**** BEGIN LOGGING AT Tue Oct 27 02:59:59 2015 Oct 27 03:53:18 is there a way to move some of the files onto a usb drive, and leave room on the eMMC for a swap and the important boot files and such? Oct 27 03:54:21 like move the /bin to the usb drive or sd card Oct 27 03:55:04 your example isn't a very good one, given that /bin contains rather essential executables :P Oct 27 03:55:42 and the answer is yes, you can, but it does need to be done carefully Oct 27 03:55:45 I am just shooting out an idea, I am not very savvy with linux but I am working on it. Oct 27 03:56:06 well step 1 would be to find out what is actually taking up all that space Oct 27 03:57:52 even if I just put the image on the 4gb eMMC and made a 1gb swap it would leave me with less then 500mb or so Oct 27 03:58:10 swap? Oct 27 03:58:11 o.O Oct 27 03:58:32 there are people who actually enable swap on an eMMC ? poor thing Oct 27 03:59:09 I want to use the emmc because of the speed. but I need the space for programs and just normal figuring out how everything works. Oct 27 03:59:23 if you insist on enabling swap, put *that* on an external card Oct 27 04:00:15 and I don't know why the standard image has so much crap on it either... I normally always start with a minimal console image and then install the packages I need Oct 27 04:00:17 I was just hoping the swap would help with the speed. I know they do it on ubuntu Oct 27 04:00:38 no, swap does not increase speed of anything on any system Oct 27 04:00:43 the problem is that I am just learning what I need now. Oct 27 04:01:00 and it sure as hell won't if you put swap on eMMC Oct 27 04:01:27 isn't a swap similar to a page file on windows for ram to unload? Oct 27 04:01:28 ok I should qualify my previous statement.. I guess swap *can* speed up a system under some circumstances Oct 27 04:02:00 by swapping out stuff that is idly taking up ram it can use more ram as disk cache Oct 27 04:02:20 right Oct 27 04:02:33 thats what I'm after lol I'm sry Oct 27 04:02:37 but eMMC is fast for reading and horribly slow for writing Oct 27 04:03:17 but I thought the eMMC was 2x or even father then the sd card or a flash drive Oct 27 04:03:31 faster* Oct 27 04:03:44 well, in theory it is, but that's the bus interface speed Oct 27 04:03:51 maybe you can max it out with reads Oct 27 04:03:54 definitely not with writes Oct 27 04:04:13 also, writes will wear out flash Oct 27 04:04:28 if you wear out a card or stick, you can replace it Oct 27 04:05:00 yeah but ill probably accidentally cook this on accident long before it would burn out the emmc Oct 27 04:05:17 still, enabling swap on eMMC is a bad idea Oct 27 04:05:33 I expect that enabling swap will be a net performance loss anyhow Oct 27 04:05:52 but I haven't tested it, so who knows Oct 27 04:06:04 how much faster is the emac vs the sd card? i see a lot of the new images are for sd cards Oct 27 04:06:29 I think rcn-ee always releases images for both? Oct 27 04:07:04 the bus interface is twice as fast (due to being 8-bit for eMMC vs 4-bit for SD) Oct 27 04:07:06 but Oct 27 04:07:12 could be, I may not have noticed it in the past. I put the BBB down for a couple years. Oct 27 04:07:17 actual speeds will depend on the flash chip spec Oct 27 04:08:05 on the BBB two different eMMC chips are used, kingston and micron, and they have quite different performance specs Oct 27 04:08:44 external μSD same story... especially write performance will vary a lot depending on the card you use Oct 27 04:08:45 I have kingston Oct 27 04:09:03 then you are lucky to have the fast eMMC Oct 27 04:11:10 I am just not sure of the proper way to approach the issue. I refresh my card sometimes a few times a day because just playing and trying new things will load up the eMMC Oct 27 04:11:24 reflash* Oct 27 04:11:57 ?! Oct 27 04:12:11 then figure out what's taking up all that space Oct 27 04:12:35 I am not at the point where I know what I need, so just trying different things to learn kind of kill me. Oct 27 04:15:41 I don't know linux very well, and I am learning to program to board also. so I know I am asking a lot of the board but I believe I will learn much more then on the raspberry pi. Oct 27 04:18:05 I'm trying to find a number of what the expected max number of writes per block is of flash nowadays, but can't immediately find it Oct 27 04:18:23 reflashing the whole eMMC multiple times per day is definitely not a good idea :P Oct 27 04:18:46 build a custom distro using yocto Oct 27 04:19:07 ds2: yeah that's definitely the easy road here for a linux newbie Oct 27 04:19:10 :P Oct 27 04:19:14 it is Oct 27 04:19:18 you don't know to know Linux Oct 27 04:19:28 download, edit file,bitbake,done. Oct 27 04:22:09 I just want to learn both linux/programming better/some electronics with this. I know it is not going to last forever but before I cook it they will probably have something new and better out. Oct 27 04:22:53 I am learning a lot already, I just want to try to smooth it out and make it a bit easier on me. Oct 27 04:25:59 I got pretty far with the arduino, I just feel like this is a good next step. Oct 27 04:46:20 do you think a usb flash drive or the sd card would be better to try this little swap experiment? Oct 27 04:47:47 I have a good sd card. so so usb sticks but I remember issues with the usb bus was adding a lot to the cpu on the raspberry pi Oct 27 07:03:58 help Oct 27 07:04:09 my self hiren Oct 27 07:04:35 at that time i am working on beagle borad blck Oct 27 07:04:59 how to battery status in beagle board black??? Oct 27 07:24:50 Hiren: the BBB doesn't have a battery by default Oct 27 09:45:23 (and the PMIC has no battery charge tracking) Oct 27 17:21:33 i am trying to send "TEST" to my /dev/ttyUSB0 device, using $cat > /dev/ttyUSB0 and pasting message works, but when i do echo -n "TEST" > /dev/ttyUSB0 it doesn't... something is different cause my USB device doesn't perform task with echo command, but does with cat command. Anyone have an idea? Oct 27 17:29:53 the redirection is the same ikn both cases .. suggest you look at the echo command Oct 27 17:30:31 you''ll probably find you have some issues with shell substitutions Oct 27 17:30:45 or interpretations, probably more accurately :) Oct 27 21:17:16 with computers everything is subject to interpretation :D Oct 27 23:03:18 Good morning :) BBB and Jessie snapshot, I'm find a lot of re-learning, and some holes compared to Wheezy Oct 27 23:10:15 Hmm, not many people about...signing off Oct 27 23:26:21 well true Oct 28 00:05:10 interesting, when I reboot my Linux (Arch on beagleboard xm) uboot doesn't initialize corretly. fails with spl_load_image_fat: error reading image u-boot.img, err - -1 Oct 28 00:05:40 full serial output http://vpaste.net/3KACm Oct 28 00:16:56 how did you create uboot.img ? and/or format your boot partition .. Oct 28 00:19:53 bad sd card? Oct 28 00:40:33 this happens on reboot. if I turn off and on the power it works again Oct 28 00:42:41 I didn't create uboot.img, it's installed by ArchLinux Oct 28 00:45:00 oh .. unknown source :p Oct 28 01:12:32 veremit: it's not so unknown, here's the recipe https://github.com/archlinuxarm/PKGBUILDs/tree/master/alarm/uboot-beagleboard Oct 28 01:12:48 also, should I repeat that it works just fine when powered on Oct 28 01:15:44 damjan .. shouldn't be any different on power-up to warm-boot .. theoretically .. Oct 28 01:16:02 unless there is a timing issue arising from shutdown on mmc /etc Oct 28 01:16:30 or some nuance of pmics .. we like them .. :/ not. Oct 28 01:42:30 you love PMICs they are very well documented too.. I have some nice beach front land in antartica you might like too Oct 28 01:45:30 only if you throw in ice breakers Oct 28 02:17:01 hmm beach+antarctica .. hmmm ... Oct 28 02:17:24 guessing their sand is .. very ... White .. Oct 28 02:17:37 and .. cold .. Oct 28 02:18:44 well some beaches are a bit iced over... but you can ignore it really ... sometimes. Oct 28 02:35:37 serious question for OpenEmbedded I don't see any designed with enlightenment just gnome (eww) xfce I suppose is ok. Any reason nothing for enlightenment or just biased? (joke really) **** ENDING LOGGING AT Wed Oct 28 02:59:58 2015
