Probably not. At minimum, not without modifications. The problem I have
here is that I have no one wire devices to test all this stuff I'm
suggesting to you. Otherwise I'd have a fix for you already.

Thanks for the tip.


I tried correcting that line first to:

gpios = < 13 0>;


and then to 


gpios = < 13 0>;


I'm not sure which of these is correct, though I would have thought it was 
gpios = < 13 0>;



But still no go.


Sounds like I need to change to 4.1.


I see that RCN's link leads to a bash script that allows

more time for detection?  Could this problem be related to 

not enough time being allowed for detection.


Would the script work under 3.8, and might it solve the problem?


Thanks


Matt

The problem is, there are still a few things that do not work properly in
kernel 4.x yet. Or at least the last I heard. It's always worked fine for

Indeed. I would, however, strongly suggest that if it's for work 
connected to op's mail address - Queensland (Australia) Department of 
Agriculture and Fisheries - they move to a 4.1 LTS kernel as it does 
have much better DTO stuff in it etc (from what I've read) and will be

gpios = < 2 0>

 I'm pretty sure is reference to the gpio bank. There is 4 I think
for all gpio's on the processor. The two numbers that follow . . . I
honestly have no idea either.

I can hoever tell you that:
pinctrl-single,pins =  <0x34 0x37 /* gpmc_ad13.gpio1_13,
OMAP_PIN_INPUT_PULLUP | OMAP_MUX_MODE7 - w1-gpio */ >;

0x34 is the pin number, and 0x37 is the pin mode. Which peripheral, or GPIO
mode, whether it's input, or output, and whether pull up, or pull down is
enabled. Pretty much my understanding here is a 32bit field with each bit
indicating *something*.

Eagle eyes!

I’ll try changing that back and see what happens.
I must confess, I don’t even know what gpios = < 2 0>; does.
So I’m not sure where any changes came from.

I think I know what the other line you indicated does.

Using the modprobe w1-gpio produces no output.

Is this where the problem is?

Thanks

So, I'm not 100% sure what the problem is. I've never used One wire in linux - 
ever - And I'm not 100% sure what driver needs to be loaded, if any for this 
specific device. I'm just trying my best to help you troubleshoot the problem, 
because obviously there is something wrong, if the device does not show up on 
several boards, using several devices.
So Matt, I noticed you've changed the GPIO pin here:

gpios = < 2 0>;
But not here:
pinctrl-single,pins =  <0x34 0x37 /* gpmc_ad13.gpio1_13, OMAP_PIN_INPUT_PULLUP 
| OMAP_MUX_MODE7 - w1-gpio */ >;
So do keep in mind that I'm no device tree file expert. So I'm not sure if that 
is bad, or not. But it *seems* wrong to me. Maybe I'm wrong ?

Using the modprobe w1-gpio produces no output.

Is this where the problem is?

My understanding was that 3.8 and above kernels needed no module, simply the 
DTO. It was pre 3.8 kernels that required the kernel module. Or am I missing 
something there? Certainly, every page I'm reading referring to 3.8 kernel 
1Wire has absolutely no reference to kernel modules.
So, perhaps, but if there is something wrong with the device tree blob file, 
the driver wont auto load. Which would give us an indication as to what's wrong.

'modprobe -v w1-gpio' would produce more detail (to test, use modprobe -r 
w1-gpio to unload the module first).

However I'm just reading up and what William refers to seems to be if the DTO 
loads properly it SHOULD load up the module, thus the module not loading is a 
symptom of the DTO not being correct.

I'm currently looking at some other stuff that's indicating that maybe my 
wiring isn't the best.

So, I'm not 100% sure what the problem is. I've never used One wire in
linux - ever - And I'm not 100% sure what driver needs to be loaded, if any
for this specific device. I'm just trying my best to help you troubleshoot
the problem, because obviously there is something wrong, if the device does
not show up on several boards, using several devices.

So Matt, I noticed you've changed the GPIO pin here:

gpios = < 2 0>;

But not here:
pinctrl-single,pins =  <0x34 0x37 /* gpmc_ad13.gpio1_13,
OMAP_PIN_INPUT_PULLUP | OMAP_MUX_MODE7 - w1-gpio */ >;

So do keep in mind that I'm no device tree file expert. So I'm not sure if
that is bad, or not. But it *seems* wrong to me. Maybe I'm wrong ?

Another thing I was noticing after greping the config, at least for my
kernel version. Is that there is no Dallas One Wire kernel module for that
specific device. So it could be that it is compiled in statically. I've
been in menu config several times, and have noticed a lot of Dallas One
Wire drivers, but could not say if that one exists in the kernel, or not .

Hi William,

Please see my original post and you will see the outputs from each of these 
commands.
The driver appears to be loaded perfectly.

2016-04-04 Thread William Hermans 
Starters for troubleshooting. After issuing the commands this person
suggest on that site . . .

cp w1-00A0.dtbo /lib/firmware
echo w1 > /sys/devices/bone_capemgr.9/slots

You should run dmesg | grep w1 to see what the output is. Passed that, are
you sure you have the one wire driver loaded ? I've never actually used one
wire on Linux personally, but there is a generic one-wire kernel module
that I've read about . . .
