it'd seem a little unfortunate that a 'custom' connector needs to be used, but 
i'd guess it can't really be helped given the high density
developing capes for it could be tough for a home hobbyist and i'd guess it 
could be rather expensive for commercial capes

[beagleboard] Pocket Beagle SPI1 ChipSelect on silkscreen is not CS0 but CS1

[Henner Zeller]

Hi,
Little heads-up: I just spent an hour or so to realize that the simple 'CS' 
(ChipSelect) printed on the silkscreen for SPI1 bus on the PocketBeagle is 
not CS0 as I expected, but CS1. So this is actually bus /dev/spidev2.1

Not sure if this was intended, but if it is, it should probably be marked 
on the silk-screen as CS1 to avoid future confusion; I can send a pull 
request for the board (in general, even CS0 should be marked as such)

If it is _not_ intended, the am335x-pocketbeagle.dts would need to be 
changed before capes start assuming this is CS1 (around line 389 Jason).

Cheers,
 Henner.

[beagleboard] Beaglebone Green Booting Issue

[vishnu . kn]

Hello all,
I am struggling with booting the beaglebone green from sd card. When beagle 
bone connected with custom carrier board then sysboot[15:14] state is 00b 
due to carrier board connections. There is no issue when booting from emmc.
MMC Clock frequency for different sysboot[15:14] are shown below.
MMC0 clock is 60MHz when sysboot[15:14]=00b 
MMC0 clock is 48MHz when sysboot[15:14]=01b
MMC1 clock is 48MHz in all conditions, and it is boot from emmc without any 
issue.
How can i solve this issue without changing my custom board connections.

Simple, you change your custom board connections..  This has been
documented in all the SRM's since the first BeagleBone (White) was
built..

Re: [beagleboard] x15 expansion connectors

[Jeff Andich]

Is there maybe any discussion on making a commercially-available breakout 
board for the X15's expansion header connectors?

So maybe the mating Hirose connector plugs into 1/4 expansion headers on 
the BB-X15 and attaches to a breadboard through a short ribbon cable?  


Just curious..

Thanks in adv!

HI Henner,

I've noticed this to while doing the overlays:

SPI1 CS1 is used as CS

https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/PB-SPI1-ETH-CLICK.dts#L83

SPI0 CS0 is used as CS

https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/PB-SPI0-ETH-CLICK.dts#L83

I haven't looked to closely, (just let my automated script setup the
pinmux's).. But if SPI1 (CS0) and SPI0 (CS1) is not on the header, we
should remove them from the base tree:

[beagleboard] Installing Basic Vision With A USB Webcam

[Timothy Litvin]

Building a custom mobile robotics platform, I’ve been monkeying with Linux, 
BeagleBone Blue and ArduPlane and Mission Planner for a few months. 
Communicating via wifi.  It’s been a rutted road, but I’ve gotten that 
portion to work.  I was greatly relieved to find a well-written beginner’s 
book dedicated to the BBBlue is now available, the *2nd edition of* *BeagleBone 
Robotics Projects*. 


Nevertheless, I’m stuck on what seems like should be a dirt-simple thing: 
viewing a webcam (Chapter 5). I’m using a Logitech C920 webcam, powered 
thru a USB hub (I’ve tried powering it direct-to-BB too). I can SSH in on 
wifi and I see /dev/video1 ...(not video0):


kimo@beaglebone:~$ cd /dev

and lsusb reports it:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

 

I’ve installed and started vncserver. I’ve installed guvcview, but it won’t 
start as it seems to be looking for a wrong configuration file in a 
non-existent directory:


kimo@beaglebone:/dev$ guvcview

GUVCVIEW: couldn't open /home/kimo/.config/guvcview2/video0 for read: No 
such file or directory

V4L2_CORE: ERROR opening V4L interface: No such file or directory

Unable to init server: Could not connect: Connection refused

GUVCVIEW: (GUI) Gtk3 can't open display

Guvcview error: no video device found


Of course, confirming on my Windows 10 machine, using TightVNC Viewer, 
->Applications menu->Multimedia->guvcview, it’s not finding my Logitech 
C920: “no device found”.

 

Pretty sure I followed the recipe by the book, and have checked it 
repeatedly. I need to borrow better eyes or a bigger brain.

*What did I miss? How do I tweak this?* Ultimately I want to run two or 
more USB cameras through OpenCV.  




Btw, proofreading, there’s a typo and font disparity on pp105 of the BBRP2E 
book, an executable command instructing us noobs to “make sure you start 
the server… by typing *VNC server* via SSH”, i.e., “vncserver”.)

[beagleboard] Questions on Image Builder

[Jeff Andich]

Hi,

I had a hard time finding a Debian Jessie console image (.img file) for 
both BB-X15 and BBB.  I eventually found that here,   
https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#Debian_Build_Instructions/
 
, but it seemed like LXQT images were more readily available. 

But if we needed a console image, it seemed like there were two options (1) 
do sudo apt-get remove on unnecessary packages or (2) use image builder. 

Regarding option 2, Image Builder.

1) Is Image Builder for everybody to use or mainly for Robert to generate 
BeagleBone/BeagleBoard images?  I saw an earlier thread (circa 2014) where 
Robert indicated that it was created mainly for him to use to generate 
images and referred to it as a "frankenscript."


2) Can Image Builder now run on a host Linux machine with the Linaro 
toolchain, for instance, or is it still intended to be run on an Armhf 
device?

This wiki from 2015 says build on ARMHF: 
https://elinux.org/BeagleBoneBlack_Rebuild_Debian_Image_Using_image-builder, 
"QEMU is un-reliable, thus no longer supported... Spend some Money and buy 
a real ARMHF device to run this script."


3) Is the procedure for generating images in image builder still as per 
https://elinux.org/BeagleBoneBlack_Rebuild_Debian_Image_Using_image-builder 
or is there an updated wiki now?


Thanks!!

Jeff

Like here?

https://elinux.org/Beagleboard:BeagleBoneBlack_Debian

Section 6.1.4.2

https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#microSD.2FStandalone:_.28console.29_.28BeagleBoard-X15.29

Yeah... it's a long list, i'd entertain ideas for how to better show that..

Yeah you can use it.. Just make sure to run it on arm..

./RootStock-NG.sh -c bb.org-debian-jessie-console-v4.4

Generates:

https://rcn-ee.net/rootfs/bb.org/testing/2017-10-02/console/debian-8.9-console-armhf-2017-10-02.tar.xz

and:

sudo ./setup_sdcard.sh --img-1gb
bbx15-debian-8.9-console-armhf-2017-10-02 --dtb am57xx-beagle-x15
--rootfs_label rootfs --hostname BeagleBoard-X15

Generates:

https://rcn-ee.net/rootfs/bb.org/testing/2017-10-02/console/bbx15-debian-8.9-console-armhf-2017-10-02-1gb.img.xz

If your goal is to fix QEMU, and your getting paid lots of money to do
it.. The script is a great "test" script to find broken things in
QEMU...

I just run this every week:

Thing is with all the images, there's really not "one" script...

I've split it into multiple "builds"...

[beagleboard] Device tree compiler throws error dtc: invalid option — '@'

[Mrigendra Chaubey]

Hi All,



I am trying to compile an overlay and use it for study purpose but I am not 
able to compile an overlay. For example I took an example device tree 
overlay from derek molloy blog

git clone git://github.com/derekmolloy/boneDeviceTree.git

and now I have a directory with a name overlay. In that a script *build* is 
there that have the compilation command for this overlay. this is the 
command inside build


*#!/bin/bash

echo "Compiling the overlay from .dts to .dtbo"

dtc -O dtb -o DM-GPIO-Test-00A0.dtbo -b 0 -@ DM-GPIO-Test.dts*
 

*DM-GPIO-Test.dts* file is the source overlay file and 
*DM-GPIO-Test-00A0.dtbo* is the output.

Now if I run this script I get this message




*./build
