Olinuxino Lime Allwinner A10

[conchyliferous]

Hello.

I installed Arch Linux Arm on an Olinuxino Lime. Since the device is not listed under Devices I did it in a slightly different way. First I dd:ed the Debian image supplied by Olimex (https://www.olimex.com/wiki/A10-OLinuXino-LIME) to a memory card, then I cleared the second partition and put the Arch root there instead (http://archlinuxarm.org/os/ArchLinuxARM-sun4i-latest.tar.gz). In that way I though that the bootloader, the kernel options, the fex file, and so on should be OK. I did not copy the uImage file from Arch. Everything worked fine, the device boots and I have updated the software etc. However, I can't access the GPIO pins. Or I simply dosen't know how to do it. Any suggestions? I've seen some notes about a sunxi-gpio kernel module, but how do I get that?

I tried to cat the /sys/kernel/debug/gpio, but it's empty.

On the boot partition I have (all taken from the Debian image):
boot.scr, script_a10_lime_HDMI.fex, script.bin, uEnv.txt, uImage

Please help me out here.

I don't see why our kernel would not work, since sunxi has just the fex file & uboot that are different.

Thanks for your reply.

The kernel works fine in the sense that the board boots and behaves properly. The fact that I can't access the GPIO pins might simply be due to me not knowing what to expect. I'm very used to Arch Linux, but it's the first time I want to use GPIOs. What I want to know is perhaps (in general) how the pins are initialized, and how to debug them.

I don''t have your hardware, but I can probably get you started.

first look in /sys/class/gpio
you should find export, unexport and gpiochip1 (or something similar)
if so, you have gpio enabled in the kernel.

then look at your .fex file. (decompile it if necessary with bin2fex.
in there you should find a section named gpio_para

$this->bbcode_second_pass_code('', '[gpio_para]
gpio_used = 1
gpio_num = 2
gpio_pin_1 = port:PH20<1><default><default><1>
gpio_pin_2 = port:PH10<0><default><default><0>
')
This is an example in my fex (A20)

gpio_used should be 1 (0 means not used)
gpio_num in this case is 2 (2 gpios defined)
the rest are pin definitions with muxing and defaults

In this fex there are two pins enabled, pin 1 and pin 2

Now back to /sys/class/gpio
type sudo su (you need to be root)

type echo "1" > export (enable pin 1)

if you see "write error: Device or resource busy" this means the pin is already claimed.
if you see "write error: Invalid argument" this means this pin is not defined in the fex.

a new directory should appear, in my case named gpio1_ph20
in that directory you find the gpio controls and data

If you want to free the pin again type echo "1" > unexport

Again I don't have your hardware so things might look a tad different.

Success, LP

Thank you for your very clear and good answer!

It doesn't really work out though.

In /sys/class/gpio I only have export and unexport. When I try to write to export i get:
$this->bbcode_second_pass_code('', '# echo "1" > export
-bash: echo: write error: Invalid argument')

I tried several different ports.

Do I perhaps need to load any kernel modules or something?

The only thing I notice is that you listed 76 gpios, but declared 75 to be present.
If that is allowed or not I don't know.

Did you check here? http://linux-sunxi.org/GPIO, Maybe it helps.

I forgot...
type :
cat /proc/config.gz | gunzip | grep CONFIG_GPIO_SUNXI

you should get CONFIG_GPIO_SUNXI=y

when GPIOs are enabled in the kernel

That was the clue I needed! It works perfectly now.

The thing was that I got an 'm' for CONFIG_GPIO_SUNXI. And then I realised that the problem was the kernel image I saved from the previous Debian system. That image said 'm', but the actual module was not still around since Arch assumed a 'y'. So I dared to put the uImage from the Arch install on boot. The board still booted and worked like a charmer!

Thanks for all the help. I would hope that someone would put this kind of useful things on a wiki somewhere.

Also I belive that this is the first note that Arch Linux Arm work fine on an Olinuxino Lime. Hope that will make someone happy.

see, WarheadsSE was right (again).
