12:42 < TheSeven> benedikt93: please do not remove any function pointers from the efi guids page
12:43 < TheSeven> adding information is of course fine, but valuable references tracked down through rather time consuming reverse engineering should always be kept
12:47 < benedikt93> ok
12:48 < TheSeven> (even if the link you provided is probably way more useful than those function pointers, there might be situation where one needs to check how something is actually implemented, or how the hardware behind that protocol works)
12:49 < TheSeven> situations*
12:50 < TheSeven> oh, and thanks once again for spotting that relocation bug
12:50 < TheSeven> this was what made it impossible to figure out all this information when I tried it the last time
12:51 < benedikt93> this made me wonder for a long time why dxemain accessed stuff behind its data section
12:52 < benedikt93> (and therefore checking the PELoader for adding sthg to the loaded image)
12:52 < TheSeven> this might still happen, as I don't allocate the bss segments in IDA
12:53 < benedikt93> "SizeOfUninitializedData" ?
12:53 < TheSeven> but what baffled me was that at one place in the FTL, it did fetch the BOOTSERV pointer and store it into the usual variable, and then in the entrypoint function load some different variable and use it as if it were the BOOTSERV pointer
12:53 < TheSeven> yeah
12:53 < benedikt93> at least for dxemain this one is 0 (n3g)
12:53 < TheSeven> however it seems like most modules don't actually use a bss
12:54 < TheSeven> however i think i remember seeing non-zero values in that field for some modules
12:55 < benedikt93> <TheSeven> but what baffled me was that at one place in the FTL, it did fetch the BOOTSERV pointer and store it into the usual variable, and then in the entrypoint function load some different variable and use it as if it were the BOOTSERV pointer <-- weird, so maybe still some bad reloc

12:59 < benedikt93> TheSeven, btw, you're currently working on the n4g ?
13:01 < TheSeven> no, that was before I fixed the relocs :)
13:01 < benedikt93> ah, ok^^
13:01 < TheSeven> and yes, i'm working on the n4g ftl/nand area currently (and everything referenced by it of course, especially the pmu)
13:09 < benedikt93> also,do you know of any datasheet that about matches the s5l8702's SPI?
13:16 < TheSeven> IIRC the s5l8702 one seems to be the closest one
13:16 < TheSeven> and some differences have been reverse engineered
13:16 < TheSeven> but as we have a fully working driver for that one including DMA I don't really care

13:37 < benedikt93> also interesting is the amount of dead code and unimplemented functions
13:37 < benedikt93> which is pretty large

16:05 < KeN^> Hey, TheSeven, I got a couple of quick questions before I try out that tool you gave me
16:06 < TheSeven> which would be?
16:06 < KeN^> can I plug the iPod into a charger after I run UMSboot and leave it charging like that?
16:07 < KeN^> just want to make sure I don't fry anything...
16:09 < TheSeven> yes, you just need to make sure that it is powered
16:09 < TheSeven> you can also let it run on battery for up to an hour (in case you need to move it somewhere else)
16:10 < KeN^> (and just to make sure) rockbox-ipodclassic-r29777-20110424.zip from the wiki should be able to use this, yes?
16:12 < TheSeven> yes, all rockbox builds from the wiki will be able to use it
16:12 < TheSeven> well, unless the damage pattern is extremely complex, in which case i would have to make a custom one...
16:13 < TheSeven> the freemyipod.org rockbox builds will allow for up to 300KB or something of mapping tables, which is sufficient for my badly broken drive
16:13 < KeN^> Thanks for answering my questions
16:13 < KeN^> running the tool now, this is awesome :>
16:13 < TheSeven> and as i said: expect it to run for a couple of days
16:14 < KeN^> kk
16:14 < TheSeven> if will be reasonably fast in the intact areas, but might seem to completely stall for a couple of hours in the damaged zone
16:14 < KeN^> I'll just chuck it in a drawer with the charger and leave it there
16:15 < KeN^> When do I know when it's done?
16:16 < KeN^> How*
16:17 < TheSeven> you'll see the sector numbers progress slowly until the end of the disk
16:17 < TheSeven> then it will be busy for another couple of minutes while it's planning the remapping, and finally it should go into the "FINISHED" state
16:18 < KeN^> then just reset? (menu+select for a while)
16:18 < TheSeven> yeah
16:18 < KeN^> thank you so much, you're my hero man
16:19 < TheSeven> afterwards you should have a smaller but perfectly working drive, at least in theory
16:19 < TheSeven> i remember that tool having some bug that might lead to a screwed file system after it finished
16:19 < TheSeven> so if rockbox is acting up, just chooser "reformat data partition" from the tools menu and try again
16:20 < KeN^> kk
16:20 < KeN^> what kind of an education/experience do you have? this stuff seems really advanced to me
16:25 < KeN^> right, that's offtopic, sry
16:26 < bcoco85> regarding fs recovery; i was wondering if this can be done from usb in disk mode
16:26 < bcoco85> like when partitioning
16:28 < Farthen> the ipod classic does not support disk mode at the moment (and we don't know if ever)
16:28 < Farthen> so you have to do that through rockbox

17:59 < TheSeven> if any of the guys with non-working USB turns up, please make them try this build: http://files.freemyipod.org/tmp/installer-ipodclassic-usbfixcandidate.ubi
17:59 < TheSeven> if that works, i'm gonna commit that change and release a new official version

18:55 < bcoco85> non-wirking usb?
18:55 < bcoco85> o
19:00 < bcoco85> you mean, bricked?
19:02 < benedikt93> nope, there were some whose USB made their players lock-up on (dis-)connection
19:05 < bcoco85> rockbox or emcore?
19:12 < TheSeven> there were some devices where USB basically stopped working after the first reboot
19:12 < TheSeven> both emcore and rockbox are affected, as they both use the same driver

19:43 < bcoco85> thanks
19:43 < bcoco85> is to be sure
19:43 < bcoco85> i remember, in previous versions, rockbox and umsboot freezed if loading with usb plugged in
19:44 < bcoco85> but only had to restart without usb plugged in
19:44 < bcoco85> and wait a few seconds (so all is well loaded)
