Re: [beagleboard] Re: BBB freezing

[alejom . tv]

I had this same problem.

I had to disable the "cpu-ondemand" feature

rm /etc/systemd/system/multi-user.target.wants/cpu-ondemand.timer

Now it works

Do you have a link to the "instructable"? Some of the ones you find should 
be called "DESTRUCTABLES"

I have used a number of "USB 2.0 3-port hub with Ethernet" units in the 
past with Beagle Boards (not specifically the bone).
I don't recall the chip in them.  They usually run about US $9 from China.  
I rip them apart, cut off the
USB sockets and build them into the cabinet of my unit.  These have worked 
well.  The very first time
I did this I needed to rebuild the kernel, since then the Robert Nelson 
kernels have supported that
unit without special attention. Sorry, I don't have one unboxed here to see 
what the chip is.

I have not specifically tested this with the bone, but it really ought to 
work fine there, too.

It's id changed those 9 times, look at the kernel patch and port it to
the cpsw driver in u-boot:

Re: [beagleboard] Beaglebone Black Ethernet Phy Not Detected on Boot.

[John Zhang]

Hi Alex,

I added this delay 1 second idea on the u-boot version v2015.01 and did the 
power on / off test on BBB. I did 263 board boot up. Among them 254 times 
Ethernet interface successfully started up. The other 9 times the u-boot 
just could not detect Phy. Below is the u-boot log comparison between a 
successful boot and a (Ethernet) bad boot - 

Successful one:

U-Boot 2015.01-dirty (Feb 13 2015 - 00:46:39)

   Watchdog enabled
I2C:   ready
DRAM:  512 MiB
MMC:   OMAP SD/MMC: 0, OMAP SD/MMC: 1
Using default environment

Net:not set. Validating first E-fuse MAC
cpsw
Hit any key to stop autoboot:  0 
gpio: pin 53 (gpio 53) value is 1
switch to partitions #0, OK
mmc0 is current device

Checking for: /uEnv.txt ...
Checking for: /boot.scr ...
Checking for: /boot/boot.scr ...

..


Bad boot:

U-Boot 2015.01-dirty (Feb 13 2015 - 00:46:39)

   Watchdog enabled
I2C:   ready
DRAM:  512 MiB
MMC:   OMAP SD/MMC: 0, OMAP SD/MMC: 1
Using default environment

Net:not set. Validating first E-fuse MAC
Phy 0 not found
cpsw
Hit any key to stop autoboot:  0 
gpio: pin 53 (gpio 53) value is 1
switch to partitions #0, OK
mmc0 is current device
gpio: pin 54 (gpio 54) value is 1
Checking for: /uEnv.txt ...
Checking for: /boot.scr ...
Checking for: /boot/boot.scr ...
Checking for: /boot/uEnv.txt ...
..



Note the "Phy 0 not found" line shown in the bad log.

So unfortunately this idea does not work here. The Ethernet failure rate is 
about the same with or without this 1-second delay added or not. The hunt 
has to go on...

Well, why did you update your /etc/apt/sources to point to
"old-releases.ubuntu.com" "trusty" is not there yet... (in a few years
it'll be..)

Did you include the netmask 255.255.255.0 line? You should probably send

[beagleboard] CAN-CAPE TT3201

[Andrew P. Lentvorski]

Beaglebone black newb here.  I've been fighting with various problems with 
getting CAN to work and not really getting anywhere.  Does anybody have a 
detailed set of instructions for the TT3201?

I'm trying to use the onboard Beaglebone Black CAN which is routed directly 
to a transceiver to avoid the extra problems with SPI.  I expected this to 
be built into the distribution, but apparently it is not.

In addition, it seems like can_utils, can-utils, or canutils have become a 
victim of bitrot and berlios.de going down.  Almost all the tutorials have 
"cansend can0 -i 0x11 0x22" when the cansend command I have supports 
"cansend can0 FED#DEADBEEF".  In addition, I don't even have a "cancontrol" 
command.  Clearly, *something* has changed significantly.

I've got my scope connected, and nothing external is toggling.  Do I have 
to use Angstrom or Debian?  Is there a particular image I need to load to 
make this work?  Am I doing something completely stupid (almost certainly)?

Any pointers would be useful.

Thanks.

[beagleboard] Device tree: bind to alternate driver, or dummy entry?

[sbattazzo]

Hello,
I have an alternate driver  (xeno_16550A) that I would like to try to use 
for one UART while using the regular omap3-serial for all the others.

Is there a way to specify in the device tree which driver to use?

Alternately, could I have some kind of dummy entry in the device tree which 
just handles the ti,hwmods and pinmux parts without binding a driver to 
that device's address? It seems like the ti,hwmods part is what gets the OS 
to call the write to the CM_PER_xx register to enable clocking to each 
peripheral's registers.. Am I correct on that?

With that fixed I can just modprobe the driver I want which is perfectly 
acceptable.

Cheers,

Steve

Try this:

auto eth0  
iface eth0 inet static
address 192.168.1.26
netmask 255.255.255.0
gateway 192.168.1.1

That worked for me.

[beagleboard] Wish to use a USB to Wired Ethenet Adapter?

[COG]

Dear Sir/Madam:

I have a Rev. C BBB (Debian) board and I would like to add an additional 
Wired Ethernet Adapter via the USB port.  Examples:

(a) "Plugable" USB 2.0 to 10/100 Fast Ethernet LAN Wired Network Adapter 
for Macbook, Chromebook, Windows 8.1 and Earlier, Surface Pro, Wii, Wii U, 
Linux, and Specific Android Tablets (ASIX AX88772 chipset) 


(b) "Cable Matters" USB 2.0 to 10/100 Fast Ethernet Adapter in Black 


*I would like to know:*
[1] If any one out there has used any of the above or other with success on 
the Rev C boards(*Debian*)?
[2] Any advice would be welcomed?

*Note:* I know I can use a wireless Ethernet Adapter, but I prefer to use a 
wired version in this case because of security reasons.

Thanks & Jesus' Love
Roger

[beagleboard] Static IP on eth0

[Enric Climent]

Hi! I put latest jessie debian snapshot from 
here http://elinux.org/Beagleboard:BeagleBoneBlack_Debian

Well, i want to have an ip to the beaglebone. I put this in 
/etc/network/interfaces:

auto eth0
iface eth0 inet static
 #your static IP
 address 192.168.1.26
 #your gateway IP
 gateway 192.168.1.1


But when restart the ip are 192.168.1.130 (provided by DHCP server). If 
after reboot i execute /etc/init.d/networking restart then ip change to 
192.168.1.26 but if i ping 192.168.1.130 the beagle responds correctly.

So Any ideas? Thanks!

Re: [beagleboard] Jessie snapshot 2015-02-01 without usb networking

[Enric Climent]

Ok, so i solve it! I do this;

#apt-get install linux-image-3.8.13-bone70

#reboot

#apt-get install mt7601u-modules-3.8.13-bone70

#apt-get install am335x-pru-package ap-hotspot dart-1.8 dart-edge 
oracle-java8-installer ti-pru-cgt-installer xenomai-runtime cloud9-installer

Re: [beagleboard] Rpi2 + Windows 10. Who's gonna buy BBB?

[William Hermans]

The ODROID's look rather intriguing, but if you dig deeper and have an idea
what you're looking for. They're lacking in many departments. Mostly,
they're not open sourced, and despite looking around a while a few times.
I've yet to determine whether they have a decent BSP or not. Not to mention
that their IO capabilities are rather limited / far less than say any of
the beagle hardware. Which if needed, that is very important. Then, TI
processors are the only ones available with PRU's, for "software definable"
hardware - As far as I know anyhow.

These boards *are* rather interesting in that they could serve as a "build
system" for just about any ARMv7 SBC, but . . .AFAIK, the rPI group (
community ) could not find a way in software to disable the on die GPU,
thus the rPI's lose X amount of the on board memory to the GPU. Even if you
wish to use it or not. So, since the new board uses the same GPU . . . let
us hope this problem is / has been resolved.

Now for anyone who does not already know . . . I use Windows daily for
multiple purposes on my own personal systems, and am very happy with it. So
when i say that Windows has no place in the embedded market space ( at
least in this context ). You all can know where I am coming from. Passed
that, yes of course MS is not stupid and is not going to let you, I, or any
other average non partner Joe in a commercial application without probably
a very hefty fee. So, if you think you're going to be able to use the rPI2
with Windows on it in this capacity . . . you're in for a very rude
awakening.

With that said. I very seriously doubt MS is scared about anything
concerning the embedded market. They're just doing what any software
company would / should do in their shoes. Granted they have a very poor
track record outside of the x86 arena . . . but yeah. There was CE, and
every version of Windows from XP on had an embedded version. All revolving
around x86, and guess what ? You can not hardly go into any retail store in
the US, and not use a Windows system when you check out. Via self, or
cashier . . .

Re: [beagleboard] Re: Beaglebone Black not booting due to modification of uEnv.txt

 It does, I use the console port with a RS232 converter at 115K. I have 
soldered a R/A connector at the back of the board so that I can use it even 
if a cape is plugged in. It's designed to use a "standard" FTDI USB > TTL 
adapter.

The image I downloaded before was just a stripped down, console only, 
version which booted from SD. This allowed me to recover the EMCC version 
after fixing up the uEnv.txt file.

The serial port console starts spitting out stuff even before the USB COM 
port does.
