[beagleboard] TIDL
Hi,
The TIDL examples written for OpenCV GUI output found at
(usr/share/ti/examples/tidl) function on the BeagleBone AI with image and
video inputs but does not function with camera input. Specifically I am
looking at the ssd_multibox demo which tidl-api documentation here states
should function with camera (live video) input (
http://downloads.ti.com/mctools/esd/docs/tidl-api/example.html)
debian@beaglebone:/usr/share/ti/examples/tidl/ssd_multibox$ sudo
./ssd_multibox -h
Usage: ssd_multibox
Will run partitioned ssd_multibox network to perform multi-objects
detection
and classification. First part of network (layersGroupId 1) runs on EVE,
second part (layersGroupId 2) runs on DSP.
Use -c to run a different segmentation network. Default is jdetnet_voc.
Optional arguments:
-c Valid configs: jdetnet_voc, jdetnet
-d Number of dsp cores to use
-e Number of eve cores to use
-iPath to the image file as input
Default are 9 frames in testvecs
* -i cameraUse camera as input*
* video input port: /dev/video*
-i .{mp4,mov,avi} Use video file as input
-l Path to the object classes list file
-f Number of frames to process
-w Output image/video width
-p Output probability threshold in percentage
Default is 25 percent or higher
-v Verbose output during execution
-h Help
I am executing demo on a monitor using a C1 Pro camera (
https://www.kurokesu.com/shop/CAMERA_C1_PRO) as input which has MJPG/YUYV
(video1) and h.264 (video2) output.
debian@beaglebone:/usr/share/ti/examples/tidl/ssd_multibox$ v4l2-ctl
--list-devices
vpe (platform:vpe):
/dev/video0
Kurokesu C1 PRO SN000163: Kurok (usb-xhci-hcd.1.auto-1.4):
/dev/video1
/dev/video2
Running the demo throws the following error (tried both video1/video2 with
same output):
debian@beaglebone:/usr/share/ti/examples/tidl/ssd_multibox$ sudo
./ssd_multibox -i /dev/video1
Input: /dev/video1
terminate called after throwing an instance of 'std::out_of_range'
what(): basic_string::substr: __pos (which is 140) > this->size() (which
is 0)
I understand this demo was initially written to run on the am572x evm with
camera module but I'd like to get it running on the Beaglebone AI in lieu
of the in progress mjpg-streamer version in cloud9
Any assistance would be much appreciated.
Thanks.
Rob

[beagleboard] Beaglebone Black new bwbasic-3.2a and relay cape program
4-16-2020 https://github.com/kenmartin-unix/Bwbasic-3.2a-for-BeagleBone Fully working Bwbasic-3.2a & relays.bas to test and operate and get the status of the relays on the cape. Note this version corrected issues with version 2.2 & 3.2 which is the version you get 2.2 if doing a sudo apt install bwbasic from the command line in Debian. When all done only two executable files are created. See READMEFIRST on GitHub Any issues open a new Issue in GitHub. Feedback is also welcome. This has been fully tested on the Beaglebone Black running Debian 9 & 10. This also works on other Linux platforms like Ubuntu, Raspberry, Linux Mint, Zorin OS, Linux Lite, etc. but no cape support of course. As a side after installing Bwbasic-3.2a checkout the BAS-EXAMPLES folder for examples of the many abilities of Bwbasic aside from working on relays. If you desire more info check out what's available in the INFO folder.

[beagleboard] connmanctl Wi-Fi automation
We are upgrading our product from the BeagleBone Black to BeagleBone Black Wireless and have had a really tough with automating a connection using connmanctl. In our current product's commissioning process, a customer logs into their BB via either USB or AP mode (which is hosting a wifi configuration page) and is able to enter their Wi-Fi SSID/password which is then passed onto a script to establish a connection with their network. The original implementation simply modified the /etc/network/interfaces file and with ifup/ifdown established a connection with their wireless network. However, we have had zero luck automating this connection using connmanctl as it launches an interactive shell which makes it impossible for scripts to enter user passwords. Any thoughts?? Started investigating /var/lib/connman/settings today but was hoping someone had success with this. Would hate to revert to our old method by uninstalling connmanctl..
