mnemoc: under android, meminfo shows a dram clock of 360, but shows 408 under linaro
<servili007>
likely because the dram settings under u-boot-sunxi set it as such. Does that need to be corrected? it seems to run fine at the higher clock
<servili007>
ah, hold that thought, I need to double check something
<countz>
weird, two browsers I tried can not reach any web site on my A13

stefanro1 has quit [Ping timeout: 246 seconds]
<libv>
Skaag: so your lcd works with the olimex provided .fex?
<Skaag>
libv: Yes, the problem was that mod_gpio wasn't compiled into the 3.0.52 kernel
<Skaag>
and without this module enabled, pin 15 was not powered, so the LCD remained dark (pin 15 enables the backlight)
<Skaag>
sorry, I mean that sun4i-gpio.ko is missing in the kernel I built with sunxi-bsp
stefanro has joined #arm-netbook
<Skaag>
libv: Also notice that the .fex has to be a special .fex crafted for non-android OS's such as Debian or ArchLinux, which do not have a pwm module.
<Skaag>
it's configured to enable pin 15 on the gpio
<Skaag>
Android has a pwm module, which basically controls the brightness of the LCD's backlight by changing the width and modulation of the pulses.
<Skaag>
By powering on pin 15 constantly, the LCD is stuck on the highest brightness, but at least it works, and does not require a pwm module.
<Skaag>
right now I'm stuck with something else. on debian, a patched x86-xorg-input module which uses a patched tslib, gives me a segmentation fault.
<Skaag>
I'm going to try to debug it tomorrow.
<Skaag>
I have a feeling it's my kernel being too strict with that android paranoia thing
<Skaag>
so maybe the first thing i'll do is try to compile 3.0.52 again, this time with the sun4i modules.

Skaag: the issue sounds weird though, could it be that we need to add support for another gpio in the pwm code for the lcd?

the problem is that this is for this specific lcd, for this a13 model

but the instructions are broken, with several mistakes

slapin_, the boot blocks are read very differently than any other area of the nand.
<hno>
The random seed per page is hardcoded to 4a80 on every page, and ECC layout is sequential with sector data and ECC interleaved (SEQ bit set in controller flags).
<hno>
There is also only one ECC format used.
<hno>
and no detection of what nand chip is used. Ony how many address cycles the chip needs.

slapin_: the same set of peripheral and the HUB works on other board/kernel.
<ar_vr>
slapin_: any idea about the ratings of the HDC of the allwiner processor.
<slapin_>
ar_vr: I think it is up to axp209 or other power chip
<slapin_>
ar_vr: just try external psu with your hub and see
<slapin_>
ar_vr: sticks come with very bad psus without appropriate capacitors and don't give out enought power
<ar_vr>
slapin_: yes,its already external power supplied USB HUB
<slapin_>
ar_vr: try inserting all devices into your hub and then attach it to usb host and see what happens.
<ar_vr>
slapin_: Actaully we ourselves designed this HUB board and not a commerically purchased one. its working on another tablet device.
<slapin_>
ar_vr: regardless, try with all devices inserted and power attached and see what happens (if you have hub power properly wired and Zengers/Schotky at appropriate places)
<slapin_>
ar_vr: or you might damage poorly designed USB host power (if it is poorly designed)
<ar_vr>
slapin_: I tried it connecting all the devices and then connecting the hub to the device. its the same result.
<ar_vr>
slapin_: I googled a bit on this error and it appears that this error is most often seen with sunxi/allwinner driver but no resolution seen.

i've got a 4670 but it causes me grief, i think it's because i have a supermicro motherboard with tihs dual xeon

chromeos/chromiumos are built on top of gentoo, i thought everyone knew that

it's why google keeps recruiting the hell out of gentoo devs

<steev_>
though recently it seems that hrw got some packages
