Trying to bring the Firefly up on mainline(ish)

Hi,


I've been trying to get the firefly to boot up with something as close

as possible to current mainline.


The best results I've had are with the devel/workbench branch of

https://github.com/mmind/linux-rockchip.git


This is currently based on 3.18-rc1 with various Rockchip patches.


There do seem to be a few stumbling blocks.


1) No firefly device tree files (the ones in the SDK don't work here).

Though the rk3288-r89 device tree seems to do a fairly good job.


2) rknandbase.c

I've had to pull this from arch/arm/mach-rockchip in the SDK to the

above kernel tree. It builds OK.


However I don't think it initialises properly due to there being no nand

stuff in the device tree. So we get these messages


rknandbase v1.0 2014-03-31
rknand_driver:ret = 0

While with a kernel built from the SDK we get these


rknandbase v1.0 2014-03-31
rknand_probe clk rate = 148500000
rknand_driver:ret = 0


And then we get stuck in the dw_mmc driver


Synopsys Designware Multimedia Card Interface Driver
dwmmc_rockchip ff0c0000.dwmmc: Using internal DMA controller.
dwmmc_rockchip ff0c0000.dwmmc: Version ID is 270a
dwmmc_rockchip ff0c0000.dwmmc: DW MMC controller at irq 64, 32 bit host data width, 256 deep fifo
platform ff0c0000.dwmmc: Driver dwmmc_rockchip requests probe deferral
ff100000.saradc supply vref not found, using dummy regulator
TCP: cubic registered
NET: Registered protocol family 17

sdmmc-supply: 3300 mV

dwmmc_rockchip ff0c0000.dwmmc: Using internal DMA controller.
dwmmc_rockchip ff0c0000.dwmmc: Version ID is 270a
dwmmc_rockchip ff0c0000.dwmmc: DW MMC controller at irq 64, 32 bit host data width, 256 deep fifo

And get no further.


Is rknandbase still the right thing to use or should we be using some

other upstream NAND driver?


If you have any advice on another kernel tree to try or patches to try?


I'll attach the .config and device tree I'm using and also the boot messages.


I do see a lot of Rockchip stuff making its way upstream and 3.19 looks like

it will be a better foundation to work on. But how much Firefly specific stuff is

also needed?


OK, so I can't seem to attach any files as it keeps telling the extension is

not allowed.


I'll just have to put them inline below....


Cheers,

Andrew

There're lots of differences between firefly-rk3288.dts in SDK and rk3288-r89.dts,

especially in the PMU, which may be the reason of the frozen system.




Also are there lots of code differences between the SDK kernel and mainline kernel.

The mutuarity of rk3288 support in mainline kernel needs time and effort.

We're going to give away some boards to the core kernel developers, in hope of fastening the pace.

Wow, what a large post...




It is difficult to follow if the various sources and files aren't placed where they should be...

To get your firefly booting mainline, you should create a github account, fork or mirror the required sources (from mmind) and then collect your additional files and push them in your account. When you have questions about certain things, put a link or copy only a few lines of doubtful code and a link to the rest. In this way people could use the full feature set of git and github to check, compare, improve your code.

To the nand:

There is no and there will probably never be an open source driver for nand. You can use the rknand.ko together with a matching version of the RKxxx Loader.img is a bootloader. But the nand handling and FTL handling is licensed software that is not available as open source.

the rknand driver available as open source is a minimal interface to access the SOCs NAND hardware interface. You can try to access the chip and try your own FTL or NAND aware filesystem on top of it. That would probably require to write a low level MTD interface set of functions.

For the DTB and config files:?

I am waiting if I can get a RK3288 based system. I do not have any for now. If that changes there I will be putting together a dtb as one of the first actions. We could share our results over github.

And for mainline, I had some other priorities in the last weeks, but I'll fetch mmin00s changes soon and add a collection of dtb and config files. The way the linux kernel is developed has changed a bit and so it is required to do some more tricks and treats to have the reuired latest linux-next chnages mirrored in your github account. But how I told above: Attach yourself to one of the guru's gits and try to rebase often.?

Best regards

It wouldn't let me attach files.

Yep, that's the tree I'm using.

Hmm, so what is
https://bitbucket.org/T-Firefly/firefly ... ?at=master





Admittedly it looks a little lacking to be a full driver. So if it's not the full driver, where does the full driver live?

I can build and boot kernels from the Firefly SDK and didn't do anything with a rknand.ko




> I am waiting if I can get a RK3288 based system. I do not have any fornow. If that changes there I will be putting together a dtb as one ofthe first actions. We could share our results over github




Or even post it to the linux-rockchip mailing list to get it upstreamed. I do use GitHub, but hesitant to just create even more forked repositories that just muddies the waters and I'm weary of things just languishing in random repositories.




mmind recommended to use his rk3288-r89.dtb and it did seem to help somewhat.




Cheers,

Andrew

This driver there is a small piece of software just opening the door to the NAND controller interface in the SOC.

To have a real NAND driver you need a FTL (flash translation layer) and ECC handler. The ECC handler detects and corrects (multi-)bit errors, while the FTL maps blocks at a logical position to a physical block. Around that is a wear leveling driver that counts block writes of the large erase blocks and spreads writes to the smaller write sectors in a manor that avoids wear-out of single sectors.

This is a complicate job and so there is only commercial software available to manage that job.

The source code of the real rknand driver is only availble to some RK people and is not given out of hand even you sign an NDA.




So if you like to use the NAND you need to use the rknand.ko driver as that binary image that it is. The partitions are created in the parameter file.




With RK3288 some things may have changed. But AFAIK the uboot available for RK3288 can use the same NAND code as a binary blob that is used by the Loader. So even with RK3288 NAND access will only run through binary only rknand.ko.

If you like to have very fast static memory, use dwmmc driver and a fast SD card like Samsung Extreme Pro 45/45 or Sandisc Extreme 40/45 (write/read speed in MB/s)

The RK3288 features additional transfer speeds but I am not sure if this is already implemented in mainline. Then you can use XDHC cards up to 100/100 if the hardware layout and termination has been trimmed to the last value. eMMC memory can be accessed with 200/200 (cause 8bit width).

However this needs additional software in the SD/MMC driver section. Using raw NAND is always a bad idea.

Thanks for the info. Still a bit confused though.

I've just booted a kernel built from the Firefly SDK. It's booted from
NAND with the root fs also in NAND.

I don't see any sign of rknand.ko
The name makes it look like a kernel module. But where is it?

# lsmod
Module????????????????? Size? Used by
#

Cheers,
Andrew

So I just checked the initramfs image I'm using to see
if it was somehow in there and then somehow not actually
being loaded after boot. But no, no sign of it.


I can only surmise that the rknand driver isn't actually needed.
Indeed I don't have any /dev/mtd* devices. I do have
/dev/block/mtd/by-name/ which contains links to /dev/mmc*

So I guess I'm bypassing some NAND layer and just accessing
the NAND as a MMC device?

Cheers,
Andrew

Hmm, from
http://wiki.t-firefly.com/index.php/Fir ... _Initramfs

we have this sentence
"The development board use eMMC flash. There is no need of
special kernel module file."

So maybe this is referring to rknand.ko and so does indeed infer
that rknand.ko is not required on the firefly?.

Cheers,
Andrew

All these Linux guys, having same problems here in Android.  Need some source codes to work on kernel at home (dtb, dtsi,boot and etc.)  Seems the only kernel I can get running is from the R89.  Any one have a source code for the RK3288 which isn't the Chrome.
