<oliv3r> Montjoie: a10 has 3 and a20 has 4
<Montjoie> On http://comments.gmane.org/gmane.linux.ports.arm.kernel/266025 i see that I must have 2 I2C bus
<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]> According to http://linux-sunxi.org/AXP209 you will find on A10 A13 A20 SoC
<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
<Montjoie> ok
<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> thanks
<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

<Montjoie> thanks
<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
<montjoie[home]> Hello I have a cubieboard2, I have done all steps in http://linux-sunxi.org/FirstSteps (for dev) and nothing works, any idea ?

<Montjoie> 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?
