<mnemoc>
for me curl -I always returned the same :|
<vpeter>
I see same image in browser. And with curl.
<NiteHawk>
mnemoc: seems fixed now, at least for the "full size" image from the above urls
<NiteHawk>
some of the intermediate sizes / thumbnails still have the reddish background (improper white balance), but that may be due to my browser cache - will check that
<NiteHawk>
i purged it and got the right thumbnail, but it's back to the previous state on the file page - guess that's more CF caching. however, that's a minor problem as it doesn't affect any page display directly

NiteHawk: I can't open the page from here. but if you give me the url of the image I can invalidate it on CF
<libv>
the original has a watermark that undoubtedly says "confidential"
<rgwan>
I has been asked the foresee FAE
<rgwan>
and foresee FAE give me this image
<rgwan>
so I put it on this website
<rgwan>
so I wired a eMMC on it
<rgwan>
and bottom are picture
<libv>
rgwan: what does "I has been asked the foresee FAE" mean?
<rgwan>
In fact, I once meet a chip named "NCTSTS86-04G"
<rgwan>
used in Mele A100 Dual Core version
<libv>
rgwan: this picture does not seem to be creative commons.
<rgwan>
I'm sorry...
<libv>
rgwan: i will have no option but to remove this
<rgwan>
Yeah, but you can save this pinout
<rgwan>
and I 'm curious about this chip. So I make a search.
<libv>
rgwan: save what pinout?
<rgwan>
the tSD's pinout

rgwan: i suggest that you spend some time with inkscape and draw your own image.
<libv>
s/image/picture/
<rgwan>
yeah
<RSpliet>
but regarding your earlier problem: I'd first try to use the eMMC in Linux while booting from a regular MMC image before trying to format it in such a way that the bootloaders are on there
<libv>
rgwan: do you have a local copy of this picture, so that you can recreate the information?
<rgwan>
Yes, I have
<rgwan>
With Mele i7 disassembled, I discovered that the NAND solder handler has the same pinout as tSD has.
<rgwan>
So I wired a eMMC on it
<rgwan>
It can be recgonize
<libv>
rgwan: ok, then i will delete this picture from our wiki now
<rgwan>
OK
<RSpliet>
rgwan: well, if this means you wired the eMMC pins to the NAND controller it's not going to work
<rgwan>
no
<rgwan>
I wired it to the SD2 controller
<RSpliet>
they share the same pins on the SoC
<rgwan>
and the eMMC can be operate in the SD Linux system
<RSpliet>
ok, so that bit works
<sawtooth7>
oh this 48-TSOP has SD only pinouts ? interested
<rgwan>
not "only"
<rgwan>
it has both of it
<sawtooth7>
it's the first time i see this
<rgwan>
Flash and SD
<sawtooth7>
i thought they were all NAND flashes
<rgwan>
But it can't boot
<rgwan>
because A31 has a bootselect pin
<RSpliet>
rgwan: usually BROM tries various controllers
<rgwan>
uses this two pins to select startup device:eMMC/SD NAND flash or SPI Flash
<sawtooth7>
right
<rgwan>
It isn't like A10/A20/A13 devices
<RSpliet>
ok, then I can't help you further
<rgwan>
s/isn't/doesn't/g
<rgwan>
So I'm trying to find out where this the two pins hide...
<sawtooth7>
oh wait, but it's not like the SD has this TSOP-48 package
<RSpliet>
no, "isn't" seems more correct in this context
<rgwan>
Now I haven't any information about it
<rgwan>
so I ask it on this group
<sawtooth7>
there is another footprint inside the TSOP-48
<rgwan>
sawtooth7:yeah
<rgwan>
The TSOP-48 pinout can support two type of flash:tSD and raw Flash
<rgwan>
libv:I remember that the cubietech's cubietruck has a tSD on it
<rgwan>
it can supports tSD
<libv>
rgwan: is there anything similar on olimex devices?
<libv>
but cubie is a20
<rgwan>
I don't know olimex devices
<rgwan>
cubie has the same design on it
<rgwan>
The Mele A100 Dual core version also has same design on it
<rgwan>
but basically, their are A10/A20 device
<rgwan>
so they don't suffer from BootSelect bother
<libv>
rgwan: why do i mention olimex: it is oshw, so you have full schematics and everything

Hi NiteHawk , i managed to get /proc/device-tree , i was lacking a option in kernel config
<Dodger78>
BUT , im lacking the /sys/ cpufreqd entry
<KRiSh5>
dear channel members, is there anybody with knowledge of the Goodix GT911 drivers here ?
<NiteHawk>
hi Dodger78! well, some progress for a start :) what was missing for /proc/device-tree (in case someone encounters that again)?
<Dodger78>
its a new option for 4.1 kernels. you need to activate Device Drivers -> Device Tree and Open Firmware Support -> Device Tree overlays
<Dodger78>
CONFIG_OF_OVERLAY
khuey|away is now known as khuey
<Dodger78>
another option makes me guess it might be SYSFS ...
<NiteHawk>
i see. do you have a /proc/device-tree/cpus/cpu@0 now?
<Dodger78>
its called "Generic Dynamic Voltage and Frequency Scaling support " DVFS
<Dodger78>
yes i got it , but no cpufreq in it as far as i can see
<NiteHawk>
that won't be in there. but does it list stuff like "operating-points" and "cooling-[max|min]-level"?
<Dodger78>
uh i ge some weird chars upon cat operating-points
<Dodger78>
im on the target via ssh
<NiteHawk>
same here. i just wanted to make sure that node is there at all ;)
<Dodger78>
^^
<Dodger78>
dmesg still says something about missing clock-frequency property , but that might be normal
<KRiSh5>
does anybody knows if there is an implementation of the Goodix GT911 drivers which does not use HotKnot ? Also it would be very helpful if somebody has a sample code to initialize the touch panel with that chip and send configuration of registers.
<NiteHawk>
Dodger78: yes, i have those messages too
<Dodger78>
shall i try CONFIG_PM_DEVFREQ ?
iamfrankenstein has joined #linux-sunxi
<Dodger78>
it mentions something about cpufreqd in its comments
<NiteHawk>
for now it looks like you have the required device (tree) nodes in place. it's still not clear to my why you get no cpufreq in /sys
BroderTuck has joined #linux-sunxi
<NiteHawk>
maybe try CONFIG_CPU_FREQ_STAT_DETAILS? i'm doing fine here on A20 with # CONFIG_PM_DEVFREQ is not set
<Turl>
see if you have CONFIG_CPUFREQ_DT enabled
<Dodger78>
ok i give it a shot ..@Turl yes i have
awe00 has quit [Ping timeout: 264 seconds]

Dodger78: and nothing mentioning cpufreq in /sys/devices/system/cpu/ and deeper?
<Dodger78>
@Turl no
<Dodger78>
@Turl im at 4.1 hansg latest kernel
<NiteHawk>
errr... did you actually enable CONFIG_CPU_FREQ_STAT at all?
<NiteHawk>
i'm not sure we checked that one yesterday

<Dodger78>
nope except the missing frequency-property
<Dodger78>
and some pinctl usb ahci stuff

yes, those messages are common - we should consider them "normal" for now

to be honest if have no idea how you can have CONFIG_CPU_FREQ and CONFIG_CPUFREQ_DT set, and with the operating points seemingly present, still fail to get any /sys/devices/system/cpu/cpu?/cpufreq :/
<Dodger78>
CONFIG_SYSFS_DEPRECATED ?
<NiteHawk>
again not set in my .config ...
<Dodger78>
older kernels have something like CONFIG_PROC_DEVICETREE which my version is lacking
<NiteHawk>
and as you said: you got your /proc/device-tree now

NiteHawk: is there any way to use nand from mainline u-boot and linux?
<alexxy>
on cubietruck
<wens>
work in progress
<NiteHawk>
i'm not sure. u-boot recently received some improvements on NAND, but a full SPL-boot still doesn't work. mainline linux is also only slowly catching up on nand support iirc
<NiteHawk>
"work in progress" sums it up pretty much
<alexxy>
also any ideas why dmesg on 4.1 kernel full of

does it works somehow on a20 (cubietruck)

Anyone with a github account who can reopen https://github.com/allwinner-zh/bootloader/issues/4 ? While it's good that they release the nand (kernel and uboot) source, it's no good if most of the files contain "All rights reserved"...

A quick check shows that while they relisenced the A20 stuff under GPL, everything released later has used more or less the same licensing that the A20 stuff had before GPL-ing. The commitlog usually refers to opensource, so it should be possible to get them to do the right thing.
