Re: [beagleboard] Pocket beagle not booting

[John Bacas]

I have used "*AM3358 Debian 10.3 2020-04-06 4GB SD IoT*"  image file and I 
used "*rufus 3.1*" to flash the image.
As I said, all 4 leds lighted up sequencially and after a while the user0 
led flashed like a heartbeat and user1 led kept flashing randomly.
That is normal as I have read, but still in my computer no device was 
detected.
After some unplugging and plugging, I used "*Etcher*" to flash the image.
Then I flashed some older images like "*Debian 9.9 2019-08-03 4GB SD IoT*" 
and   "*AM3358 Debian 10.0 2019-07-07 4GB SD IoT*" with "Etcher" too.
I have tried a different sd card but nothing changed.
Yesterday when I plugged Beagle in the usb port, an "RNDIS" message 
appeard but not any connection and only user0 led stays constantly lit.
User0 led is about kernel, so is there any damage inside the chip?

[beagleboard] Upgrading to Debian 10.7

[jose...@gmail.com]

Hi,

Debian has just released the 10.7 upgrade.
Doing an "apt update" followed by "apt list --upgradable"  in one of my 
BeagleBones, I found that there are a couple of systemd/udev upgrades 
sugested:

libnss-systemd/stable 241-7~deb10u5 armhf [upgradable from: 
241-7~deb10u4rcnee0~buster+20200509]
libpam-systemd/stable 241-7~deb10u5 armhf [upgradable from: 
241-7~deb10u4rcnee0~buster+20200509]
libsystemd0/stable 241-7~deb10u5 armhf [upgradable from: 
241-7~deb10u4rcnee0~buster+20200509]
libudev1/stable 241-7~deb10u5 armhf [upgradable from: 
241-7~deb10u4rcnee0~buster+20200509]
systemd-sysv/stable 241-7~deb10u5 armhf [upgradable from: 
241-7~deb10u4rcnee0~buster+20200509]
systemd/stable 241-7~deb10u5 armhf [upgradable from: 
241-7~deb10u4rcnee0~buster+20200509]
udev/stable 241-7~deb10u5 armhf [upgradable from: 
241-7~deb10u4rcnee0~buster+20200509]

Are these upgrades safe to perform?
My question arises because the BB's systemd packages are originally 
from repos.rcn-ee.com, so I supect they may have some BB specific tweeks.

Best regards,
José Gonçalves

Yeap this is still safe, the one "patch":

https://github.com/rcn-ee/repos/blob/master/debian-10-systemd/suite/buster/debian/patches/0001-units-add-usb-gadget-target.patch

Is still not fully utilized on the Beagle devices yet as those
libraries dependent on this feature are still under development and
not enabled. ;)

Re: [beagleboard] Pocket beagle not booting

[jonnymo]

If the LEDs are not blinking as expected, that does not sound good.  If you
have a FTDI cable, you could try to connect it to the PB as shown on the
following page to see if you get any messages related to the issue:
https://beagleboard.org/p/ken-shirriff/hands-on-with-the-pocketbeagle-a-25-linux-computer-606c66

I'm assuming you are not seeing a COM port active for the PB on your
Windows PC, correct?

Cheers,

Jon

Re: [beagleboard] Pocket beagle not booting

[John Bacas]

As I said I'm a newbie
Luckily I have an FTDI cable , but what software should I use as a console 
to read data from PB? I have Windows 10.

Actually, when I plug PB to my PC it makes the sound of connecting and a 
COM port appears in the Device Manager, but then another sound of 
disconnecting. This thing repeats for 10 times and finnaly the COM port 
disappears.
 Thnx

[beagleboard] DDD/GDB Error: no core file handler recognizes format

[rishabh . gupta777]

Hi,


I am working on the labs from ELC2018/Embedded Apprentice Linux Engineer 
. 
In the GDB Debugging Lab 2 
,
 
there are steps to generate a core dump file on the Pocket Beagle (I am 
using the BBBW) and analyze it on a host machine using DDD.

When I try to open the core file on my Ubuntu host, I get an error saying 
"no core file handler recognizes format". Since I was able to launch DDD 
with the Arm debugger (ddd --debugger arm-none-eabi-gdb), I think I have 
the necessary programs/packages installed on my host.

I would appreciate any inputs to resolve this issue.


Thanks,
Rishabh

Re: [beagleboard] Pocket beagle not booting

[jonnymo]

Note, I am not tech support. I'm just a guy trying to help you solve your
issue.

If you search for 'Windows 10 ftdi' you should find something that will
point you in the right direction.

This might help though.
https://learn.sparkfun.com/tutorials/terminal-basics/all

You can use something like TeraTerm, PuTTY or MobaXterm on Windows.  I
prefer PuTTY.

 That is normal as I have read, but still in my computer no device was

 After some unplugging and plugging, I used "*Etcher*" to flash the

 too.
 I have tried a different sd card but nothing changed.
 Yesterday when I plugged Beagle in the usb port, an "RNDIS" message 
 appeard but not any connection and only user0 led stays constantly lit.
 User0 led is about kernel, so is there any damage inside the chip?

 If the LEDs are not blinking as expected, that does not sound 
 good.  If you have a FTDI cable, you could try to connect it to the PB 
 as 
 shown on the following page to see if you get any messages related to 
 the 
 issue:

 https://beagleboard.org/p/ken-shirriff/hands-on-with-the-pocketbeagle-a-25-linux-computer-606c66

 I'm assuming you are not seeing a COM port active for the PB on 
 your Windows PC, correct?

 Cheers,

 Jon
