| 00:09.44 | ManoftheSea | I heard someone say TPM |
| 00:29.51 | ManoftheSea | And I caught up. |
| 00:30.05 | ManoftheSea | Do we dislike TPMs? TPMs are the protection for a computer at rest. |
| 00:30.14 | ManoftheSea | Protection from physical attack. |
| 00:50.12 | ManoftheSea | oh, who wants ops? |
| 00:50.28 | ManoftheSea | ah, luke has ops. Nevermind. |
| 01:13.48 | eduprey | ManoftheSea: heh, TPM is fine, I mean that the support for it is mandatory for microsoft to like an ARM platform, and it has to be impossible to replace windows 8 with Linux unless I misunderstood |
| 01:40.10 | lkcl | yes. microsoft's employees go round threatening companies that produce non-ms-capable laptops. |
| 01:41.25 | lkcl | whoops, you do x86 laptops? hmm, it's _so_ hard to compete when the cost of the license is $100 unlike everyone else who will be getting preferential rates, isn't it? |
| 02:05.36 | eduprey | lkcl: lol, "nice PC business you have there. shame if anything were to *happen* to it" |
| 02:06.01 | lkcl | ha ha so sue me, i ain't got nuffink to luuz |

| 03:54.52 | eduprey | Teclast P76Ti, is that RAM or Flash with the pins above the allwinner? probably flash? |
| 03:55.15 | eduprey | guessing the BGA chips next to the SoC are RAM |
| 04:05.12 | lkcl | eduprey: it's a 48-pin TSSOP. it's almost certainly NAND |
| 04:05.34 | lkcl | that's an 8-wire bus between the two. |
| 04:06.22 | lkcl | ... actually it's 13 wires :) |
| 04:06.34 | eduprey | lkcl: shame their RAM doesn't have pins, would be easier to rework than BGA :) |
| 04:07.29 | lkcl | A2Sheds: take a close look at that photo, see the wiggly lines? that's clock lines |

| 06:42.50 | A2Sheds | yup, it's lower cost than using 48 delay lines :) |
| 07:20.10 | A2Sheds | looks like BGA DDR3 to the right of the A10 and TSOP flash above |
| 07:21.23 | A2Sheds | http://android.sztupy.hu/teclast/dismantle/IMG_3415.JPG you can make out the part numbers in this photo |
| 08:10.00 | A2Sheds | rtems on ARM "the minimum system i had with rtems had 48k ram" |
| 09:58.26 | *** join/#arm-netbook gordan (~gordan@31.100.210.4) |
| 15:07.35 | A2Sheds | the rtems devs are looking over the stm32 openEC and libopencm3 to see how small a stm32 we can use and if there are any problems |
| 15:10.05 | A2Sheds | laptops have been getting away using 20Mhz 8051's with 2K sram, so we should be in pretty good shape with with 75-125MHz M3's with 64K |
| 15:29.23 | gordan | Might be a bit on the small side by today's standards... Oh wait - you don't mean for the main CPU. ;) |
| 15:43.59 | A2Sheds | heh, just for the EC |

| 17:11.21 | A2Sheds | http://www.sparkfun.com/products/9419 only $10! |
| 17:23.26 | A2Sheds | http://www.olimex.com/dev/arm-usb-ocd-h.html |
| 17:31.10 | mnemoc | the flyswatter is MUCH nicer |
| 17:31.40 | mnemoc | but we still miss a good way to get pins out of the micrsd slot |
| 17:38.09 | mnemoc | funny sparkfun... shipping that $10 sniffer to spain costs $40 to ship to spain using FedEx :D |
| 17:38.41 | mnemoc | $5 using regular airmail |
| 17:40.41 | A2Sheds | 3 weeks by airmail? |
| 17:41.04 | mnemoc | from US airmail takes "only" 10 days to my home |
| 17:41.22 | A2Sheds | not bad |
| 17:41.36 | A2Sheds | US to Australia is 3 weeks :( |
| 17:41.37 | mnemoc | A2Sheds: having those holes reachable, is it only a thing of connecting them with normal wires to the pins of the flyswatter or there is some extra electrical voodoo? |
| 17:41.56 | A2Sheds | let me check |
| 17:42.34 | A2Sheds | Supports target system voltages of: 3.3V, 2.5V, 1.8V, 1.5V, 1.2V (voltage range: 1.2V to 3.6V) |
| 17:42.46 | mnemoc | that's why I insist the alpha a10 eoma68 boards shall come with a custom breakout board |
| 17:43.38 | A2Sheds | the JTAG will also be on header for the protos |
| 17:44.12 | A2Sheds | we get it, make it solder free |
| 17:44.46 | A2Sheds | just like my motto "don't me me get out the compiler" |
| 17:44.55 | A2Sheds | make me |
| 17:45.14 | mnemoc | we also need access to the serial console |
| 17:45.34 | A2Sheds | yeah, it's all going to be there |
| 17:45.56 | mnemoc | ok |
| 17:46.06 | A2Sheds | <--- 12 years of coreboot |
| 17:46.31 | mnemoc | :) |
| 17:46.43 | A2Sheds | and a way to reflash firmware |
| 17:47.10 | mnemoc | jtag + openocd? |
| 17:47.43 | A2Sheds | I guess they didn't want to miss anything |
| 17:47.51 | mnemoc | :) |
| 17:48.02 | A2Sheds | we need to have all the signal available on headers to test everything out |
| 17:48.25 | mnemoc | have you seen the "trainer" board for beagle? |
| 17:48.41 | A2Sheds | we need to find out if there are software bugs as well as if there are hardware bugs |
| 17:48.52 | A2Sheds | i don't recall |
| 17:49.04 | mnemoc | http://www.tincantools.com/product.php?productid=16151&cat=255&page=1 |
| 17:49.23 | mnemoc | would it make sense to have something similar for eoma? |
| 17:49.56 | mnemoc | the only thing I can do with an iron is to burn my desk and fingers... but others may find it useful |
| 17:52.17 | A2Sheds | heh, and I'd rather hold the hot end of an iron that code :) |
| 17:52.26 | mnemoc | :D |
