Re: [Emc-users] Black BeagleBoard: available at $45 (was LinuxCNC would be very nice on the UDOO board.)
Hi, Just wondering which BBB to choose: $42 or $44 https://specialcomp.com/beaglebone/ I have the USB cable, but is it a problem that eMMC Storage is blank instead of Angstrom Distribution? On the other hand, Restricted Use for Feasibility Evaluation Only vs. Intended for Commercial Use - aren't the boards exactly the same? Then $42 looks preferable, doesn't it? What else should I buy? Acrylic Case might be useful, Power Supply?

2013/4/29 Kent A. Reed kentallanr...@gmail.com How much is your time worth? If the eMMC storage is blank you'll need to download an image file, burn it to a microSD card, plug it in, and boot from it (the BBB Angstrom distribution automagically transfers itself to the eMMC storage; Robert Nelson provides a script one can use, or at least work from, to accomplish the same thing with other builds). It's your call: pay the man the $2 or do the time. My board is naked at the moment but, lord willing and the creek don't rise, I'll have it mounted on standoffs from some sort of plate by tonight as I've done for previous SoCs I've played with. Encasements will come later when I've decided how I'm going to be using them. You can power the BBB from the microUSB port but things may get dicey if you're going to hang power-sucking USB peripherals from the other port. I like to use a decent 5v power supply. (I have a collection left over from various defunct products). Thanks a lot! It's not about time, it's about fun! I suspected that transferring the boot image is no problem, just was not sure. Then $42 it is. And no power supply, I can find something in my inventory. Also, I hope to use remote desktop instead of monitor (when Ubuntu is installed).

If it handles those fine, then I'm ready to get excited about it. This is a problem that has been around for some time. it is almost certainly more complicated than at first glance. Oh, one other data point. I have been using SanDisk 4gb SD cards, with relatively few problems. I have a Dane-Elec disk that croaked after minimal usage, and doesn't seem to be repaired by fsck. A number of other users also report good luck with official SanDisk and some other name-brand cards, and a lot of problems with off-brand or cards that might be counterfeit, bought on eBay or whatever. I bought many of my SD cards at MicroCenter. If the power is shut off while the SD card is in the middle of a wear-leveling swap, I don't know how it will handle that. There are methods of keeping all data in a secure condition until the swap is complete, but some cheap controllers may not have firmware that does this right. If the wear-leveling remap table gets corrupted, the card is generally scrap, there's no way to reformat it. I remember having problems with my brand new BeagleBoardXM not booting Arch Linux from specific microSD cards, instead throwing an mmc time-out error. The first one to fail was a SanDisk card with proper specifications but the problem seemed to be a function of manufacturing tolerance or some other hidden variable and not of the specific manufacturer. There was lots of forum traffic (stretching back to 2009!), lots of handwaving and kernel developers kept adding defensive code to the driver and suggesting different kernel configuration parameters. The offending cards seemed to work with other distributions including the Angstrom distribution of the time. As I said in a Feb 2012 ArchLinux forum message, there doesn't seem to be any consistency to the implementations of the fixes in various distributions. The offending cards also seemed to work with other boards which suggested to me the problem may be exacerbated by the nature of the BeagleBoardXM's physical interface to the microSD card. I never felt comfortable with microSD card technology after that. The rampant counterfeiting doesn't help either---but that wasn't the source of my problem. I'm not reading all the forums I used to and this problem you're discussing has caught me completely by surprise. It makes me even more uncomfortable. I wonder if the built-in flash memory of the new BeagleBone Black can have this problem too? That would be a nasty surprise.

I think when I pick up a couple of these this summer, I will try incorporating an ultracapacitor-based UPS that can hold up power for the ten seconds required for a true shutdown, along with powerfail detection to initiate the shutdown.

You might look at changing your distribution if a shutdown on the pi is taking that long.

This is a problem that has been around for some time. it is almost certainly more complicated than at first glance. it may be some kind of interaction between the writes to the SD card and the wear leveling algorithm in the card. Apparently, some people have been running for years with no trouble, and others have SD cards become completely unusable within weeks. i have a couple units in the field with the original Beagle Board, and have had some minor trouble with corrupted SD cards, but my fix is to plug them into a desktop PC with card reader and do an fsck on them. That has always brought them back. Our units run in an industrial equipment rack and are powered on and off willy-nilly by the users, and nobody in the field has reported a dead one, yet. If you read the R Pi and Beagle discussion lists, there is a LOT of traffic about this problem. I have been using ext3 and noatime settings on the fstab, which seem to help. some people report ext4 has some kind of serious interaction that kills SD cards (it isn't supposed to...)
