After that I was able to SSH in and I then changed the journaling settings

I updated to the 2013-05-02 image and I can't log in via ssh anymore.
At first I got the error:

I don't have any identity files on the client.
1) I tried ssh'ing into another machine and it works fine.
2) I then updated ssh with 'opkg update opkg upgrade' to a slightly
newer version (I forget the detailed version number, the last digit was
incremented...it reports Dropbear sshd v2012.55 on the command line).
3) I tried moving away my .ssh/know_hosts file on the client but I got
the same error.
4) I noticed when I '/etc/init.d/dropbear restart' that it seemed like it
never started because it couldn't be found when stopping.
*5) From looking at the script above (/etc/init.d/dropbear) it seems like
the identity file in /etc/dropbear/dropbear_rsa_host_key might be causing
the problem and the script recreates them if they don't exist. So I
removed it and started dropbear (/etc/init.d/dropbear start) again and it
generated new keys and then I could ssh in. It now works! (The side
effect of doing this is you also have to remove a line in the client's
~/.shh/know_hosts because the identity of the beaglebone has changed.)*

Re: [beagleboard] High(er) level language for PRU programming available.

So each “call” of a Forth function just took a single byte! The ARM/PRU combination is a perfect fit for a cross-compiled Forth. All of the compilation functions (“immediate words” in Forth) run on the ARM but lay down code in PRU-space. PRU-resident native code or lists of Forth function calls would just be the PRU application itself, plus the tiny bit of code needed to implement the Forth interpreter. Should be interesting to see what John has implemented. Your description is very close to the way it works. In this case it has 16-bit addresses so instructions cost 2 bytes. The compiler doesn't run on the ARM however. I considered that but it was far easier to implement it on the host computer. Among the reasons is that I would have had to implement a PRU assembler in Forth. Not too terribly difficult but still more work, and it would take up ARM program space. Against that I didn't see any advantage to having a full forth interpreter on the ARM. Most times a headerless forth is just fine on an embedded processor and that is the way I saw this project. (Sorry for the Forth jargon.) Didn't Robert put your Forth compiler into the latest release to run on the ARM anyway? The assembler was already there on the ARM. It would be great if you could check it. http://beagleboard.org/latest-images Before I started this I saw mentions of a C compiler but all the links appeared to be dead.

There are several BeagleBoards out there. Is this the BeagleBone Black? Vibration should not be an issue. Running it through a puddle of water? That would be an issue I would at least attempt to keep if from getting exposed to dirt as that can have conductive and corrosive material in it. Maybe a piece of plexiglass under the board.

[beagleboard] Re: beaglebone, PREEMPT-RT and low latency ADC/DAC
Hi all people here. I must to say im newbie in BB and RT data. So, im going to ask simple: I need to acquire in ADC of the BB in RT over 44khz, only read, i dont need to process it in RT is it possible to use the ADC of the BB to do it and DMA..? If it possible, can you show me some sample code to start with, or where to look at? (some link).. Really thanks El lunes, 10 de septiembre de 2012 07:29:55 UTC-4:30, Evan Thomas escribió: Hello, embedded/real time/hardware newbie here. I have an requirement to read an ADC, perform some simple FP calculations and write to DAC. It needs to be at least 20KHz but importantly the latency on the DAC/ADC needs to less than 10us. Low jitter is also important. Is the beaglebone up to it? I see this asked many times but not answered so I am not really expecting an answer now :) I have two specific questions 1) This might be naive but I thought I would try the PREEMPT_RT patch. In particular, I wanted to combine it with Robert Nelson's patches and build process. After many hours of random git commands, patch and modifying scripts I came to the conclusion that the current PREEMPT_RT patch is for 3.4 whereas Robert's patches are for 3.6. Firstly, does it even make sense to try PREEMPT_RT on BB? If so, what is the best way to proceed? Use 3.4 versions of Robert's patches and risk bugs and missing features? Wait for PREEMPT_RT patch against 3.6? 2) What is the best way to do low latency (10us) 14bit ADC and DAC on the BB? I assume it would have to be over the SPI bus, but beyond that I'm clueless. If someone can point me in the right direction I would really appreciate it.

Re: [beagleboard] Re: Implementation Board?
Capes are a key feature that we offer on this board. Much like what you see in PCs with the concept of plug in boards. If you have ever tried to remove a cape, you will know that these connections are indeed solid and reliable. I do not see an upside to removing that feature at this time. If you desire something different. I have donated hundreds of hours of engineering time to the community in the form of all the documentation and source files for this board. Feel free to modify it to your requirements and build the board you desire.

That sounds like a job a simple cape would do well -- the cape could have a larger size than the BBB board if you wanted to break out every signal. I'm sure there are eagle files available for the standard cape footprint -- you could very easily lay this out yourself hand have (e.g.) seeedstudio's PCB service fabricate it. The only minor disadvantages would be increased height (but put the screw terminals on the bottom of the cape if that's important), and an extra mechanical connection, which theoretically could affect reliability. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to a topic in the Google Groups BeagleBoard group.

Re: [beagleboard] Re: PRU Multiply and accumulate - how many cycles?
Hi, thanks for the reply. I also noticed something else which might be related: To synchronize both PRU's, one sends every 250 clock cycles some data with a command XOUT 10,r13,4 which the other receives via XIN 10,r13,4. This works well. If however i mismatch the registers, that is i combine XOUT 10,r13,4 on PRU0 with XIN 10,r14,4 on PRU1 th i still synchronize the two PRU's, even though I would expect both PRUs to simply stall here for 1024 cycles. Just thought this might be related to the other XIN/XOUT problems with the multiplier. 2014-04-16 18:36 GMT+02:00 Bas Laarhoven s...@xs4all.nl: On 16-4-2014 18:31, Lenny wrote: Hi, I started using the Multiply-and-Accumulate module of the PRU of my Beaglebone Black to construct a real-time digital filter.

I have observed other awkward behaviour of the Multiplier module, for example it only properly multiplied the values in registers r28 and r29 when I did a XOUT 0,r28,8 instruction before reading the result. Does someone have experience with this module? Is it possible that I am using it wrong, that it has to be activated properly before being usable, or that the hardware is not working correctly?

I thought I posted a similar message earlier today, but it has not showed up in the group (at least for me), so I am retrying. Today I downloaded and installed a fresh copy of the latest, 2014-04-14, Debian image. Previously I had been using your update scripts to update my installation to the latest version, but I noticed there wasn't an update script for this version when I did a git pull in the /opt/scripts directory. While using the new version I noticed that I had the same problems with my mouse pointer becoming invisible whenever I log out of LXDE, and the DPMS screen blanking being disabled, that I had reported earlier. To correct this I removed the ~/.xsessionrc file to get the default, On, state for the dpms screen blanking. I also had to add the following line to the end of the Device section of the /etc/X11/xorg.conf file. Without this line I had no mouse pointer at all. Option SWCursor true I now have a mouse pointer that remains visible across LXDE logout/login cycles, and my screen now turns off after 10 minutes of inactivity. I really think this a better default setup since the BBB behave like a standard desktop PC (I have a USB keyboard and mouse, and an HDMI monitor). New users will get correct and standard operation. More experienced users can change these behaviors if they need to (to disable screen blanking on a kiosk for example), especially if there are clear instructions on how to do so. While testing the changes to the ~/.xsessionrc file I notice that I am getting a ~/.xsession-errors file created on each reboot.

Re: [beagleboard] Re: beaglebone, PREEMPT-RT and low latency ADC/DAC
From http://processors.wiki.ti.com/index.php/AM335x_ADC_Driver%27s_Guide , ADC in AM335x can sample in 200KSPS(Kilo Samples Per Second) so 44K could be possible. However I think you have to do this with faster interface which means you cannot use sysfs; instead you have to use /dev/mem or PRU. I have very simple example of using ADC in these manner. 1. Using /dev/mem https://github.com/chunsj/nxctrl/blob/master/adc-test.c 2. Using PRU https://github.com/chunsj/nxctrl/blob/master/adcpru-test.p Though I'm not sure on your exact needs, I hope this can help you.

I have an requirement to read an ADC, perform some simple FP calculations and write to DAC. It needs to be at least 20KHz but importantly the latency on the DAC/ADC needs to less than 10us. Low jitter is also important. Is the beaglebone up to it? I see this asked many times but not answered so I am not really expecting an answer now :) I have two specific questions 1) This might be naive but I thought I would try the PREEMPT_RT patch. In particular, I wanted to combine it with Robert Nelson's patches and build process. After many hours of random git commands, patch and modifying scripts I came to the conclusion that the current PREEMPT_RT patch is for 3.4 whereas Robert's patches are for 3.6. Firstly, does it even make sense to try PREEMPT_RT on BB? If so, what is the best way to proceed? Use 3.4 versions of Robert's patches and risk bugs and missing features? Wait for PREEMPT_RT patch against 3.6? 2) What is the best way to do low latency (10us) 14bit ADC and DAC on the BB? I assume it would have to be over the SPI bus, but beyond that I'm clueless. If someone can point me in the right direction I would really appreciate it.

[beagleboard] Re: PRU Multiply and accumulate - how many cycles?
Thanks for the help Bas! I guess i found the problem: In my code, I used PRU0 simply as a timer with the code LOOP: WAIT(250 cycles) XOUT 14,r5,4 //transfer register r5 from PRU0 to PRU1 JMP LOOP In the meantime, PRU1 did some tasks, including multiplication using XOUT/XIN 0,r25,1 and similar instructions, and finally should have stalled at the instruction XIN 14,r5,4 in order to synchronize with PRU0. However, if the timing is initially not right, it can happen that PRU0 waits for the other PRU while blocking the XCHG port with its XOUT 14,... command. If now PRU1 wants to retrieve the result of a multiplication, e.g. execute XIN 0,r26,4, then it will wait until the XCHG port is liberated by PRU0, which itself will wait for maximally 1024 cycles if PRU1 accepts its XOUT request while keeping the port blocked, such that PRU1 can never get to that section in the code in time. In this case the two PRU's block each other and the programs runs about 1000 times slower! Also, the controls which are run to ensure a proper transfer through the XCHG port are quite basic: It seems to me that for a successful transfer between two PRUs, one only needs one PRU that is willing to write (launching XOUT 14,... ) and the other willing to read (XIN 14,...). The actual registers which are to be read or written, or the amount of data does not have to match between the two commands. If they dont match, I dont know what data is actually written, but at least none of the PRUs stalls for 1024 cycles. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Read() not returning after /dev/uioX is closed
Hi, I am rewriting a lot of the PRU app loader in go. Anyways, to wait for an interrupt one must read from /dev/uioX.

(in fact, I tried my code with other files and it worked just fine). Perhaps there's something I missed with the UIO docs or maybe its a kernel bug?

Re: [beagleboard] Re: Bad Linux ARM zImage magic
I have no hands on with this sort of thing, but I have noticed on many occations that we always need to research the hardware we use on a particular Linux Distro. .Which kernel are you using again ? 3.8.x does not do Hotplug very well, or even at all. SO if you're hot plugging USB devices into the hub after the system is up and running, It could be that the hub may buffer you from a kernel oops, but still does not recognize the devices. It could also be that you need to compile a module or two into the kernel statically for the HUB to work properly. But that is just a guess on my behalf that could be wrong. I have not personally noticed anything specific to this when browsing menuconfig, but I was not looking for this sort of thing when compiling my own kernel. *OR* Maybe you just need a different hub . . . Perhaps someone with more experience with this sort of thing will reply and give us their 2 cents.

Re: [beagleboard] ome problem when I get update
Did you generate locale data? For example, in arch linux (which I'm using), after configuration of /etc/locale.conf I should execute locale-gen so that configured locale data be generated.

Ok, I am not sure what you're doing there, but those nameservers do not match your ifconfig output. Try commenting out all of those atleast temporarily by adding a pound sign in front of ech statement ( # ) andthen add . . . nameserver 192.168.1.1 Just for kicks what do you have in /etc/network/interfaces ?

Re: [beagleboard] Unable to ping host machine
That gateway address should be wrong. That would be the network. 192.168.1.1 may be the gateway / nameserver, but i am not sure how your network is setup. How are your BBxM and host computer connected ? USBNET or ethernet ? IS there a router between the two systems or is teh BBxM connected directly to the host computer ? Host to me implies they are directly connected, but I do not remember if the xM has onboard ethernet or not.
