Support for Strong 1200

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?

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:

FYI - snapshot support for MTC Wireless Router WR1201 (aka STRONG Dual Band Gigabit Router 1200) has been added with https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=30a7ab8f61c8a5f1a4428f8c7cf9a1d6a12b096b

snapshot images are available for download.

vk496 · December 1, 2018, 12:31am

Hello,

Thnks for the info. In addition to LuCI, do you know which packages are included into release images?

I didn't found buildlogs of release images and I'm not sure which are the exactly differences between snapshot and release.

musashino · December 1, 2018, 4:07am

Please see config.seed.

vk496 · December 1, 2018, 4:35pm

Thnks so much!

I've updated the images with luci and the packages that usually are in release images.

madroal · February 7, 2019, 12:05pm

Good Morning,

I have the Strong 1200 router, when installing firmware openwrt gave an error starting and now I can not get it to work.
I can access by ssh and putty, is there a solution?

P4R4D0X · February 10, 2019, 11:06pm

There's another rebrand of this MTC Wireless Router WR1201 for the US market.

https://www.hootoo.com/hootoo-ac1200-dual-band-wireless-router.html

Model number HT-ND001 and should have the same WR1201-ZC01-01 board as well. Thankfully there is a firmware file for this one that you can get from their website that you can find below.

Please, describe better what you exactly did and what is happening right now.

vk496 · February 20, 2019, 4:37pm

Nice!

Maybe someone have this one and could report us if it works as well as with Strong.

kriob · February 25, 2019, 5:28pm

Hi, the Strong 1200 working for a month without any issues with latest snapshot without LuCi because I used it just for internet access nothing more. The performance is excellent. So thank you for your effort

kriob · February 28, 2019, 4:41pm

Hi, accidentally I downgraded via sysupgrade -F and now router is bricked with blank configuration. How can I manage to login? with serial or via usb?

vk496 · February 28, 2019, 5:32pm

Probably you can access to the router through OpenWrt Failsafe mode (99%). In the worst scenario, you need to open the router and connect through Serial GPIO with a USB-to-TTL adapter.

kriob · March 8, 2019, 8:53am

Hi, I have tried via Failsafe mode but with no success. There is no blinking led. Anyway, I will try with serial but can you confirm that this is the GPIO ports on the board ? (with red line on the picture):

Thanks

I just got the HooToo HT-ND001 version of this router to play with, loaded up an OpenWRT snapshot following the instructions, and I noticed that /proc/cpuinfo was only showing 1C/2T. After looking here, I saw that this matched with the info shown here for the Strong 1200 version of the router. Being the curious sort, I opened up my router and popped off the heat sink to see if the cpu was really the single core MT7621ST. However, what I found was a proper dual core MT7621AT.

So, a look at the u-boot source for similar MT7621 routers (since the specific source for the HooToo HT-ND001 / Strong 1200 / MTC WR1201 didn't seem to be available) indicated that it was likely that the u-boot used was not configured with dual core support turned on when it was built. Luckily, the way they had structured the initialization code, indicated that a 1 bit patch of the u-boot image (to set the "more cores" count during initialization from '0' to '1') might solve the issue an properly enable the second core.

So, I saved a copy of the the original HooToo HT-ND001 u-boot partition off to my PC did some quick disassembly, and produced a patched (changed 1 whole bit) u-boot image that has the proper core count set for the MT7621AT. After using the kmod-mtd-rw module to allow writing the image to the correct mtd partition (which OpenWRT normally keeps read only for safety) and rebooting, I now have 2C/4T showing inside of OpenWRT.

From looking here, the u-boot bootloader partition that I dumped from the HooToo HT-ND001 is identical to the one posted here for the Strong 1200 (SHA256 match), so it should work the same on either router.

For any highly adventurous sorts, I've posed the 2 u-boot files (original and modified) here on my google drive. I've not included further instructions at the moment, as the risk of bricking your router if something goes wrong flashing the bootloader is VERY VERY HIGH. I've only done this on my own personal HooToo router, which I had physically verified contained the MT7621AT chip.

Is there a way to check the processor short of tearing the heatsink off? Kinda hoping to not accidentally destroy things.
