Does somebody know who to implement the following solution ?

I can not answer your question, but in the last few weeks there has been a lot of activity on lkml.org regarding the realtek-platform.

Basically „the pro‘s have taken over“ and this is the best thing, that could have happened. I think it is a smart move from realtek to go the „mainline-route“, as it will make their and our lives much easier in the future.

But now we need some patience, because every effort outside of the kernel-development is (IMHO) wasted time.

I can not but agree.

I've tried several kernel branches for now: mainline, next, legacy BPI-SINOVOIP. In the absence of Realtek's support, accessibility to the board features is very poor. Even basic ethernet NIC's are not operational, even with the legacy BPI-SINOVOIP, which is supposed meeting this basic task. I do not even mention the video Mali T820 support, which is probably far from being thought of.

Can you try to dump it from u-boot?

My UART cable hasn't arrived yet, it should has been lost on its way to complete the setback with the W2 itself. Meanwhile I have decided sending the BPI-W2 back to the supplier, as no achievement has been made with the broken ethernet and it looks, that nobody interested from the Sinovoip side. Thus I shall not be able dumping mtd.  The hardware components are good for different applications, but the absence of drivers and kernel support makes it a handicap.

Hi @Igor

 

I have a Banana Pi W3 board which now has kernel code for supporting the two Ethernet ports (actually three, one not wired).

 

    https://github.com/BPI-SINOVOIP/BPI-W2-bsp/tree/rtk1296_ow

 

I am wanting to know if there are any instructions or help available on how to go about :-

 

a) supporting the BPI W2 A53 CPU

b) integrating the Realtech 1296 Support and possibly all th Realtech chipsets, on the following links

 

https://github.com/BPI-SINOVOIP/BPI-W2-bsp/tree/rtk1296_ow/linux-rtk/drivers/soc/realtek

https://github.com/BPI-SINOVOIP/BPI-W2-bsp/tree/rtk1296_ow/linux-rtk/drivers/soc/realtek/rtd129x

 

I am a pretty confident programmer but have not looked at the Linux Kernel properly since v2.4 days and do not know the Armbian framework other than top level image building.

If initial board support package (boot loader + kernel + toolchain) is on some decent level, check those examples:

HW integration and support is very expensive and we can't afford to sponsor maintenance and support more hardware without expanding team / hire people. Maintaining the code is not exactly something people would stay in the line to get that. Development, playing with toys, contributing here and there, existing, but not near enough to cover everything. Nevertheless, there are people that might be interested to join your efforts ... which is the purpose of this forum. Officially, basic conditions are still at least those:

Kernel tinkering experiences are surely helpful but IHMO in this particular case not enough. (I am not dealing with this particular hardware so I could be wrong) Boot loaders are custom pcs of poorly maintained but very important part of the whole - for each board. Also kernel changed in the term how hardware is configured since the old days ...

 

Armbian is "just" a tool that helps you put all those things together. Like Yocto or Buildroot, just from a different perspective.

Okay I understand the background issues now so I have either got to wait till SINOVOIP's drivers get into mainline Linux source (which I dont know if that will ever happen judging on what I have seen), or go about integrating the drivers at my end into Armbian, then testing, possibly getting other BananaPi W2 users testing, and then do pull request to you and maybe to appropriate kernel driver maintainer(s).

 

Is there any documentation on the internals to the Armbian framework at all ?

 

Oh I had done an issue following your guidlines I was pointer at before the forum topics were merged :- https://github.com/armbian/build/issues/2152

Mainlining is a serious business and can easily takes years to complete (but almost no board gets complete support). There are a few companies that provide such services (with help of community) and vendors have to pay hard cash if they choose to go that path. More complicated and exotic device, more work ... Majority can't afford (or would not gamble) and if community around is too small, all you get is old private development kernel drop.

So there is no way to specify an external kernel like the one in the SINOVoIP BPi W2, rather we have to create patch(es) for the Armbian patch directory ?

 

I have checked the mainline kernel, kernel mailing list, and found this maining list http://lists.infradead.org/pipermail/linux-realtek-soc/ its only three months old and it looks like all there is now is boot, and probing support so far.

 

So ot goes down to how long its going to take to wait for support from RealTek or whether I can make up patches from the BPi BSP Kernel code for an Armbian build in the meantime.

Kernels that are not part of the mainline are usually heavily derived from and can contain many incompatible code. Probably it is possible to bring the kernel in and probably somebody already tried that. I would do a wide research before thinking about any coding / porting.

You can see how much it was for past few years. It is probably just you. Like I said - there are other people in community that might want to help out when they see things moving.

OKay I think I will parallel researching further, with preparing patches and either doing a base level diff's without the prepatched code to see what elese there is in the SINOVoIP code, and searching back through the commits if necessary.

I will check whats there against the SINOVoIP code. Not got down to that level yet.

Yeah, I am thinking if I can get the exising BSP Realtek Driver code there and working in Armbian, it will stand as a stop gap until Realtek get there drivers and kernel support there in the Linux Kernel proper.

All I needed was dump from BPI-W2 SPI flash (attached) which I was asking for serveral times here :)

 

In next days, I'll try to boot Linux kernel as described here:

Until now, I thought that dvrboot.exe.bin is SPI image which is supposed to be directly written to SPI FLASH chip.

But today I discovered it is actually a binary which should be executed on the device to program the SPI chip "in system".

We have sources for this binary here:

https://github.com/BPI-SINOVOIP/BPI-W2-bsp/blob/master/u-boot-rtk/examples/flash_writer/dvrmain.c#L2101

so my next step for creating custom SPI with bootloader for my zidoo X8 is to dissect the locations and create a script to assemble SPI image from all the components which could be directly written to SPI FLASH chip.

Hello, I just want to inform to anyone that still is going with this project that from here https://www.terra-master.com/code/ you can download the sources of openwrt for rtd1295 (i believe they are complete, with kernel and bootloader sources, and ffmpeg encoder), i found it because i have a wd nas with this chip, and i was trying to bring the video transcode to linux, i failed because my knowledge is limited, but maybe is useful to bring armbian to this board.

Hello

 

I'm trying to run armbian (or any other custom linux) on my NAS TerraMaster F4-210/2G (SoC Realtek RTD1296 based). It has uart connector (the same connector and pins as Zidoo X9S).

So I've created USB stick with Fat32, put uImage and device tree files into it, created another ext2 partition to use as root. Took uImage from banana-pi-w2 just to check things. And used the following command to load my kernel from uboot (there is no b2ndbc command in my uboot):

Realtek> env set bootargs earlycon=uart8250,mmio32,0x98007800 console=ttyS0,115200 noinitrd root=/dev/sda1 rootfs=vfat
Realtek> usb start && fatload usb 0:1 $kernel_loadaddr uimage && fatload usb 0:1 $fdt_loadaddr tm_f4-210.dtb && env set bootargs earlycon=uart8250,mmio32,0x98007800 console=ttyS0,115200 noinitrd root=/dev/sda2  rootfs=ext2 init=/bin/bash && bootr

[    0.000000] psci: probing for conduit method from DT.

 

After that original kernel loaded instead of mine.

 

Then I tried to use bootm - also without any luck

Realtek> usb start && fatload usb 0:1 $kernel_loadaddr uimage && fatload usb 0:1 $fdt_loadaddr tm_f4-210.dtb && env set bootargs earlycon=uart8250,mmio32,0x98007800 console=ttyS0,115200 noinitrd root=/dev/sda2  rootfs=ext2 init=/bin/bash 
&& bootm $kernel_loadaddr - $fdt_loadaddr
Wrong Image Format for do_booti command
ERROR: can't get kernel image!

 

I didn't find any documentation on bootr command which stays for `bootr   - boot realtek platform`. So my questions are:

is it possible to get info from current stock uboot or devtree or kernel. Or what image type is required by bootm.

 

uboot load log

uboot help

uboot base, bdinfo, flinfo, printenv, showvar, version

 

Also in my device-tree I see the following:

chosen {
        bootargs = "rdinit=/sbin/init  mtdparts=RtkSFC:128k(factory),512k(uboot),320k(logo),1408k(afw),64k(dtb),7680k(kernel),5632k(initrd)  earlycon=uart8250,mmio32,0x98007800 console=ttyS0,115200 loglevel=7";

        cma-region-info = <0x00 0x1000000 0x11000000>;
};

memory {
        device_type = "memory";
        reg = <0x00 0x80000000>;
};

mem_remap {
        compatible = "Realtek,rtk1295-mem_remap";
        #address-cells = <0x01>;

I have the exact same device and it recently started panicking on the btrfs driver after an update to the latest stock firmware and I've been trying to boot a new kernel since then. The source code of the bootloader is included in the source dump released by Terramaster: looking at the code I found a way to boot from USB.

This is the list of commands I use to boot dumps of the stock firmware from a USB stick:

usb start
fatload usb 0:1 ${audio_loadaddr} /dump/mtd3-afw.img
fatload usb 0:1 ${kernel_loadaddr} /dump/mtd5-kernel.img
fatload usb 0:1 ${fdt_loadaddr} /dump/mtd4-dtb.img
fatload usb 0:1 ${rootfs_loadaddr} /dump/mtd6-initrd.img
setenv bootargs rdinit=/sbin/init mtdparts=RtkSFC:128k(factory),512k(uboot),320k(logo),1408k(afw),64k(dtb),7680k(kernel),5632k(initrd)  earlycon=uart8250,mmio32,0x98007800 console=ttyS0,115200 loglevel=7 root=/dev/ram0 initrd=${rootfs_loadaddr},0x${filesize}
go all

 

From a comparison of the decompiled stock dtbs, the hardware looks very similar (if not identical) to the Synology DS418 and I was able to boot to a shell with a custom 5.9 kernel (and dtb) built from https://github.com/afaerber/linux/tree/rtd1295-next and a ramdisk built with the latest stable buildroot.

The bad news is that currently nothing else works. This is the dmesg I get:

Something is causing the gpio driver initialisation to fail and therefore also the pcie, sata and usb drivers cannot start. I'm suspecting an issue with the pin mux configuration but this is my first deep dive into the arm kernel so I'm not 100% sure how to approach this roadblock.

Any suggestion is very welcome.
