| 14:35.05 | g1powermac_XU | anyone know what this mean when booting an embedded ARM kernel: checking if image is initramfs...it isn't (bad gzip magic numbers); looks like an initrd ? |
| 14:49.20 | *** join/#edev prpplague (n=dave@mail.americanmicrosystems.com) |
| 14:55.29 | g1powermac_XU | heeeeey prpplague |
| 14:55.37 | prpplague | g1powermac_XU: greetings |
| 14:55.45 | prpplague | get your stuff booting? |
| 14:55.47 | g1powermac_XU | prpplague, oh man, so glad you're here :-) |
| 14:55.51 | prpplague | uh oh |
| 14:56.02 | g1powermac_XU | I've been trying all night and day to get this thing to boot. . . |
| 14:56.31 | g1powermac_XU | nothing that I have tried has seemed to work |
| 14:56.52 | g1powermac_XU | after uploading the kernel and initrd, I ran a status command on blob |
| 14:57.07 | g1powermac_XU | and got this for the ramdisk: |
| 14:57.09 | g1powermac_XU | ramdisk (0x00240000): downloaded at 0xa0500000, 1577472 bytes |
| 14:57.26 | g1powermac_XU | so I tried both addresses mentioned there, neither work |
| 14:57.40 | g1powermac_XU | I tried various offsets, nothing |
| 14:57.44 | prpplague | g1powermac_XU: can you post your kernel boot log? |
| 14:57.55 | prpplague | g1powermac_XU: pastebin.ca |
| 14:57.58 | g1powermac_XU | sure |
| 14:58.43 | g1powermac_XU | only issue here is something gets convoluted when its sending the boot message |
| 14:58.44 | prpplague | g1powermac_XU: i don't have a large amount of time today, i've got an audio driver issue with wince |
| 14:58.48 | chouimat | happy Canada day to all |
| 14:59.12 | g1powermac_XU | prpplague, ahh, me neither as well |
| 14:59.17 | g1powermac_XU | need to finish another project |
| 14:59.31 | prpplague | darn if i knew it was canada day, i would have stayed home and watched stange brew while drinking molson |
| 14:59.42 | g1powermac_XU | http://pastebin.ca/1480798 |
| 15:00.18 | g1powermac_XU | one spot it got convoluted on is this line: |
| 15:00.20 | g1powermac_XU | NET: Registered protocol familyt (bad gzip magic numbers); looks like an initrd |
| 15:00.26 | chouimat | g1powermac: hehe |
| 15:00.31 | g1powermac_XU | it's really two lines that it merged together |
| 15:01.23 | prpplague | g1powermac_XU: doesn't look as though you have initrd support turned on in your kernel. please paste your .config file |
| 15:01.24 | g1powermac_XU | the second line really should be: checking if image is initramfs...it isn't (bad gzip magic numbers); looks like an initrd |
| 15:01.54 | g1powermac_XU | hrmm |
| 15:01.59 | g1powermac_XU | I selected initrd support |
| 15:02.11 | prpplague | pastebin your .config |
| 15:02.53 | g1powermac_XU | http://pastebin.ca/1480802 |
| 15:03.23 | g1powermac_XU | btw, is the ramdisk_size boot param needed? |
| 15:05.52 | prpplague | g1powermac_XU: that normally is passed with your kernel args |
| 15:06.16 | prpplague | g1powermac_XU: ok, everything looks good |
| 15:06.30 | prpplague | g1powermac_XU: ok how big is your compressed ramdisk? |
| 15:06.36 | g1powermac_XU | 1.5mb |
| 15:06.45 | g1powermac_XU | it decompresses to just under 6mb |
| 15:08.07 | g1powermac | erm, actually the actual file is bigger than 6mb, but in any regards, I had the ramdisk_size option as big at 10mb at one point |
| 15:10.00 | g1powermac | has been playing with every value I can think of |
| 15:14.23 | prpplague | g1powermac: ok so most likely it is a memory location issue |
| 15:14.39 | g1powermac | ahh jeeze |
| 15:14.46 | g1powermac | *sigh* |
| 15:15.03 | g1powermac | ok, so how do I figure out where the thing was really loaded to? |
| 15:24.45 | prpplague | g1powermac_XU: didn't GPSFan have some images that worked? |
| 15:25.04 | g1powermac | he used initramfs |
| 15:26.16 | prpplague | g1powermac: but not with a combined kernel image |
| 15:26.23 | prpplague | g1powermac: should have been two seperate files |
| 15:26.33 | g1powermac | hmm, he did it all combined |
| 15:26.37 | g1powermac | to my knowledge |
| 15:26.50 | g1powermac | at least thats what he showed me a year ago when I was doing this |
| 15:27.39 | g1powermac | but at that time I wasn't trying to use the default rootfs coming from buildroot, which is a bit bigger and puts the kernel over the 2.2mb limit |
| 15:28.04 | prpplague | g1powermac: hmm something doesn't sound right |
| 15:28.42 | g1powermac | could be wrong though, he may have done something different between then and now |
| 15:29.05 | prpplague | g1powermac: do you have a url for GPSFan z2 info? |
| 15:29.22 | g1powermac | all I know for sure was that I did boot a kernel with an extremely simple initramfs a year or so ago |
| 15:29.50 | g1powermac | to my knowledge, he doesn't have a site with this stuff |
| 15:30.33 | prpplague | g1powermac: oh i thought you said you were looking at his notes |
| 15:30.43 | g1powermac | ahh |
| 15:31.09 | g1powermac | nope, don't have his notes |
| 15:32.10 | chouimat | hi g1powermac prpplague |
| 15:32.20 | g1powermac | heya chouimat |

| 15:33.04 | chouimat | hehe |
| 15:33.20 | g1powermac | prpplague, would there be a way to tell where this initrd is going by booting a kernel with a really simple initramfs? |
| 15:34.08 | prpplague | g1powermac: no, i just dont know enought about the memory allocation on the z2 to point you in the right direction |
| 15:34.39 | g1powermac | hmm |

| 16:12.08 | g1powermac | oh |
| 16:12.20 | g1powermac | xdownload ramdisk rootfs.arm.ext2.gz |
| 16:12.24 | devilsadvocate | have any of you folks used the Atmel SAM-ICE with anything? |
| 16:12.44 | prpplague | g1powermac: ok, you need to look at what memory address blob associates with ramdisk |
| 16:12.51 | prpplague | devilsadvocate: not i |
| 16:13.19 | g1powermac_XU | well, after uploading, when i run status on blob, I get this: |

| 16:15.34 | g1powermac_XU | thats what I thought once I found this out |
| 16:15.38 | g1powermac_XU | sure |
| 16:16.28 | g1powermac_XU | I have mounted the image on this system without issues |
| 16:18.17 | g1powermac_XU | http://filebin.ca/ekusz/rootfs.arm.ext2.gz |
| 16:18.21 | prpplague | g1powermac_XU: i just want to double check |
| 16:20.24 | prpplague | g1powermac_XU: when you mounted it locally, how did you repackage it? |
| 16:21.03 | g1powermac | I didn't, I just copied it so I didn't play with the original, gunzipped, and mounted it |
| 16:21.48 | prpplague | ahh ok |
| 16:22.46 | prpplague | g1powermac: try it again with this command line: console=ttyS2,115200 root=/dev/ram0 initrd=0xa0500000,8M init=/bin/sh |
| 16:23.12 | g1powermac | k |
| 16:23.18 | g1powermac | give me about ten minutes to load it |
| 16:24.38 | g1powermac | no ramdisk_size, ehh? |
| 16:32.56 | prpplague | no |
| 16:34.27 | g1powermac | just to be clear, what I tell blob to pass as boot params will override what I wrote in the kernel config, right? |
| 16:35.17 | prpplague | g1powermac: it is suppose to, unless there is something hacked in your kernel |
| 16:36.29 | g1powermac | k |
| 16:41.44 | g1powermac_XU | nope, still died |
| 16:42.34 | g1powermac_XU | still getting that checking if image is initramfs message |
| 16:43.02 | g1powermac_XU | that whole bit is weird |
| 16:43.16 | g1powermac_XU | because it checks it, then right after frees the memory |
| 16:43.33 | g1powermac_XU | without ever trying to load it |

| 17:21.05 | prpplague | looks |
| 17:24.49 | prpplague | g1powermac: i wonder if blob isn't passing the correct atag for initrd |
| 17:25.00 | prpplague | g1powermac: ahh i bet so |
| 17:26.33 | g1powermac | kindly asks what an atag is :-) |
| 17:27.23 | prpplague | kernel arguement tags |
| 17:27.31 | g1powermac | ahh |
| 17:27.35 | prpplague | basically a linked list of values and such |
| 17:27.36 | g1powermac | hmm |
| 17:27.48 | prpplague | g1powermac: you have th blob source right? |
| 17:27.59 | g1powermac | can get it, don't have it right here with me |
| 17:28.36 | prpplague | g1powermac: you should be able to grep for ATAG_INITRD and ATAG_RAMDISK |
| 17:30.05 | g1powermac | hmm, there's two sets of blob patches on the zipit site |
| 17:30.13 | prpplague | g1powermac: the bootloader is suppose to properly pass those arguments, however if zipit folks never tested it with an initrd, them may never have noticed it |
| 17:31.31 | g1powermac | oh dear |
| 17:31.44 | g1powermac | you should read this comment in one of these patches for the atag initrd |

| 17:35.40 | prpplague | looks |
| 17:36.01 | g1powermac | is uploading the entire patch so you could take a look |
| 17:36.34 | prpplague | g1powermac: indeed it has |

| 17:36.56 | prpplague | g1powermac: ATAG_INITRD now takes a physical address |
| 17:38.07 | g1powermac | hmm |
| 17:38.23 | g1powermac | so, what I've been doing should have worked. . . |
| 17:38.36 | prpplague | g1powermac: yea |
| 17:38.45 | prpplague | g1powermac: i suspect something is still broken in the bootloader |
| 17:38.59 | prpplague | g1powermac: i'm really surprised that zipit folks used blob |
| 17:39.50 | g1powermac | http://filebin.ca/qchjog/blob-2.0.5-pre2_to_zipit2-1.0.patch |
| 17:39.55 | g1powermac | there's the one patch |
| 17:40.08 | prpplague | g1powermac: when doing these types of things, it is always good to have a reference platform |
| 17:41.42 | g1powermac | the second patch has nothing mentioned in it about atags |
| 17:42.54 | g1powermac | though its got a disassembly of .text, interesting |
| 17:44.28 | g1powermac | with some references to initrd and ramdisk tags |
| 17:44.56 | g1powermac | http://pastebin.ca/1480992 |
| 17:52.02 | g1powermac_XU | ohhhhhhhhhh, this is interesting |
| 17:52.22 | g1powermac_XU | I decided to try running ptprint command on blob |
| 17:52.31 | g1powermac_XU | this is what I get |
| 17:53.04 | g1powermac_XU | http://pastebin.ca/1481000 |
| 17:53.53 | g1powermac_XU | not sure if that part under the kernel where it says contains cramfs has any significance |
| 17:54.42 | prpplague | that looks correct |
| 17:55.16 | g1powermac | I'm going to try downloading the kernel and rootfs and see what it says then |
| 18:02.57 | g1powermac_XU | hmm, interesting, the ptprint output remained the same |
| 18:04.30 | g1powermac | is unsure what to try next |
| 18:07.45 | ds2 | *splat* |
| 18:08.19 | g1powermac | forces ds2 to comb through the blob source code ;-) |
| 18:08.45 | ds2 | sends a bill to g1powermac |

| 18:10.57 | prpplague | lordy lordy i wish i could find someone to talk to about wince dev |
| 18:12.39 | ds2 | =) |
| 18:12.48 | g1powermac | prpplague, ok, so you still suspect the initrd atag is being messed up, anyway from the kernel side to spit out to the screen what blob has fed it? |
| 18:13.24 | prpplague | g1powermac: seems like the direction its headed, but without doing more digging. ...... |
| 18:14.55 | ds2 | hack up the code in setup.c and see if that helps |
| 18:15.06 | ds2 | if so, that ought to confirm you have an ATAG issue |
| 18:17.29 | devilsadvocate | grumbles |
| 18:17.41 | g1powermac | hmm |
| 18:17.44 | devilsadvocate | shouldve just bought the damn segger j-link instead of atmel sam-ice |
| 18:17.48 | ds2 | prpplague: rumor has it that there are more CE work then there are Linux work at the moment? |
| 18:17.59 | devilsadvocate | the damn thing refuses to recognize atmels own chip |
| 18:18.13 | ds2 | deviladvocate: nah... should have bought a Lauterbach ;) |
| 18:18.14 | florian | devilsadvocate: the j-link sucks for other reasons |
| 18:18.21 | florian | ds2: :) |
| 18:18.29 | devilsadvocate | Lauterbach? |
| 18:18.33 | devilsadvocate | googles |
| 18:19.01 | ds2 | waits for the sound to propagate ;) |
| 18:19.24 | g1powermac_XU | ok this was odd |
| 18:19.42 | devilsadvocate | florian: other reasons like? |
| 18:20.34 | florian | devilsadvocate: the support from open source tools is not the best |
| 18:20.34 | g1powermac_XU | prpplague, I ran the kernel without even loading the initrd to blob |
| 18:20.57 | g1powermac_XU | prpplague, and I didn't get that kernel message about checking the initramfs |
| 18:21.15 | devilsadvocate | i just want something that will _work_. I'm in the process of ordering IAR, but thats because for the life of me i couldnt get gnu-arm to work and i dont have the time to mess with it anymore |
| 18:21.25 | g1powermac_XU | still died, but interesting, mainly because I didn't touch the boot params, it was suppose to load the initrd at the address |
| 18:21.55 | prpplague | still sounds like something is being overriden |
| 18:22.04 | devilsadvocate | since im the only person on my team who has real prior mcu experience (no arm, only avr), and i need to over see work on avr, arm7, dsPIC, and and msp430 |
| 18:22.17 | ds2 | devilsadvocate: The Lauterbach will just work. |
| 18:22.31 | ds2 | I think the BDI3000 is also in that same general group of working |
| 18:22.33 | devilsadvocate | the ICD ? |
| 18:22.51 | ds2 | both of these are JTAG debuggers |
| 18:23.01 | g1powermac | prpplague, hmm, but wouldn't you think that initramfs message would show up, regardless? |
| 18:23.21 | devilsadvocate | seriously considers ordering one |
| 18:23.42 | ds2 | deviladvocate: the catch if you haven't found it is they are $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ |
| 18:23.46 | prpplague | g1powermac: not nessarily |
| 18:23.57 | prpplague | g1powermac: i'd just have to load up the kernel with a bunch of printk's |
| 18:24.05 | g1powermac | hmm |
| 18:24.38 | devilsadvocate | havent found it yet |
| 18:24.41 | ds2 | g1powermac: besure CONFIG_DEBUG_LL is enabled in case something else is getting lost |
| 18:24.44 | devilsadvocate | their website crashed my firefox :\ |
| 18:24.50 | ds2 | oh |
| 18:25.00 | devilsadvocate | ds2: i really really wanted to buy the one from arm corporation itslef |
| 18:25.05 | g1powermac | hmm, I'll check |
| 18:25.06 | devilsadvocate | but the damn thing was 2000$ |
| 18:25.25 | ds2 | devilsadvocate: IIRC, the Lauterbach might be more |
| 18:25.36 | devilsadvocate | wtf |
| 18:25.38 | devilsadvocate | ok |
| 18:25.42 | devilsadvocate | no lauterbach |
| 18:25.47 | ds2 | people that have it tend to be happy with it and it works |
| 18:26.07 | ds2 | I think the Lauterbach's by default have the ETM stuff also |
| 18:26.30 | florian | its not a product for home use :) |
| 18:26.48 | ds2 | so it comes down to -- if you need it to work and don't have time.... |
| 18:26.49 | devilsadvocate | isnt there like a decent standard thing that plays well (with open source software would be nice) atleast with the hardware that can put stuff onto an arm7 based mcu, and do a little bit of debugging and such? |
| 18:27.00 | florian | in fact you can even spend EUR 2000 on a flashing tool by segger. |
| 18:27.18 | devilsadvocate | was so much happier in the avr world. |
| 18:27.20 | florian | just flashing... things tat are solved with a few lines of openocd configuration! |
| 18:27.25 | ds2 | I'd think the flyswatter could do it if you arewilling to putz with the openocd stuff |
| 18:28.09 | devilsadvocate | avr-gcc and avrdude and usbasp used to be all you need, and maybe a dragon and avrstudio for debugging |
| 18:28.13 | devilsadvocate | life was simple |
| 18:28.16 | devilsadvocate | life was fun |
| 18:28.20 | ds2 | the problem with the Seggers is they make vendor locked versions |
| 18:28.20 | devilsadvocate | </rant> |
| 18:29.09 | devilsadvocate | yeah, the one i have is Atmel vedor locked, which wouldnt be a problem except that it doesnt work with Atmel chips and i have no clu who to contact for support - atmel?, segger?, iar? |
| 18:29.40 | ds2 | whoever sold it |
| 18:29.54 | ds2 | <--- have a strong dislike for vendor locked crap |
| 18:30.15 | devilsadvocate | atmel sold it |
| 18:30.18 | devilsadvocate | i do to |
| 18:30.30 | ds2 | i got the ADI locked version from them for free and I still haven't bother setting it up |
| 18:30.32 | devilsadvocate | hm, i wont if atmel has like a support email address or something i can bug |
| 18:30.35 | devilsadvocate | looks |
| 18:31.35 | devilsadvocate | i hate them too, but well, i know im going to use an atmel chip, and when i ordered it i didnt _know_ there were unlocked versions |
| 18:31.50 | devilsadvocate | there are like a hundred jtag emulators in the list on atmels page, so i figured the safest bet would be to buy the one that _they_ sell |
| 18:32.04 | ds2 | hahahah |
| 18:32.28 | ds2 | did they call it a Jlink on their site? |
| 18:32.39 | devilsadvocate | no, its called an Atmel SAM-ICE |
| 18:32.59 | ds2 | ah. so you are another victim of Branding |
| 18:33.02 | devilsadvocate | i knew it was locked to atmel chips, but quite frankly i didnt care much as long as it _worked with atmel chips_ |
| 18:33.07 | devilsadvocate | yes, that i am |
| 18:33.34 | ds2 | the legal swindle scheme to siphon money out of people; sell crap under one name. When they get pissed, rebrand and repeat. |
| 18:33.49 | devilsadvocate | it was only later that i realized that jtag on arm is heavily standardized and hardware doesnt _have_ to be locked to one vendor |
| 18:34.37 | devilsadvocate | like, the thought of a debugger working on avr and pic is outlandish |
| 18:36.50 | devilsadvocate | how is the open source world support, like, really, for arm7. does it work? should i check if my particular mcu is well supported/pick the chip based on support (right now im using the AT91SAM7X512 |
| 18:37.36 | devilsadvocate | im talking about the whole stack here - the yagato / gnuarm toolchains - on windows or linux (at this point im not picky anymore :P) |
| 18:38.45 | devilsadvocate | the thought of being locked in by IAR is a little scary at this point. |

| 21:29.38 | ds2 | g1powermac: are you using initrd (seperate ramdisk) or a combine initramfs thing? |
| 21:30.09 | g1powermac | well, this here super solder flux did wonders, was able to piece together my glasses with a giant blob of solder :-) |
| 21:30.29 | g1powermac | ds2, separate |
| 21:30.56 | ds2 | g1powermac: in that case, I wonder if it wants a virtual address instead of a physical address or vice versa |
| 21:31.58 | g1powermac | well, lets assume a virtual address since I have not tried that that, how would I find the address? |
| 21:31.58 | g1powermac | s/that/yet |
| 21:32.31 | ds2 | for the omaps, I'd look at the board file to see how they map ram around... not sure on other platforms |
| 21:34.49 | g1powermac | hmm |
| 21:35.40 | g1powermac | ds2, is this what you're referring to: http://pastebin.ca/1480850 ? |
| 21:38.56 | ds2 | no |
| 21:39.05 | ds2 | that looks like the physical address map |
| 21:39.33 | ds2 | why not try an initramfs with it included? |
| 21:39.50 | g1powermac | an initramfs and an initrd? |
| 21:46.36 | g1powermac | is building a zImage that is as small as possible with an initramfs |
| 21:46.50 | g1powermac | hopefully get it under 2.2mb |
| 21:49.39 | ds2 | no, just initramfs |
| 21:49.47 | ds2 | no initrd |
| 21:50.05 | ds2 | if that still happens, then you need to massage the initramfs cpio file differently |
| 21:50.22 | ds2 | it is sensitive to the options used with CPIO |
| 21:50.24 | g1powermac | hmm |
| 21:50.39 | g1powermac | we'll see in the next 20 mins |
| 21:51.16 | g1powermac | hopefully, should be able to get this thing below 2.2mb |
| 21:51.27 | ds2 | you don't have a quad quad core machine with 64G doing your builds? :D |
| 21:51.35 | g1powermac | hehe, I wish |
| 21:51.43 | g1powermac | plus that isn't the main bottleneck |
| 21:51.53 | g1powermac | the issue is with the stupid serial download |
| 21:52.18 | ds2 | oh |
| 21:55.28 | g1powermac | woo, 2.1mb |
| 22:04.33 | Mirell | PKG_CONFIG=/bin/true is my hack of the day |
| 22:04.45 | agaffney | heh |
| 22:05.11 | g1powermac | heh |
| 22:05.30 | agaffney | my hack of the day is doign a remote reinstallation of a RHEL2 box by putting the CentOS-5.3 PXE kernel/initrd in /boot, pointing grub at them, and setting it to reverse VNC back to me |
| 22:05.57 | g1powermac | my hack is still in progress. . . |
| 22:06.05 | agaffney | I'm interacting with anaconda via VNC right now |
| 22:06.21 | agaffney | of course, that was after fighting with grub for 1.5 hours trying to figure out why it wouldn't boot my new kernel |
| 22:06.30 | agaffney | turns out there was a GRUB floppy in the drive :p |
| 22:06.31 | g1powermac | agaffney, fun |
| 22:06.33 | g1powermac | hah |
| 22:06.37 | agaffney | yeah... |
| 22:06.54 | agaffney | I had someone there remove the floppy, and it hangs at "GRUB Loading stage 1.5" when booting from the HD |
| 22:06.59 | g1powermac | holy mother of perl |
| 22:07.00 | agaffney | so the floppy went back in, and I edited that grub.conf |
| 22:07.04 | g1powermac | we have boot! |
| 22:07.48 | agaffney | whatcha bootin'? |
| 22:08.03 | g1powermac | zipit2 |
| 22:08.06 | agaffney | ah |
| 22:08.20 | g1powermac | wonders why he didn't get a prompt on the host machine side |
| 22:08.31 | g1powermac | got a prompt on the z2 side |
| 22:08.50 | agaffney | hmm, and now here's the problem... |
| 22:08.57 | agaffney | the centos install is done, but the floppy is still in the drive |
| 22:09.00 | agaffney | and nobody is there now |
| 22:09.22 | agaffney | and of course, who knows if it'll boot off the HD this time |
| 22:10.36 | agaffney | well, grub on the floppy will fail to boot both entries...maybe it'll be nice and skip to the next BIOS boot device |
| 22:10.45 | agaffney | I doubt it, but weirder things have happened :P |
