Is it possible to use UART0 when linux run from SD?
<wingrime>
yes
<wingrime>
UART0 are different device
<wingrime>
on different pins
<vinifm>
in a13
<wingrime>
yes
<wingrime>
I have a13 and tested this\
<vinifm>
are you aware of the conflict between SD and UART0?
<wingrime>
vinfm: on;y if you not reconfiguread sdcard as uart
<wingrime>
otherwice there is no problem
<wingrime>
UART are simple debug interface
<vinifm>
which pins you used to UART0?
<mripard_>
uart0 isn't available on the A13
<mripard_>
only uart1 and 3
<vinifm>
because is there a conflict between SD and UART0?
<wingrime>
vnifm: uart0 present in HW
<vinifm>
they share the same pins
<wingrime>
*not persent on a10
<wingrime>
sorry
<wingrime>
I mean
<wingrime>
a10 have 0,1,2,3 uats
<wingrime>
13 have 1,3 uarts
<vinifm>
hum
<wingrime>
it useless try use that not presnt in hw
<vinifm>
but in a13-olinuxino uart3 is busy :(
<wingrime>
debug - gps - gps - bluetooth (for a10) meaning
<wingrime>
vingm what wrong with uart1 ?
<vinifm>
it is to console
<vinifm>
0:
<wingrime>
so what do you want ?
<wingrime>
uart0 simply not-exists on a13
<vinifm>
but: <hno> You can boot from SD and then use UART0 if you like.
<wingrime>
you can not use 0: as console
<vinifm>
<hno> vinifm, you can't use mmc0 enable if you want to use uart0. You need to load everything you need from the SD into RAM, then let it switch to UART0.
<wingrime>
you can try use usb gadget as consiole
<wingrime>
vinifm: you can simply place root on nand or someelse may be usb flash
<vinifm>
really, I'll try
<vinifm>
to usb, console=?
<wingrime>
don't tryed just teory , you need setup console gadget in menuconfig
<wingrime>
but I loaded console gadget as module and get console
<wingrime>
it little difficuld add that stuff to menuconfig
<vinifm>
do you use OTG?
tinti has joined #linux-sunxi
<wingrime>
vinfm: as host
sanka has joined #linux-sunxi
<wingrime>
vinfm: I just tested and fixed
<vinifm>
do you use OTG or HOST?
<wingrime>
host only
<wingrime>
I have tablet
<wingrime>
so I do it for keyboard and mouse

hi, we've got an A10s device on which we've installed ClockworkMod Recovery which we unluckily can't control due to the lack of hardware buttons. We've got some help in #cyanogenmod-dev and were redirected to this channel but currently we're looking at a more or less bricked device. Any help is welcome
<sanka>
hi tinti ;)
<wingrime>
sanka: you have only ts buttons?
<wingrime>
only-ts based?
<sanka>
sorry, ts-based?
<sanka>
I'm providing you with some pictures
<wingrime>
I mean buttons exists on same plane that screen
<sanka>
wingrime, to get my head around the relations between the components. You, the sunxi communicty, are working to get any linux version working on the AW hardware, right?
<sanka>
are there prebuild uboot images I can test with?
<wingrime>
Also I saw something with a10 and "two cores"
<sanka>
or do I need to compile my own version for the A13?
<wingrime>
sanka: I compile a13_mid
<wingrime>
also you must do serval stuff to help us
<wingrime>
get you fex config
<wingrime>
get you dram config
<wingrime>
and make you board support
<wingrime>
using this stuff
<sanka>
wingrime, I don't mind compiling my own uboot btw, nor do I mind helping you guys out as well.
<sanka>
I need to get experience in this field in order to fix this stuff in the future myself
<wingrime>
sabka: dumping fex config is easy at all
<wingrime>
you simply need few actions for it
<sanka>
wingrime, I realise don't have a working device atm
<wingrime>
techn__: do you have workable CM image for a13 or plans do it?
<wingrime>
techn__: and have you tested 3.4 kernel
<wingrime>
?
<wingrime>
with CM
<sanka>
wingrime, attempt to build a CM image for the device but in the (very) early stages
<hramrach>
wingrime: interesting
<wingrime>
hramrach: I don't want cost money for this crap sun3i
<techn__>
wingrime: yes.. I have working image.. 3.0.52 kernel works fine, current sunxi-3.0 and sunxi-3.4 branches has that USB bug
<wingrime>
techn__: that bug ?
<wingrime>
with ADB ?
<techn__>
wingrime: after boot you have to reconnect usb cable to get ADB working
<techn__>
havent had time to investigate it further
<wingrime>
techn__: I suggest you just add #ifdef for andorid gadget
<techn__>
I thin thats is not good idea
<wingrime>
techn__: undo patch also can't consider as good idea
<wingrime>
techn__: but problem extractly not here
<techn__>
wingrime: yes.. I was planning to find better fix which works every gadget
<wingrime>
techn__: that code.... Is are totaly crap
<techn__>
wingrime: true :)
<wingrime>
techn__: also I want you test performance and respone with my last patches in m git repo
<wingrime>
techn__: I have feeling that last patchas in "dma-rework" branch can make andorid fly better
<techn__>
After checking that code I was planning to do unify patch.. then import latest allwinner changes.. then check what is broken :p
<techn__>
wingrime: yes it looks promissing :)
vinifm has quit [Quit: Ex-Chat]
<wingrime>
techn__: good, I think sun5i and sun4i same
<wingrime>
techn__: I need some "measurable" results with android
<wingrime>
techn__: I can do myself but it requied install CM
<wingrime>
techn__: and downloading and building CM with my channel and CPU cost whole day
<hramrach>
techn__: I don't need to unplug cable to have working gadget on sun4i
<techn__>
wingrime: here it takes half of day :p
<hramrach>
so maybe looking at code difference is good idea
<wingrime>
techn__: about two/one year ago I maintrain CM fork for LG GT540
<wingrime>
with Qurarx
<wingrime>
and I know how much time it costs
<sanka>
I need to install a crosscompile toolchain to build u-boot.. any recommendations?
<wingrime>
I still have core2duo and I not see any measurable progress for upgrade
<wingrime>
sanka: embebian
<wingrime>
techn__: don;t forget test my CM patch for cedar
<wingrime>
techn__: mnemoc want someone test it befor merge
<sanka>
wingrime, that is for debian.. would gcc-arm-linux-gnueabi suffice?
<sanka>
(on Ubuntu atm)
<wingrime>
ubuntu fine too
<sanka>
wingrime, let me get the complete process straight before I continue because I'm kinda confused.
<sanka>
I'm having a device which has a A10s cpu. We installed CWR but we can't control it because we don't have hardware buttons nor does it respond to IR input
<sanka>
on reboot it returns to the CWR because of some bit in /misc is telling it to
<sanka>
booting using u-boot will give me some sort of shell (?) which I can use to clean /misc
<sanka>
does that make sense?
<n01>
with the mainline kernel are u able to boot with rootfs on the MMC?
<n01>
I got stuck on "Waiting for root device /dev/mmcblk0p2.."
<mripard_>
there's no storage drivers in mainline
<mripard_>
so MMC and NAND don't work
<n01>
ook, so, fs in ram?
<mripard_>
yep
<n01>
:) mripard_ you always save my ass :D
<sanka>
is there additional information about the partitions I need to create for script.bin, uImage and boot.scr?
<hramrach>
those ar quite synthetic I would expect
<n01>
yeah, but it is still something
<leowt>
yeah, all with neon
<hramrach>
compiling eg. mpg132 x264, theora with different flags migh give different result depending on code structure and capabilities of your optimizer
<leowt>
hramrach: so it would be best to stick with vfp
<leowt>
and compile neon only on those nneeded packages
<hramrach>
yes, it's good idea to apply exotic optimizations only to pieces of code that are actual performance bottleneck
<hramrach>
and then profile the results
<hramrach>
it's not nice to find a compiler bug manifesting in libpam. And it's not like that needs to be blazingly fast, either.
<wingrime>
hramrach: I detaled readed perf outputs and make sure why aw_clock_src costs so much time
<wingrime>
I relay "not" related clock speed
<wingrime>
and I now know how to fix it
<wingrime>
and will check it now\

ssvb: are you here
<sanka>
wingrime, I've tried both an home build u-boot and the latest a13_mid_hwpack version combined with a bootable debian OS image and both do not seem to load the OS
<wingrime>
sanka: are you connect uart?
<sanka>
hard to tell without any visual clue but the USB keyboard doesn't get any power and the /var/log images stay untuched
<sanka>
untouched*
<sanka>
I don't have an uart
<wingrime>
sanka: there is only one (expect JTAG) know whats wrong
<wingrime>
you defenetly have UART test points
<sanka>
sorry I don't get what you mean
<sanka>
I need to get some hardware and hook it up to the device to read the state of the A10s?
<sanka>
are there any bootable OS-es available for the A10s?
<sanka>
perhaps the bootloader simply works but the OS behind it fails because it expects an A10 and gets an A10s

sanka: uart is "simple console" 3 wire interface
<wingrime>
GND TX RX
<wingrime>
you need find two of this
<wingrime>
TX RX
<wingrime>
and get some UART-USB adapter
<sanka>
with this I can read the state of the chip?
<wingrime>
you will read text output from loader
<wingrime>
and kernel
<sanka>
are there off the shelf solutions for this you can recommend?
<sanka>
or is it custom for the hardware?
<wingrime>
uart are universal over manydevices
<wingrime>
all phone have hidden one
<wingrime>
it used for debug output
<sanka>
but then it is the question where is it located on the board
