Re: [beagleboard] Re: Cannot see U-Boot# prompt in terminal

[Pavel Yermolenko]

Actually I have to start from scratch because as I mentioned before BBB 
fails to boot from eMMC and the SD card is empty.
Well I will once again regenerate the image in eMMC and once again format 
the SD card in ext4.
At this critical stage, I had an empty SD card, formatted in ext4 with a 
single "rootfs" partition.
So the next step (if my understanding is correct) was to create a *boot* 
partition on the SD card, where I could then transfer *MLO* and *u-boot.img*
.
You say I should edit *exlinux.conf*.
Ok i will do it as you suggest
And then?
What should I do with this *exlinux.conf* in order to create a *boot* 
partition on the SD card.
BTW execution of *generate_extlinux.sh* (which creates *exlinux.conf* on 
eMMC) corrupts eMMC: after execution of *generate_extlinux.sh* eMMC becomes 
"unbootable".

Re: [beagleboard] How to automatically set system time of BBB by external DS3231

[Niresh Kumar]

Hi,
I am a newbie to the linux environment and BBB, your information is very
helpful.

I've have tested both BB-I2C1-RTC-DS3231.dtbo and  BB-I2C2-RTC-DS3231.dtbo
 in the new image 4.19.94-ti-r42, they mount rtc1 in /dev but system time
is not updated with rtc1. Please let me know if any other procedure is
required and also procedure to update external rtc1 time when the internet
is connected.

One thing i have observed, with BB-I2C1-RTC-DS3231.dtbo the timedatectl
command displayed "RTC time: n/a" not system time as in normal condition.

Please clarify the following points
1.  How do you say the rtc chip is in i2c bus one. Using i2cdetect command
"i2cdetect -r 2" , 0x68 external device showed in i2c bus two.
2. I understand overlay is an out of  box approach. In 4.4.30-ti-r64,
system time updated with "echo ds3231 0x68 >
/sys/class/i2c-adapter/i2c-1/new_device; hwclock -r -f /dev/rtc1" in
/etc/rc.local.
Is there any problem if I use this approach in older images?

Regards,
NK

[beagleboard] Cool mikroBUS presentation at Linux Plumbers Conference!

[Jason Kridner]

See https://youtu.be/A3NyEjB5O38 for an early glimpse at the demo.

This will be presented at Linux Plumbers Conference on tomorrow, August
27th, by Vaishnav and is very much worth checking out.

Track information "You, Me, and IoT Two" microconference track:
https://linuxplumbersconf.org/event/7...

Latest RFC Patch: https://lore.kernel.org/patchwork/pat...

Instructions for Reproducing the Work:
https://github.com/vaishnav98/manifes...

For more information and discussions: https://elinux.org/Mikrobus


This was somewhat tipped on
https://www.phoronix.com/scan.php?page=news_item=MikroBUS-Linux-Driver-Patches
based on the LKML RFC, but it seems regular readers of Phoronix don't
really get what life is like for embedded Linux developers. This really is
a *big deal* and just part of what BeagleBoard is working on to greatly
simplify the life of "IoT" developers.

Stay tuned and check out the free live stream on YouTube!
https://www.youtube.com/c/LinuxPlumbersConference/videos

Also, be sure to check out the rest of the track (

It's the eMMC, use

root=/dev/mmcblk1p1

in extlinux.conf.

Now, that message is at

Re: [beagleboard] Re: Cannot see U-Boot# prompt in terminal

[Pavel Yermolenko]

I followed exactly your suggestions until generating *extlinux.conf*.
I don't understand why should I mount eMMC if I can access it directly ... 
as you mentioned in one of your previous mails it is generated in 
*/boot/extlinux/extlinux.conf*.
I could access it from my host via serial terminal or ssh.
How do I update it?
And then, once *extlinux.conf* updated, how do I use it ?

By the way, now I can't do anything because after all these manipulations 
BBB fails to boot from eMMC::

Re: [beagleboard] How to connect external power supply to BeagleBone AI?

[robert.sty...@gmail.com]

Looking at the A1 schematic 

Connect external 5V, + to P9.5 and P9.6 and - to P.9.1 and P9.2.
Diodes protect from connecting both cape and USB type C at the same time.

P9.1 P9.2 GND
P9.3 P9.4 VDD_3V3 output to Cape
P9.5 P9.6 VDD_CAPE_5V input to BBAI
P9.7 P9.8 VDD_5V output to Cape

There is a diode from VDD_CAPE_5V to VDD_5V
There is a MOSFET over-voltage breaker from TypeC_VBUS to VDD_TYPE C; and 
diode from VDD_TYPE C to VDD_5V

I have not looked at the BeagleBone AI, but I presume it has GPIO headers,
like the BeagleBoneBlack and the PocketBeagle. On both the BeagleBoneBlack and
PocketBeagle, there is a 5V supply pin -- P9-7 and P9-8 on the BeagleBoneBlack
and P1-1 on the PocketBeagle, which can be connected to a 5V supply.

Should be fine.  If it is like the BeagleBoneBlack or PocketBeagle the USB 
power and header Vin pins go to seperate pins on the power management chip, 
which takes care of selecting power sources, depending on what is available.

I don't understand either..

6 hours ago you had exactly that, but you didn't properly specify mmc
node name in the extlinux.conf file, so it failed on bootup.

I told you how to fix that, so why can't you fix /boot/extlinux/extlinux.conf ?

Once you fix /boot/extlinux/extlinux.conf so it boots today, you can
go ahead and install what ever version of mainline "u-boot" and it'll
just work..

Sorry, didn't understand.
My actual goal is to have sd-card with only two files *MLO *and *u-boot.img* 
in order to explore *u-boot* commands.
These two files are actually on host Ubuntu machine.
According to your previous message I don't see how can I get these files on 
sd-card.
Could you precise, please.

It's just a file in the Root File System.. Let me guess, it's on the the eMMC?

Just boot a simple console image:

https://elinux.org/Beagleboard:Latest-images-testing#Debian_10_.28Buster.29_Console

Mount the eMMC and update the file..

mkdir disk
sudo mount /dev/mmcblk1p1 ./disk/

Forgot to add, in all the "Buster" v4.19.x images, u-boot overlays is
enabled out of the box:

Re: [beagleboard] Re: Can't run Cloud9 IDE service on BBB

[Pavel Yermolenko]

Actually BBB is isn't connected to modem, but to the host (Ubuntu machine).
Several months ago I did some kind of Ethernet bridge for other card ... 
but I forgot how I did it.
Certainly this bridge works well with BBB because I could update/upgrade.

Hi Everyone,

So RC2 is now out, all the "wl18xx" based devices now have working
Bluetooth again, config: CONFIG_SERIAL_SC16IS7XX completely broke it..

I'm planning to do the "full" burn in testing this Saturday, my targets are:

Windows 10 (2004)
Debian
Mac OS (Mojave, Catalina)

Here is what i did last 'time' which took about a full day of none stop testing:

https://github.com/beagleboard/Latest-Images/issues/26

Please reply with more things to verify..

Now GSOC students, please reply with still un-merged patches and what
kernel they are targeting. I'd like to get all these projects built
and merged by this Thursday, then we can do a final "RC" next week,
that may turn into "FInal"..

[beagleboard] How to connect external power supply to BeagleBone AI?

[rr]

Hello,

With BeagleBone AI...
is it possible to use external power supply instead of powering from USB?

I would want to use it for a mobile application (Battery or LiPo). USB 
should be connected just for debug or update purposes.

1. If it possible at all to use external power supply? There is no 
connector on the board
2. If possible, is it possible to use USB, while external power supply is 
connected? Or would this cause a damage?

Thanks
Richard

That would be correct.

On your home network, you should have a firewall/WiFi/dhcp server that
was provided by your network provider, if you log into thait you
should be able to see every device connected in your home network..

Is it "right" IP ?

Normally, you would log into the device on your network that gives out
ip address's.

Is this 'your' network, or a University or Corporate network?

No, you can also use the "ip" your dhcp server gives it..  But that's
dependent on your network.

No nothing is corrupted, you imputed the wrong drive partition:

root=/dev/mmcblk0

While that is the microSD, you didn't specify the partition:

root=/dev/mmcblk0p1
or
root=/dev/mmcblk0p2

FOr the eMMC, it would be:

root=/dev/mmcblk1p1
root=/dev/mmcblk1p2

and so on..

aka, correctly input the drive/partition into
/boot/extlinux/extlinux.conf that you wish to use..

192.168.7.2/192.168.6.2  addresses are used when connected through the
usb interface..

How are you connected to the board?

Re: [beagleboard] Can't connect to BBB over Ethernet

[Steve Lentz]

This has nothing to do with the BBB, it’s your Ubuntu machine protecting you 
from something it thinks could be dangerous.  If you switch from one board to 
another, you will get this warning.  If you haven’t connected to a board in a 
long time (years), you may get it as well.  If you garble up SSH the first time 
you connect, it will give you this warning.  

Here’s a helpful link:

[beagleboard] Can't run Cloud9 IDE service on BBB

[Pavel Yermolenko]

Hello,

Connection time out while trying to access *Cloud9 IDE* service on BBB from 
host Ubuntu.
According to the "Explore BeagleBone" book, this address should work:

192.168.7.2:3000

But it doesn't.

Thanks in advance.

And this is repeated when I took out the SD card.
So, my attempt to boot from sd-card corrupted the image in eMMC ?

Re: [beagleboard] Re: Cannot see U-Boot# prompt in terminal

[Pavel Yermolenko]

Well ... I'm not sure I understood your suggestion correctly, but here's 
what I did:

   1. I didn't find generate_extlinux.sh 
   

 
   under /opt/scripts/tools/ on BBB, so I created it and edited 16th line
   2. Then I executed generate_extlinux.sh 
   

 
   (still on BBB)
   3. Then I changed for Ubuntu, where I copied MLO and u-boot.img in 
   rootfs on sd-card
   4. Then I've tried to boot from sd-card.

Here is what I got:
