[beagleboard] Re: why does reading the DMTIMER clock take so long?
Wow, I completely forgot about this thread until someone just emailed me
with a question. Thanks for your interest.
The file I opened is /dev/mem
int fd = open(/dev/mem, O_RDWR | O_SYNC); //O_SYNC makes the memory
uncacheable
The file is a view of the entire 4GB physical memory space. You need to be
root to open it obviously.
I also have a conjecture about why reading the clock is slow. The DM timer
isn't part of the ARM architecture, so it has to read it externally. Today
as processors integrate more and more devices onto the same chip, packet
switched networks are used more and more instead of dedicated wires since a
packet interface is general purpose and will have higher utilization. But
packet switching will increase latency.
I'd like to know why ARM didn't include a clock as part of the
architectural state. Sure it can save some power, but it practically all
embedded devices need a clock and reading an external one will use more
power. At least one other computer architect agrees:

At 22:30, Burton laments about the lack of a user readable clock on today's
processors.

Sometimes things sound so clear when I write them, but the next daynot so much :) I've created a howto on my blog, for building Qt 5.2 targeted at a BBB running Ubuntu. It is similar to the cloud-rocket site, but using the Linaro toolchain, and I start from the very beginning: Ubuntu virtual machine creation. I tried to be verbose, so maybe you can use it to double check your host configuration. Search for Bare Metal Qt5.2 Beaglebone if you are interested. Qt 5.2 is very different from 4.x (QPA vs QWS), so I am not recommending that you change, especially if you have a working 4.x application.

You would have to write an application/service for your beaglebone that can accept connections/commands.

[beagleboard] Board isnot powering up
Hello Group, Good day. Please bear with me, as I'm a newbie to Beagle Bone Black. Just got the board(Rev-A5A) a few days back. Right since then, I've been experiencing this issue of the board not powering up using the DC power adapter(5V/1A) that I purchased along with it. Upon connecting the power supply pressing the Power button as indicated in the manual, the blue led(D1 as per schematics) blinks faintly nothing happens. I have checked the power supply output of the adapter and that shows 5V DC. However, interestingly, upon connecting the USB cable the board powers ON(blue led D1 glows, followed by the other 4 leds D2-D5) and was booting up properly, up until now. Presently, I observe that the board is not booting any more even when powered via USB : The Led D1 lights up in full brightness stays as such. No further activity is seen on the board nor any messages appear on the serial console. There is no change in the original behavior scenario either - i.e., powering up via the power supply has the same state as explained. Please help. Thanks in advance.

Re: [beagleboard] Re: Beaglebone Black won't power on, did I do something wrong? :(
Sounds like the board may have gotten zapped. Leave it unplugged for 30 minutes, all cables, and try it again. If is still does not work, then you will need to get it looked at.

[beagleboard] connecting a powered hub fixes the hotplug issue?
Hi, Am wondering , connecting a powered usb hub to Beagle bone black before booting will fix the hotplug issue. That is, can I hotplug usb devices to the USB hub, provided USB hub was connected before booting the BBB. Is there any hope this issue will be addressed in the new batch of boards under manufacturing? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Re: CLKOUT2 access in RCN 3.12 kernel?
Thanks for responding..
I did
grep clkout2 *.dts
in both directories and found that clkout2 didn't show up in the 3.8 but
did show up in 3.12
in 3.12 it shows up in am335x-evm.dts and also am335x-evmsk.dts.. (and
dove-cubox.dts but I don't think that is related)
I also just noticed that it also shows up in am335x-bone-common.dtsi,
(3.12) which now seems more likely to be the beaglebone related file.
Here's that chunk from my device tree file..

I used BB-BONE-CAM3 as a starting point but yes, I'm mostly guessing at
what this stuff means.
My next guess is that the last line above is in the wrong section.. clkout2
is not a gpmc pin.
I don't have any /include/ lines in my file.. just
compatible = ti,beaglebone, ti,beaglebone-black;
from the CAM3 file I modified.

[beagleboard] Re: BBB: after powerfailure BBB is no longer booting from eMMC
Hi! OK - I have now taken the minimal image of Debian from: http://www.armhf.com/index.php/boards/beaglebone-black/ And I have copied it to the emmc as well as to an SD card. Again the same observation: the image boots from SD, but nothing happens on the eMMC. Checksums of the boot partitions are: root@debian-armhf:~# md5sum /dev/mmcblk*p1 af7a970e36b360f6b5b65aab04701b65 /dev/mmcblk0p1 af7a970e36b360f6b5b65aab04701b65 /dev/mmcblk1p1 So I wonder what happens BEFORE UBOOT starts (or MLO for that matter). Is it possible that the initial pre-boot loader for the board has gotten corrupted for the eMMC case?

[beagleboard] BoneScript 0.2.4 published on npmjs.org
I've just published BoneScript 0.2.4. I don't expect this to be a very
long-lived release, but I needed to get it out on npm in order to get more
people to try it and report issues.
The primary goals of this release are to support non-Angstrom distributions
and unloading of devicetree overlays such that pins can be reconfigured.
There are also a number of bug fixes, though some needed ones still aren't
incorporated and some new ones are likely to emerge. Please report issues
ASAP as the upcoming new on-board production image will likely contain the
0.2.5 release to incorporate your fixes if you get them in within a couple
weeks.
To install, log into the shell prompt of your BeagleBone (running Angstrom,
Debian, etc. as long as it has capemgr support and a compatible devicetree
http://elinux.org/Capemgr):
TERM=dumb npm install -g bonescript
To verify the installation, execute the following:
root@beaglebone:~# node -pe require('bonescript').getPlatform().bonescript
0.2.4
Feel free to reply here with questions. If you find issues, please report
them to https://github.com/jadonk/bonescript/issues.

[beagleboard] Sending hostname during DHCP
Hi everyone, I'm trying to get the beaglebone to send its hostname to the DNS server when it receives an IP address via DHCP. This is apparently automatic in many distros: http://www.held.org.il/blog/2011/01/make-dhcp-auto-update-dynamic-dns/ Ideally I'll be able to use this hostname when trying to connect to a headless board over the network. I found out that the Angstrom distro uses connman and tried to look for some kind of configuration that would control this but I came up empty. I've asked the connman dist list but I'm asking here as well in case anyone else got it working. The obvious is 'use avahi', however that doesn't seem to work across all of my machines. Although avahi seems to update my windows 7 box fine (hostname.local resolves to the beaglebone), I have windows xp machines and some linux servers that don't seem to be able to see the beaglebone. Note that I can send pings to the beaglebones IP just fine, it's just the hostname resolution that I can't get working. ifconfig on beaglebone shows IP address of 10.101.1.126 (internal work network). Subnet mask is 255.255.252.0, win7 machine on same subnet but my windows xp and linux servers are on different subnets (but all within the mask). I think this is why avahi isn't updating those. nslookup has no entires for my beaglebones hostname, or hostname.local. I made sure that the nameserver on my win machine is the same as the beaglebone. Any ideas? I don't really want to load ubuntu but I may have to just to get the dhclient service to get this working.

We are attempting to use the BeagleBone Black as the on-board computer, however we have concerns with bit flips and single-event upsets that can be caused by radiation. Of course we will be using some shielding, but I would be interested to know if similar projects were undertaken and also what you guys think about the BBB's tolerance to radiation.

Re: [beagleboard] Re: BBB: after powerfailure BBB is no longer booting from eMMC
you cannot use USB power while flashing the board. you MUST use a supply plugged into the barrel connector On 1/17/2014 3:13 PM, Martin Sperl wrote: On Friday, January 17, 2014 7:38:47 PM UTC+1, RobertCNelson wrote: Really none ?... Umm, how are you flashing it? ALL capes removed, NO USB, (ethernet can be plugged in), a real 5 volt DC power (2amps).. No Capes, No Ethernet, Only Serial Console and 5V 2A USB Charger. Only Power and serial connected and I did try it with your image - I was able to verify on the console that the image of yours is working propperly and creating the files - partitioning, rsync,... all working - in the end all LED turned on and everything. Then disconnecting from Power and removing SD card. Then powering it on - nothing happens on the serial line at all... And that is the experience with all the images I have tried--- That is why I am saying there is something VERY strange with my board - at least since I did disconnect it without shutting it down... So I fear that the pre-bootloader (the one loading MLO) is somehow defective and works only for the SD. Martin P.s: my guess is that if I clone the system created by your image on the eMMC to a 2GB SD, then it will boot correctly from SD - I can give it a try tomorrow... -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
