| 00:20.25 | ManoftheSea | destinal: ARM performance has always been respectable, when measured per-watt |
| 00:38.02 | destinal | ManoftheSea: no, not megahertz myth, in terms of instructions per second. increasing clock speed for a given SoC does typically create a linear increase in performance along with the clock speed |
| 00:38.30 | destinal | so I'm not saying "wow 3ghz", I'm saying, wow, something 50% faster than a stock A9 :) |
| 00:39.26 | destinal | and yeah, I mean of course it's going to take more power |

| 12:05.57 | mnemoc | to be able to debug that stuff properly and move forward I need to play with stuff in the .bin so I'm wasting my "spare" time in a compiler/decompiler... while waiting allwinner to release the 3.0.8 as promised by the now lost Tom/hipboi |

| 15:21.05 | zenitraM | quota? is there quota for open projects @github? |
| 15:21.08 | zenitraM | sure |
| 15:21.44 | mnemoc | there is a limit to avoid abuses, but not sure how much |
| 15:22.13 | mnemoc | otoh my linux repo is counted only as 1MB because it's a "fork" of torvald's |
| 15:22.46 | zenitraM | GitHub does not have any hard storage limits. We have soft limits for each plan to prevent abuse. We find almost everyone uses a small fraction of this limit. If you find yourself needing more disk space for a legitimate use, email support@github.com. |
| 15:22.47 | zenitraM | :) |
| 15:24.32 | mnemoc | just went to the billing page where the current plan is shown but no word about what "soft limit" applies to me :| |
| 15:25.18 | mnemoc | only that I can make 2 more private repos :p |
| 15:26.28 | zenitraM | probably the soft limits are hidden and only triggered on.. way too much space |
| 15:26.38 | mnemoc | yes |
| 15:26.53 | zenitraM | i have 5 private repos (free micro account with student email :P) |

| 19:44.45 | specing | You could also switch to c++ |

| 19:45.54 | specing | I seem to have both script.bin and script0.bin, which one is relevant? |
| 19:50.58 | specing | Ah nevermind, they are identical |
| 19:56.13 | mnemoc | I don't do C++, or java or php. ever |
| 19:56.23 | mnemoc | script0.bin is a backup |
| 19:57.30 | mnemoc | specing: if you want to help the purpse of bin_size is to validate the offsets to not jump out of the mmap |
| 19:58.05 | mnemoc | specing: and next pending check is to see if there are gaps in the blob |
| 20:01.59 | specing | Why not C++? What did it do to you? |
| 20:07.35 | specing | I find your code unreadable spaghetty :( |
| 20:07.46 | mnemoc | :< |
| 20:07.50 | specing | :) |
| 20:10.47 | mnemoc | i'm aware of the lack of comments problem... but from there to unreadable spaghetti |
| 20:11.22 | mnemoc | reading function by function from bottom up show be simple enough |
| 20:13.17 | mnemoc | but I've been writting C since I'm 10 so what's obvius for me it's not necessarily clear for everyone |
| 20:17.30 | specing | You are also using gotos ... :( |
| 20:18.31 | specing | Couldn't you make usage a function? .. like the rest of the world does? |
| 20:20.24 | mnemoc | in many cases I do... but there the usage string is part of the fail flow |
| 20:21.19 | mnemoc | gotos are only on the main() when validating the arguments |
| 20:25.26 | mnemoc | warnings gone |

| 21:12.14 | specing | It probably goes though some kind of an amplifier |
| 21:12.24 | specing | the damn thing draws a watt at 3.3V |
| 21:13.21 | zenitraM | my electronics knowledge is severely lacking |
| 21:13.35 | zenitraM | but... shouldn't it work if it's still 3.3V? |
| 21:14.02 | specing | Most MCUs I know can't put out more than 20mA on a pin |
| 21:14.16 | specing | And MCUs are designed to be "sufficient" |
| 21:14.22 | specing | While MPUs.... |
| 21:14.38 | specing | i seriously doubt it can put out more than 3mA on a pin |
| 21:15.05 | specing | It probably goes through a darlington |
| 21:16.25 | zenitraM | idk what's that, but if it the rise/fall times are fast enough... shouldn't it work? |
| 21:16.36 | zenitraM | (unless on/off is reversed) |
| 21:17.07 | specing | I think it should do 115200 |
| 21:17.07 | zenitraM | and... those are chinese chips. don't assume *anything* from china. |
| 21:17.21 | zenitraM | there's just one way to find out :) |
| 21:17.35 | specing | mnemoc: fex2bin produces a 0 byte file |
| 21:18.08 | mnemoc | specing: as I said before, fex2bin is not finished :) |
| 21:18.27 | mnemoc | specing: but there is a closed source one hanging on the wiki |
| 21:19.34 | mnemoc | currently it only reads the lines and removes heading and trailing whitespace |
| 21:19.48 | zenitraM | use the script tool |
| 21:50.58 | *** join/#arm-netbook Faqtotum (ad0b7da2@gateway/web/freenode/ip.173.11.125.162) |
| 21:53.17 | Faqtotum | mnemoc, hno: google search pulled up http://ibot.rikers.org/%23arm-netbook/20120327.html.gz where you guys talked about the allwinner a10; either of you available for a little help |
| 21:53.20 | Faqtotum | ? |
| 21:54.38 | mnemoc | just greet (*cough*) and ask your question and someone may answer it |
| 21:57.37 | Faqtotum | i connected the microsd to serial and got a kernel log from aosp ics after changing script.bin, but no output from uboot. i figured console needs to be redirected to serial in the uboot env in nandb, but i need a new crc, and idk how to come up with one it will like |
| 21:59.01 | mnemoc | what uboot are you using? |
| 21:59.25 | Faqtotum | the stock binary in the vendor ics rom for the moment |
| 22:00.02 | Faqtotum | but after i verify that i can interact with it over serial, i will build a replacement |
| 22:00.30 | mnemoc | Faqtotum: use the one on hno's github |
| 22:00.54 | Faqtotum | this one uses the boot.axf/boot0/boot1, but the replacement should come straight from brom |
| 22:01.26 | mnemoc | hno: ---^ |
| 22:01.34 | Faqtotum | mnemoc: i intend to, after i verify that i can interact with it over serial |
| 22:02.51 | Faqtotum | the new uboot, after i can interact with this one, will need to be able to boot both android from nand and a linux kernel from nand |
| 22:03.11 | Faqtotum | not from the same nand image, of course |
| 22:05.06 | mnemoc | the safe way is to point to the serial-capable uboot in nanda\linux\linux.ini .... hno's supports boot.scr but I actually don't know if it supports nand |
| 22:05.33 | Faqtotum | btw, where does uboot expect the console if it's not redirected to serial in the env? |
| 22:05.40 | mnemoc | hipboi's (also in github) doesn't support boot.scr but one of his branches supports nand |
| 22:06.16 | mnemoc | i don't know, wait for hno |
| 22:06.23 | hno | me? |
| 22:06.30 | Faqtotum | sorry, my expertise is a bit spotty: what exactly is boot.scr? |
| 22:06.54 | hno | reads backlog |
| 22:06.56 | mnemoc | Faqtotum: a file to "script" your boot |
| 22:07.07 | Faqtotum | which stage? |
| 22:07.14 | mnemoc | uboot |
| 22:07.20 | Faqtotum | ah |
| 22:07.26 | mnemoc | you tell uboot on a file what to do |
| 22:07.38 | mnemoc | instead of hardcoded or interactive |
| 22:07.41 | Faqtotum | i'm looking earlier in the process atm |
| 22:07.56 | Faqtotum | and i need interactive for now |
| 22:08.31 | hno | the stock uboot should use sd serial when told by script.bin |
| 22:09.22 | hno | the mmc one don't. |
| 22:09.34 | Faqtotum | well, it doesn't |
| 22:09.49 | hno | odd |
| 22:09.57 | Faqtotum | from what i can tell, it has to be told in the env |
| 22:10.16 | Faqtotum | i.e. nandb |
| 22:10.42 | hno | I doubt. It is the same seriakl port, just different A10 pin configuration. |
| 22:11.32 | Faqtotum | i figured i need to add "stderr=serial" "stdout=serial" "stdin=serial" to the uboot env |
| 22:12.02 | Faqtotum | the existing env does not have that |
| 22:12.14 | hno | that might explain things. |
| 22:12.21 | Faqtotum | yes |
| 22:12.38 | Faqtotum | that's why i need to put it in nandb first |
| 22:12.42 | Faqtotum | so, how? |
| 22:13.12 | Faqtotum | and where does it put console if that's not in the env? |
| 22:16.01 | hno | good question. Never looked into that. |
| 22:16.38 | Faqtotum | well, that last part doesn't really matter, as long as i can get serial from uboot |
| 22:16.41 | *** join/#arm-netbook Xlab (~Adium@85.26.155.102) |
| 22:21.50 | Faqtotum | so, do you normally deal with nandb's with "stderr=serial" "stdout=serial" "stdin=serial" already in them? |
| 22:22.03 | Faqtotum | hno: ^ |
| 22:25.45 | hno | have a mele with console port, and stock u-boot configured to use it. |
| 22:26.14 | Faqtotum | configured in the env? |
| 22:27.02 | hno | no idea, have not really bothered to look into stock system much. Normally boot from sd. |
| 22:27.43 | Faqtotum | booting from sd is not an option here, because the serial is over sd |
| 22:27.54 | Faqtotum | i have to use nand |
| 22:28.15 | hno | but i do know that I have the stock u-boot console. |
| 22:28.59 | Faqtotum | can you please take a look in your env nand block? |
| 22:30.05 | hno | not tonight. mele currently disconnected, and only one hand free. |
| 22:30.16 | Faqtotum | ah |
| 22:30.37 | Faqtotum | you don't have an image of your nand? |
| 22:30.48 | hno | no |
| 22:31.02 | zenitraM | Faqtotum: you need to recompile the non-mmc u-boot for it to output where script.bin says |
| 22:31.16 | zenitraM | if you search around the logs, hipboi told me how to do it here |
| 22:31.39 | Faqtotum | zenitraM: got URL? |
| 22:32.31 | zenitraM | http://ibot.rikers.org/%23arm-netbook/20120228.html.gz |
| 22:33.03 | zenitraM | although one more line is missing - wtf is <PROTECTED>? |
| 22:34.35 | zenitraM | anyway, the problem is that u-boot doesn't read the configuration on script.bin but writes to a hardcoded location for uart (the original one) |
| 22:42.03 | Faqtotum | do you have the protected line in your logs? |
| 22:42.23 | mnemoc | isn't it easier to just replace the included u-boot and if it doesn't work re-flash the device? |
| 22:45.44 | Faqtotum | is there ANY nand-booting uboot that could output serial over sd? |
| 22:46.14 | Faqtotum | zenitraM: ^ |
| 22:46.52 | zenitraM | Faqtotum: in compiled form, none |
| 22:47.22 | zenitraM | i have no logs here (or the sources for that fact), i had a HD crash on the meantime |
| 22:47.31 | zenitraM | *sigh* |
| 22:48.04 | Faqtotum | compileable source is fine |
| 22:48.05 | mnemoc | zenitraM: what day/timerage of logs you need? |
| 22:48.36 | zenitraM | 2012/02/28 |
| 22:48.46 | zenitraM | what hipboi said at.. 12:18.58, no idea of which timezone |
| 22:49.01 | zenitraM | for some reason the logbot decided to log <PROTECTED> instead of the line of code |
| 22:49.07 | mnemoc | zenitraM: we are on the same zone |
| 22:49.12 | Faqtotum | rikers.org time, whatever that is |
| 22:49.26 | zenitraM | mnemoc: i know, but the bot might not be :P |
| 22:52.02 | zenitraM | mnemoc: stop searching |
| 22:52.14 | zenitraM | hipboi added it here: http://git.hands.com/?p=u-boot.git;a=commit;h=f501a2cfd78fc65eed26c408159acef7e8f1a9b9 |
| 22:52.50 | mnemoc | the only code I see taht day is http://dpaste.com/742972/ |
| 22:53.25 | zenitraM | that's it, the second line |
| 22:53.51 | zenitraM | but tom commited it later, in fact now lichee-dev u-boot will output correctly |
| 22:53.58 | zenitraM | Faqtotum: get and compile this u-boot: http://git.hands.com/?p=u-boot.git;a=tree;h=refs/heads/lichee-dev;hb=refs/heads/lichee-dev |
| 22:54.00 | mnemoc | btw, my uboot repo keeps a mirror of hipboi's if you prefer github's ui |
| 22:54.21 | mnemoc | I do :p |
| 22:54.34 | zenitraM | nice to know :P |
| 22:56.43 | Faqtotum | it was "protected" because the line started with a space |
| 22:57.31 | Faqtotum | zenitraM: will that boot from nand, though? |
| 22:57.58 | zenitraM | it should |
| 22:58.18 | zenitraM | the one that boots from mmc is lichee-dev-mmc |
| 22:58.50 | zenitraM | just replace the u-boot.bin and everything *should* work, but this time with logging |
| 22:58.58 | Faqtotum | i will try |
| 23:21.03 | zenitraM | o.o |
| 23:21.23 | zenitraM | connecting the sata drive i bought to my macbook using a usb-to-sata adapter... makes the trackpad act wonky |
| 23:21.52 | zenitraM | connected directly or using a hub, both on osx and linux |
| 23:22.45 | zenitraM | aliens. |
| 23:24.38 | Faqtotum | ok, i get output from uboot, but no boot delay to escape boot |
| 23:25.53 | Faqtotum | zenitraM: ^ |
| 23:26.31 | zenitraM | Faqtotum: okay.. so you need to modify the u-boot environment |
| 23:26.42 | zenitraM | to make it delay |
| 23:28.09 | Faqtotum | how? |
| 23:28.19 | Faqtotum | i can't make the crc |
| 23:29.15 | Faqtotum | zenitraM: ^ |
| 23:29.35 | zenitraM | mmm |
| 23:29.53 | zenitraM | there was a tool to alter it in linux |
| 23:30.08 | Faqtotum | zenitraM: got URL? |
| 23:30.25 | zenitraM | apt-get install uboot-envtools |
| 23:47.03 | Faqtotum | zenitraM: that requires an mtd device |
| 23:47.28 | zenitraM | tsk, right |
| 23:47.40 | zenitraM | mmm i don't remember how i did on mine |
