Hi, I wanted to update my BeagleBone Black Rev C, but unfortunately I only found a lot of images for the BBB with 2Gbytes of eMMC, none for the BBB with 4 Gbytes. Did I miss something?

[beagleboard] How can I use PRU by CCS Compiler?
I 'm very confusing with many tutorial for PRU. And Now I have CCS Compiler/Editor with PRU library. I have example code/Project from PRU_Cape. But I don't know what should I do next step with all file in Released folder with my beaglebone? And what should I do in beaglebone? How can I make device tree source file? How can I compile my C source code and flash to PRU's program memory? Does anyone recommend a tutorial to use PRU with CCS Compiler?

Fedora follows the upstream kernel very closely, and the beaglebone works very well for me except for this power down issue. Full pmic shutdown should fully work as of the up coming v3.19-rc merge.

[beagleboard] How to Nest 5 Callbacks in Bonescript/JS
I need to be able to have 5 functions that happen in a single function that
are the same command with different parameters each time. I have read
through many tutorial and looked at a few examples and tried to implement
it with no success. I think I understand the function of callbakc but I
can not figure out how to implement it with more than 2 deep.
Here is the 5 calls I need nested each line is calling the same function
with different parameters passed to it.
function send(Callback) {
var Angle = document.getElementById(DampAngle).value;
var AtCmd6 = 0x4 ;
var AtCmd4 = 0x4 ;
var AtCmd3 = 0x4 ;
var AtCmd2 = 0x4 ;
if ((Angle 0x8) == 0x8) { // ANGL[3:0] = [D6, D4, D2, D1]
atCmd6 = 0x05;}//
else {
atCmd6 = 0x04;}//
if ((Angle 0x4) == 0x4) { // ANGL[3:0] = [D6, D4, D2, D1]
atCmd4 = 0x05;}//
else {
atCmd4 = 0x04;}//
if ((Angle 0x2) == 0x2) { // ANGL[3:0] = [D6, D4, D2, D1]
atCmd3 = 0x05;}//
else {
atCmd3 = 0x04;}//
if ((Angle 0x1) == 0x1) { // ANGL[3:0] = [D6, D4, D2, D1]
atCmd2 = 0x05;}//
else {
atCmd2 = 0x04;}//
sendCmd(damp1Addr, D2, atCmd2,
sendCmd(damp1Addr, D4, atCmd4,
sendCmd(damp1Addr, D3, atCmd3,
sendCmd(damp1Addr, D6, atCmd6 //
ONLY PERFORM this
) ) ) )
function Callback() {sendCmd(damp1Addr, AC, 0 );} //apply changes
AND THIS
}
I have tried this in at least 5 or 6 different configuration and the
command only perform two of the calls the last in the bunch of 4 and the
last line of the function.
I am trying to send out packets to a wireless module through UART2 on the
BBB, and I will need 5 or more to be sent consecutively.
Thanks in advance for any help anyone can provide.

[beagleboard] BB Black and SSD1289 with 3.8

Re: [beagleboard] Re: PRU C Project - from device tree to program execution
*Okay, now i followed your Instructions with a clean new flashed Ubuntu 14.04 kernel 3.8.13 - aaand it works. :)* *I also can toggle some LED' s.* Well, if you were using a 3.14.x kernel, that would explain it. There is no capemgr in 3.14.x *Any idear where this diffrence comes from? Is the capemanagement that diffrent from Debian? I thought they were close relatives?!* Ubuntu is *based* on Debian. Debian uses SYSV init daemon where Ubuntu uses upstart. Starting with Jessie, it looks like Debian will be moving to systemd, and I've heard talk that Canonical is considering moving to systemd as well. Also, packages are somewhat different. Where Debian sticks with the tried and true approach, Ubuntu has a much more bleeding-edge package list. So, with Ubuntu you get newer packages, but sometimes at the cost of reliability. This is not to say that packages in Ubuntu are unstable / unreliable, they're just not tested as rigorously as is done in Debian. As to where your problem is coming from ? No idea, not enough information given. I'm guessing you were not using a 3.8.x kernel with Debian.

[beagleboard] Re: Issue getting DS18B20 temperature sensor working
Managed to get it all working with my DS18B20 in parasite mode, instead of
applying 3.3VDC I applied 5VDC though pin P9.7 and using a 1.5k resistor
instead of a 4.7k one.
If I applied the following resistors instead of the 1.5k ones I got the
following readings:
- 4.7k - t=85000
- 10k - t=127937

[beagleboard] make BBB Debian Hackerproof
Hey, I am using the BBB for backup (via BTSync, this also gives me some troubles lately, but that is a different story...). I am thinking of bringing the BBB to work (at a university) to get a real off-site backup. However, I am not sure what steps I should take in order to make sure nobody can access my files there. So my questions are: 1) What should I do to make sure it is secure? I think I would even be happy only to access it via USB and the webserver of BTsync (port ) 2) What services could I shut off? I don't need the GUI, the webserver, could probably lock down many ports and other services I do not even know that they are currently running... 3) Potentially I could also hook the BBB to my computer via USB and share Internet with it. Would that be a more secure option? Thanks Tommi Ps: I tried to search the group/internet, but interestingly it seems not to be a big question out there... -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] make BBB Debian Hackerproof
I been running a linux webserver in the wild open internet since 1996. if you keep your distro uptated and have a strong password you will be fine. remove packages you do not need to further secure your system.

[beagleboard] is power additive?
dear experts: quick hardware question: is power additive? that is, assume I have a 1A USB 5V adapter installed. if I now add a standard powered USB 2.0 connection (0.5A) to my (1A) USB 5V cable, does the BBB now have 1.5A? my hard drive shipped with a y-cable, that presumably helps it to draw 500mA*2. if I connect it to the BBB, can it draw 2A then?

Re: [beagleboard] eMMC flashing suggestions
here is a revised version of my mini-guide to using robert nelson's images for flashing/updating.it is a summary of the OS installation (upgrading) process. the information is already spread in many different places, but here is a summary (again) for the google cache: debian is the recommend distribution now. (not ubuntu, not angstrom, not others, even though they probably work, too.) yet, I found the official debian 7.5 standard releases to be too finicky. I always got something different and weird. half the time it would just blink to tell me that it would access both uSD and eMMC, half the time it would stop with all four LEDs black. sometimes it got stuck at its hdmi conversation. once or twice, I got a red-letter X screen telling me that it was flashing, but it never got far even then. in contrast, when I tried the new console flasher release, debian 7.7, I had instant success on both rev B and rev C boards. so, let me highly recommend 7.7. robert has posted images on both http://elinux.org/Beagleboard:BeagleBoneBlack_Debian and http://elinux.org/BeagleBoardDebian . you probably want the site with the colon in it. when you download images, make sure that your md5sum's are ok. a brief network interruption can lead you to endless tries due to a corrupt image file. the posted md5 is for the xz'ed version, not the unxz'ed img file. I recommend the lxde image, which you can find when you search for its md5sum, f93a8cdaec59a06198fbc9095320cc2d . in future month, just look for BBW/BBB (All Revs), Flasher: lxde: (xyzMb Free on 2GB eMMC). * on your linux laptop computer: download your chosen img.xz file, check the md5sum on the .img.xz file, use unxz on the image file, make sure that it is not mounted, and then burn-dd it. I recommend downloading the file into its own directory.: # umount /dev/mmcblk0p1 ## if it is mounted # unxz *.img.xz ## assuming it is the only such file in the directory # dd bs=1M if=*.img of=/dev/mmcblk0 # sync (where /dev/mmcblk0 is the flashable port to your uSD device location on your desktop or notebook). the dd should report that you copied about 1.8GB. on a $10 uSD premium 32gb card (300x), this takes about 90 seconds. then sync (just to make sure) before you remove it. I usually then remove and reinsert the disk to make sure that at least one linux partition shows up. if you do this, umount or eject it cleanly right after. on the bbb console images, there is only one partition, called rootfs, which is an ext4. on the lxde images, there are two partitions. again, make sure you umount these after your quick-test. * unpower your BBB. insert your burned uSD card in the BBB. you may need to hold the button near the card slot (though my BBBs seem to want to boot from the uSD slot by default), and power up the BBB. if the BBB does not power up, try pressing the power-on button and/or reset buttons where the four LEDs are. (after the flash, you may need to do this again, too, as power-insert by itself may not always start it.) * the USB power supply on a dual-head USB cable may or may not be enough. Robert recommends a 2A power supply. I have had luck with 1A. for flashing, I usually also remove the hdmi display and keyboard/mouse (and of course ethernet) to conserve power. I just have one cable, the power, to the BBB. * the display is active during the flash and can be connected to see the progress. it seems to work, even if you only have USB power to the BBB, but you have been warned that this is taking chances with power provision. * with a fast sdhc card, flashing the uSD image to the eMMC can take as little as 5-15 minutes. * during the flashing, the LEDs blink in a very succinct pattern back and forth. at the end, four solid LEDs means you succeeded. four black LEDs mean you failed. on the HDMI console, it will state when it has halted. * make sure to remove your uSD card NOW. otherwise, you may be reflashing again! * if you reboot, for the console images, you should see a nice penguin at the top left of the display. the boot should take about one minute in total. the default username (debian) and password (temppwd) are displayed on the hdmi login screen. however, root (without password) also works. NOTES * the USB gadget works out of the box on the lxde image 2014-11-19 (md5= f93a8cdae...). the USB gadget port comes alive pretty far towards the end of the boot. this means that when you boot up the BBB, on a connected PC, the BBB will show up as a 1d6b:0104 linux foundation multifunction composite gadget, which means that your connected PC will try to mount it like an external USB drive. also, the lxde image supports network connections into 192.168.7.2. all of this is without configuration and effort. * the USB gadget magic is not in the console images, as of nov 2014. as far as I can tell, the difference is that the
