[beagleboard] Re: eth0 mysteriously stops working

[William Hermans]

Sorry I missed putting the decompile step in my workflow. This is the very 
next step that is used after making a copy of the board file form the 
/boot/dtbs// directory:
dtc -I dtb -O dts -o am335x-boneblack-emmc-overlay.dts am335x-boneblack-emmc
-overlay.dtb

Re: [beagleboard] Re: eth0 mysteriously stops working

[William Hermans]

Ok,I had to modify my workflow, but I do believe I got the changes put into 
place. Not sure why Robert's way was not working, but I'm used to thinking 
outside the box, or looking at multiple ways to achieve the same results . 
. .

You board file name, and kernel version will depend on which board file you 
need to use, and which kernel you're running . . .

william@beaglebone:~/dev$ cp /boot/dtbs/4.1.34-bone-rt-r24/am335x-boneblack-
emmc-overlay.dtb .


* Search for "sleep"*

* Line 810-814 for me, remove:*

 cpsw_sleep {
pinctrl-single,pins = <0x108 0x27 0x10c 0x27 0x110 
0x27 0x114 0x27 0x118 0x27 0x11c 0x27 0x120 0x27 0x124 0x27 0x128 0x27 0x12c 
0x27 0x130 0x27 0x134 0x27 0x138 0x27 0x13c 0x27 0x140 0x27>;
linux,phandle = <0x37>;
phandle = <0x37>;
};



*line 816-820 remove:*

davinci_mdio_sleep {
pinctrl-single,pins = <0x148 0x27 0x14c 0x27>;
linux,phandle = <0x39>;
phandle = <0x39>;
};


*Line 1827 change:*
pinctrl-names = "default", "sleep";



*to:*
pinctrl-names = "default";



*Line 1841 change:*
pinctrl-names = "default", "sleep";



*to:*
pinctrl-names = "default";



*Line 2165 delete this whole line:*
cpsw_sleep = "/ocp/l4_wkup@44c0/scm@21/pinmux@800/cpsw_sleep";



*Line 2166 delete this whole line:*
davinci_mdio_sleep = 
"/ocp/l4_wkup@44c0/scm@21/pinmux@800/davinci_mdio_sleep";



*Then save, and exit the file. After that rname the old board file:*
william@beaglebone:~/dev$ mv am335x-boneblack-emmc-overlay.dtb am335x-
boneblack-emmc-overlay.dtb.old



*Now compile the newly edited source file back into the original board file 
name / extension:*
william@beaglebone:~/dev$ dtc -I dts -O dtb -o am335x-boneblack-emmc-overlay
.dtb am335x-boneblack-emmc-overlay.dts



*For convience, since I use an NFS share to do most of my work on, I prefer 
to move both the new dtb, and old dtb to the destination:*
william@beaglebone:~/dev$ sudo cp am335x-boneblack-emmc-overlay.dtb* /boot/
dtbs/4.1.34-bone-rt-r24/



*Double check:*
william@beaglebone:~/dev$ ls /boot/dtbs/4.1.34-bone-rt-r24/ |grep emmc
am335x-boneblack-emmc-overlay.dtb
am335x-boneblack-emmc-overlay.dtb.old


*Reboot:*
william@beaglebone:~/dev$ sudo reboot


Now do keep in mind. Just because I'm calling out line numbers here does 
not mean they will be the same for you. But if you use a good text editor, 
you can search for "sleep", and should only find these 6 occurrences in 
your decompiled source file. With that said, always double check to make 
sure what you're deleting / changing, is actually what needs to be changed.

Actually, device tree file(s) were involved, you just did not realize it.
By using config-pin, you're using one of the universal IO device tree
overlays.

So, I do not really know much about the SPI hardware per se. However, I do
know that if you check an overlay file for SPI, say :
https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/BB-SPIDEV0-00A0.dts#L63
Look at the highlighted line. If you're wanting to raise the frequency,
there is is. But except if you're wanting to use a universal IO overlay,
which I completely understand. You'll have to edit the file that is
preloaded at boot, *or* the overlay file that is loaded when you invoke the
config-pin script.

As far as the clock, and divider . . . Well as I recall the clock is 48Mhz,
which means if the frequency is 16Mhz, the divider is 3x. Anyway, as I said
I really do not know the SPI hardware well. SO take what I say with a grain
of salt. As what I'm saying concerning the clock and divider is going by
memory. Where I've never used the hardware, and my memory is sometimes less
than perfect.

[beagleboard] Changing SPI0 Clock Rate

[George Rung]

I am able to get *SPI0 *working on the BeagleBone Black by using only 
*config-pin* commands:

config-pin P9_17 spi
config-pin P9_18 spi
config-pin P9_21 spi
config-pin P9_22 spi

Then writing to */dev/spidev1.0 *causes data to come out the pins P9_18 
(data) and P9_22 (clock).

Note that searching for how to enable SPI on the BeagleBone returns 
tutorials that all involve *"device trees"* or a *"cape manager"*.  None of 
this was necessary for me to get SPI working.  I assume they used to be 
required at some point in the past.  I simply set the pins to SPI and it 
works.

Now I'd like to change some SPI settings, like the clock rate.  It seems 
the hardware has a frequency divider that can be set to change the SPI 
clock rate.  What is the clock rate by default?  How can I change it? 
 Ideally I'd like to change it by command with the BeagleBone running, 
hopefully no recompiling or rebooting required every time I make a change.

How should I go about this?

Note that I'm running the image

So after decompiling the two files and comparing with diff, then piping to

 Thanks again Robert,

 So I'll have to download the overlay board file repo, edit, and then
 install but hummm. Been a while I need:

 ##BeagleBone Black: HDMI (Audio/Video) disabled:
 dtb=am335x-boneblack-emmc-overlay.dtb

 Which probably loads the common overlay file, so . ..yeah ok think I
 got it. Going to be busy today with other things( unavoidable ) so might be
 tomorrow before I can write back success in modifying the board file. After
 which I can hopefully get this modification out to be tested on multiple
 boards by this person I know.

 I'll post full instructions for others here, when I get the chance. SO
 others can test, and potentially fix the same issue if needed.

Then I got screwed by their US company or RS violated their agreement with 
their US outfit. When I tried to order I was rerouted to 
https://www.alliedelec.com/
When I talk to the sales person he told me that RS UK outfit was not allowed to 
ship it directly to me and that I had to go thru them. So they charged me for 
shipping to the Texas and from Texas to Michigan plus other charges which 
totaled $313.26 plus
around $15 for shipping from Texas to Michigan

So was he lying? or did RS export violated an agreement with their US.

Here is the Email of the salesperson if you want to check or insult him.

jeremy.c...@alliedelec.com


He even assured me that it was a version that was FCC approved.

Re: [beagleboard] How can i install Virtualbox on my Beaglebone black ? i am using beaglebone 7.9 wheezy version.

[William Hermans]

First, you're going to need the right software architecture, but as you've
already seen. I seriously doubt you're going to find an armhf ABI
compatible binary.

Then, even if you did find a compatible armhf binary, assuming virtualbox
could, or would run off such minimal resources. It would be so slow it
would drive most people insane . . .

[beagleboard] Can x15 sustain 1 Gbps Ethernet transfers?

[Rick Mann]

I'm curious, can the x15 sustain a large transfer at 1 Gbps? To/from memory is 
fine, so writing to Flash is not the constraining factor.

I'm interested in making a network speed test appliance.

It brings us to their US outfit who order it from the UK and then
send it to us. It is not straight from the UK.

How much did you pay for yours? Mine ended up close to $335

It might have been cheaper for you if your ordered yours after me.
At the time they had no US stock and told me that the brits could
not sell directly since the USA market is reserved to them.
He also told me that he was going to add it to their USA site.

Opps, i'll need to patch around the bluez requirement:

https://github.com/rcn-ee/repos/blob/master/bb-wl18xx-firmware/suite/jessie/debian/control#L11

Otherwise that'll double the console size..

Re: [beagleboard] What is the latest BBGW image?

Hi,

I really like the "console"versions of Debian for BeagleBone but when I 
tried it on my BBGW and ran a ifconfig, there was no wlan in the list (just 
usb and lo).
Could you detail just a bit how to install "bb-wl18xx-firmware" ?

I have the latest console image (
bone-debian-8.6-console-armhf-2016-10-06-2gb 
)
 
on a SD card and can boot on it on my BBGW. I can ssh to it through usb or 
use FTDI but I I don't have Internet access on it.

Thanks !

Chris is correct.  If you want to order from RS components you have to go

That's really strange, because I successfully purchased a board from them. 
 They shipped from UK to California.

I ordered from this site:

The rev A2 that they have works fine, as well as the Rev 3 boards that I

Oops...I've been using the eCAP in the PRU sub-system, which does have
5 nS resolution (200 MHz clock).  I forgot the normal system timers
have a slower 100 MHz clock, so only 10 nS resolution.

Still *WAY* better than anything a software loop can mange!  ;-)

[beagleboard] Problem booting on Beagleboard X15 Rev B1

[Catudal Michel]

I got two of the Beagleboard X15 Rev B1 and have not been able to boot the 
MicroSD TI Linux (generated by yocto) on it. The previous release with 
kernel 4.1 boots OK except that it is set in a low resolution, not the 
1920x1080 expected resolution.

I tried the same image on three rev A3 from TI and 1 rev A2 beagleboard 
X15, they all work as expected.

If I replace u-boot from TI with the one from Beagleboard X15 I get a 
different error, log after the first log

Here is the log

Re: [beagleboard] Time beween pulses

[TJF]

eCAP is the right module to use.

The resolution is up to 10 nS (100 MHz clock), so the maximum frequency is 
50 MHz.

Find a code example (C syntax) in libpruio 
 package, documentation here 

.

I've set my delivery to abridged summary. That way, the spam doesn't wind 
up in my inbox, and it's also a neat way for me to skip posts I may not be 
interested in

Use an eCAP timer input pin.  That's what the eCAP capture-compare
timers are for...they capture the rising and/or falling edges of
signals and record the time it happened with up to 5 nS resolution.
