Topic: Realtek SoC support in OpenWrt

Hello the community!

I've been postponing this post since about 2 month, hoping we will get to
some stable quiet bay. But we are still not there so I decided not to wait
any longer :)

We are working on Realtek SoC family support in OpenWrt. Particulatrly rtl8196c,
rtl8196e, rtl8196d and rtl8198. Most of you probably know that Realtek SoCs are
actually Lexra cores (4xxx and 5xxx series) which are modified mips cpus with
few absend instrustions (compared to mips).

There was some interest in rtl8196c based routers seen here, like [1][2][3] and
even rtl8198 [4]. There is also DSL SoC from Realtek [5] but we don't have any
plans to work on that currently.

For now we have rtl8196c + rtl8188re as wifi working pretty stable but several
hacks to OpenWrt build system are needed to compile it. Also we have it
working only with binutils 2.21.1 and gcc 4.5-linaro (4.6-linaro breaks
usb support somehow). Current toolchain patches are based on earlier work of
other OpenWrt members (Florian? Felix?). But we got some support from Realtek
itself and now, looking at their changes and what we had before, we are going
to make gcc 4.8 + binutils 2.22 toolchain.
As for the other chips, rtl8196e boots and seems to be working but without
ethernet and usb and rtl8196d only kernel boot is working (userspace explodes).

Regarding the kernel and drivers we are still at 2.6.30/2.6.32
as this is what can be found in Realtek SDK but major kernel bump is planned.
Wifi driver (rtl8192cd) is already made to be compiled from compat-wireless.
Realtek's code is mostly GPLd or doesn't contain any copyrights so there should
be no legal problems with code porting. Sometimes there are also fake copyrights
(original copyright changed to Realtek).

For those who are interested right now our tree is based on trunk@36713 and all
changes are in realtek-unstable branch here [6]. There are also few snapshot
images here [7]. There is also #nprove@freenode where we are free to talk or
discuss any questions regarding this port. Some also blog a little [8].
Sure we will be glad to get any help and suggestions.
Feedback is also welcomed :)

Our current TODO list looks approximately like this (priorities could be mixed):
- toolchain (gcc 4.8 + binutils 2.22)
- rtl8196e ethernet and usb (newer ethernet driver? toolchain?)
- rtl8196d userspace (toolchain problem?)
- merge arch/rlx/ with arch/mips/, cleanup
- kernel version bump (to 3.10?), this may trigger major driver rewrites
- ethernet switch driver based on swconfig

please consider adding support for RTL8186 as they are also widely spread around

RTL8186 is so Obsolete, I could never get support from Realtek for it. How about this, I can do a trade in program. If you send me your Obsolete Realtek routers, I will give you a discount off an officially supported Realtek router from us.

Re: Realtek SoC support in OpenWrt

anarchy99,

You would want a Dualband Realtek router because the 5ghz radio is backwards compatible with 2.4ghz. You can configure it to also run at 2x 2.4ghz radios similar to what you currently have.

dear roman,
  great job!! ,
i have 2 router with rtl8196C with 4m flash+16MB RAM,

if it can work,i wanna test it later.

Most likely it will work for you already at least partly. Remember that 8196c doesn't have wifi embedded so the routers come with wifi companion chips like rtl8188er or rtl8192re. Choosing the chip is basically a matter of configuration and currently we have no companion chip profiling. But you can change the kernel config directly if you know which wifi chip is soldered on your router.
Also 4MB flash and 16MB RAM is not enough to run web interface so you should be ready to use console only.

Dear Roman,
   i just check that wlan chip,it is rtl8192. how about the bootloader ? need i upgrade it  first?

how to use your image/bin in your site at:https://downloads.nprove.in/snapshots/rtl8196c-gcc4.5-fonluci/

or do you have any full fireware  with the bootloader, with size 4M or 8M.

Well, that's a good sign - it boots :)
The reason is (as you probably suspected) that image is made for 8MB flash. But you can change the sizes as you need from menuconfig (image configuration) and compile your own image. Remember to use the right version of gcc if you want usb working.
Also you can use fw.bin - that's kernel and rootfs. Otherwise you would need two files - kernel and squashfs.

Re: Realtek SoC support in OpenWrt

Dear Roman,
    thanks, i m trying to make the 8M fw, and my memory is only 16MB,it is not large enough,

i'll change it to 32MB/64MB. btw will the  64MB  memory chip(MT48LC32M16A2-75IT 64MB SDRAM SOP 54)  work?

I do not recommend you change the memory unless you compile your own bootloader. The ram is hard locked. But you can change the spi chip as long as you copy the MIB portion. You can also just buy a router from the factory we work for with 8MB flash and 64MB of ram. It will be guarnteed to work out of the box.

Re: Realtek SoC support in OpenWrt

Dear roman,
  i change the SPI Flash to 8MB, and i can  complie it in Redhat systems .
download the new fw with 8MB Flash + 16MB RAM,

the OpenWrt kernel works ,but i have no idear how to connect the router via the WAN/LAN.

WAN (DHCP not work)   ---: [other router with DHCP Server]<----RJ45 Cable---> RTL8196C
LAN (DHCP not work)   ---: PC(dhcp) <----RJ45 Cable---> RTL8196C
LAN (static not work) ---: PC(static) <----RJ45 Cable---> RTL8196C

Re: Realtek SoC support in OpenWrt

Hm, great to see that the effort lives! I think I'd give it a quick test some time soon. So far your commit log looks quite promising.
Meanwhile, this may prove useful if anyone would want to take on the effort (unfortunately, I don't have time for that any more)

https://github.com/nekromant/linux-rlx-upstream

This is my old attempt to boot upstream linux kernel on RTL8196. 8198 would need some extra love.
The rtkload is not required, thanks to BOOT_RAW.
So far, stuff that works:
* Interrupts and related stuff
* earlyprintk
The bad thing is, that lexra core inside the RTL8196 expects to find nop after each ll. So it requires some heavy patching of the assembly macros to work. Right now it boots, and crashes somewhere when the multitasking kicks in.

I'd look at fixing that at the binutils level. gas has a bunch of hacks for processors with that kind of hazard.

Re: Realtek SoC support in OpenWrt

Hey guys, we just finished another and probably our last hong kong global sources fair. We will try to attend cebit and computex next year instead of global sources.

Re: Realtek SoC support in OpenWrt

Hello!
I have the device D-Link DIR-320 D1 on the basis of the following chips:
1. Realtek RTL8196D
2. Realtek RTL8188ER
3. MXIC MX25L6406E - 64M-BIT [x1/x2] CMOS SERIAL FLASH
4. ESMT M13S2561616A-5T - 200MHz 4M x 16 Bit x 4 Banks Double Data Rate SDRAM
I can not understand the difference between RTL8196D (not found the datasheet) from RTL8196C.
Tell me, is it possible to compile the firmware project OpenWRT under my device?

I have 3x Trendnet TEW-652BRP v3.2R's that I'd love to throw OpenWrt on.

96d is rlx5281 and 96c is rlx4181
rlx5281 is wip right now (we still don't have a reliable toolchain for it)

List out the chips to see if its compatible.

Re: Realtek SoC support in OpenWrt

Hi Roman, thanks for your work on this - I have purchased: TP-LINK TL-WR841HP which seems to be  Realtek RTL8196D and Realtek RTL8192CE - http://wikidevi.com/wiki/TP-LINK_TL-WR841HP. So please keep up posted on your progress and if you have a donate page feel free to share the link.

TP-Link routers are crappy with stock firmware but great when flashed with openwrt firmware -  in my limited experience

Re: Realtek SoC support in OpenWrt

Hey all,

great work Roman (and his collegues) did here!

I tried on an Edimax 3G-6200nL V2 with RTL8196C chipset and RTL8188CE for WIFI. I compiled how roman suggested in the first post. System boots up, but I have a similar problem like kwongwo. I can`t reach the deive via LAN. Pinging on the IP results mostly in "Destination Host Unreachable". Only on startup or if I restart the network a few packets get transmitted with times between 200ms and 2000ms. After that the host is unreachable. The only thing I notice is the flashing LED for the LAN port during ping and the increase of package counters in ifconfig.

In very few cases I also got the skb_over_panic and tried some patches to fix this, but none of it worked, I got this message anyway.

I have no Idea what to do for getting this fixed.

If you want to donate to Roman. He is trying to raise 1000 USD to send his poor Indian assistant to China and Taiwan for face to face interaction with Realtek them selves.
