Any plans for Realtek SOC support?

drbrains · June 17, 2018, 6:37am

I know the older Realtek SoCs where sort of crippled without full MIPS but using the Lexra core.

The RLT8197F(B) is full MIPS. I saw some other efforts to port Realtek to OpenWRT/Lede. Any plans to officially support Realtek?

Reason I ask is cause I just got challenged to run something open source on a “360” (chinese brand) router which has the 8197FB as basis. The specs look good especially for the price they are selling the devices. Older 360 models were MT7628 based, their latest model had a 1GHz Realtek SoC.

Link to the device ?
Maybe I need more things to play with ...

drbrains · June 17, 2018, 3:47pm

It seems they are only selling it inside China at the moment. I couldn't find any on the international sites from JD.com, Aliexpress etc.

(Chinese link to JD: https://item.jd.com/25354811810.html )

The sales rep. gave me an (net core) "360" P4. Realtek RTL8197FB 1Ghz CPU and 2.4Ghz wifi, RTL8812BRH 5 Ghz and RTL8367RB ethernet.

@ElektromAn, you have my email, if you're interested let me know. I'm sure I can ship one to you.

Is there somewere GPL sourcecode for it? The challenge is to port recent kernels and rewrite/port realtek drivers. Can you share bootlog?

ElektromAn · June 19, 2018, 3:45pm

RTL8197F?

is some interesting SoC
Looking at wikidevi there are already ~10 devices on sale, mostly from the cheap low cost side.
Anyway sources based on OpenWrt for v3.10 kernel

look for rtkmipsel target
I think almost all drivers are there
It should be feasible to use this as a starter

xssa · June 19, 2018, 8:27pm

Where is openwrt_rtk with 3.10 kernel and where is recent openwrt with 4.14 kernel? Did you have time to look inside proprietary realtek driver's codebase? It is nearly impossible to port it onto recent linux kernels. @hackpascal did great work to port LEDE onto Realtek SoC but gave up. It is interesting to hear his point of view.

ElektromAn · June 20, 2018, 7:46pm

RTL8107F != RTL8196C
The latter one misses some patented functions, so it's/was a waste of time.

@xssa
Please follow the link I gave here
There is the sdk for rtk
And some defconfigs

xssa · June 20, 2018, 8:42pm

RTL8107F != RTL8196C

@ElektromAn What is in difference?
You misunderstand me probably. I'm not about cpu core or it's architecture, but about drivers. They are written on plain C and have nothing to deal with Lexra or clean MIPS32 (and will run on both if compiled with right toolchain) but code itself is awful and is far from recent linux kernel standarts, thus has to be rewritten from scratch. Do you have needed datasheets for this SoCs, and knowledge, and time to perform this piece of hard work? IMO Realtek itself has to invest their efforts to be supported well in recent Linux kernels.
And about Realtek openwrt-RSDK - I know well what is inside it.

ElektromAn · July 3, 2018, 3:59pm

The code on openwrt-rtk
rtk_openwrt_sdk/target/linux/rtkmipsel/
is ugly, awful, whatever
They messed up the old lexra and new MIPS code.
Also some registers are not well named
i.e.for GPIO, pinmux, clok

And I have no datasheet at all.

xssa · July 7, 2018, 9:56pm

@ElektromAn, here you can find some useful datasheets, and, again, @hackpascal already did big piece of porting work and indeed have knowledge to do the rest.

ElektromAn · July 13, 2018, 7:32pm

@xssa
The datasheets are for the older 9187D.
But I think parts of this may be the same for 9187F.

For initial support aka boot this is maybe sufficient.
Hmmm

Hi All!

I have a D-Link DIR-842, and play with this device.
I have some information:

Realtek is a dead end for OpenWrt. You can only blame them for that. Don't buy hardware with their SoCs if OpenWrt support is what you're after.

Hi All!

The UPVEL ur825ac Barrier Breaker OpenWrt firmware (Upvel_OWRT_v0.1.2build39.bin) work on D-Link DIR-842 B1.

You can download more firmwares from:

I changed D-Link boot loader first.
I used CH341A spi flash programmer.

Here is the dmesg:

The RTL819x LEDE without Wifi compiled already.

You can find bootloader with Winbond W25Q128 support:

Hi All!

The dmesg output contains the IDs of Wifi PCIe devices:

[ 24.880000] Find Port=0 Device:Vender ID=818b10ec

That is neither OpenWrt nor is a five-year-old OS suitable for any use, due to multiple, well-known, actively exploited vulnerabilities in the kernel, third-party applications, and 802.11 protocols.

cassy · November 5, 2019, 9:18pm

Hi All!

I would use the original and newer OpenWrt.
If they exist, but not. Nothing.

The Barrier Breaker is more secured like brand routerOS.
I think: All brand (blackbox/closed) routerOS have factory backdoor:)))))

The RTL819x for LEDE from hackpascal compiled already.
I didn' try load mainline kernel wifi modules yet.
The finished "rootfs" is still too big.
I must configure required/needed modules, and packages.
When done, i will try upload to the router, and try load mainline wifi modules.

The Realtek SOC's (rtl8881a, rtl8196e, rtl819xd) DOESN'T CRIPLED MIPS!!!!!!!!!!!

cassy · December 17, 2019, 10:38am

Hi All!

I checked the code of realtek SDK 2.5 and I found something very important.
The forums and openwrt informations contains:
"Realtek inherited a reduced mips ISA via Lexra"
Realtek SOC's have lexra core with reduced (crippled) mips funcionality.
The lexra core doesn't support four unaligned instructions:

" It was founded in 1997 and began developing and licensing semiconductor intellectual property cores that implemented the MIPS I architecture, except for the four unaligned load and store (lwl, lwr, swl, swr) instructions. "

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

BUT

The Realtek SOC's (rtl8881a, rtl8196e, rtl819xd) support these four unaligned load and store opcodes (lwl, lwr, swl, swr) !

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Conclusion:
The Realtek SOC's (rtl8881a, rtl8196e, rtl819xd)are full MIPS. The instruction set is the same as the mips r3000 and not the r6000.

The MIPS R6000 doesn't support unaligned instruction opcodes.

There is a guy who ported RTL8186 in linux kernel and successfully able to boot it https://github.com/yashac3/linux-rtl8186 . RTL8186 doesn't support unaligned load and store opcodes (lwl, lwr, swl, swr). But RTL8196E does as u say and I have a RTL8196E device. I followed his steps like 1 year ago and try to do a port for my 8196E but it didn't worked, back then I didn't know that 8196E is a full MIPS. Do u want to check his port and continue ?
