>;
linux,modalias = "m25p80", "en25q64";
spi-max-frequency = <10000000>;
m25p,chunked-io = <32>;

partition@0 {
label = "u-boot";
reg = <0x0 0x30000>;
read-only;
};

partition@30000 {
label = "u-boot-env";
reg = <0x30000 0x10000>;
read-only;
};

factory: partition@40000 {
label = "factory";
reg = <0x40000 0x10000>;
read-only;
};

partition@50000 {
label = "firmware";
reg = <0x50000 0x7b0000>; <----- change 7 to f, it's still failed to boot.
};
};
};
};
};

2. I change the file: openwrt\target\linux\ramips\dts\mt7628an.dtsi , add “ root=/dev/mtdblock3”, mtdblock0~3, the router is still not work.

--------------------------------------------------------------

before:

chosen {
bootargs = "console=ttyS0,57600";
};

after:

chosen {
bootargs = "console=ttyS0,57600 root=/dev/mtdblock3";
};

Hi
please use git sources for OpenWRT/LEDE

here are the steps for Edimax BR 6478 V2
https://forum.openwrt.org/viewtopic.php?id=67192
please you new new "Device" name for support

Hi, elektroman,
I'm a new person to openwrt. Could you tell me what's wrong with the serial log? And I'm sorry, the article about Edimax BR 6478 V2 is hard for me.
You mean, LEDE is better than OpenWRT chaos calmer?
My router is K6512, it is nearly the same design as D-link DIR-816, both AC750 router, MT7628+MT7610E chips.

My router is K6512, it is nearly the same design as D-link DIR-816, both AC750 router, MT7628+MT7610E chips.

So is the both devices are almost the same, take the DIR 816 DTS as blueprint for your (new) K6512 DTS, so you can see the differences after (If there any)

You can search in the git source tree for the "build recipe" for the DIR-816, they are maybe some hints aka partition number for the MTD device or other magic numbers here

LEDE is the successor of OpenWRT, last update of OpenWRT git is around may this year, all devs moved to LEDE. Using SDK for a new device is a bad idea.

The best way (here) is to try and fail, use initramfs for target (in menuconfig).
Some hint running initramfs. disable "fail safe mode" in image creation.

FWIW:
I don't memorize all this stuff, I must search this all by my self.
But this "git" tool will help you a great deal ...
I know this is hard for a beginner, everybody know this.
And in the Edimax thread you will see my git tree and see what steps I've done.

Thank you for you advices!
I will try it! And I will use LEDE instead of chaos calmer.

I modified the feeds/base/package/devel/perf/Makefile.

define Build/Prepare
#       $(CP) $(LINUX_DIR)/tools/perf/* $(PKG_BUILD_DIR)/
endef

Then make again. There is another error: cannot find the Makefile.perf file and stop compiling.
I download the tar from: https://downloads.lede-project.org/snap … ps/mt7628/
Is it right?

No, don't use the SDK !!
It's normally used for building a firmware, but you are (currently) far from this

Please enter this command into the shell

cd ~
git clone git://git.lede-project.org/source.git LEDE
cd ~/LEDE
./scripts/feeds update -a
./scripts/feeds install -a

This will setup the LEDE build enviroment in ~/LEDE

cp target/linux/ramips/dts/WRTNODE2P.dts target/linux/ramips/dts/K6512.dts

I use the WRTNODE2P device here as a sample for the *new* DTS file from your board.
Add these lines to target/linux/ramips/image/mt7628.mk

define Device/k6512
  DTS :=  K6512
  IMAGE_SIZE := $(ralink_default_fw_size_8M)
  DEVICE_TITLE :=  K6512
  DEVICE_PACKAGES := kmod-usb2 kmod-usb-ohci kmod-ledtrig-usbdev
endef
TARGET_DEVICES += wrtnode2p

This is for your device with a 8MB flash, but (and this is a big but) with normal flash layout.
u-Boot, u-Boot-env, factory (with some info about wifi), and firmware.
firmware will parted up after boot into
kernel, rootfs and yffs2

Boot this *only* via TFTP
And test, some parts are missing leds, buttons and of course the correct flash layout.

Thank you, elektroman!

I thought, the lede source from git and web download page were the same. You mean, they are different.

I get the git source code, and compile it. This file download from LEDE web page: lede-sdk-ramips-mt7628_gcc-5.4.0_musl-1.1.15.Linux-x86_64.tar.bz2, must compiled on x86_64 ubuntu OS, but the git source code can be compiled on x86_32 ubuntu OS.

The compiling need very long time, and it's not finished. As so far, I find only this difference.

There is another question, which branch is tested ? I don't need the newest version, but the tested one.

lede_git/source$ git branch -a
* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

No completely,
but with the git sources you can track your own changes

And this is the main part of using git here.
oif you want to build for a existing device you can use the SDK

Again not quite right.
with the git sources, you buidl your own toolchain for your target.
And it's completely irrelevant on which platform/arch.
You can build this also on your raspberrypi, if you have enough time.

You have cloned the whole repository.
By definition "master" is upstream.
It depends and the view, if it's stable of testing.
In OpenWRT/LEDE terms this is testing and if you do

git branch -av

you will see all SHA1 hashes are the same.

remote/origin
are the branches from your "origin" repository your initially cloned from.
master
is your local.

I forgot to tell, please create a local branch you can work on with

git checkout -b router

with "router" as your local branch name.

Hi, elektroman,

1. I compiled the git lede code, and the router boot ok now. The router is mt7628 + mt7610. The mt7628 is for 2.4GHz, and the mt7610 for 5GHz. Now the 2.4GHz is ok, but cannot find the 5GHz interface.

2. I copy the mt7628 dts/dtsi file from git lede code to chaos calmer openwrt code, but it's still failed to boot. I don't know why.

Hi, elektroman, I find two broadcom chip router. One use the same design with netgear R6300v2, the other is same as netgear R7000. I compiled the git lede source code for the two router, and I choose the config file for R6300v2 and R7000.

When I flashing the firmware for netgear products into my router, the seiral print: TRX magic number error. I find that, the netgear's router firmware has a 58 bytes head more than my router, so I cut it off (use the dd command). Then flashing is ok.

But both router failed to boot.

I know the initramfs is a very importand tool for debugging. Can you tell me how to use it after compiling? Is there any initramfs example for broadcom chip router?

Hi, elektroman,
1. I compiled the git lede code, and the router boot ok now. The router is mt7628 + mt7610. The mt7628 is for 2.4GHz, and the mt7610 for 5GHz. Now the 2.4GHz is ok, but cannot find the 5GHz interface.
2. I copy the mt7628 dts/dtsi file from git lede code to chaos calmer openwrt code, but it's still failed to boot. I don't know why.

This is the big thing why you should use git tool.

Take the change form step one and commit them with git.

For the 5GHz maybe they is a missing pcie entry in the DTS or missing eeprom entry.
check the files in target/linux/ramips/dts/
For the eeprom entry in the 5Ghz section use

hexdump -C $DEV

i.e with /dev/mtd2

search for patterns with
0x76 0x12
or
0x76 0x68
these are values form mt76x2_pci.c

The firmware compiled from lede git source code can run on netgear r6300v2. But 5GHz wireless SSID is none. I cannot find the interface when I use the ifconfig command.

The r6300v2 has 128MB nand flash, K9F1G08U0D, made by samsung. My BCM4708 router has same source design with r6300v2, but use Spansion 128MB nand flash S34ML01G100TFI00, instead of samsung one. I think this diffrence make my router failed to boot.

Hi, elektroman, when "make kernel_menuconfig", I disable the "Seama firmware parser" and compile a new firmware. There is not "could not find valid ONFI parameter" print now. But still "mtd_read error while parsing" in this function:

static int bcm47xxpart_parse(struct mtd_info *master,
                 struct mtd_partition **pparts,
                 struct mtd_part_parser_data *data)
{
...

        /* Read beginning of the block */
        err = mtd_read(master, offset, BCM47XXPART_BYTES_TO_READ,
                   &bytes_read, (uint8_t *)buf);
        if (err && !mtd_is_bitflip(err)) {
            pr_err("mtd_read error while parsing (offset: 0x%X): %d\n",
                   offset, err);
            continue;
        }

...
}

After large times print, the router failed to boot. Maybe the driver is wrong?

About initramfs, I find this command: boot -tftp -elf 192.168.1.2:/brcm47xx/openwrt-brcm47xx-vmlinux.elf

I will try it.

Error happens in : mtd->_read() .
Maybe lede doesn't support my nand flash?
If I want it support Spansion 128MB nand flash S34ML01G100TFI00, how to change the code?
Add something to nand_flash_ids[] ?

I debug the nand flash driver. I find that -74 stands for -EBADMSG error. After power on, the router call the nand_read(), and continue to call nand_do_read_ops() function. Sometimes return ok, and sometimes return -EBADMSG. I don't know why.

static int nand_do_read_ops(struct mtd_info *mtd, loff_t from,
                struct mtd_oob_ops *ops)
{

...
    if (ecc_fail)
        return -EBADMSG;

...

The nand flash ECC has some error? My friend tell me, my router use : 1-bit Hamming, 16B spare, 512B sector.
How to change the source code?

With the error ...

For the sector size 2048 is typical , 512 is the logical size

Normally not needed, most vendors are supported in vanilla kernel.
check your physical address.
Check you DTS file (please post)

And please
I can't distinguish between two (almost) identical devices in one thread.
And I do not begin with this king of sh*t, anyway
.. Sorry for that, but I must to be clear here

And you can't do it either, you are beginning to mess around

Thank you, elektroman!
My router is similar to netgear r6300v2 and asus rt68u router. So I compiled the lede code and get firmware for r6300v2 or asus rt68u. I flash the firmware to my router. In another word, I use the dts or physical address for these two types router. Is it a good idea for a new person(like me)? If this is OK, I will make my own dts file. I'm not 100% sure of difference between my router and r6300v2.

I know r6300v2, rt68u, and my router are BCM4708+ 4360 + 4331 solution, 128MB nand flash( 2KB/page ). They use the same broadcom hardware design. The lede firmware runs OK on r6300v2, but failed on my router.

You mean start address?

check your physical address.

Is it ?

Starting program at 0x00008000

My router also use 0x00008000 if I flash the broadcom sdk firmware.

The boot information on r6300v2 is as follows:

I change the kernel config: support software BCH ECC, nand ECC SMart Media Byte Order.
But it still failed to boot.

I can see, brcmnand_read_by_pio() function returns -74 when read oob data. Sometimes OK, and sometimes failed when nand_do_read_oob() called.

After flashing broadcom sdk firmware, my router print :
