Montjoie: a10 has 3 and a20 has 4
<
tgaz>
Montjoie: seems controlled by twiX_para in the fex (unless you concluded yesterday it's not used anymore)
<
oliv3r>
Montjoie: good question :(
<
Montjoie>
Do you know why I detect only the first I2C bus on cubieboard2 with sunxi3.4 ?
<
Montjoie>
and the TP driver is ugly
<
Montjoie>
the paste has gone
<
oliv3r>
Montjoie: found the reference :)
<
oliv3r>
Montjoie: good question
<
Montjoie>
oliv3r, where is the .c file for thermal sensor which you speak yesterday ?
2013-10-01
<
montjoie[home]>
It have one ?
<
wingrime>
montjoie[home]: in a20/a10 manual
<
montjoie[home]>
oh I see that BMA250 gsensor also have a thermal sensor:)
<
montjoie[home]>
later, I try to find some doc about the touchPad that spoked wingrime
<
montjoie[home]>
My AXP209 is at 30°C
<
montjoie[home]>
How do you have the temperature of thermoncouple , does it is the gsensor ?
<
montjoie[home]>
The temperature by itself is not important, the changes are important
<
ssvb>
montjoie[home]: ok, it works with i2c enabled
<
montjoie[home]>
ssvb does I2C is enabled ?
<
montjoie[home]>
no other patch manualy added
<
montjoie[home]>
I use the sunxi 3.4 sources
<
montjoie[home]>
pastebin dmesg | grep -i axp
<
montjoie[home]>
and CONFIG_AXP_HWMON=y ?
<
montjoie[home]>
do you have CONFIG_AW_AXP20=y in .config ?
<
montjoie[home]>
no
<
montjoie[home]>
DO you have enabled the AXP209 power driver ?
<
montjoie[home]>
and "axp_mfd 0-0034: AXP (CHIP ID: 0x41) detected" before
<
montjoie[home]>
Do you see some axp_mfd 0-0034: AXP internal temperature monitoring enabled in dmesg
<
ssvb>
montjoie[home]: ok, there must be something else there, because lm_sensors does not see anything
<
montjoie[home]>
ssvb I confirm, CONFIG_HWMON is necessary for building
<
montjoie[home]>
another driver todo:)
<
wingrime>
montjoie[home]: see manual for a10/a20
<
wingrime>
montjoie[home]: yes
<
montjoie[home]>
I have read that A20 is just an A10 with better cpu/gpu, so perhaps the A20 have also this TP ?
<
wingrime>
montjoie[home]: touch-panel
<
montjoie[home]>
TP ?
<
wingrime>
montjoie[home]:a10 have own internal termal sensor in TP module
<
montjoie[home]>
It is what I said with the link or you speak with another thermal sensor ?
<
wingrime>
montjoie[home]: a10 have internal ternal sensor too
<
montjoie[home]>
It has both
<
wingrime>
montjoie[home]: may be only support batt-internal sensor connect
<
wingrime>
montjoie[home]: not sure termal sensor in axp
<
montjoie[home]>
I use a cubieboard2 (A20)
<
montjoie[home]>
The thermal is sensor is located on the AXP20x power management which is used by A20 and A10 I believe
<
ssvb>
montjoie[home]: what kind of device are you using for tests yourself?
<
ssvb>
montjoie[home]: is axp20 thermal sensor related to battery or something like this? or does it work on any a20 device?
<
montjoie[home]>
ssvb I think I forgot to add some selects CONFIG_HWMON
<
ssvb>
Montjoie: what is needed to get your axp20 thermal sensor patch to work on cubieboard2?
<
montjoie[home]>
I see patch for A20 SMP support, does the current sunxi 3.4 does not handle it ?
<
Montjoie>
arg, neither send a patch without testing the last minor change...
<
Montjoie>
I will see that
<
oliv3r>
Montjoie: we have some test code, dunno what happened with that
<
oliv3r>
Montjoie: the touchpad controller has a temperature sensor embedded
<
Montjoie>
If you find/know other resource of temperature I am interested
<
Montjoie>
i said 202 because the datasheet is for 202
<
Montjoie>
oups yes
<
Montjoie>
no, I use the internal die of the AXP202
<
oliv3r>
Montjoie: any chances of it working on a10? i assume you are using the temperature sensor
<
Montjoie>
ok thanks
<
n01>
Montjoie: please, register
<
Montjoie>
No need to register to his mailing ?
<
Montjoie>
For a thermal driver, flame must be avoided:)
<
n01>
Montjoie: to avoid flame, please use git-email :)
<
Montjoie>
Hello I have a patch for adding thermal monitoring for AXP20 of the cubieboard2, where can I send it ?
2013-09-27
<
Montjoie>
steev, for thermal monitoring I found somethin in the axp209, but I must code the driver
2013-09-20
<
tgaz>
Montjoie: yes, the sunxi framebuffer and the sunxi HDMI driver (AFAIK)
<
Montjoie>
so I need the framebuffer
<
oliv3r>
Montjoie: once the kernel initializes those +fbdev you can see the rest of the bootlog
<
oliv3r>
Montjoie: there's no HDMI or display driver in u-boot
<
Montjoie>
Why I cannot see the boot on HDMI display wih the cubieboard2 ? Does I need to activate/change something ?
2013-09-19
<
montjoie[home]>
in ext2load mmc 0 0x43000000 boot/script.bin what does mean 0x4300000 ?
<
montjoie[home]>
ok thanks I read the wiki
<
wingrime>
montjoie[home]: you need uart for find whats wrong
<
montjoie[home]>
And when I use the arch bin that work, the kernel dont load...
<
wingrime>
montjoie[home]: we have many guides , but we can't control all for fresh
<
montjoie[home]>
ok
<
montjoie[home]>
but I have done all that it is writed in the guide
<
montjoie[home]>
it is the uboot built by myself that dont work
<
montjoie[home]>
it is that I have done
<
wingrime>
montjoie[home]: rebuild uboot by yourself
<
montjoie[home]>
so I think it is the 2 bin that dont works, but wy ?
<
montjoie[home]>
If I replace sunxi-spl.bin and u-boot.bin by arch's one green light appears and it works

Does someone have a working .config for linux-sunxi kernel sources for Cubieboard2 (A20)
<
oliv3r>
Montjoie: though i RFCed very early sata a few days ago
<
oliv3r>
Montjoie: if you want a usable kernel; yes, 3.4
<
Montjoie>
So for SATA I still need linux-sunxi sources ?
<
oliv3r>
Montjoie: but you won't have much support, only initramfs + enthernet
<
oliv3r>
Montjoie: 3.11/3.12
<
Montjoie>
hello, from which version can I use vanilla kernel on cubieboard2(A20) thanks?
