| 23:59 | richardjortega | cool, i added a ticket issue to RVM to check for ntp on startup, otherwise the configure process hangs |
| 00:00 | tekk | i didn't come across that... mmm |
| 00:00 | tekk | isn't ntp in base-files ? |
| 00:04 | richardjortega | i'm not totally sure on that |
| 00:04 | richardjortega | i was working previously on Gunnar Wolf's debian distro |
| 00:04 | richardjortega | which is pretty bare |
| 00:05 | richardjortega | i didn't realize it until i ran it and then realized that system didn't have time |
| 00:06 | kgp_ | Question.... |
| 00:06 | richardjortega | he's the issue more specifically: https://github.com/wayneeseguin/rvm/issues/2966 |
| 00:07 | kgp_ | if every minute I transfer a file on the sdcard (image from a camera), transform this image, push this image on a remote server. |
| 00:07 | kgp_ | delete the image. |
| 00:07 | kgp_ | how long before the sd card dies. |
| 00:07 | richardjortega | lol |
| 00:08 | richardjortega | sorry i read that a little wrong, but rereading it, it sounds fine |
| 00:10 | richardjortega | i'm using it as server, reading/writing data every second, and logrotating/archiving the data weekly |
| 00:10 | kgp_ | and no dead sd card yet? |
| 00:11 | richardjortega | it's only been on that for two days |
| 00:11 | richardjortega | i except it not to die... otherwise this whole direction of making microcomputers would be for not |
| 00:12 | kgp_ | The life of SD Cards is limited but it could be a year or more on a Pi setup |
| 00:12 | kgp_ | On a forum |
| 00:13 | kgp_ | Most new flash memory is no less than 100,000 writes. Most of it is 1 million writes now. |
| 00:13 | kgp_ | Thats is actually untrue. Most flash cards today are in the range of 10k-1k rewrites (depends on the type of nand used) |
| 00:14 | richardjortega | mmm... I write each second and data is requested of me likewise |
| 00:14 | richardjortega | balls.... |
| 00:14 | kgp_ | write is different than read on flash memory. |
| 00:15 | kgp_ | I'll have 1'440 writes per day.... so I'll kill my card in 1-4 weeks.... |
| 00:15 | tekk | kgp_ i thought sd cards etc these days lasted around 3 years |
| 00:16 | kgp_ | if I don't do something clever like moving data around (like what you have on a ssd disk.) |
| 00:16 | kgp_ | yes... if you don't use them a lot tekk.... |
| 00:16 | richardjortega | kgp_: looked at probably same RPi post you pulled up, but an interesting topic is remaining space on SD disk as data can move there depending on algos and ish |
| 00:17 | kgp_ | yes ;) |
| 00:17 | tekk | so in reality, you recon our micro-sd's inside our cubox's will last a year? |
| 00:17 | kgp_ | if the algo is implemented... |
| 00:17 | tekk | i'm not pushing GB/day through it |
| 00:17 | tekk | and most hte data i push thorugh it never touches the disk |
| 00:17 | kgp_ | "Wear leveling" is what is used in SSD and usb flash drive. |
| 00:18 | kgp_ | but not on SD-card. |
| 00:18 | richardjortega | well i'll be pushing second writes like it was a server for a work project, will report back to community in a month or something... |
| 00:18 | richardjortega | then one day, a building will shut down and explode because it can't write |
| 00:18 | richardjortega | lol |
| 00:18 | deniska | kgp_: I believe it's used on some sd cards |
| 00:18 | deniska | If not, you may use jffs2 or similar fs |
| 00:19 | deniska | Which moves stuff around if a controller can't do that |
| 00:19 | kgp_ | or use a tmpfs |
| 00:20 | tekk | i flahsed that latest jessi btw |
| 00:20 | kgp_ | and? |
| 00:20 | tekk | its still runing kernel 3.0.35 and doesn't seem to have SPL u-boot |
| 00:20 | kgp_ | No success with my gnome install... |
| 00:21 | tekk | unless i'm mistaken |
| 00:21 | tekk | stil getting this: http://pasti.ng/p/YmzqNkrd |
| 00:21 | tekk | from cbxbiker61 's scripts |
| 00:22 | kgp_ | SanDisk SD cards have an endurance specification for each sector of 100,000 writes typical (reading a logical sector is unlimited). |
| 00:23 | tekk | if an sd card dies it goes read only right? |
| 00:23 | tekk | not the end of the world.... |
| 00:24 | tekk | just clone it to a new one and start again :D |
| 00:24 | kgp_ | expect if you run sometine in a customer... like a camera... |
| 00:25 | kgp_ | It's a service I want to build... and if I have to go around every 1-2 months... it's not really scalable. |
| 00:26 | kgp_ | Most decent SD cards use wear levelling algorithms to minimise the number of times each block is written, so if the SD card is bigger than you need the wear can be spread over a much larger area of free space. |
| 00:28 | kgp_ | That's actually a problem for some embedded projects. There's absolutely no way (apparently) to know what sectors might be wear leveled at any time, so a power cycle at the wrong time can destroy data anywhere on the card, no matter where you THINK you're writing. (don't ask how I know :) ) |
| 00:30 | kgp_ | Wear Leveling |
| 00:30 | kgp_ | Wear leveling is an intrinsic part of the erase pooling functionality of cards in the SanDisk SD |
| 00:30 | kgp_ | Card Product Family using NAND memory |
| 00:30 | kgp_ | http://media.digikey.com/pdf/Data%20Sheets/M-Systems%20Inc%20PDFs/SD%20Card%20Prod%20Family%20OEM%20Manual.pdf |
| 00:30 | kgp_ | good |
| 00:35 | cbxbiker61 | tekk, i should probably change the script to fail with error instead of defaulting to dove-cubox |
| 00:36 | cbxbiker61 | but if it's not SPL u-boot, it will will mis-identify |
| 00:43 | tekk | that was http://download.solid-run.com/pub/solidrun/cubox-i/Debian/Jessi-repackaged-trial/debian-jessi-4-july-2014.img.xz btw |
| 00:43 | tekk | which is supposed to be SPL u-boot |
| 00:44 | tekk | /boot contains uEnv.txt uImage |
| 00:45 | cbxbiker61 | spl u-boot installs will always have some .dtb files in /boot |
| 00:46 | tekk | ok, in that case its not an spl u-boot install |
| 00:46 | tekk | do you have an older kernel build and script that will work for non u-boot ? |
| 00:49 | cbxbiker61 | no, i only did .dtb based kernels, although I could use config_arm_appended_dbt, i do this for original cubox and sheevaplugs |
| 00:49 | cbxbiker61 | then you'd have to append the appropriate dtb to the end of the kernel |
| 00:50 | tekk | tekk> |
| 00:50 | tekk | does it use SPL u-boot now though? as last image didn't iirc |
| 00:50 | tekk | [10:14pm] |
| 00:50 | tekk | tekk: yes |
| 00:50 | tekk | [10:14pm] |
| 00:50 | tekk | sorry for that |
| 00:50 | tekk | [10:14pm] |
| 00:50 | tekk | great :) |
| 00:50 | tekk | [10:14pm] |
| 00:50 | tekk | that'll make it easier, i can use one of cbxbiker61 images |
| 00:50 | tekk | ;'( not true |
| 00:51 | rabeeh | cbxbiker61: spl u-boot supports both the older kernel 3.0.35 (uImage with machine ID) and the newer kernels with .dtbs |
| 00:52 | cbxbiker61 | oh, so we should be able to switch him over |
| 00:52 | cbxbiker61 | tekk you should be able to change the script to fix the identity to imx-imx, and it should work then |
| 00:53 | cbxbiker61 | cat /proc/cpuinfo for me, so i can fix it |
| 00:53 | tekk | http://pasti.ng/p/uaACwaVc |
| 00:53 | tekk | (pasti.ng is my own little project btw) :) |
| 00:54 | tekk | cbxbiker61, if i force the identity to imx-imx won't it build the wrong type of kernel? |
| 00:54 | cbxbiker61 | i'll post a modified script in just a sec |
| 00:55 | tekk | ah thanks |
| 00:55 | tekk | SET-IMX-KERNEL may/may not need changing too |
| 00:57 | kgp_ | tmpfs /tmp tmpfs defaults,noatime,nosuid,nodev,noexec,mode=1777,size=64M 0 0 |
| 00:57 | kgp_ | tmpfs /var/log tmpfs defaults,noatime,nosuid,nodev,noexec,mode=1777,size=64M 0 0 |
| 00:57 | kgp_ | in /etc/fstab could help me |
| 00:57 | tekk | noatime for sure |
| 00:58 | tekk | not sure about the others helping a great deal |
| 00:58 | kgp_ | yes I have it. |
| 00:58 | kgp_ | I'm doing some stuff on an image. |
| 00:58 | kgp_ | and it's ~10x faster. |
| 00:58 | tekk | :o |
| 00:59 | tekk | you'd have thought -noatime was default these days for distro's on flash |
| 00:59 | kgp_ | yes :) |
| 01:00 | cbxbiker61 | http://www.xilka.com/sheeva/tmp/UPDATE-KERNEL.sh , that should identify it as imx-imx, SET-IMX-KERNEL.sh doesn't need to be changed |
| 01:01 | tekk | right :) |
| 01:01 | tekk | gonna try in a sec |
| 01:01 | tekk | thanks |
| 01:04 | tekk | well its wget'ing |
| 01:04 | tekk | 3.10.49 |
| 01:05 | tekk | rebooting :) |
| 01:07 | tekk | hmm |
| 01:07 | tekk | it rebooted (quite quickly) |
| 01:07 | tekk | 3.0.35-g01c6ae1 |
| 01:07 | tekk | the fuuuck |
| 01:08 | kgp_ | quickly means? |
| 01:10 | kgp_ | I think I'm happy with my modifications ;) |
| 01:11 | kgp_ | bedtime |
| 01:14 | cbxbiker61 | tekk, you may have to move uImage out of the way, so it uses zImage |
| 01:15 | tekk | http://pasti.ng/p/ApUaAaHc |
| 01:15 | tekk | thats the contents of my /boot |
| 01:15 | tekk | after the kernel "upgrade" |
| 01:15 | tekk | should i rename imx-3.10.49-zImage to zImage ? or should it pick it up if i delete the uImage? |
| 01:17 | cbxbiker61 | put SET-IMX-KERNEL.sh in /boot and run sudo ./SET-IMX-KERNEL.sh 3.10.49 that links or copies zImage, then move uImage out of the way |
| 01:18 | tekk | i ran it outside of /boot last time |
| 01:18 | tekk | this time i get this: http://pasti.ng/p/mVvpgbpe |
| 01:19 | tekk | ( i am root ) |
| 01:19 | tekk | yet the files are created lol |
| 01:19 | tekk | zImage exists |
| 01:19 | tekk | gonna move uImage out the way and reboot |
| 01:24 | tekk | ok its not returning after reboot :( |
| 01:24 | tekk | im gonna continue tomorrow... super late hree |
| 01:31 | richardjortega | is there a tutorial on configuring wifi? |
| 01:31 | richardjortega | best to use /etc/network/interfaces or network-manager? i'll be setting this up to be non-desktop |
| 01:47 | richardjortega | any reason why a keyboard pipe button would return a ~ |
| 03:01 | mhoney | wrong keyboard type? |
| 03:01 | mhoney | I mean wrong localization |
| 16:02 | suihkulokki | what's the right DEBUG_LL_UART_x for original dove/cubox ? |
| 17:45 | rabeeh | suihkulokki: no idea |
| 17:45 | rabeeh | i don't recall that it worked |
| 17:58 | richardjortega | whoney: late response, yeah the recent debian release from rabeeh was UK keyboard. Yeah switching it over to US 101 helped me out thank |
| 22:58 | malte_ | rabeeh |
