| 04:02.50 | CapnKernel | Can anyone help me work out the right args for mkfs.jffs2 for my NAND flash chip please? |
| 04:03.29 | CapnKernel | Micron 256MiB 16 bit part, kernel boot message says "NAND device: Manufacturer ID: 0x2c, Chip ID: 0xca (Micron NAND 256MiB 3,3V 16-bit)" |
| 04:05.09 | CapnKernel | u-boot "nand info" says "Device 0: NAND 256MiB 3,3V 16-bit, sector size 128 KiB" |
| 04:05.52 | CapnKernel | mkfs.jffs2 manpage says (of -e param): "If the SIZE specified is below 4096, the units are assumed to be KiB". |
| 04:06.53 | CapnKernel | Datasheet for NAND flash says "Page size x16: 1,056 words (1,024 + 32 words)" |
| 04:08.22 | CapnKernel | So I'm assuming I should use 2112 for the mkfs.jffs2 -s param. |
| 04:08.58 | CapnKernel | I.e., "mkfs.jffs2 -e 128 -l -s 2112" |
| 04:30.48 | CapnKernel | Kernel boot messages: http://www.pastebin.ca/1198873 |
| 04:31.23 | CapnKernel | I guess this means everyone's gone to sleep! :-) |
| 04:34.44 | Kmarc | I just wake up :) |
| 05:05.12 | CapnKernel | Haha, any ideas about jffs2 on nand flash? |

| 12:24.48 | shriram | Am using busybox - My kernel mounts the filesystem; init executes rcS and i get all the prints in rcs after which i dont get the shell prompt what could be wrong? |
| 12:28.13 | HcE | you forgot to tell Linux to put up som terminals? |
| 12:28.21 | HcE | how does your /etc/inittab look like? |
| 12:32.24 | shriram | HcE:http://pastebin.ca/1199083 |
| 12:32.49 | shriram | the filesystem works - i have tested it |
| 12:33.01 | shriram | but for somereason with the new kernel it does not |
| 12:33.37 | HcE | /dev/ttyS0 exists? |
| 12:33.42 | HcE | do you run mdev? |
| 12:33.50 | HcE | replaced hotplug with mdev in the kernel? |
| 12:34.00 | shriram | i dont have hotplug |
| 12:34.14 | HcE | oki, but the device nodes are correct? |
| 12:34.21 | HcE | (I would recomend using mdev...) |
| 12:34.33 | shriram | yes they are |
| 12:34.45 | HcE | then I have no clue |

| 12:37.06 | HcE | on my system |
| 12:37.20 | HcE | perhaps Busybox can be configured in a weird way to not enable console? |
| 12:37.53 | shriram | i dont know |

| 13:36.44 | pb_ | morning prpplague |
| 13:37.17 | prpplague | pb_: greetings |
| 13:37.29 | prpplague | pb_: whats cookin over on the other side of the pond? |
| 13:40.56 | pb_ | nothing much, just bracing myself for a meeting with our sales guys |
| 13:41.41 | prpplague | pb_: oh fun fun |
| 13:42.07 | pb_ | heh, indeed |
| 13:43.14 | prpplague | pb_: any cool hardware in the works? |
| 13:45.17 | pb_ | not a lot going on there right now. I'm sort of looking for an SDIO-interfaced wifi chip to use in one of our new designs but I haven't spent a lot of time on it yet. |
| 13:45.49 | prpplague | pb_: wanting to get it as a module or do your own? |
| 13:46.01 | pb_ | do our own, probably |
| 13:46.04 | prpplague | pb_: either way, give me a shout when you need some info |
| 13:46.11 | pb_ | ok, thanks |
| 13:46.16 | prpplague | pb_: the wi2wi stuff is really good |
| 13:46.26 | prpplague | pb_: works with the libertas driver in the main tree |
| 13:46.49 | prpplague | pb_: the only big item is you'll need to do your own antenna work |
| 13:47.24 | prpplague | pb_: we use several different sdio modules, give me a shout and i'll see if i can find some spares to send you |
| 13:47.34 | pb_ | cool |
| 13:47.43 | pb_ | any idea how much the wi2wi parts cost? |
| 13:48.02 | prpplague | checks his inventory |
| 13:48.27 | HcE | are there any tricks to mount a ext4 file system in Busybox? I enabled the support in the kernel, but I get -ENODEV from the kernel |

| 13:50.27 | prpplague | pb_: give me a minute or two to get that info, the inventory girl is on the phone |
| 13:50.50 | pb_ | sure, no rush. I will be here for another few hours yet :-} |
| 13:52.34 | prpplague | pb_: http://emwcs.avnet.com/webapp/wcs/stores/servlet/Product_-1_500201_500201_part_4294865732_6475334 |
| 13:52.44 | prpplague | pb_: there is some avnet pricing, but that seems high |
| 13:57.33 | pb_ | okay. that's definitely way more than I was hoping to pay. |
| 13:57.59 | prpplague | pb_: yea that seems pretty high |
| 13:58.20 | prpplague | pb_: most of the sdio modules are in the $28-$38 range |
| 13:58.33 | pb_ | we currently buy the usb 802.11 modules (complete units, assembled and tested) for less than $10, and any new solution needs to be competitive with that if it's going to be a winner for us. |
| 13:58.50 | prpplague | pb_: what type of interface? |
| 13:58.56 | pb_ | that's usb |
| 13:59.05 | prpplague | pb_: oem style? |
| 13:59.09 | pb_ | yeah |
| 13:59.21 | pb_ | basically the same thing as you'd get in retail, but minus the packaging |
| 14:00.03 | prpplague | ahh, yea, i think you are going to find that the sdio stuff is going for a pretty high price |
| 14:00.10 | pb_ | drat |
| 14:00.16 | pb_ | okay, sounds like we need to re-think our plan :-} |
| 14:00.18 | prpplague | we are actually considering moving our next gen stuff back to usb |
| 14:00.26 | pb_ | that's good information, thanks |
| 14:00.35 | prpplague | going with an oem module with 3.3v instead of a 5v |
| 14:01.07 | prpplague | pb_: our problem was battery life, the standard +5v usb modules were killing the battery way too quick |
| 14:01.08 | pb_ | meeting time now, bbiab |
| 14:01.13 | prpplague | pb_: good luck |
