IRC log of #maemo for Thursday, 2020-01-16

Paliwhat arguments have you used?00:12
halftux0xFFFF -E dump0.fiasco &> dump0.log00:13
Paliseems that you have desynced stdout and stderr00:14
Paliat first lines is stderr and then stdout00:14
Palibut nevermind...00:14
*** badcloud_ has quit IRC00:14
Pali"File initfs_tmp is empty, removing it..." --> this is OK, stock Maemo on N900 does not use initfs00:15
Paliso it is empty00:15
halftuxgreat I know sdcard was to small with this attempt00:15
Pali"Error: Not enough free space (have: 27616083968, need: 28995223552)" --> this is due to small SD card00:16
Paliyou cannot put dump of SD card to SD card00:16
Pali"Error: Cannot open image file mmc_tmp: No such file or directory" --> this is just a reason for previous error00:16
Pali"Error: Cannot open image file initfs_tmp: No such file or directory" --> ignore this, 0xFFFF should probably do not show such message00:17
halftuxI see I thought it is emmc00:17
Paliyea, you are right, this is eMMC MyDocs, not SD card00:17
halftuxI needed to umount /home/usr/MyDocs00:18
halftuxand this whole image can be flashed back?00:18
halftuxwith emmc?00:18
Paliit is complicated00:18
Pali\/opt is stored on second partition of eMMC and this stuff is not backed up00:19
halftuxwhy that it is a none working fiasco file?00:19
Paliand this stuff cannot be even put into FIASCO image00:19
Paliso there is no way for do whole backup+restore00:19
halftuxah I see, is there a way to back it up seperatly und push it back?00:20
Paliyou can do backup of /opt manually00:20
DocScrutinizer05halftux: -v for those who love ugly00:20
Palie.g. via unix dd00:20
Palirestore is problematic00:21
Paliwithout /opt Maemo system does not bootup00:21
halftuxrescue os?00:21
Palibut there is a way, look at my "bootmenu"00:21
DocScrutinizer05/usr/share/applications/hildon # update-desktop-database00:21
DocScrutinizer05/usr/share/applications/hildon #00:21
Paliit can export whole eMMC via USB prior to booting Maemo00:22
Paliso if rootfs has installed bootmenu, and rootfs is in fiasco dump00:22
Paliyou would be able to restore rootfs, jump into bootmenu, export eMMC via USB00:22
Paliand then restore /opt00:22
PaliI do not know what is supported by backupmenu, but maybe something similar is possible00:23
halftuxok I will have a look thank you for your explanation00:23
Paliflashing MyDocs is problematic, IIRC it erases /opt00:23
DocScrutinizer05well, technically I think you could put /home on FIASCO00:23
DocScrutinizer05aka EMMC00:24
Palino, you cannot00:24
PalieMMC fiasco can contain only MyDocs part00:24
Palipart /home is IIRC maped to /opt00:24
Paliit is on same partition00:24
Palithere is symlink or bind mount or other technique00:25
Palibut I do not remember all details, at least I was not able to put /opt or /home into fiasco image00:25
Palibut that is not a final proof that it is impossible00:26
halftuxbut it is interesting, is stock /opt empty?00:26
Paliyes, stock /opt is empty, but stock rootfs has some init scripts which moves some parts from /usr to /opt00:27
DocScrutinizer05basically yes, though root image runs optify00:28
Paliinit scripts which do that only on first boot of stock rootfs00:28
infobotoptification is a inventive duct tape workaround to reclaim space in fs root, done due to the fact the systeminit *and* partitioning is FUBAR,,_Deploying_and_Distributing/Installing_under_opt_and_MyDocs, or ""OMG - I wish they looked into FHS and moved /usr to eMMC"", bullet1,2 and fhs-2.3.html#PURPOSE16 dot3"00:28
Paliand all maemo applications from extras install DEB packages to /opt00:28
DocScrutinizer05hmm, I think they also run optify00:29
DocScrutinizer05or at least that's one of the options00:29
Palianother problem of 0xFFFF is that it does not have implementation of flashing eMMC images (I had not time to finish it)00:47
halftuxPali: when I using your fiasco for cloning N900 HW:2101 to N900 HW:2104 I need to extract the fiasco and correct the xloader.bin and nolo.bin?00:47
halftuxah I see now your message that is sad I thought the original eMMC00:49
Paliseems that 2101 and 2104 HW revs uses different bootloader00:49
PaliNokia's flasher-3.5 can flash eMMC images viac USB00:50
Palibut 0xFFFF does not implement it00:50
Palianyway, here is a quick fix to hide those error messages about missing files:
DocScrutinizer05you generally shall not flash NOLO00:51
Palithat is truth, unless you have old version00:51
Pali0xFFFF has some filter argument to specify which image types from FIASCO images would be flashed00:52
Paliso unpack & pack could be avoided00:52
halftuxah ok thats something00:52
DocScrutinizer05how could you? was NOLO ever updated? and if yes, what for?00:52
Paliyes, PR1.3 has new version of NOLO as in PR1.000:53
Paliand IIRC Nokia distributed all devices with PR1.0 version00:53
Palibut if you are going to unpack FIASCO, do not forget about metadata00:53
Paliso when building a new fiasco, do not forget for specififying image version and HW revision00:54
Paliand type00:54
DocScrutinizer05I actually wonder how Nokia made COMBINED that did not have optification already done on them00:55
halftuxwhat is image version?00:55
halftuxor better what does it mean in your example you have 1.000:56
Palie.g. version of NOLO, version of kernel or version of rootfs00:56
Paliuse "-i" argument to show it00:56
halftuxok thank you lots of input this evening :)00:57
Palithere is an unfinished attempt for writing support for flashing eMMC images:
Paliif somebody want to finish it I can help00:58
halftuxhmm I will look if I am able to understand01:00

badcloud_Or should I just use one that I can find on the debian repos14:22

badcloud_Anyone know where to find dpkg-dev?19:45
KotCzarnybut if you want to do any dev work you should either install scratchbox on pc or you can try my devel chroot for on-device dev work19:48
*** luke-jr has quit IRC19:49
badcloud_I suppose compiling on the device isn't a good idea?19:52
KotCzarnybeen there, done that19:52
KotCzarnybut definitely it needs to be done in some chroot19:53
KotCzarnyand remember that other restraint is available memory19:56
KotCzarnyor lack of19:56
