[beagleboard] Re: Accessing BeagleBoard features through Mono runtime on Ubuntu for C# development
What do you need / are you looking for exactly? You can certainly use the regular file system access to manipulate the GPIO, the serial ports, etc. This works fine. If you need access that is more direct than this, or higher performance, you'll probably have to develop it yourself. I don't think you are going to a BB API specifically designed for C#. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Stuck with applying the device tree overlay file (dtbo) On BeagleBoard-XM, any suggestions how?
Gilco, could you post the code you ended up using to get this to work? I am
in the same boat, I just want to use some GPIO pins for basic I/O but this
new device tree thing is making it hard. Cannot find any information on how
to simply export a few pins.
I would really appreciate any help!

A short question before I'll read and delve into more depth about the
subject:
I have noticed during the boot process, the beagleboard-xM (rev B)
prints on screen:
reading /dtbs/omap3-beagle-xm-ab.dtb
60695 bytes read in 13 ms (4.5 MiB/s)
## Error: expansion_args not defined
That's just an old variable in u-boot for the old board file boot. (the

## Flattened Device Tree blob at 815f

Starting kernel ..
So I searched for the omap3-beagle-xm-ab.dts (on linux_kernel-3.14.4
source) in order to modify it. but couldn't find it, found only
omap3-beagle-xm.dts
googled and found only this skinny file: omap3-beagle-xm-ab.dts, which
contains:
Yeah, just got merged to mainline a few weeks back.
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/omap3-beagle-xm-ab.dts?id=refs/tags/v3.15-rc5
/include/ omap3-beagle-xm.dts
/* On Rev A/B USBHOST_PWR_EN is active high */
hsusb2_power {
enable-active-high;
};
Is it the correct file? which I should:
1) modify
2) compile it to dtb
3) overwrite the exist file in /boot/uboot/dtbs/omap3-beagle-xm-ab.dtb
It's actually way easier to just decompile it with dtc, then recompile
it again.
dtc -I dtb -O dts omap3-beagle-xm-ab.dtb omap3-beagle-xm-ab.dts

Re: [beagleboard] Re: Beaglebone Black Ethernet Phy Not Detected on Boot.
When you see the repeating C's, I believe that is the ROM not finding u-boot. You have an issue with the mailbox drivers I use the following mailbox values for my kernel config CONFIG_MAILBOX=y # CONFIG_OMAP_MBOX is not set # CONFIG_OMAP2PLUS_MBOX is not set # CONFIG_OMAP_MBOX_KFIFO_SIZE is not set The davinci mdio driver should report a phymask and that value is used to update the device tree. I load the following drivers in the following order. libphy smsc davinci_cpdma davinci_mdio ti_cpsw I also remove the second phy slave from the device tree. I would verify your device tree blob has the correct values for your pin setup.

But, as it seems, this does not fix the issue completely. What I'm observing is lack of ethernet connection after some boots. They characterise with initial hangup, I can see 'C' being put on the console until a watchdog located on cape connected to my BBB reboots the BBB. It happens on its own, without any extraordinary operation being run on this system. For example two times last night. I have to plug out and in the power cable to fix the issue, SW reboot doesn't help. Power is delivered to BBB via our cape. Another way to reproduce it is to plug out the sd card and wait for watchdog to reboot BBB. After that, 'C' are printed to the console(OS on eMMC is not bootable), and when I insert back the sd it instantly boots from it. No connection after that too.

I do not use or need a dhcp server for my instructions, and am thinking a dhcp server is not necessary if you use static IP's. But I am not 100% sure where, or how uboot would get its IP from if you're loading it via network. Yes, if you set 'serverip' and 'ipaddr' you do not need to run dhcp once U-Boot is running. When AM335x SoCs boot from the network (which is the case for when it's a USB gadget device) a DHCP server _is_ required. Anyhow, having multiple dhcp servers on the same network can cause problems which may be difficult to trace down. Even if they are technically on different subnets, Hence why I do not use a BOOTP/DHCP server. This is not true, if you configure the dhcp server on your host correctly (which is to say, not to do anything on your normal eth interfaces and only look at the usb network device). -- Tom -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

When AM335x SoCs boot from the network (which is the case for when it's a USB gadget device) a DHCP server _is_ required. Anyhow, having multiple dhcp servers on the same network can cause problems which may be difficult to trace down. Even if they are technically on different subnets, Hence why I do not use a BOOTP/DHCP server.

[beagleboard] Hardware and Software Integration - Ethernet/LCD Modules To Drivers To Usage In Programs
Can anyone offer any insight into how this works? In general for all embedded dev you typically have hardware (for the sake of discussion lets say a Ethernet or LCD module), drivers for the specific hardware, a way to hook it into the OS if you are using one (or a graphics/windows library) and finally a way to call at a higher level methods to run the hardware. I received a 4D systems display with my beagleboard and it magically works. If I plug it into the headers on the board and power it on then the display works. If I disconnect it and use the onboard HDMI connector then magically the video shows up on my monitor. For Ethernet you can have a processor with an on-board MAC and external PHY or a module that uses SPI/Serial for example. Those are two very different methods of connecting Ethernet but magically in the demos for development boards it all works and you use libraries at a much higher level to create sockets, communicate, handle requests etc. While I have been able to find a lot regarding TCP/IP stacks, graphics libraries, and wiring diagrams for modules I have not been able to find much that explains this magic I did find that the board I have has a EEPROM on it that as part of the BeagleBoard firmware it will question what the cape is and wire up the driver to the display output (frame buffer?) I don't think this is necessarily specific to just the BeagleBone, since in development you are always trying to mix together hardware/modules/processors/Operating Systems/Bare Metal code. My question is there any good books/documentation/web sites/tutorials that show in more detail how you take a piece of hardware, a processer and optionally an operating system and get them working together? But more on the details of the magic and not hey look here is a LCD, plug it in here and write this python script and bam you got a picture? If I had a FPGA that implemented a MAC and had an external PHY and connected it to the Beaglebone Black or other processor running a TCP/IP stack how would I go about telling the OS or library this is the physical communication piece and here is the driver to run it? I know there has to be some hooks somewhere to connect the pieces it is just not clear where they are. On a PIC32 dev board I worked with you had to tell it which MAC/PHY driver you wanted to use by using #defines. It would include the code but I believe it was all a standard interface that each driver implemented. So the stack would just call methods/functions at the lowest level and this driver would do the actual sending/receiving of bits. There has to be a book(s) that explain the magic better. Correct me if I am wrong but the general concept is the same across all types of systems whether you are using Debian, a RTOS or a stack on bare metal. The higher level abstracts the hardware/functionality to an interface and you write the code for this interface so it communicates with whatever specific hardware/communication protocol you are using? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

I want to know what can be the issue, I'm powering it by the 5v pin not by usb, and I'm using latest update of angstrom in the official website from Beagelbone. I'm sure it is properly powered, since it looks is the most common trouble, and I'm using a 4gb SD card.

Re: [beagleboard] Is a Minimal install of Wheezy possible?

Can someone tell me if this is possible? I looked at Robert Nelson's page describing how to build a Tiny boot disk but am not sure I have either the knowledge or the hardware to do it. After it is all done, I plan to have the machine booting running from the SD card, at least for a while. Any help appreciated. https://github.com/RobertCNelson/netinstall This will boot debian's netinstall and allow you to setup the rootfs on either the mmc or external usb media.

Re: [beagleboard] SDcard is dead?
Now that I've had my morning coffee( long time ago , heh ), and read that persons instructions. I have to say there are many points of interest. Mostly, his / her instructions are all jacked up. From the looks of it this person was copying Roberts instructions from last year, with *many* deviations from Roberts original instructions. The lack of use of parted to set the boot partition active ( yes I saw that in fdisk but afaik that does not work in our case). fstab is also completely whack. Then last but not least, there is no mention of sudo in those instructions, for which I have to assume these instructions were performed as root. Bad mojo . . . Anyway, in your shoes I'd do as Robert suggests, follow his latest instructions, and you should not have any issues.

Re: [beagleboard] SDcard is dead?
Oh, and should I have mentioned that a journaling file system on a sd card is not exactly the best idea ?
