[beagleboard] Re: Beaglebone Black Wireless SDHC / SDXC support?

2018-12-26 Thread Bill Fleming
Any SD, SDHC, or SDXC should work on any BBB. As long as you don't try to use any "funny" cards such as the old non-standard 4 GB SD models, you shouldn't have any issues. Note that for programming and booting a full system image (with desktop interface) you really want an 8 GB or larger SDHC

I'm pretty sure that you can just always read the "value" inside the GPIO tree using a file read command. So for example if you try to set the pin a certain way and it didn't change (strong pull or short) the value read still reflects the actual state. So just write a C program using fopen and

Currently we use the following to set the timezone for when the BBB is connected to the internet, as the GUI tool doesn't work (or you don't have GUI anyway in some cases). This sets the US Central timezone as an example. cd /etc/ sudo rm localtime sudo ln -s /usr/share/zoneinfo/America/Chicago

[beagleboard] Getting "libEGL warning: DRI2: failed to authenticate" on all qt gui projects

2018-08-31 Thread Bill Fleming
On the Stretch LXQT Debian 9.4 image I am getting: "libEGL warning: DRI2: failed to authenticate" not just on my own simple widget qt apps but also on the included apps with lxqt. So after some searching it appears that mesa "updated" the libegl.so and libglesv2.so. However the instructions in

[beagleboard] How to force BBB to re-read EDID of new connected display?

2018-08-21 Thread Bill Fleming
On the Debian stretch images for BBB is there an easy way to force the EDID to update and/or the display to re-initialize such as if you change the connected display (while the BBB is still running)? I have noticed that I can switch to a different monitor on the HDMI, but

[beagleboard] How to fix bootup issues with barcode scanners and factory test code

2018-08-07 Thread Bill Fleming
If you are using Debian stretch with BeagleBone Black at least some of the images include test code that will run automatically when a barcode scanner is plugged in. (this was interesting to troubleshoot, lol) To my knowledge this was not present on any Debian 8.X LXQT images. You will know this

service when the pin is missing it stays missing. I still need to confirm in the application that the pin works correctly every time but this probably settles this issue. Later I can post up my scripts/service for reference once I get a final version. Bill On Monday, August 6, 2018 at 10:16:53 AM UTC-5
