| 00:01.32 | PwrSurge | hello |
| 00:02.04 | PwrSurge | i'm trying to develop an update process for my embedded device that preserves user settings |
| 00:02.13 | PwrSurge | and need a bit of help |
| 00:02.40 | PwrSurge | the issue i'm facing is that i'm running out of ram |
| 00:09.03 | roxfan | make a small bootloader/firmware update mode handler |
| 00:09.18 | roxfan | and use it to flash the blocks as they're sent |
| 00:47.40 | *** join/#edev djerome (~djerome@ip68-2-20-108.ph.ph.cox.net) |
| 00:58.04 | PwrSurge | want to try to avoid doing that |
| 00:58.16 | PwrSurge | my process now is: |
| 00:58.44 | PwrSurge | 1. download jffs2 image to mtd device |
| 00:59.15 | PwrSurge | 2. create mtdram device and mount the jffs2 image |
| 00:59.50 | PwrSurge | 3. copy the small user config files to the mounted jffs2 image |
| 01:00.16 | PwrSurge | 4. save the jffs2 image |
| 01:00.47 | PwrSurge | 5. with the jffs2 image on ramdisk, wipe the mtd partition |
| 01:01.04 | roxfan | what if something goes wrong? what if you lose power halfway? do you have any kind of recovery scenario? |
| 01:01.33 | PwrSurge | 6. flash the updated image on the mtd partition |
| 01:01.35 | PwrSurge | 7. reboot |
| 01:01.37 | roxfan | the more code you have running, the more room for errors |
| 01:01.48 | roxfan | fw update should be as simple as possible |
| 01:02.04 | PwrSurge | there is a built in recovery process on this device |
| 01:02.17 | PwrSurge | so it can be recovered if required |
| 01:02.21 | MonMotha | is there a reason you can't put the user settings on another mtd partition? |
| 01:02.40 | PwrSurge | it's a special partition that holds a recovery system |
| 01:03.18 | PwrSurge | and can be flashed to the main partition by flipping a switch to recovery in the back of the device |
| 01:03.24 | PwrSurge | works well |
| 01:03.39 | PwrSurge | so i'm not too worried about if something goes wrong |
| 01:04.19 | PwrSurge | by default, this system only has one active mtd partition at / |
| 01:04.28 | PwrSurge | and a ramfs partition at /tmp |
| 01:04.34 | PwrSurge | it sucks I know |
| 01:05.02 | PwrSurge | mtd partition is 81 MB |
| 01:05.35 | PwrSurge | tmp partition is 60MB but this can be changed |
| 01:05.54 | PwrSurge | issue is that i only have 128MB ram |
| 01:05.57 | PwrSurge | heh |
| 01:06.26 | PwrSurge | i'm experimenting with zram and it seems to help |
| 01:06.41 | PwrSurge | just need to figure out the right sizes so that i don't run out of space |

| 21:00.26 | landley | 95% of the traffic on #uclibc is the buildroot git-commit bot. |
| 21:18.18 | slashbeast | landley: yo, what's the status of toysh? |
| 21:26.24 | landley | slashbeast: poking at it a bit now. A ways away from being useful. |
| 21:26.50 | slashbeast | looks like latest update to dash breaks it badly |
| 21:27.07 | landley | The next big thing to do is add proper escape parsing, which includes " and ' quotes, $VARIABLES, $(subshells) (which have a nasty complex syntax), {curly,braces}, and so on. |
| 21:27.53 | landley | Did you notice that android includes a copy of ash in its core repo? |
| 21:28.02 | landley | Not busybox, the upstream bsd-licensed one. |
| 21:28.38 | landley | git clone https://android.googlesource.com/platform/system/core |
| 21:28.51 | slashbeast | there is upstream ash? |
| 21:29.01 | slashbeast | I thought it was created into bb |
| 21:29.05 | landley | I'm still writing my own, but if you need something in the short term, might be worth a look. |
| 21:29.19 | landley | slashbeast: nope. The upstream one is pretty sparse though. |
| 21:29.20 | slashbeast | already prepared ash from bb, but thanks |
| 21:29.33 | landley | busybox forked off its own version something like 10 years ago. |
| 21:29.39 | slashbeast | less than 100k, smaller than dash |
| 21:29.42 | landley | Back in the erik days, possibly before. |
| 21:29.59 | landley | Dash is the Defective Annoying SHell. If you were going to replace bash, there were already other options. :) |
| 21:30.54 | slashbeast | too late, but hey, the ask does work! ;p |
