[beagleboard] Re: Update Kernel + Distro
The easiest way is (IMHO) this: 1. download the latest flasher image from here: http://beagleboard.org/latest-images (the Debian image is my strong recommendation -- Angstrom is an evolutionary dead-end) 2. place it on a MicroSD card 3. flash the BBB On Tuesday, July 1, 2014 2:13:36 AM UTC-7, leo mayer wrote: Hi, since my BBB runs for some time and I have now some spare time I thought I wanna udpate the kernel + distro.

Can I download some of the scripts which will then eventually perform the proper update? If so, which scripts?

Re: [beagleboard] Can't make UART work with Python and AdaFruitBBB
I don't understand your complaint. If you're using the Adafruit BBIO library, it creates the necessary UART devices in the device tree on the fly (by placing its own ADAFRUIT-UART files in /lib/firmware and writing to /sys/devices/bone_capmgr.*/slots). So it really is pretty easy to use -- it's designed for non-tech types to get maker projects running on the BBB. Surprised you asked over here rather than in the more-relevant Adafruit forum on BBIO.

So I probably will have to generate one that's correct ? These are the things people had to do when they will use UART in their systems? I believe that we could have a more prepared system for development ;) Anyway I'll try to look what can i do here Thank you all you help Robert Cláudio B. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: Dude, where's my BeagleBone Black?
Just as a note, we had our purchasing department price quantity 1,000 of the BBB using the Rev C. documents with a San-Diego-based company we already use for other PCBs in our products. They quoted us $128 per unit. So you can see that (a) the $55 for the Rev C board is quite a bargain (thank you, all), and (b) quantity and a willingness to make little or no profit have a huge impact on price. Really appreciate Beagleboard.org's willingness to create a great prototyping and maker tool. It's a hell of a little board. Thanks Gerald, Jason, TI, and all the others involved. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Where files per the Angstrom manual?
Completely agree with David. Angstrom seems to be a dead end, IMNSHO. On Wednesday, May 28, 2014 1:04:14 PM UTC-7, David Farning wrote: I would recommend that you upgrade your machines to the new Debian based release. I think you will find that there is more information about Debian than there is about Angstrom. The reason for the project moving from Angstrom to Debian is to allow developers to use Debian which is more common and better documented.

[beagleboard] Re: Where can I get the details of MII_RT ?
From http://e2e.ti.com/support/arm/sitara_arm/f/791/p/206939/733857.aspx *2. MII_RT is the real-time MII interface module inside PRU-ICSS. This is used for industrial communications such as EtherCAT. This is part of PRU-ICSS but has no relation to the Ethernet subsystem that is used for 10/100/1000 Mbps switching.PRU-ICSS is an independent module and MII_RT is a part of that. TI has chosen to not open it up for customer uses beyond what is supported by the SYS/BIOS based industrial SDK.* -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] Re: Developing for BeagleBone Black
Using Python -- along with the Adafruit BBIO Python library -- works quite well, and gives you all the development power of Python and associated native and third party libraries. Lighter weight than Java or C++, much higher level than C. I can't speak to Lua (no experience with it). Easy to get things running, and seems to run well under Angstrom. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
