A13 MICRO kernel installation

[JohnS]

So what speed is the camera that means you abandon the Micro?  Is it HS?

(And about the LCD Screen ?)
Well about the UVC Camera I have no idea... of why, but sounds a good idea to try with the USB OTG, let us know if it works.

[JohnS]

From what I can see if it's HS it won't work at all with the Micro.

This is rather basic USB information you need to know about the camera!!

(about the LCD problem I just found out, see my topic about that if interested)

I finally got a successful kernel build, thank you for the help. 

I used:
git clone git://github.com/linux-sunxi/u-boot-sunxi.git
git clone https://github.com/hehopmajieh/linux-sunxi
cd linux-sunxi
git checkout origin/sunxi-3.0
make a13_olinuxino_micro CROSS_COMPILE=arm-linux-gnueabi-
make ARCH=arm a13om_defconfig
make ARCH=arm menuconfig


loaded the .config from:
http://dl.dropbox.com/u/22273442/A13/.config
etc...

Hi Cure.

When you type make ARCH=arm a13om_defconfig the make create a .config specific for your board. If you catch my .config in dropbox, you overwrite .config produced by make ARCH=arm a13om_defconfig. So is better not use my config, because AXP209 is enable.

But this shows that no matter the .config, considering that worked. The main thing is the kernel and bootloader.

[JohnS]

A good thing to read is Documentation - there is plenty about the kernel build process and it explains the config etc stuff.

the difference between A13-MICRO and A13-WIFI is the USB hub GL850G, original A13 USB is only HIGH SPEED so if your camera is not supporting high speed USB it will not be able to connect

by the way USB-OTG port can be also Full Speed USB host with the USB-adapter it supports even keyboards and mouses https://www.olimex.com/Products/Components/Misc/USB-MINI-2-USB-HOST/

Hello,
I have a  TP-Link WN727 usb wireless adapter that I can't get it to work on the Micro.
It works fine on another embedded system with the same arm and same kernel.
I don't know if this is the problem, but i tried almost everything and it doesn't work. The rt2800usb module is loaded, i get the usb device in sysfs, but the subcomponents are wrong and i can't generate a /dev/wlan0 whatever manual udev rules i use... :-(

However, if I use the otg adapter and use the second mini usb, I loose the otg functionality of the device ( which it must have ).

did anyone try an usb wlan stick with the micro and got it working ?

Thank you very much.

Try ath9k_htc.ko: http://linuxwireless.org/en/users/Drivers/ath9k_htc

[agross]

Ath9k ?
But on an embedded geode x86 and on another embedded arm board works fine with rt2800usb ... :/
Anyways, thanks a lot, i'll give it a try tomorrow.

[JohnS]

Which other arm board?
