[beagleboard] Can I get some help with getting started with the pocket beagle

[Tony Giaccone]

I thought I posted here once before but I don't see the posting or any 
replies so if this is a dup my apologies. 

I'm trying to set up a pocket beagle with my Mac and I can't seem to get 
USB networking up. 

When I connect the device to my mac is shows up on the networking tab as 
BeagleBone, and BeagleBone2. And I can ssh into the dvice. However as soon 
as I turn on network sharing everything blows up. The devices go from being 
useable network entries to one being "red" and the other going to a self 
assigned IP address.  The ssh connection is broken and the only recovery is 
to turn off shared networking and disconnect the cable and then reconnect 
it. 

I've made atempts on the board side to set up a default route.  And enable 
dhcp, which actually seems to be running already. If I try to ping from the 
pocket to the outside world it either fails to work or I get network 
unavailable. 

The mac is a macbook pro running sierra.  Any additional suggestions would 
be greatly appreciated.

[beagleboard] introduction

[Deepanshu]

hello everyone,

I am Deepanshu Gajbhiye. I am a 3rd-year computer science student. I would 
like to work in beagle board as my GSoC project. I have been working with 
hardware hacking and IOT for 3 months now. I have done firmware emulation, 
extraction of firmware, extracting sensitive information, etc. I have 
extensively worked  on kankun smart plug and found some new hacks with 
writing my own python script. 

Also for gsoc I studied all the beagleboards. Saw how to do network 
configuration on beagleboard black. I would love to contribute to this 
project.

I'm not clear - where are you turning on "network sharing" and *why*
are you turning it on?

Uninstall the horndis driver. The reason you are seeing two
interfaces, we have rndis for windows, and a cdc interface for mac.

By noise, do you mean analog background noise or digital related noise?

[beagleboard] Reading Image with Win32 Disk Imager - Why Does Boot Get Copied with Read Only Allocated Partitions

[Jeff Andich]

Hi,

I was needing a utility to read/clone an SD card without copying all of the 
additional wasted space on an SD card like the original Win32 Disk Imager 
Does.  From what I can tell, the latest Etcher for Windows only writes to 
SD card.

So I just tried the latest Win32 Disk Imager which now has a checkbox, 
"Read Only Allocated Partitions."  With the beaglebone/beagleboard images, 
I thought (in order to clone an SD card image without wasted space) for 
sure that with the structure of the BeagleBone/BeagleBoard images having a 
single ext4 partition and then MLO/u-boot in the "holes" below the 
partition somewhere, I would have to:

1) upload/read just the ext4 partition, clicking the Read Only Allocated 
Partition checkbox with Win32 Disk Imager
2) Write that uploaded partition to the target SD card.
3) Re-'dd' MLO and u-boot to the target SD card.

But low and behold, I tried booting my board after step #2, and it boots 
with my modified MLO..

Either Win32 Disk imager, when you click that checkbox, is reading from the 
start of the SD card to the end of the ext4 partition (and not reading past 
that point), or something else is going on. 

Why is the MLO/u-boot which reside in the "holes" copied as well?


Granted, I didn't google this in advance, so if this has already been 
discussed somewhere, then please don't answer...

Thanks!

Jeff

>From their readme:

"Read Only Allocated Partitions - Option to read only to the end of
the defined partition(s).  Ex:  Write a 2G image to a 32G device,
reading it to a new file will only read to the end of
the defined partition (2G)."

My guess, it starts from zero -> end of partition... Not the start of
the partition..

If your BCLK and WCLK are up the spout, then the CODEC will not be
synchronised to the audio stream and you'll get something that sounds
like static instead of the intended waveform.

Take a 16-bit signed PCM stereo audio file; and try playing it as 8-bit
unsigned PCM mono, and you'll get an idea of what I'm talking about.

Re: [beagleboard] Weird behaviour: input/output error and no commands after few minutes

[meglickib]

I have tried:
- 4 distinct power supplies (3 x 5V, 1x 12V)
- SD card and built in memory
- 3 different OS images 
-- latest 'iot' image from https://beagleboard.org/latest-images
-- image referenced in BeagleBoneBlue FAQ, 
https://debian.beagleboard.org/images/bone-debian-8.7-iot-armhf-2017-03-19-4gb.img.xz.
-- image referenced on Straswon Design,  
https://rcn-ee.com/rootfs/bb.org/testing/2017-03-07/iot/bone-debian-8.7-iot-armhf-2017-03-07-4gb.img.xz
 

Nothing helped. The input/output errors show usually after some writes to 
mmc and dmesg is flooded with errors.

I have also found on StrawsonDesign github this thread: 
https://github.com/StrawsonDesign/Robotics_Cape_Installer/issues/87 and 
StrawsonDesign mentioning that:

I've found this on about 10 out of 70 beaglebone blues, many of those 
> boards also show flash errors when running badblocks. I think it's a

In my case it also doesn't work with SD cards. I concluded that my BBBL is 
faulty and returned it.

Kind regards

>>>  2, Can I change MCLK frequences to 12 MHz while frame rate is 44,1 Khz?

Do you really mean 12 MHz? or 24 MHz?

Normally systems running 44.1 kHz frame rates use an MCLK of 
44.1 kHz *  256 = 11.2896 MHz, or,44.1 kHz *  512 =  22.5792 MHz

Re: [beagleboard] Re: Custom Board doesnt run with Angström Image

['Eric Schm.' via BeagleBoard]

I tried to build my own MLO and uboot.img with this commands:
- make CROSS_COMPILE=arm-linux-gnueabihf- distclean
- make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- 
am335x_boneblack_defconfig
- make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j4

I suppose that I have to build a custom MLO and uboot.img and put it on the 
boot partition. But after flashing the Debian Image9.3 I cant find a boot 
partition. And the only MLO and uboot.img I could find was under 
/opt/backup/uboot/
Could someone give an advise how I could boot the uboot?
