03:03.37chouimatnot for long
03:03.45LyosNorezelheh
03:04.14LyosNorezelany idea on how to hack firmware files?
03:05.35chouimatLyosNorezel beside strings and an hex editors ... I have none
03:05.44LyosNorezeldamn
03:06.00LyosNorezelI found _9_ instances of EF53
03:06.41LyosNorezelwhich any *nix dev should know is ext2's magic number
03:14.41*** join/#edev FireEgl (i=Proteus@2001:5c0:84dc:1:211:9ff:feca:b042)
03:53.50MonMothaLyosNorezel: in that case, go searching for the rest of the ext2 fs header (which may or may not be there - after all, EF53 may be showing up coincidentally)
03:54.11MonMothaif you do find the rest of the table, use the info in it to copy out the whole filesystem to another file, loopback mount it, and see what'st ehre
03:54.37LyosNorezelMonMotha: do you know the rest of the ext2 fs header>?
03:55.13MonMothano, but the kernel source does
03:55.27MonMothaand I think there's some human readable documentation floating around that google knows about
03:55.58LyosNorezelhmmm

15:33.16LyosNorezel2don't know if you got that or not
15:33.18LyosNorezel2;-)
15:35.26T0mWwhy not, I'm that way most of the time.  It is only when I realize it that I get depressed!
15:36.02LyosNorezel2ROFLMFAO
15:36.19LyosNorezel2you should enjoy being an arsehole
15:36.35LyosNorezel2it's alot more fun than being a 'nice guy'
15:36.53T0mWheh
15:37.37prpplagueand from personal experience, will probably get you more chicks too
15:37.55LyosNorezel2ROFLMFAO
15:38.10T0mWyeah, they love it when they have a "project" on their hands
15:40.31sjhillg'day all
15:40.53LyosNorezel2oh great... it's dumping white shit all over the city
15:43.39T0mWLyosNorezel: pigeons?

15:45.53prpplaguesjhill: see you been on a "commit" spree
15:46.47sjhilli'm not done either
15:47.11sjhillstill have the external toolchain patches to go in
15:47.15sjhilltoday or tomorrow for sure
15:47.23LyosNorezel2T0mW: snow
15:47.27sjhilli'm merging my work tree to latest
15:47.32sjhillthen i can make my patch

15:56.51T0mWprpplague: I haven't gotten that far yet.  Customer pulled me off that project a month ago for some other work.
15:57.55T0mWprpplague: he just sent another email this morning begging me to get an 8051 software project written
15:58.45prpplagueT0mW: i meant in general, not specifically with the s3c24xx
15:59.05prpplagueT0mW: the s3c2410 has a max clock of 25mhz for the spi controller
15:59.12T0mWwell
15:59.20T0mWthere are some issues with spi
15:59.31prpplagueT0mW: which without compression i would gather that translates to 25mbps
15:59.34prpplagueT0mW: oh?
15:59.48T0mWit is that the lpc2000 micros don't grab the data that fast.
16:00.05T0mWmaybe you can do it if you run FIQ
16:00.29prpplagueyea, the spi slave device can run up to 120mhz
16:00.45prpplaguereally, all i'm looking for is around 60mhz
16:00.47T0mWdid you add an extra 0?
16:00.49T0mWheh
16:00.54prpplagueno
16:01.54T0mWI'll get back to you on that throughput rate sometime in the future.  Today, I have my doubts that I'll get over a megabit
16:02.01T0mWmb/s
16:02.43T0mWI fully expect to be running down in the 100's of KHz rate
16:04.31prpplagueoh
16:04.49prpplagueT0mW: well, with the enc28j60 i was able to get 12mhz no problem
16:06.08T0mWprpplague: yeah, but that was a hardware mechanism driving the SPI bus.  With the micro you have overhead
16:07.23T0mWprpplague: maybe our intended use of the SPI differ.  I will be using it for a query / response where it will respond to a variety of commands / data blocks
16:08.18prpplagueT0mW: yea, i'm using a dedicated spi device
16:12.52prpplagueT0mW: basically its an 802.11g radio
16:13.05prpplagueT0mW: need to be able to push up to 54mbps thru
16:13.11T0mWheh
16:13.21T0mWROTFL
16:13.40prpplagueT0mW: ?
16:14.00T0mWprpplague: now you know that they ain't gonna get all those bits out onto the RF, right?
16:14.01T0mWheh
16:14.12prpplagueT0mW: ??
16:14.54T0mWI know the number 54mb/s but, anyway, I don't think that it will actually run that fast.
16:15.57T0mWWifi doesn't seem to run that fast does it?
16:15.57prpplagueT0mW: works fine with xscale
16:15.58prpplagueT0mW: running at 600mhz
16:15.58prpplagueT0mW: i get pretty close to 54mbps
16:15.58T0mWok

16:15.58prpplagueT0mW: problem is the spi controller for the s3c24xx only goes up to 25mhz
16:16.05T0mWnod
16:17.42T0mWprpplague: well, how about running two SPI links then?  Use both channels
16:17.56T0mWinterweave the bytes
16:18.40T0mWthat might work if you have access to the code on the wifi unit.
16:20.20T0mWyou know, that at 54mb/s that would mean that you would have 148ns to pump another byte into the SPI TX register?
16:22.35T0mWcul, I got to go to the bank

16:39.27prpplagueT0mW`gone: how did you come up with 148ns ?
16:39.48wmatprpplague: I guess you're not at LCA either?
16:40.08wmatit's 30C there and -20C here
16:40.12prpplaguewmat: guess not since i don't know what LCA is

17:04.21MonMothaprpplague: just btw, the 54mbps is not the IDR on wifi.  That includes all the headers, error correction, etc.
17:04.31MonMothaso you don't actually have to pull off 54

17:05.26MonMotha802.11g might attain perhaps 48Mbps if it's sitting right next to the AP, running in pure G (no B compatibility) mode
17:06.52prpplagueMonMotha: yea, i know that, you know that, but some of these PHB's can't seem to understand that

17:37.24MonMothawell, that's in the literature
17:37.53MonMothaI can (somewhat) understand them not being able to grasp that your application doesn't need to push full 54Mbps in the first place, but that's a known, documented thing
17:38.01MonMothaheck, the chipset datasheet itself probably mentions that
