Re: [beagleboard] UWN-200 WiFi Dongle support in 3.14 kernels...

Exactly this. But, I have recently made good on my threat to acquire some TP-Link dongles, so I will try things out when I have a chance (traveling this week, so probably won't get to this for a week or so). I am having WLAN problems similar to yours in 3.14: freezes, having to manually bring up the link, etc. Wired links work fine. Did you make any progress? A couple of things I found along the way that might help you or others. I'd like to try my scenarios again with the latest 3.14 kernels using the TP-Link. Have you tried the latest and greatest? The latest 3.14 kernels, yes. https://groups.google.com/forum/#!category-topic/beagleboard/beaglebone-black/e7RVYNowOEQ Not sure I really care about anything any more besides the Atheros chip sets as everything else seems to be a huge waste of time. The TP-Link dongle I have is Ooopsing my kernel right now :-( snip Interesting. Guess I need to have a look at rfkill, thats a new one on me. So, are you thinking that in newer kernels (beyond 3.8), the default is to not obey the enable on boot stanzas in /etc/networking/interfaces? That additional stuff is needed? Can someone confirm or deny this assumption? Seems a bit odd that this is necessary, but I suppose it would explain the observed behavior. Has anyone else had this type of problem with enabling wireless interfaces in 3.14 kernels? What I do know is that my eth0 was completed commented out after I flashed my Bone with 3.14, yet the wired network interface came up without issue in /etc/network/interfaces. Now that I think about it, the image I flashed for Jessie contains lxqt, so maybe there is kind of tool working behind the scenes.

I feel your pain. snip Could this be something with the gateway config having changed in newer kernels? I can't remember whether I could get to the BBB via WiFi from a machine on the same subnet as I probably was SSHing to the BBB via a hardwired ethernet connection. It might be interesting to see if you can access the BBB via WiFi from a machine on the same subnet (without a hardwired ethernet connection) if you haven't already done so.

Am Montag, 10. November 2014 21:52:26 UTC+1 schrieb William Hermans: TJF, I'd be willing at some point to help you port some code for your project, Hello William, welcome at the libpruio project. I know about many tasks to improve the libpruio package. Some of them might be fun for you. Do you have a quick setup guide for your library ? Find the installation guide in the documentation at page Preparation http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/_cha_preparation.html . Could you check the documentation text? It seems that you're a native speaker with good language skills. You should be able to improve the text a lot. (I could mail a pdf version, where you could add your comments.) Other problem is that I am not exactly a hardware person so much as a software developer, and I am semi new to embedded Linux. The new to embeded Linux part shouldnt be too much of a problem, just means I need to read up on the libc functions available to me. Not being an EE however slows me down greatly however, since I do not want to fry my boards . . . I'm neither an electronics engineer, nor a programmer, nor an expert on embedded systems, nor a native speaker. I think I realy know what you're talking about. I'm looking at the project from the user point of view, evaluating how things should work and then do my best to make this happen. And, knowing there's no perfect solution, I try to learn from my failures. As an aside, I must have really really become accustomed to C over the last several years, BASIC syntax hurts my eyes, lol but it was the very first language I picked up 17+ years ago . . . Basic isn't the first programming language I used, but for me it's the most productive. I'm not speaking about the m$ dialects, which I dislike as well, and which I don't use since the middle 80's. (AFAIR QB 4.5 was the last one I tested and droped.) But there're other dialects, which are in some points more powerful than C, and easier to read for my old eyes. The libpruio package contains some examples, as you can see at this documentation page http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/_cha_examples.html. I think all code in folder src/c_examples could have a review. But most important, there're some examples with grafics output - pwm_adc.bas, - osci.bas, - rb_oszi.bas, and - triggers.bas which I didn't translate to C code jet. My idea was to use cairo grafics library, but there might be a more common way to create short and easy C code? Note: libpruio examples should be easy to understand for beginners and should have less than 200 lines of code. Feel free to send further colaboration ideas and discuss details (here or PM).

Re: [beagleboard] UWN-200 WiFi Dongle support in 3.14 kernels...
FWIW, I should note that my original problems were on a wheezy image. I switched back and forth between a 3.8 and a 3.14 kernel. My problems were all with the 3.14 kernel. I am not familiar with jessie as of yet. So, your problems may be modulated by that too besides the kernel. Does jessie use systemd? Does jessie use a different wireless configuration mechanism than wheezy? I suppose its time to do some research unless someone has already dealt with wireless configuration with jessie and cares to weigh in. ba -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

The whole point of config-pin and the universal cape was to be able to play with GPIO pins w/o needing to mess with device tree overlays. You can already use config-pin with the 3.14 kernel, most of the universal overlay is part of the default 3.14 device-tree by default (and you can add more of it in if necessary). -- Charles Steinkuehler char...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Thanks for the info Charles. I must have something wrong in my rebuild of the dtb file. I have no pin entries under /sys/class/gpio. I'll look around in /sys/kernel/debug/pinctl to see what the current config settings are. All my searches on this forum and the web turn up examples for the 3.8 kernel and cape manager. I've found references to configuring the GPIO pins under 3.14, but no examples or explainations of where changes can be verified. Cape Manager under 3.8 is documented very well. I found the repository for config-pin, but apt-cache search turned up nothing for installing it. Do I need to compile the source from the repo on the BBB to get config-pin?

Re: [beagleboard] Re: libpruio (fast and easy D/A - I/O)
Back in the early to mid 80's I was living in Kitzingen,Germany, and I was young. If you catch my meaning. But anyway, I am still a bit busy, but perhaps in my spare time I can read your documentation a bit at a time to be used to it. It is something I've been wanting to do for a while now . . .

November 2014 21:52:26 UTC+1 schrieb William Hermans: TJF, I'd be willing at some point to help you port some code for your project, Hello William, welcome at the libpruio project. I know about many tasks to improve the libpruio package. Some of them might be fun for you. Do you have a quick setup guide for your library ? Find the installation guide in the documentation at page Preparation http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/_cha_preparation.html . Could you check the documentation text? It seems that you're a native speaker with good language skills. You should be able to improve the text a lot. (I could mail a pdf version, where you could add your comments.) Other problem is that I am not exactly a hardware person so much as a software developer, and I am semi new to embedded Linux. The new to embeded Linux part shouldnt be too much of a problem, just means I need to read up on the libc functions available to me. Not being an EE however slows me down greatly however, since I do not want to fry my boards . . . I'm neither an electronics engineer, nor a programmer, nor an expert on embedded systems, nor a native speaker. I think I realy know what you're talking about. I'm looking at the project from the user point of view, evaluating how things should work and then do my best to make this happen. And, knowing there's no perfect solution, I try to learn from my failures. As an aside, I must have really really become accustomed to C over the last several years, BASIC syntax hurts my eyes, lol but it was the very first language I picked up 17+ years ago . . . Basic isn't the first programming language I used, but for me it's the most productive. I'm not speaking about the m$ dialects, which I dislike as well, and which I don't use since the middle 80's. (AFAIR QB 4.5 was the last one I tested and droped.) But there're other dialects, which are in some points more powerful than C, and easier to read for my old eyes. The libpruio package contains some examples, as you can see at this documentation page http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/_cha_examples.html. I think all code in folder src/c_examples could have a review. But most important, there're some examples with grafics output - pwm_adc.bas, - osci.bas, - rb_oszi.bas, and - triggers.bas which I didn't translate to C code jet. My idea was to use cairo grafics library, but there might be a more common way to create short and easy C code? Note: libpruio examples should be easy to understand for beginners and should have less than 200 lines of code. Feel free to send further colaboration ideas and discuss details (here or PM). Or just make your choice and start. BR -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Reccomended Development Linux
Good afternoon: I am getting ready to teach a class using the Beaglebone Black for a set of college students. Last year we were caught in the short supply of the black boards, so I'm getting started abit earlier. However, I'm trying to figure out the best distro and cross compilation environment to use. Last year I used a Ubuntu distro with the Debian image and while things went OK, there were some quirks. Based on feedback, I was planning on switching to a Debian distro, and I started building a VM for them to use for this purpose. However, it seems as if Debian is no longer including the gcc-arm-Linux-gnueabihf package, and many of the sites have indicated this is now obsolete. With that being the case, what is the current recommended cross compiler and platform for Beaglebone Black development?

Maxim, for distro's like Debian which is slow moving for stability reason. I would imagine the Debian team wants the technology proven before they make the leap. From what I understand, the next iteration of Debian *will* include systemd, and it is an apt-get-able package for wheezy right now. Also according to what I've read, it will work right along side SYSV, or at least init scripts, with no harm to anything, except perhaps slower boot times ( versus just using systemd by its self ). If you really want to know about it, I would suggest you do a bit of googling. There is lots of information out there about it, it is just that I have not been able to find a decent simple example of how to setup services yet. This is either because I'm not searching for the correct thing, or the documentation on the whole process is jut limited right now. The key point, is if Debian is going to move to using it, it is probably worth researching yourself.

From what I understand, the next iteration of Debian *will* include systemd, and it is an apt-get-able package for wheezy right now. Also according to what I've read, it will work right along side SYSV, or at least init scripts, with no harm to anything, except perhaps slower boot times ( versus just using systemd by its self ). If you really want to know about it, I would suggest you do a bit of googling. There is lots of information out there about it, it is just that I have not been able to find a decent simple example of how to setup services yet. This is either because I'm not searching for the correct thing, or the documentation on the whole process is jut limited right now. The key point, is if Debian is going to move to using it, it is probably worth researching yourself.

[beagleboard] Netinstall for Wheezy on Beagleboard xM
Hi all. I am trying to use Netinstall script, provided here https://github.com/RobertCNelson/netinstall ( Thanks to you, mr Robert C. Nelson, for the great job!). I managed to run just fine the installer but, when I am supposed to select a disk for install, I get no disk available. Don't know if I am getting something wrong here, but i wish I could create a SD card for my architecture with a bootable Debian wheezy. Up to the disk selection, everything run smoothly. What am I getting wrong? Thanks!

[beagleboard] Start working on a Project
Hi, I have worked on arduino and atmega16a before. In my past the only experience I have is in making a library for interfacing lcd jhd162a for atmega 16a. I have gone through the BBB manual. I will be getting BBB in 1 month. I have gone through the ideas of many projects listed on beagleboard.org, but since I am a newbie to BBB, I am not getting that from which project should I start contributing to. Till I get my BBB is there any way (theoretical or simulation) by which I start contributing to any project in beagleboard org? Is there any bug to be fixed to any project where I can start working and learn more about it and help in contributing. Please help. Looking forward to working with beagleboard org. -- 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: PRU0 base address
OK, solved, using this initialisation PRU is at least initialised:
HWREG(SOC_PRM_PER_REGS)|=0x0002;
HWREG(SOC_PRM_PER_REGS)|=0xFFFD;
HWREG(SOC_CM_PER_REGS+CM_PER_PRU_ICSS_CLKCTRL)=0x0002;
HWREG(SOC_CM_PER_REGS+CM_PER_PRU_ICSS_CLKSTCTRL)=(CM_PER_PRU_ICSS_CLKSTCTRL_OCP_GCLK|CM_PER_PRU_ICSS_CLKSTCTRL_IEP_GCLK);
memcpy((void*)PRU0IRAM_PHYS_BASE,textbuf,textlen);
memcpy((void*)DATARAM0_PHYS_BASE,databuf,datalen);
HWREG(PRU0CONTROL_PHYS_BASE+PRU_CTRL)=0x0002; // enable and execute
- PRUSS_CFG_BASE instead of PRU0CONTROL_PHYS_BASE?
Afterwards CTRL-register contains 0x8003 which means PRU is executing
something.

OK, seems I have to clarify this a bit: in my environment no Linux is
involved, I'm digging within the hardware directly.
What I found meanwhile: some clocks have to be enabled. But setting
CM_PER_PRU_ICSS_CLKCTRL to 0x0002 and CM_PER_PRU_ICSS_CLKSTCTRL to
0x0010 (=CM_PER_PRU_ICSS_CLKSTCTRL_OCP_GCLK) did not do the trick.
Any other ideas?

:
The PRU does need to be enabled, typically by a Device Tree entry similar
to this:
fragment@4 {
target = pruss;
__overlay__ {
status = okay;
};
};
If using a cape of some kind, this would normally be in the device tree
setup for that cape.
If it's your own custom cape, you would need to add this to your device
tree file.
There may also be a suitable device tree overlay already installed in
/lib/firmware that you can simply enable, but I don't have my BBB in front
of me right now to check.
