[beagleboard] Re: RTC's SDA and SCL Resistors

There is lots of stuff going on, and it is messy. Check out this link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=785445 I tried the configuration via udev, but as reported in the above link, it doesn't work. Apparently the only way to get the /dev/rtc link to point to rtc1 instead of

[beagleboard] Re: RTC's SDA and SCL Resistors

Greg, it's okay. I was able to make the RTC be recognized as rtc1 in the system. Just turned off the BBB, disconnected everything that was connected to the hardware and starts again. I'm sure the RTC module was properly connected to the BBB, so I believe that there could only be some

[beagleboard] Re: RTC's SDA and SCL Resistors

Greg, I'd just like to prevent the RTC from being updated with the system date and time so that I can even use a script to do this task when I need to. How do I prevent the RTC from being updated automatically? Command response "timedatectl" root@beaglebone:~# timedatectl Local time: Fri

[beagleboard] Blue sagging power on GP0

I'm trying to wire an LED and 220 Ohm resistor to one of the GPIO pins on the *GP0* connector of the Blue. I measure 3.3V between the GND and 3.3V pins as I should, but

[beagleboard] Re: RTC's SDA and SCL Resistors

Only /dev/rtc0 is going to be updated automatically. /dev/rtc1 is not going to be updated automatically, as far as I can determine, with the Debian distributions as published. You would have to use the config tools to switch from rtc0 to rtc1 and compile a new kernel. So the common scheme you

[beagleboard] Re: RTC's SDA and SCL Resistors

Look at the link in /dev/rtc: ls -al | grep rtc If you got it to point at /dev/rtc1, I would very much like to know how you accomplished that! On Friday, July 28, 2017 at 10:09:19 AM UTC-4, William B wrote: > > Greg, it's okay. I was able to make the RTC be recognized as rtc1 in the > system.

[beagleboard] Re: Blue sagging power on GP0

I haven't gotten to attaching the LED and resistor across an GPIO pin. This is across the 3.3V power and GND. I hope the 12V supply can handle more than 20ma. --Mark evilwulfie | Fri 28-Jul-17 10:28 AM your LED is trying to use too much current. a IO pin can source 3ma you need very low

Re: [beagleboard] BB-SPIDEV1.dto conflict with univ-emmc on BBG

Hi Stefano, Do I understand that you were able to get SPI1.1 (P9_42) working? I can get SPI1.0 working with my BBB by disabling HDMI and loading BB-SPIDEV1 in uEnv.txt. This works with CS0, but this doesn't seem to allow me to use CS1. Any ideas? On Wednesday, June 29, 2016 at 8:54:18 AM
