11:28.47FatPhilanyone familiar with the n950 bootloader. Where does the mtd partition info in the kernel cmdline come from? I have no mention of a moslo partition, yet apparently others do have in theirs
11:30.09Aardit's stored in the cal area. n950s (the ones handed out as developer devices) should have a moslo partition, older prototypes and n9s don't have one

11:37.30FatPhilyeah, this is a dodgy device with a broken screen from a friend of a friend who knew I wanted to do some poking around
11:38.54FatPhilAnd dicking about with CAL is a rather risky operation. Has someone worked out what's where, and perhaps even created safe tools to mess with it?

15:08.48FatPhilAard: interesting. You've pointed me towards this: https://dev.openwrt.org/browser/packages/utils/calvaria/files/src/calvaria.c
15:11.09FatPhilI'm wondering what mechanism "your CAL areas a permanently locked while in open mode" takes?
15:13.07AardJonni might know something there

17:26.57FatPhilNo R&D cerificate on this device, but writing to the CAL area works:
17:26.57FatPhil# dd if=dev_mtd1_c of=/dev/mtd1 bs=32768
17:26.58FatPhil12+0 records in
17:26.58FatPhil12+0 records out
17:26.58FatPhil393216 bytes (384.0KB) copied, 0.036468 seconds, 10.3MB/s
17:28.06FatPhilSo there's nothing physically preventing it. Gonna try a downgrade of software, and make sure that fails...
17:29.58abdid you check that the content is the same as in dev_mtd1_c ?
17:33.36*** join/#harmattan Luke-Jr (~luke-jr@unaffiliated/luke-jr)
17:36.04FatPhilab: indeed - the contents are not the same, so the write is not performed, and without the kernel reporting an error

19:27.51JonniFatPhil: yes on secure mode writing to cal area works, but be carefull as editing wrong places will permabrick the device. In openmode bootloader order cal area of the flash to be ro.
19:30.49FatPhilJonni: what's "secure mode" in this context?
19:31.24FatPhilNot so worried about permabricking this one, as it's a junker from a skip with a broken screen
19:31.45JonniI mean normal mode == secure mode vs custom kernel == openmode
19:32.32FatPhilhmm, my tests using dd, just copying back an old known copy of the whole of the partition, indicated that the write had silently not taken place
19:33.18FatPhilI've now got Nemo/Mer on it, I guess I could try my tests from within that context
19:34.25Jonniwell if you have nemo/mer on it, then your in openmode, and that partition is readonly
19:34.34Jonniso dd will not write there
19:34.53FatPhilDo you know how the writes are blocked?
19:35.15Jonniyes bootloader order flash hw to mark that area ro
19:36.03FatPhilSo if it can be worked out how the bootloader does that (RE, or put it in emulation?) then perhaps it can be undone?
19:36.05Jonniand only bootloader pa has access to call that API, kernel nor userspace have no way to change it back to rw
19:36.24FatPhilahhh, those dreaded PAs
19:36.56*** join/#harmattan Pat_o (~pat@37.160.72.168)
19:37.26Jonniso without access to master signing key your out of luck :
19:37.36FatPhilMy original plan was to try to get HArmattan/Alt_OS dual boot
19:37.49FatPhilalas that requires a moslo partition on onenand
19:38.37FatPhilwhich isn't the config on this device, so I was trying to trace where the partition came from
19:38.40Jonniwith ubiboot you dont need to change onenand at all
19:38.57JonniI have triple boot to nitdroid / harmattan and sailfish on my device
19:39.30FatPhilYeah, I was told you were doing Sailfish on all kinds of devices
19:40.09Jonniyou can just flash ubiboot kernel, and use sfdisk on cli to create as many partitions as you like on your device.
19:40.43FatPhilI'm prepared to experiment with ubiboot, this device is for experimentation more than actual use

20:55.00DocScrutinizer05well, at least that dialog between FatPhil and Jonni is what I could quote when somebody asks me why N9(50) are completely out of my range of interest
20:55.57AardDocScrutinizer05: even as somebody who has r&d certificates on his devices -- working on jolla devices is refreshingly painless for a change
20:56.20DocScrutinizer05I generally don't touch devices where some vendor-installed sw can do things I don't have any control over
20:56.30JonniI bet that N950 prices will drop below 300e when Sailfish devices start to hit the market.
20:56.59JonniI still have one extra N950 in unopened box as new.
20:57.03DocScrutinizer05Aard: good to hear
20:58.06DocScrutinizer05dang, I'm fighting my alter ego since ~one year at least to finally decide to sell N950, as long as it still cost more than gold
20:59.16AardDocScrutinizer05: even though parts are annoying -- there's some sentimental attachement to those devices for me
20:59.23DocScrutinizer05I think I haven't touched it since... 12 months
21:00.03DocScrutinizer05but I feel like it's a sort of ... special, and not for sale
21:00.52Jonnimy wife and wife's sister are using N950's as daily phone currently
21:01.00DocScrutinizer05dang
21:01.11Aardis using a jolla as daily phone currently ;)
21:03.07JonniAlready had to change broken displays there for 3 times :), they usually just drop the devices from 20cm hight
21:03.27Jonnin950's displays were quite fragile
21:04.06DocScrutinizer05wut? change N950 display? where from you get the spares?
21:04.22JonniI used to have a pile ;)
21:04.30DocScrutinizer05hah
21:04.53JonniI still have one or two left :)
21:05.07DocScrutinizer05and you don't happen to know any part number we could google for?
21:05.36Jonnithey were so customs that there is no part numbers anywhere. Thats a dead hardware.
21:05.46DocScrutinizer05indeed
21:06.27DocScrutinizer05LCD manufs are awesome regarding custom made built to specs low volumes
21:06.47DocScrutinizer05you wouldn't think you actually can get such low batch volumes
21:07.24DocScrutinizer05some start for a few 100s
21:07.29DocScrutinizer05units
21:07.45azeemmy N9 half-died the other day (no longer works with wall chargers, only charging via notebook/usb-hub), so now I have to see whether it'll last till Jollas are around for a good price or I might have to get an Android
21:08.08azeemcurrently sending back the second Nexus 4 as the N9 seems to keep living for a bit longer
21:08.23Aardhey azeem :)
21:08.24DocScrutinizer05ooooh apropos N9, any of you insiders knows where from Nokia got that 1GB RAM POP chip?
21:08.30azeemAard: heya!
21:08.58Aardpretty small world :)
21:09.03DocScrutinizer05actually "apropos N9 and custom made"

21:09.53DocScrutinizer051GB RAM POP doesn't even "exist", according to aunt google, Samsung, Hynix et al
21:10.24azeemwhat's a POP chip?
21:10.32azeemdoesn't the N9 have 1GB RAM anywa?
21:10.33DocScrutinizer05Package On Package
21:10.35azeemanyway*
21:10.42DocScrutinizer05piggyback chip on top of CPU
21:11.18DocScrutinizer05and yes, that's exactly the point: N9 has
21:11.37DocScrutinizer05has a non-existent chip
21:12.07Aardazeem: what's "a good price" for you?
21:12.36DocScrutinizer05I already pondered to buy used or broken N9s just to recover the POP chips
21:13.33Jonnisamsung was happy to provide those :)
21:13.43azeemAard: so far I bought my N900 and N9 on ebay, though I admit the 400 EUR which have been speculated aren't bad
21:13.43DocScrutinizer05hah
21:14.08Aardazeem: 'speculated'? we gave that number on our webpage :)
21:14.11azeembut the Nexus 4 I am returning was 250 EUR due to the sale
21:14.57azeemAard: on the part where it says "scroll down"?
21:14.59DocScrutinizer05I guess I have to actually disassemble my N9 finally. Instead of relying on the PCB photos in the schematics
21:15.15AardI personally can't stand the android ui at all. I'd rather go back to a classic palm treo than go for an android phone
21:15.26Aardazeem: sorry for that, we engineers didn't do the webpage :p
21:15.38azeemAard: ok, now I found out you have to use cursor keys
21:15.52azeemanyway, I didn't see it on the webpage so wasn't sure it was official
21:16.01azeemI actually like my Nexus 7 tablet
21:16.04DocScrutinizer05Jonni: or do you maybe even know the part number?
21:16.09Aardin the presales campaign we said 399
21:16.30azeemwhat really bugs me is how I have to check Facebook, Twitter, G+ etc. seperately
21:17.52Aardnavigation in the os and in apps in android is annoying (and parts are now getting annoying on n9 as well, after using jolla as main phone)
21:18.02azeemheh
21:18.47DocScrutinizer05Jonni: would save me from the tedious disassembly of my N9 to chack the *actual* writing on that POP chip, since the one in schamtics doesn't look like Samsung
21:19.03DocScrutinizer05check, even
21:19.17DocScrutinizer05and schematics
21:19.36JonniI  think that I have one disassembled N9 in work, so I can check on monday
21:19.50DocScrutinizer05with an actual part number I *might* be able to find soare parts in HK
21:20.01DocScrutinizer05:-) great!
21:20.58Jonnithere are also some devices with non-Samsung memory, but only few of those were sold to consumers
21:21.29Jonniso there were 2 different memory supliers
21:21.33DocScrutinizer05:nod: but one of them been used for the photo in Nokia's schematics
21:22.05DocScrutinizer05and that one has a manuf logo I never seen and wasn't even able to find out who it is
21:23.01DocScrutinizer05http://wstaw.org/m/2013/09/21/plasma-desktopiS3743.png
21:23.42DocScrutinizer05(e1) whatever
21:24.34DocScrutinizer05the part number is completely unknown
21:24.45JonniDocScrutinizer05: It was Numonyx
21:24.51DocScrutinizer05mhm
21:24.54DocScrutinizer05thanks
21:27.18JonniMicron bought Numonyx, so nowadays its Micron.
21:30.13DocScrutinizer05HAH, and micron doesn't offer *any* 1GB RAM POP
21:30.47DocScrutinizer05custom build?
21:31.14DocScrutinizer05like e.g LP5523 been
21:33.19DocScrutinizer05dinner time  o/
22:52.40HurrianDocScrutinizer05: isn't samsung the /other/ supplier of OneNANDs?

23:32.45DocScrutinizer05none of them lists >512MB LPDDR RAM (+NAND) cbp 168p POP
23:33.00*** join/#harmattan Melike (~Melike@5.46.135.58)
23:34.27DocScrutinizer05possibly since you need 3 chips for 2*RAM + 1*NAND when you want to go >512MB, the addr space of OMAP3 is limited to 512MB RAM but with 2 independant ChipSelect
23:35.27DocScrutinizer05so I guess when you want 1GB RAM you need to use 2 banks aka dies
23:35.46DocScrutinizer05o.O
23:39.15juicemeDocScrutinizer05, if it's custom made you just won't find it anywhere.
23:39.42juicememight be custom made with 2 dies, or a special die never released anywhere :)
