Flash OpenWrt

Due to OEM firmware limitations, is not possible to flash directly the OpenWrt sysupgrade image. Instead, you need to flash 2 times: first the initramfs, and after the squashfs.

If you only flash the first one, and not the second, you will have a full functional OpenWrt. BUT all config modifications will be cleaned after reboot.

To flash OpenWrt image from OEM web interface, you must flash the firmware 2 times:

In the OEM Web interface (192.168.1.1, psw:admin), go to System Tools > Firmware Upgrade and flash openwrt-ramips-mt7621-mtc_wr1201-initramfs-kernel.bin
After 2min, open OpenWrt interface (192.168.1.1, psw:root), go to System > Backup/Flash Firmware > Flash new firmware image, uncheck Keep settings and flash openwrt-ramips-mt7621-mtc_wr1201-squashfs-sysupgrade.bin

Is crucial to flash initramfs-kernel from OEM or you will get a bootloop!

Hello,

I'm trying to support the Dual Band Gigabit Router 1200 of Strong, a 39€ router .

Thanks

Special thanks to Strong for giving me the device

I managed to boot OpenWrt. For now, I disabled:

CONFIG_MTD_NAND=y
CONFIG_MTD_NAND_ECC=y

My fault, I suposed NAND when really was SPI. With this DTS I can boot into OpenWrt

Hello,

I'm having issues with Ethernet. I have a assigned IP address, but there is no traffic with my computer (static IP config).

However, I can see ARP and Broadcast packages...

I understand that there must be some switch post-config, but not sure how to manage it. Any help?

You need to add the entry for your router to base-files/etc/board.d/02_network (line 118).

	sk-wb8|\
 +	strong,wr1200|\
	u7621-06-256M-16M|\

Thanks for the notes!

Already built and tested, with no luck . Same behavior.

musashino · October 11, 2018, 1:16pm

For that entry in 02_network, you need to use the compatile string in the dts.
So, for your device, if compatible = "strong,strong-wr1201" you need to describe as follows to 02_network:

strong,strong-wr1201

vk496 · October 11, 2018, 1:33pm

Bingo!

Works like a charm. Thnks!

musashino · October 11, 2018, 1:35pm

And, the string based on compatible is used for define Device/{model} in image/mt7621.mk.
Since this string is used for compatibility information added to the firmware, sysupgrade can not be performed if it contains an error.

If compatible = "strong,strong-wr1201", use strong_strong-wr1201 for it.

define Device/strong_strong-wr1201
  DTS := STRONG-1201
  ...
endef

vk496 · October 11, 2018, 1:38pm

For TARGET_DEVICES += strong-wr1201 should be the same, strong_strong-wr1201 ?

vk496 · October 11, 2018, 1:52pm

Okay, thnks for the explanation!

musashino · October 11, 2018, 2:02pm

Sorry, also need to change TARGET_DEVICES += strong-wr1201 to TARGET_DEVICES += strong_strong-wr1201. I had a misunderstanding...

vk496 · October 11, 2018, 2:05pm

Correct, or no option in make menuconfig...

vk496 · October 11, 2018, 11:19pm

Hello,

Anyone know how to get the mask_port of a switch for the leds?

Related to base-files/etc/board.d/01_leds:

strong,strong-wr1201)
	ucidef_set_led_switch "lan_link" "lan_link" "$boardname:green:lan_link" "switch0" "0x01"

I tried different values: 0x01, 0x03, 0x08, 0x10, 0xa, ...

All of them simulate data traffic (or directly not work).

Also, ip link show don't display any difference when the rj45 is connected or disconnected:

This implies that the netdev rule also not work:

ucidef_set_led_netdev "lan_link" "lan_link" "$boardname:green:lan_link" "eth0.1" "link"

In the forum didn't found any info related to this issue...

Hello,

I made some progress. Right now WiFi is working (2.4 and 5 GHz). However, I have problems with SD card reader. After installed drivers for mount fs, I get this error when insert the microSD:

Is a general bug for kmod-sdhci-mt7620?

diizzy · October 15, 2018, 8:30am

To my knowledge the SD driver for MT7620/MT7621 is quite dodgy so don't expect it to be working/stable.

vk496 · October 18, 2018, 2:01pm

Tried another microSD card and work like a charm.

Hello,

After some research, I think I understand why flash squashfs.bin images from the OEM web interface is not working.

When you upload a firmware to the webpage, it get the full size from uImage Data header and not the file size.

That mean, if the full OpenWrt firmware is 7 MB, in the uImage header will appear a size of ~1,8 MB, corresponding to the Kernel.

The main problem is that doing some hacks (set uImage header to 7 MB) WILL flash the whole image, BUT OpenWrt will supose that the Kernel is 7 MB (instead of 1,8 MB) and the boot will fail:
