2012-03-01 00:02 I should've answered: please change serial number of that defective device, to rule out something in driver fails on exactly that particular serial# 2012-03-01 00:04 "dear microsoft, we bought 500 workstations with win7. All are identical hw and same sw and config. one of those machines freezes screen after POST, while bios config works flawlessly. Please fix that bug in your OS!" 2012-03-01 00:06 ;-) 2012-03-01 00:07 but yes, serial numbers sometimes do matter. particularly if they're in some sort of ID PROM chip :) 2012-03-01 00:08 (sun used to have that. and we had one - at EPFL - that may have been flaky. of course, the heavy EMI from the experiments in the lab in the basement, right underneath the machine, didn't help) 2012-03-01 00:11 no, you should not connect the cut pin to GND. You should leave it NC, so user can connect it to GND or arbitrary other signal he likes, and replace the post with a new uncut one 2012-03-01 00:12 hmm. you mean to give more routing options ? 2012-03-01 00:14 yep 2012-03-01 00:14 no use in connecting GND to a not existing PIN when we already got 3 more GND lines 2012-03-01 00:14 pin 2012-03-01 00:17 hmm. making sure it's GND would enhance the barrier role on J21. but yes, that's admittedly not a strong argument. 2012-03-01 00:25 zenlunatic: I guess donating your time to work on it is better 2012-03-01 00:40 urandom__ has joined #qi-hardware 2012-03-01 00:53 cladamw has joined #qi-hardware 2012-03-01 01:25 xiangfu has joined #qi-hardware 2012-03-01 01:43 wej has joined #qi-hardware 2012-03-01 03:29 roh: about that cool p2p pager project 2012-03-01 03:29 :) 2012-03-01 03:30 802.15.4 cheap tranceiver is ... in $$$ ? 2012-03-01 03:30 i liked rfm12b-like modules they are less than 2usd last time i remenber 2012-03-01 03:30 i asume 802.15.4 is like starting from 5usd? 2012-03-01 03:31 btw you also mentioned cdc-ethernet 2012-03-01 03:31 does it out of the box (some how?) 2012-03-01 03:31 it was chips for something below 10E i think 2012-03-01 03:31 whole device below 20 2012-03-01 03:31 wouldt be cool just plug a nanonote to computer and get instant connectivity.. 2012-03-01 03:32 the mcu was 3$ or so 2012-03-01 03:32 i think we may share similar issues with cdc-ethernet :) 2012-03-01 03:32 sure. but its not for 'lots of ip' but rather 'send a sms through the jungle' 2012-03-01 03:32 really cheap mcu 2012-03-01 03:32 is nice, 2012-03-01 03:32 yeah. i need to get here here ;) 2012-03-01 03:32 for example i iamgine my nanonote, plug to computer and cdc-ethernet works of of the box then i get the message, beep ! 2012-03-01 03:33 beep and buzz ;) 2012-03-01 03:33 i asked her about how we could get it onto the nn, but we dont know yet 2012-03-01 03:33 all encrypted pager right on my device.. but network dont work that automatically 2012-03-01 03:33 yes, as you said it requires some routers infraestructure as well 2012-03-01 03:33 wolfspraul has joined #qi-hardware 2012-03-01 03:34 the nn doesnt do host-usb which would make it easier. but i think the stm32 should have enough pins so we can interface to spi too 2012-03-01 03:34 well !! invite her, no more to said, please share links blogs, etcc :) 2012-03-01 03:34 what is spi for in that case? 2012-03-01 03:34 to connect it to a ubb and the nn 2012-03-01 03:34 ok 2012-03-01 03:35 kristianpaul: very nice blog post from Artyom 2012-03-01 03:35 you also metioned 6Km, is not that too much power for unlicesed bands?

There are number of reasons why I had to refuse from ARM now. But before describing them I would mention that I don't exclude possibility to use it again in developing my current project. 2012-03-01 18:42 Reasons to switch to MM SoC: 2012-03-01 18:44 kilae has joined #qi-hardware 2012-03-01 18:45 1) Most commercial devices use one-chip solution. Couple of examples: Javad's Triumth chip (ASIC) is based on leon3+custom_cores. Namuru project uses single FPGA to run soft-cpu + altera's peripheral cores + famous_namuru_correlator. gnss-sensor also uses single FPGA to run custom gnss-core and leon3. 2012-03-01 18:45 Techical resons: 2012-03-01 18:46 LunaVorax has joined #qi-hardware 2012-03-01 18:46 LunaVorax has quit [#qi-hardware] 2012-03-01 18:47 2) ARM that I used for first experiments didn't allow to run namuru-core in FPGA and ARM on the same clock frequency. This is not only limitation of demo-board that I use but also limitation of ARM's interfaces. 2012-03-01 18:49 3) With ARM system I could use very limited memory (less then 100 kb) comparing to tens of Mb in MM SoC. Ohnestly speaking this is a limitation of the demo-board that I use. There is potential possibility to use external SDRAM-memory, but I don't know how fast it is for my tasks. 2012-03-01 18:52 4) It is easier to debug design with one chip then with two chips. I use less programmators. Reliaility of one-chip solution is higher. Price lower. 2012-03-01 18:56 5) For GPS/GNSS tasks FPGA is required in any way. There is no possibility to make correlator in ARM. (Ok, software solution is possible but that would be expensive solution which will require extra-difficult pcb design, soldering BGA-chips, solving signal-integrity issues and so on. That is why I don't consider software-correlator alternative ). So ability to refuse from ARM/DSP/any other... 2012-03-01 18:56 ...controller seems attractive. 2012-03-01 18:59 But as i mentioned I don't exclude possibility to use my board with ARM. But this is because I use rather "weak" FPGA (spartan3e500). 2012-03-01 19:05 kyak has joined #qi-hardware 2012-03-01 19:05 kyak has joined #qi-hardware 2012-03-01 19:10 And of coarse MM SoC also have weak sides: 2012-03-01 19:18 UART is very slow for my tasks, lm32 core is synthesised without cache for spartan3e wth xilinx soft. 2012-03-01 19:25 mstevens has joined #qi-hardware 2012-03-01 19:29 wpwrak: what do you think of this... 2012-03-01 19:29 once there was an STM32. it still works, except for one pin 2012-03-01 19:29 it's 3.6V 2012-03-01 19:29 and on that pin, a voltage of 15V was applied from a tantalum 10u cap 2012-03-01 19:30 if I'd pour 120% H2SO4 on it and examine it under a microscope, would I see a crater where the protection diode should have been? 2012-03-01 19:33 jekhor has joined #qi-hardware 2012-03-01 20:39 Artyom, had you compare you port with this https://github.com/fallen/milkymist-avnet ? 2012-03-01 20:39 perhaps there is a workaroud.. 2012-03-01 21:15 wolfspraul has joined #qi-hardware 2012-03-01 21:16 antgreen has joined #qi-hardware
