What CAN transceiver are you using?  Have you verified your transceiver 
works?

Did you try using config-pin instead of the overlay?

See my post regarding a similar issue i had and see if it helps you:

I think there are screw holes in the heatsink for a 25 mm 1 inch fan, but 
no fan power socket, so no speed control.

I run a fan on my X15 from power on and it stays cool. I just received my
BBAI and I will build a fan support for it
also. I believe running cool gives quicker and better results.

This much drop on SYS_5V is certainly unexpected. Do you have some kind of 
load on it or just the probe?

BeagleBone AI should peak out about 1.8A (9W) under full 
processor/memory/flash load (including DSPs/EVEs/etc.). I don't know what 
your MacPro is outputing. 5W (1A) is much more typical.

I find something like 
https://www.amazon.com/Satechi-USB-C-Power-Tester-Multimeter/dp/B01MT8MC3N/ to 
be really useful for monitoring the current consumption and voltage.

Which port of your MacPro are you using and is it actively connected to a 
power source (not just battery)?

On BeagleBone AI, VDD_5V is input-to-BeagleBone-only, so the voltage really 
isn't of interest.

[beagleboard] BeagleBone AI - Severe thermal issues

2019-09-26 Thread Michael Zoran 
 I just got my BeagleBone AI today from mouser, and I'm noticing severe 
thermal issues even when the BeagleBone isn't doing much.
/sys/class/thermal is reporting over 100C within 10 minutes of the power 
being connected. 
At which point the safety features kick in and the power to the device gets 
shut off.

Is this normal???  Does the BeagleBone AI require a fan to be usable at all?

Also of interest is the free command is showing only 512MB of RAM instead 
of the 1GB it should. 
And the /proc file system is showing that a very generic device tree is 
being used.

This is an AI directly out of the box using only the preinstalled 
software.   I'm waiting for the serial debug cable to arrive that I ordered 
today
before I try reinstalling everything and maybe try lowering the clock speed.

Just thought this would be useful to other people.

[beagleboard] BeagleBone AI supported cameras

2019-09-26 Thread Dobrin Alexiev 


I bought one BeagleBone AI board to experiment with in my free time. 

I am thinking of running the demo described in: 
https://beagleboard.org/p/175809/tidl-on-beaglebone-ai-1ee263

 

I have two questions: 

1.  The demo uses the camera “Logitech HD Pro Webcam, C920, 1080p Lens”. Do 
I need to get exactly that camera? If no, is there a list of supported 
cameras for Beagle Bone AI and what do I need to change to use an 
alternative camera?

2. At the demo the board is setup with a fan. Is the fan optional at 23 C 
ambient temperature, or when the demo is running the board definitely needs 
it?

 

Thanks in advance.

Dobrin

[beagleboard] BeagleBone AI Overheat after SW Upgrade

2019-09-26 Thread Robert Forsyth 

Received AI yesterday (23-Sep-2019)

Followed the tethered start up

Connected to internet and upgraded.

After reboot and after a few minutes syslog produced a console message from 
kernel about critical temperature reached (80 C) and shutting down.

Any idea which linux image I should use?

[beagleboard] BB AI Voltages.

2019-09-26 Thread andrew . capon 
Hi Guys,

I am having some strange things going on with voltage levels and voltage drop.

First I noticed issues when powered from my MacPro, If I loaded the cpu then 
the board could reboot, it could also get in a state where it needed multiple 
reboots to get started.

So I connected up to a 2.5A USB supply and this issue goes away.

Another issue I am seeing though is I am only getting 4.6V on SYS_5V. I have 
connected a BBB to the same supply and see 5V on SYS_5V.

Also under cpu load SYS_5V drops to 4.3V.

When powered from the MacPro SYS_5V is 4.3V and drops to 4V under load and 
reboots. I tested a BBB connected to the MacPro and only get 4.7V on SYS_5V.

Also when connected to the power supply VDD_5V is only 2.16V.

Has anyone got any idea what might be going on here?

Many thanks

Andy

[beagleboard] Re: BBAI runs extremely hot

2019-09-26 Thread Myrick Monroe 
I had the same thermal problem and my board shut down by itself. I was able 
to solve this problem by placing an 80mm fan on top of the board. This fan 
has the usual 3 wires and I connected the red wire to 5V Sys (P9-7) and the 
black to GND in P9-1. The entire board now runs cool to the touch.

Sadly, with the AM5, we can't do the pinmux from userspace.. (hardware
bugs)...  Everything must be done early..

Thanks, that looks like it might work. I am a bit surprised though, that 
after the relative ease of use of config-pin and overlays, we should now be 
back at having to compile DTBs ourselves. I assume (hope) this is just 
temporary and in the future, there will be simpler solutions again.

It should work with any UVC, that's just one Jason has tested with..
If you look into the demo source code, i believe there is a frame
resize done, as the ti-tidl layer needs a specific frame size for
optimal stuff..

On the other hand, i think it would be useful to crowdsouce, which
camera's work and at what framerates, so if you have a usb/uvc camera
today, give a it a test. ;)

[beagleboard] cameras supported by BeagleBone AI TIDL demo

2019-09-26 Thread Dobrin Alexiev 


I am thinking of running the BeagleBone AI TIDL classification demo 
described in: https://beagleboard.org/p/175809/tidl-on-beaglebone-ai-1ee263

 

Two questions:

1.  The demo uses the camera “Logitech HD Pro Webcam, C920, 1080p Lens”. Do 
I need to get exactly that camera? If no, is there a list of supported 
cameras for Beagle Bone AI and what do I need to change to use an 
alternative camera?

2. At the demo the board is setup with a fan. Is the fan optional or when 
the demo is running the board definitely needs it?

[beagleboard] missing command in upgrade instructions?

2019-09-26 Thread jks 
The AI upgrade page asks for feedback (https://beagleboard.org/upgrade), so 
here's mine. Is there a command missing in the "update distribution 
components" section? After the "sudo apt update" you need a "sudo apt 
upgrade" (or dist-upgrade) to actually get and install the new packages, 
no? An "apt update" alone only refreshes the package index. When I did a 
dist-upgrade it worked as shown. All the other steps worked fine.

Connecting with ssh I found that out-of-the-box if I ran top or htop the

updating it increased to 9% (lol). A "killall lxqt-panel" put a stop to 
that and idle time returned to 99%. The GUI stuff shouldn't even be running

[beagleboard] Overlays as with BeagleBone Black

2019-09-26 Thread Bert Buchholz 
On the BeagleBone Black, I used the overlays defined in /boot/uEnv.txt to 
enable CAN and some UARTs and to disable several things like HDMI etc. Now 
I received my BBAI a few days ago where the whole overlay setup has been 
removed from uEnv.txt.

I then went ahead and tried to use the config-pin tool but for any pin I 
tried (I even tried to set some to GPIO) it errored out (I can't look up 
the error right now but could tomorrow, if it matters).

My question: How do I enable peripherals like CAN and UART (with or without 
overlays, it doesn't matter to me)?

I used the Debian 9.9 LXQT image 
(https://debian.beagleboard.org/images/am57xx-debian-9.9-lxqt-armhf-2019-08-03-4gb.img.xz)

Hi Robert, Installing was no problem, however I have trouble connecting to 
the board via SSH. After a power down, Cloud9 works, connecting via the 
debug connector works up to a point..

When connected via cloud9 I can create new terminals, but finding out about 
the network (ip addr) for example hangs the (remote/debug) terminal.

I've got a gist here with the serial debug output during startup: 
https://gist.github.com/luminize/9c747b83bbda4c589a0b516edb122b96
dmesg further periodically shows this:
