You can use the wifi driver (rtl8192cd) and network driver (rtl819x) from the 8device in the new kernel. Just need a few modifications...
I'm currently working on the network driver for a DSA version...
The rtw88 from openwrt already have the 8822B 5GHz driver that can work with this project...
Thank you for this appraisal.
This is very interesting. I wish you great success
Sorry for having to ask that, but i'm not very deep into such hardware-related things.
Would it be possible to add the 8devices Komikan to these sources as Dimazhan did for the TOTOLINK A3002RU v1.
It would be a great help to hear the opinion on it
Yes... Its a 97f full mips... The 5Ghz 8822B from the Komikan already have an open driver...
I dont have a board to test, but I can add the config and someone with the board can follow...
I would appreciate that very much. I could provide any informations needed. I think it is also a good chance for me to learn 
Building and testing an image should not be the problem.
awk 'BEGIN{FS="[ \t]+:[ \t]"} /machine/ {print $2}' /proc/cpuinfo

Great... 8devices are openwrt already... their github is in 18.06.
Hello all,
I am new to openwrt and the 819x family.
I have a board based on the 8197FS. The SDK from Realtek is terrible and I'd be happy to switch to a much cleaner base. I'm very happy to find that you worked on this.
Any tip on how to start ? I'm having trouble compiling the ggbruno/master (probably a newbie's mistake somewhere)
Hello gaspare,
FYI I had trouble building from your repository because cvimg was not present. This has been fixed in the repo of dimazhan:
commit 3673300937a729242e0c6775d9022e34410f4e19

Hi,
One question how to make this new image with the kernel vesion 4.14 to run on komikan board
thank you.
Regards
I don't have this board. I upload the image using tftp from boot loader, but the board must have support for tftp (cvimg header)... The image must be adapted in the dts for the board too...
Thanks for your reply, I am now able to use your image, in the komikan board.
I just modified the device tree like this.
&spi0 {
status = "okay";
m25p80@0 {
#address-cells = <1>;
#size-cells = <1>;
#compatible = "jedec,spi-nor";
compatible = "spansion,m25p80", "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <40000000>;
all@0 {
label = "ALL";
reg = <0x0 0x2000000>;
};
partition@0 {
label = "boot";
reg = <0x0 0x20000>;
read-only;
};
partition@20000 {
label = "hwpart";
reg = <0x20000 0x20000>;
};
partition@40000 {
label = "config";
reg = <0x40000 0x40000>;
};
firmware@80000 {
label = "kernel";
reg = <0x80000 0x240000>;
};
partition@240000 {
label = "rootfs";
reg = <0x240000 0x2000000>;
};
};
};
still my kernel is crashing.

I don't see spi-controller driver message in your logs. Did you configure spi driver?
Thanks a lot for your message, by mistake I think I uchecked that, Now I enabled the same, Now I am getting the following message,

Please suggest what I am missign here.
You are tftp-booting an initramfs, isn't it? Question is whether or not your kernel has the relevant configuration for that and whether or not the image is built as such.
Hello. Can someone explain me, how to compile from source? I have a Rtl8197FN and in the menuconfig I can select "Realtek MIPS" but not the specific SoC.
Flash layout in kernel (dts-file) don't correspond to flash layout in firmware image file.
Hi, I am not using initramfs filesystem but squashfs. This has been done by modifying the Makefile of image folder
