interesting factoid; it appears that A20 dropped the PATA controller. Instead, it put EMAC pinmux on PH mux2. e.g. 100mbit + gbit is possible in a dual setup

right, back to hacking ;)

also i successfully built xbmc for a20 with the new sources and blob - but no test at all. first build a kernel with new cedar_dev. atm there is compilation running for xbmc for a10... let's see how well the new blobs work :p

on my latest test, in the sun7i_deconfig, CONFIG_SUNXI_EMAC=m could it a good idea to change it to y instead of m, isn't it ?
<rellla>
ok. sun7i_cedar and sunxi_mem are (almost) complete identical in 3.3-cb2 and 3.4
<popolon>
in emac_readme.txt : 2) using cpu to read/write fifo, not dma

I didn't added this detail in the linux building tuto
<popolon>
need to add it in the case of device with ethernet port

bfree: 3.4 already has soc-detection code, so we CAN improve it to the point of supporting multi-sunxi sun[4567]i in a single bin

but not there yet

such refactoring/cleanup also helps 3.10 and then mainline

Hi everyone. Have anyone tried using USB OTG on Cubieboard2 with sunxi kernel? I am interested in accessing data throught mass storage backend.
<popolon>
too sad, on cpu : allwinner A10, A13, 31, 31s, but not A20 :(
<EGM>
I am sorry, is that related to my question, or are you explaining your trouble?
<popolon>
not at all
<popolon>
:)
<popolon>
I understand your question
<popolon>
do you mean: plug the cubieboard on a computer
<popolon>
and read cubieboard data from the computer ?
<EGM>
Well, not exactly.
<popolon>
using mass storage
<popolon>
else there are 2 standard USB ports
<EGM>
I need to be able to switch some kind of storage between linux system and USB OTG mode, so it can be written in linux, and then read as mass storage from Windows.
<EGM>
I know that Cubieboard2 has OTG port (miniUSB), but I have no idea if there is support for that in sunxi kernel.
<popolon>
any external USB HDD is seen as mass storage
<EGM>
I am sorry, but I believe no do not understand my question.
<popolon>
what should be mass storage ?
<popolon>
the HDD/usb key/...
<popolon>
or the cubieboard ?
<EGM>
The Cubieboard should act as mass storage.
<popolon>
aah ok
<popolon>
and have a HDD pluged in
<popolon>
(or something like that
<EGM>
No, no HDD. Just create filesystem in file on NAND or SD card, and mount it in linux, so I can save some files there.
<popolon>
ok
<EGM>
After that, unmount it from linux and connect it as mass storage using OTG port to computer.
<popolon>
so you should not umount it
<popolon>
but instead, share it as mass storage ?
<EGM>
Well, I believe that there is kernel module that takes file as image and exports it as USB mass storage via OTG port.
<popolon>
Or could be possible to share it mounted/ unmounted depending on software
<ykchavan>
EGM, I do this all the time on default installed android.
<ykchavan>
I do not think there will be any problem doing with sunxi kernel.
rz2k has joined #linux-sunxi
<EGM>
Yeah, I know that it works on android, so I suppose that it's hardware support needed. But I would like to do it in linux.
<EGM>
Unfortunately, I have not found any good sources explaining how to do that...
<ykchavan>
I see. Let me try on my cubieboard.
<EGM>
IIRC, when I tried to load module called file_storage (or mass_storage, I believe that both should do basically the same), I got some error which did not help me at all.
<Turl>
EGM: you just need to load the gadget module
<Turl>
then echo the file path of your block device to the lun file on /sys
<EGM>
Turl: I believe that I need monitor and mouse/keyboard for using that android image, right? Seems like there is no shell on serial port...
<Turl>
you can use ADB shell via the usb otg port :)
<partoa>
Can anyone help with that? We suspect that it may have something to do with the PMU and clock...given that we are presently not able to read the Boot1 file header and therefore can't get a custom uBoot created for our board.
_BJFreeman has joined #linux-sunxi
<EGM>
Turl: Well, I dont have android sdk installed. I will look into that tomorrow probably.
<EGM>
In fact, only thing I need to know today is if it is possible to use USB mass storage gadget via OTG port.
<Turl>
partoa: panic=rw? did you actually write that?
_BJFreeman is now known as BJfreeman
<Turl>
partoa: otherwise your ram is corrupting random bits
<partoa>
Nope....PengPod image...
<partoa>
Those were the only images that we found that were able to boot.
<Turl>
partoa: you have 1G of ram on the device right?
<partoa>
Yes, 1G
<Turl>
as 2x512?
<partoa>
No, 4X256
<Turl>
hmm
<Turl>
hno: ^ is that supported? any board using that?

partoa: I'm not too familiar with the memory controller, but hno or oliv3r might be able to help
<partoa>
Turl: Thanks...lets hope hno: or oliv3r: pick up on this :-)

hey, can I get some help with setting up nand-boot on CB1?
<cubear>
seems like the bootloader is rather disobedient
<oliv3r>
Turl i think there's even 4x 128M; i think my tablet does that
<cubear>
I've used nand-part to setup 2 partitions - nanda and nandb. nandb is the rootfs
<cubear>
I've been told to put the uImage, script.bin and uEnv.txt to the nanda partition root folder
<cubear>
but the bootloader fails to load them
<cubear>
I can load them manually and it boots fine
<cubear>
the bootloader tries to load linux/uImage and linux/env.txt files
<cubear>
I can't modify the bootloader commands because it doesn't support the "saveenv" command
<cubear>
naither I can put uImage and other files into the linux folder because they... magically disappear :-/
<cubear>
any ideas?
<partoa>
oliv3r: any idea what is happening with out boot process?
<cubear>
I'm sure I copied uImage into that folder too
<partoa>
Has anyone had any problem reading the boot1 file header getting "libusb usb_bulk_read error -7" as an error message after running "./fel read 0x42400000 0x82d0 boot1.header "
<partoa>
A grep on both fel and libusb-1.0 for "usb_bulk_read" does not turn anything up...
<oliv3r>
then do dd if=cubie1.bin of=/dev/sdcard bs=8 seek=1024
<cubear>
oliv3r, I'm doing a nand install
<cubear>
sdcard boots fine
<oliv3r>
but we don't have u-boot support for nand
<oliv3r>
ohh, your doing something unsupported
<oliv3r>
who was asking for 4 memory chip enabeld u-boot?
<oliv3r>
hmm, your fatls look odd
<cubear>
oliv3r, patwood said "The second thing you'll need is a u-boot that can load the uImage from nand. You can find one here: http://dl.miniand.com/patwood/u-boot.bin Put it in the /linux directory on the vfat partition."
<oliv3r>
oh thats the directory named 'linux'
<cubear>
so that's what I used
<oliv3r>
ah ok
<cubear>
I manually loaded the uImage
<oliv3r>
well normally, whatever is preinstalled in nanda is what you want
<steev>
u-boot probably has ENV_IS_NOWHERE defined somewhere
<cubear>
it looks for an uImage inside the linux folder
<oliv3r>
nand enabled u-boot is VERY limited
<oliv3r>
it's an extremly old hacked up u-boot
<oliv3r>
but you can manually change your env
<cubear>
where?
<oliv3r>
extract the env partition
<oliv3r>
convert it to txt, edit it, compile it to bin, dd it back
<cubear>
that's an option yes
<steev>
wow, that IS hacky
<oliv3r>
steev: you onyl change the env once, its' allowed to be hacky: )
<cubear>
where is this "env" partition? I assume it's at an address before the first nanda vfat partition
<oliv3r>
nandb or nandc
<oliv3r>
don't recall
<oliv3r>
i think b
<cubear>
I formatted the nand with nand-part, so there's only 2 partitions now - nanda and nandb. nandb is the rootfs
<cubear>
anyway I think I've found the bootloader command
<cubear>
seems to be hardcoded inside the u-boot.bin file I downloaded earlier

partoa, you can easily create a custom u-boot SPL. The dance about reading boot1 is only when not knowing the proper parameters like suitable DRAM clock etc and most people are not good at guessing these right..
<partoa>
Ahh...
<partoa>
I'd place us at among the people who are not too good...I have seen that the mele a1000 uses the same IC as us, what are the odds that their DRAM clock has the same frequency as ours?
<cubear>
I think I bricked it, now even using the original u-boot.bin doesn't run
<cubear>

<hno>
And PMU, CPU clock and DRAM clock are all closely related.
<cubear>
okay... can anyone explain to me why do the files I copy over to /dev/nanda disappear over reboot?
<partoa>
hno; would it still be unstable if it always fails the moment the PMU "comes into play"?...I ask because we were finding it rather consistent that we even imagined that the PMU could be faulty.
<Turl>
cubear: /dev/nanda is a block device
<partoa>
hno; do you have a DRAM clock range that we can try play with? Say a minimum and maximum.
<cubear>
Turl, could you elaborate?
<Turl>
cubear: you need to mount it somewhere and then copy files
<Turl>
mount -t vfat /dev/nanda /mnt, copy your stuff to /mnt; sync; unmount /mnt
<Turl>
then try mounting it again, your file should be there
<cubear>
Turl, can I assume that sync gets called automatically upon unmount?
<cubear>
nope, they vanished again
<cubear>
alright, I mounted, copied, sync, unmounted
<cubear>
then I remounted and the files are all there
<cubear>
now let's reboot again (from sd-card)
<cubear>
nope, they're all gone

<oliv3r>
hno: hi!
<hno>
hi oliv3r
<oliv3r>
hno: i've pushed cubietruck support to u-boot (limited to 1GB)
<oliv3r>
and i've pushed to my personal github a 2GB enabled branch
<oliv3r>
since u-boot doesn't (properly) support 2GB
<hno>
What is the problem wit 2G?
<oliv3r>
i think it 'works' most of the time, phys_size_t is typedefed as a unsigned long
<oliv3r>
pyhs_size_t is used for ram_size that is passed onto the linux kernel
<oliv3r>
afaik
<partoa>
hno, we actually have established that we can't do much debugging without using building our u boot SPL. We'll just have to work out the collect clock setting.
<hno>
unsigned long is fine for 2G.
<oliv3r>
however, get_ram_size is retunring a long (signed)
Black_Horseman has joined #linux-sunxi
Black_Horseman has quit [Changing host]

and we everbody does (inc sunxi) gd->ram_size = get_ram_size(base, size);
<oliv3r>
parameters are (signed) long; return is (signed) long
<hno>
oliv3r, ok, that would be a bit of a problem.
<partoa>
Thanks a lot. hno, Turl. I will be sure to blog or contribute in some way as soon as we get a solution.
<oliv3r>
so representation goes a little bad; but cramming that (negative) number into the phys_size_t kinda works
<oliv3r>
hno: check out the patches on my github branch; i did bring the issue up on the u-boot ML; but it got ignored
<hno>
but do get_ram_size actually test the 2GB when size < 0?
<oliv3r>
so far :p
<oliv3r>
i doubt it, how can you ever have a negative ram size
<oliv3r>
i guess, the function was written with 32bit in mind, but completly ignoring the fact that a SoC could do 2 GiB's
<atsampson>
I feel like I've got a negative RAM size some mornings before I've had my first cup of tea...
<oliv3r>
anyway I think i properly fixed it, and i can merge it over; once I receive your blessing ;)
<hno>
There is several that do 2G today, so can't be alone in this problem.
<oliv3r>
well i noticed it because the SPL reported a negative memory size, u-boot did report it properly (because it does ramsize >> 20 to print)
<oliv3r>
and I think the negatie sign drops?
<hno>
ARM spec even supports PAE with huge amounts of RAM even in 32-bit.
<hno>
>> sign extends, so it must have been unsigned at that time.
<oliv3r>
well I think i prpoperly fixed it
