| 14:56.36 | kerio | DocScrutinizer05: will openbsd run on the neo900? |
| 14:59.01 | DocScrutinizer05 | sure, why not? |
| 14:59.15 | DocScrutinizer05 | does openBSD run on beagleboard? |
| 14:59.31 | kerio | yes |
| 14:59.36 | kerio | http://www.openbsd.org/armv7.html a very small handful of boards |
| 14:59.40 | DocScrutinizer05 | so, there's your answer |
| 14:59.45 | kerio | yay ^_^ |
| 15:00.35 | kerio | ...is the neo900 just a beagleboard that you guys scrunched up to fit in the n900 case? ¬.¬ |
| 15:00.36 | DocScrutinizer05 | we even use BB-xM for "emu" in proto_v2 |
| 15:00.54 | DocScrutinizer05 | sort of, plus we added tons of peripherals |
| 15:01.10 | DocScrutinizer05 | btw same applies for N900 |
| 15:01.17 | DocScrutinizer05 | and for GTA04 |
| 15:01.41 | kerio | hm, is there any arm board with pcie 3.0 |
| 15:01.52 | DocScrutinizer05 | dunno of any |
| 15:02.06 | DocScrutinizer05 | maybe OMAP5 has such stuff |
| 15:02.52 | DocScrutinizer05 | seems it has SATA, so why not PCIE3 |
| 15:03.08 | DocScrutinizer05 | never closely looked into it |
| 15:03.53 | kerio | will http://www.intel.com/content/www/us/en/solid-state-drives/solid-state-drives-750-series.html work with the neo900 |
| 15:04.07 | kerio | it would add quite a lot of very fast swap |
| 15:04.16 | DocScrutinizer05 | honestly now, you tell us :-) |
| 15:05.23 | kerio | no arm board supports any of those fancy connectors :( |
| 15:05.27 | kerio | no nvme, no m.2 |
| 15:05.28 | DocScrutinizer05 | you got USB2.0 and UART as fast interfaces |
| 15:05.42 | kerio | """fast""" |
| 15:06.14 | DocScrutinizer05 | well, 480Mbit is already at the limits of the complete system |
| 15:06.51 | DocScrutinizer05 | I mean, you not only need to transfer data, you also need to *do* sth with it |
| 15:07.48 | DocScrutinizer05 | when you can't even transfer it to RAM anymore then your bottleneck is elsewhere, not in bandwidth of interface |
| 15:08.39 | kerio | just overclock the shit out of the ram |
| 15:08.41 | kerio | ez |
| 15:08.51 | DocScrutinizer05 | well, the RAM is still a tad faster than USB2 I think, but not like magnitudes faster |
| 15:08.58 | kerio | wait, really? |
| 15:08.59 | kerio | :o |
| 15:09.53 | kerio | fast unbuffered ram can reach 20GB/s |
| 15:10.01 | kerio | (ddr3 on intel) |
| 15:10.15 | DocScrutinizer05 | with a OMAP3? dream on |
| 15:10.26 | kerio | weirdly enough, the best ddr4 is slower than that |
| 15:10.45 | DocScrutinizer05 | we got LPDDR2-133 iirc |
| 15:11.15 | DocScrutinizer05 | maybe even -200 |
| 15:11.55 | DocScrutinizer05 | if my math doesn't suck due to lack of caffeine, that's still just 4 times the speed of USB2.0, roughly |
| 15:12.52 | DocScrutinizer05 | and you need to handle the IO too, which needs to get done in CPU land, either in sw or at least by DMA |
| 15:15.04 | DocScrutinizer05 | I could be wrong by factor2 or even 4, with my math |
| 15:15.15 | DocScrutinizer05 | still... you get the picture |
| 15:15.50 | kerio | ye ye |
| 15:15.54 | kerio | i was only mostly kidding |
| 15:17.37 | kerio | is still looking for a ram-based, volatile microsd |
| 15:19.53 | DocScrutinizer05 | holler if you find any, would be a really nice device indeed |
| 15:24.42 | DocScrutinizer05 | anyway on OMAP3 iirc the SDcard interface is limited to 48Mhz clock and, for uSD, 4 bit bus width, which makes 24MB/s in my book |
| 15:25.54 | DocScrutinizer05 | eMMC has 8bit bus, thus twice that |
| 15:26.17 | DocScrutinizer05 | so it's somewhat on par with USB2.0 |
| 15:26.33 | kerio | ...i didn't realize that the uSD was that slow |
| 15:28.48 | ceene | is the ram on n900 replaceable? |
| 15:29.08 | *** join/#maemo liujian0012hn (~liu@42.49.144.223) |
| 15:31.03 | DocScrutinizer05 | plainly no |
| 15:31.38 | ceene | can't the chip be unsoldered and replaced? |
| 15:31.39 | DocScrutinizer05 | some tried it, I never heard again from any of them |
| 15:32.20 | DocScrutinizer05 | we did something similar on beagleboard-xM to test our 1GB RAM |
| 15:32.56 | DocScrutinizer05 | which took highly sophisitcated rework station and experienced personal to get accomplished |
| 15:33.30 | ceene | is it bga or something like that? |
| 15:33.49 | DocScrutinizer05 | and we swapped the complete SoC/RAM&NAND PoP stack |
| 15:33.57 | DocScrutinizer05 | it's PoP |
| 15:34.02 | kerio | DocScrutinizer05: yeah but can you clean the fans of my macbook pro? |
| 15:34.32 | DocScrutinizer05 | yes, I'll use pressurized air and kill your macbook ;-P |
| 15:34.49 | kerio | https://www.ifixit.com/Device/MacBook_Pro_15%22_Retina_Display_Late_2013 |
| 15:34.52 | kerio | Repairability: 1 / 10 |
| 15:34.53 | DocScrutinizer05 | I did so with other notebooks before |
| 15:35.08 | kerio | i cleaned my mom's non-retina macbook, it was very very easy |
| 15:35.14 | kerio | other than the fan connector being kinda thin |
| 15:35.17 | kerio | this one is insane tho ._. |
| 15:35.29 | DocScrutinizer05 | a fan at several 1000s of RPM can create amazing amount of voltage fed to the PCB |
| 15:35.37 | kerio | still haven't tried it, because "Step 1 - Remove the following pentalobe screws" |
| 15:35.53 | kerio | i want to believe there's some protection circuit, but probably not |
| 15:36.06 | DocScrutinizer05 | no obviously there isn't |
| 15:36.28 | DocScrutinizer05 | "how pressurized air can make your electronics go up in smoke" |
| 15:36.29 | kerio | there's glue EVERYWHERE |
| 15:36.37 | kerio | ;-; |
| 15:37.29 | ceene | does that happen? |
| 15:37.37 | kerio | sure |
| 15:37.57 | kerio | there's a reason it's very very recommended to detach the fans and prevent them from spinning when using compressed air |
| 15:37.59 | ceene | i'm used to clean pcs with air |
| 15:38.16 | ceene | does that break them? |
| 15:38.40 | DocScrutinizer05 | ceene: see https://en.wikipedia.org/wiki/Package_on_package |
| 15:38.58 | ceene | DocScrutinizer05: yeah, i was reading that |
| 15:39.03 | DocScrutinizer05 | ceene: yes, when the fann starts to spin very fast |
| 15:39.20 | ceene | i don't think any of the people i know at my uni would be able to unsolder that |
| 15:39.43 | ceene | oh, i've made several of them do that... just for fun :/ |
| 15:39.53 | ceene | didn't know it was harmful :/ |
| 15:44.06 | DocScrutinizer05 | I killed two laptops this way, without disassembling them |
| 15:44.34 | DocScrutinizer05 | the first was learning, the second was idiocy |
| 15:44.59 | DocScrutinizer05 | I thought I could control the effect by only blowing gently |
| 15:45.11 | DocScrutinizer05 | with a 10 bar canned air |
| 15:45.15 | DocScrutinizer05 | ;-P |
| 15:45.43 | ceene | i use a pressurizer :) |
| 15:46.06 | ceene | but i've only cleaned desktop computers, never a laptop |
| 15:48.27 | DocScrutinizer05 | anyway my recommmendation is: make DAMN SURE you block the fan from spinning for good, before you approach it with pressurized air or vacuum cleaner |
| 15:49.05 | ceene | will do from now on |
| 15:49.05 | DocScrutinizer05 | for added peace of mind, disconnect the fan from PCB if any possible |
| 15:49.30 | DocScrutinizer05 | so if your block fails, only the fan will go south |
