| 00:23.04 | eduprey | lkcl: oh nice, should be possible to get it working on A10? |
| 00:23.19 | lkcl | it's for the stm32f |
| 00:24.30 | eduprey | ah ok,, so linux (a10) <-- SPI / I2C --> freertos (STM32) |
| 00:25.52 | eduprey | I know people have been talking about using STM32 in conjunction with the main SoC on EOMA board |
| 00:25.54 | eduprey | s |
| 00:26.31 | eduprey | (or I suppose more properly, on host boards that take EOMA's) |
| 00:28.36 | eduprey | and I suppose I2C over SPI since that's what we've got on the pinout |
| 00:38.58 | lkcl | yep. ah... no just I2C |
| 00:39.32 | lkcl | also turns out that the OLPC team had to redo the firmware (as GPL source code) for the XO-1 |
| 00:39.51 | lkcl | whiiich is entirely in c aaaand would save about 3 months of work. |
| 00:40.25 | lkcl | how can you _possibly_ have 13,000 lines of code just to operate the bloody hardware of a ... a... laptop for god's sake! |
| 00:40.53 | lkcl | anyway, it's there, and i'm kinda relieved it's been done already (although yeah it needs porting, obviously) |
| 00:47.07 | lkcl | http://wiki.laptop.org/go/OpenEC |
| 00:51.47 | mnemoc | lkcl: armv7m support? |
| 00:52.03 | lkcl | mnemoc: *clueless* |
| 00:53.12 | mnemoc | only one file not-c file ... http://dev.laptop.org/git/users/rsmith/ec-1.75/tree/ |
| 00:54.36 | eduprey | lkcl: yeah wrote that poorly I mean I2C chosen over SPI ie chosen instead of SPI :) |
| 00:54.53 | eduprey | since SPI doesn't exist |
| 00:56.55 | mnemoc | curses Google for dropping the + operator... |
| 01:02.14 | eduprey | lkcl: my day job was complaining because they have a few low power servers in an office closet but can't easily keep them cool.. so yeah, I definitely need to build them a 6x EOMA-CF board and wall mount it in there :) |
| 01:03.26 | eduprey | lkcl: are there any gigabit switch IC's that are sourceable by mere mortals? |
| 01:04.10 | mnemoc | eoma won't give you the bw you need for a server... |
| 01:04.34 | eduprey | mnemoc: think PC-class server, gigabit ethernet we have. |
| 01:05.24 | eduprey | its like a little workgroup for 10-15 people, a samba box and an openvpn server and a shell box |
| 01:06.02 | mnemoc | eduprey: if you can make each node live with one sata and 1gb of ram... |
| 01:06.15 | eduprey | mnemoc: can't see why not |
| 01:07.16 | mnemoc | :) |
| 01:09.39 | eduprey | though I guess we'll have some beefier cards in the future too |
| 01:10.16 | mnemoc | it's about the eoma interface... a card could have more ram in future |
| 01:10.37 | mnemoc | but you will still be limited to 1 usb, 1 sata and 1 ethernet.... and remote filesystems are junk |
| 01:11.01 | eduprey | yeah the interface isn't a problem, 1 sata channel and 1 usb and 1 gige per box is fine too |
| 01:11.20 | eduprey | there are sata multiplexers as long as you don't need a ton of IO |

| 13:37.56 | A2Sheds | lkcl: xvilka has worked with several of the rtos, we looked at freertos for ARM to replace closed BIOS code for EC's in notebooks and servers, but http://www.rtems.com/ has the most standards compliance |
| 13:38.42 | lkcl | yeayy |
| 13:38.49 | A2Sheds | most of my background has been with the closed RTOS like QNX and vxworks etc |
| 13:38.58 | A2Sheds | you guys decide |
| 13:39.53 | A2Sheds | RTEMS has a good size channel here #rtems |
| 13:40.59 | A2Sheds | and DrJoel there happily supports and ports it |
| 13:42.04 | A2Sheds | either one can be reduced to a few KB footprint |
| 13:53.44 | lkcl | ah! rtems was the one that i liked but couldn't find. |
| 14:01.18 | A2Sheds | bbl 8-core bulldozer + 970 MB for $199... must get |
