15:42.03prpplagueat this point in the game, we have a working version of the board with a mmc socket
15:42.16prpplaguebut the SD sockets are too big for the design
15:42.19prpplagueso.....
15:42.29sjhillhacksaw
15:42.32prpplaguewe are stuck with either going with strictly mmc or going with miniSD

15:43.46prpplaguethe miniSD has the same functionality as a regular SD card, just smaller
15:43.55prpplaguethey are a few dollars more expensive
15:44.07pb_yeah, I had a flyer from Hirose the other day that talked about miniSD connectors.
15:44.50pb_they look fine to me.
15:45.52prpplaguepb_: oh yea? got a url for them? i was looking at sockets now
15:46.07pb_www.hirose.com, I think
15:46.10pb_or www.hirose-connectors.com, maybe
15:46.39pb_minisd is their "dm2" series.
15:46.53prpplaguethanks

19:12.26sjhilldo you think we'd would admit it?
19:12.40prpplaguehehe
19:12.57T0mWprpplague: just ask your dumb question, lackey
19:13.04prpplaguehehe
19:13.34prpplaguewhats the variable that references the argument passed to the make command
19:13.36prpplague?
19:14.02prpplaguei.e. "make all" , what would reference the "all" ?
19:14.05kergoth"the argument"?
19:14.06kergothah
19:14.09kergoththats the make _target_
19:14.17kergoththere are a number of variables for the commandline stuff
19:14.23T0mWoh, this was a trick question!
19:14.39sjhill$@
19:14.40prpplaguehehe, i'm terrible at make
19:14.57kergothno, $@ refers to the matching rule
19:15.07sjhill$<
19:15.07kergothi.e if all: otherthing
19:15.10kergothin otherthing:
19:15.12kergoth$@ is otherthing.
19:15.13kergothnot all.
19:15.20kergothprpplague: what exactly are you asking?
19:15.26kergothwhat are you trying to do?
19:16.12prpplaguekergoth: i need to have some different cflags depending on which make target i've issued
19:16.30prpplaguekergoth: better yet, can you just recommend a good makefile howto?
19:16.39prpplaguekergoth: no sense in me pestering you guys
19:16.43T0mWthere is some target dependant var declarations in make
19:16.43kergoththe online documentation on the gnu site is an excellent reference.
19:16.50T0mWinfo make
19:17.14kergothprpplague: there are a number of ways to accomplish that.
19:17.16kergothone is:
19:17.21kergothmytarget: VAR=value
19:17.29kergothwhich causes VAR to be set to 'value' for mytarget
19:17.39kergothbut also, for all of mytarget's dependencies, and anything that depends on mytarget as well
19:17.46kergothso as you can see, it leaks all over the place
19:17.51Crofton_http://www.gnu.org/software/make/manual/make.html
19:17.55kergothyeah
19:18.13prpplaguekergoth: interesting, i thought i tried that, maybe i had a typo
19:18.19kergoththats all you can have
19:18.22kergothmytarget: VAR=value
19:18.23kergoththats it.
19:18.27kergothnothign else
19:18.27T0mWyeah!
19:18.46kergothmytarget: VAR=value .. then, elsewhere.. the real rule for mytarget
19:19.15kergothbut yeah, you need to be quite careful with that.
19:19.27kergothyou could also just conditionally set CFLAGS based on the actual commandline arguments
19:19.34kergoththere are a number of ways to pull off what you're trying to do
19:19.58T0mWyeah, you could include based on target

19:20.02Crofton_Some of which are quite horrorfying ....
19:20.08kergothhehe
19:20.28T0mWagreed
19:20.45T0mWand sometimes you wonder just WTF is happening
19:21.21prpplaguekergoth: yea, i was gonna do conditional on the command line
19:21.24kergothmake has a 'trace' function.
19:21.27kergothquite useful
19:21.30T0mWdoes?
19:21.35kergothif _really_ _really_ _really_ verbose
19:21.45kergothso verbose, that you have to spend a great deal of time trying to make sense of it
19:21.49kergothbut at least it has it
19:24.40T0mWooo! I didn't know about the "override" keyword!
19:25.19kergoththats a useful one, but its rather ugly
19:25.27kergothi try to avoid it unless theres no other way
19:25.33kergotheven so, i mention it on http://www.openembedded.org/cgi-bin/moin.cgi/Buildsystems_2fRulesOfThumb

22:21.35prpplagueSgt-Donan: yes
22:21.47prpplagueSgt-Donan: it is possible to boot on an eeprom from some devices

22:22.35Sgt-Donanok
22:22.40Sgt-Donanbut it's possible ?
22:22.57Sgt-Donanhow does it work ?
22:23.17Sgt-Donana /dev/mtdblock0
22:23.22Sgt-Donanor something ?
22:23.39Sgt-Donanor it's only for flash memory ?
22:24.28prpplagueSgt-Donan: i'm sorry, i'm confused, you said boot, "/dev/mtdblock" implies "boot linux"
22:24.44Sgt-Donanyes sorry
22:25.16Sgt-Donan(i'm french and i don't choose the good words sometimes)
22:25.21prpplagueSgt-Donan: so you want to have linux in an eeprom?
22:25.28Sgt-Donanyes
22:25.38prpplagueSgt-Donan: i don't recall having seen an eeprom that size
22:25.51prpplagueSgt-Donan: why would you want to use an eeprom instead of flash?
22:25.55Sgt-Donani have create a cramfs root filesystem
22:26.22prpplagueSgt-Donan: i don't see you getting a kernel and ramdisk smaller than 2mb
22:26.24Sgt-Donani'm a student a it's a part of my project
22:26.33Sgt-Donani get it :)
22:26.50Sgt-Donan240K the / filesystem
22:27.02Sgt-Donanand 800K for the kernel
22:27.19prpplagueSgt-Donan: ok and bootloader?
22:27.39Sgt-Donani think i get precise an adress
22:27.45Sgt-Donani can
22:28.06Sgt-Donani have the memory mapping of the board
22:28.16prpplagueSgt-Donan: so still the cost of a 1mb eeprom is gonna excedded that of implemmenting a 2mb flash
22:28.28Sgt-Donanyes it's possible
22:28.56Sgt-Donanat my school we have eeprom but not flash
22:29.12prpplagueSgt-Donan: so whats the project?
22:29.37Sgt-Donani have to control 4 axes of a motor
22:29.59Sgt-Donani have to make asservissements
22:30.29Sgt-Donanwith a arm robot
22:30.37prpplagueSgt-Donan: i think you will find, you will spend more time trying to make eeprom work than the minor cost of getting flash
22:30.49Sgt-Donansure
22:31.06Sgt-Donani will ask my professor to get some flash device
22:31.52CosmicPenguinprpplague: what is the shipping policy for canda?
22:31.53Sgt-Donanif i have a flash device i only do a root=/dev/mtdblock0 ?
22:32.01CosmicPenguinDo I need an export license or anything to send a loaner to file?
22:33.09Sgt-Donanthis is my board : http://www.esiee.fr/~info/a2si/Architecture/Kits/40/mvme162lx.html
22:34.12prpplagueCosmicPenguin: no idea, i've never been able to ship anything there, it always get confiscated or returned

22:42.15prpplagueone sec
22:46.34prpplagueSgt-Donan: 28F008SA intel
22:46.45Sgt-Donanok
22:46.56prpplagueSgt-Donan: yea, you can populate the 4 eprom sockets with up to 1mb x 8 chips
22:47.42Sgt-Donanis it possible to split in 2 roms of 512k ?
22:48.01Sgt-Donanor it's very hard ?
22:48.04prpplagueSgt-Donan: i do not under stand what you are asking
22:48.13Sgt-Donansorry :/
22:48.35Sgt-Donanmy kernel and my root filesystem takes ~1M
22:48.49Sgt-Donani have 2 eeprom
22:48.54Sgt-Donanof 512K
22:49.12prpplague512kb x 8 or 512KB ?
22:49.34Sgt-Donan512Kbytes
22:49.52prpplagueok so you have 2 512kb chips?
22:49.58Sgt-Donanyes
22:50.29Sgt-Donanit's possible to split my filesystem and put it on the 2 eeproms ?
22:50.41Sgt-Donanor it's too much complex
22:50.46prpplagueSgt-Donan: will you be running out of flash or in ram?
22:51.16Sgt-Donanrunning out ?
22:51.24prpplagueSgt-Donan: thing is, if you kernel+rootfs is less than 1mb , why not just use the intel flash?
22:51.34prpplagueSgt-Donan: put your bootloader in the eprom
22:51.39Sgt-Donanyes i could
22:51.56Sgt-Donanbut i don't know if i have one
22:52.06Sgt-Donani will look friday
22:52.18Sgt-Donanor tomorrow
22:52.37prpplagueSgt-Donan: all the mvme 162lx series come with 1mb flash according to the datasheet
