beaglebone black?
« on: September 01, 2013, 10:29:28 PM »
Hi

I just noticed the beaglebone black http://beagleboard.org/Products/BeagleBone%20Black board.
Processor: AM335x 1GHz ARM® Cortex-A8

Is microcore running on this board already?
The board is interesting because of the many connections including I2C audio out.
If it is possible to get microcore running I'm interested in getting involved in order to make microcore boot.

I second that. How are you guys coming along with an official release for this platform?
The memory mapping differs that of a x86-based of course. This ARM-based processor sports a 1GHz clk and would love to see it "full throttled" running TCL. :D

Despite it having 4GB, we all know the more, the better. ;)

As of right now I'm still awaiting mine to arrive but been extensively researching; finding documentation regarding it.
It will be a real treat (or compiled from scratch) To have TCL + a few choice utils manning this dev board.

Just recently I reviewed potencial targets for native Core with friends. We identified two potencial targets:

- Beaglebone Black
- OLinuXino

As they are both armv7 boards, they can share the same repo. Now as piCore 6.x development is going on I'm planning to port piCore 6.0 to armv7 reusing build scripts and development environment.

No dates, even no commitment it will happen, but is the plan today. Beaglebone Black delivery date is one, one and half month, but I can loan a board from a friend to start.

Regards... Bela

Mine finally came (USPS) and so did I :-\ :-X  after about 18hrs of pre-loaded Ångström+, tons of manuals, vids and beagleboard.org forums, in one day I'd say this is one of my best investments to date and should therefore meet or exceed my needs of it.

Seeing that it's all bga w/JTAG+ from here as long as I have access to 100% of it, I can't complain. Would like to benchmark GPIOs against specs to see how it does. Thus far it's humming along quite nicely, exceeding my expectations of it so I'm fine.  ;D

I'd reeeally like to TCL this thing, but for now I guess rc.d will do.
I have the RevB, for now, awaiting my RAMmy RevC's to arrive so I can post some goodies about it.

My experience is that Beaglbone Black (RevB) is much faster than Raspberry Pi. Building extensions takes significantly shorter time.

Debian is a bit ancient with GCC 4.6.3 and many old components, but works. Debian is not optimized for the BBB, GCC default target setting is not using NEON and builds for thumb mode so you do not get the real hw performance.

What is good, Raspberry Pi binaries work :)

I have now TC running on the Beagle Board Black accessed via SSH :)

 :o
I'd bet it's hella-faster.
I'm still configuring mine however I'll just cook me up a fresh arm and feed it to the B3 see what happens. Trying to break it :P.  I'm not much of a GUI fan either; I prefer ncurses. It works for what I need it for: SPEED.
Post your results :-\?

X will come later of course, but first is the normal Linux base :)

I'm rebuilding toolchain and core applications on BBB for ARM7. You can expect an alpha version next week.

Using the same piCore 6.0alpha version on both Raspberry Pi and Beaglebone Black the first impression how fast is the Beaglebone. Few adhoc figures, RPi / BBB:

xz decompression - 1.7 / 0.6 s
xz compression - 45.4 / 17.5 s
bcrypt build - 23.3 / 7 s
WAV to FLAC conversion - 42,2 / 31,0 s

Files were copied to RAM, so SD card access did not influence result

I ordered a BBB online yesterday at 3 P.M., arrived today just before 3 P.M. In the box I got not only BBB but an USB cable also. Connecting the USB cable in 10 seconds LXDE was up and running as well as its SSH and WEB servers. Debian is preinstalled in the internal 4GB flash, so don't have to waste time looking for USB cable, dowload op system, create SD card, etc. Just connect and you have it working. The USB slave port is not only for power but works as a network interface, so no need for Ethernet connection, you can connect via SSH, read docs with a browser, etc. In 10 seconds. Really nice.

Few mont ago I tested WBSDR on Raspberry Pi with FUNcube Dongle, which is a smart software defined receiver with 192 kbit/s I/Q audio. RPi was too slow. CPU was used 100% but it was not able to process signal realtime.

The same on Beaglebone Black works. CPU is 50-60% with single user on a noisy 2m band segment. APRS channel reception on 144.800 MHz looks OK both on screen and listening it:



Of corse running on Core 6.0 :)

Hello Bmarkus and others followers.

We look forward to using Core 6.0 with BBB! How long do you make it available for us, users?

Thanks ^^
