15:40.16jbevrenprpplague: did you catch my update on the pixter mm cart?
15:41.12prpplaguejbevren: sorry no
15:42.20prpplagueCosmicPenguin: i really should post my notes for converting from handle_scancode in 2.4 to the input layer in 2.6, there are a ton of people post questions on that
15:42.47jbevrenprpplague: my spongebob uses real ICs heh
15:42.51jbevrenor used.. I depopulated it
15:43.16jbevrenunfortunately, the image is kinda .. large
15:43.25jbevrenso it overlays the navbar
15:43.52jbevrenand the end of the table is for some reason broken in spite of proper formatting characters
15:45.08prpplaguejbevren: yea, are you sure that matrix chip isn't similiar to the nand chip used in the juicebox?
15:45.26jbevrenprpplague: it wouldnt surprise me if it were
15:45.46jbevrenhowever, the pin connections all line up with functions guessed by your expansion slot table for the pixter color
15:45.55prpplaguejbevren: your table is a little hard to read
15:45.59prpplaguejbevren: :P
15:46.01jbevrenheh
15:46.05jbevrenI did note it needs cleaning
15:46.14prpplaguejbevren: what is the exact part number on the chip?
15:46.21jbevren11247-01
15:46.33jbevrenthe rest are batch and version codes
15:47.00jbevrengoogle searches didnt turn up a pdf, but results indicated that its in the 3d memory family
15:47.09jbevrenso I chose another IC from the same family to get the pin assignments
15:49.26prpplaguejbevren: yea thats the same chip as in the juiceboc
15:49.33prpplaguejbevren: thats nand flash not nor
15:50.14prpplaguejbevren: what was confusing you about the info?
15:51.57jbevrenok
15:52.04jbevrenyour table for pins on the xpansion slot,
15:52.12jbevrenit doesnt note which position is pin 1, 2, and 60
15:52.27jbevrenthe spongebob cart is numberd like so:
15:52.28jbevren12
15:52.28prpplaguejbevren: ahh
15:52.29jbevren34
15:52.31jbevren56
15:52.32jbevren(etc
15:52.35prpplaguejbevren: yea i need to update that
15:52.36jbevrenwith the card standing up
15:52.54jbevrenI think yours is numbered counter-clockwise starting on the top left (like most ICs)
15:53.25jbevrenI suggest the numbering be adjusted to match the cart.  I know yours was done that way cause you had no reference (we discussed it previously)
15:53.45prpplagueinteresting, /me is wondering if the same player applicatio is being used on the pixter as on the juicebox
15:53.53jbevrenhum
15:54.01jbevrenthe same init code you mean?
15:54.10prpplaguejbevren: no the same video player
15:54.12jbevrenah
15:54.17prpplaguejbevren: remember the video player is on the chip
15:54.22prpplaguejbevren: not in the device
15:54.22jbevrenI dont think Ive seen video in a cart yet
15:54.36jbevrenright, the playback application is on the cartridge
15:54.45prpplaguejbevren: that spoonge bob cart isn't video?
15:54.57jbevrenthe JB has one internally, but just for the demo
15:54.57jbevrenno, its interactive games
15:54.57jbevrenas was my other one
15:54.58prpplaguejbevren: ahh
15:55.10prpplaguenon the less, that is interesting
15:55.18prpplaguemeans we can use standard xD cards
15:55.25jbevrenso, whats confusing about the table I did (other than all the unnecessary info?)
15:55.26jbevrenhehe
15:55.29jbevrennod
15:55.37jbevrenor 3.3v smartmedia heh
15:55.55jbevrenif you look at the loop on vcc
15:56.00prpplaguejbevren: the table displayed a little funky
15:56.08jbevrenI suspect its pulling a pin high to indicate the type of boot flash in the card
15:56.16jbevrenprpplague: widen your browser maybe.
15:56.34jbevrennaw if I narrow it just overlays the navbar
15:56.37prpplaguejbevren: one sec
15:56.47jbevrenthere are empty spaces in the 7432 table that should be there
15:56.57jbevrenbut the third section (more rom/misc) wont format properly for me :(
15:59.20prpplaguejbevren: have a look now, i did a couple of lines
16:00.18jbevrenheh
16:00.20jbevrensure, be fancy :)
16:00.28jbevrenthe table looks like that cause it was made in vi, originally
16:00.53jbevrenmy luck with moinmoin's editing codes is less than stellar heh
16:01.10prpplaguejbevren: hehe yea, it took me awhile
16:08.13prpplaguejbevren: make sure you update the info for the chip as well, its nand
16:08.26jbevrenso nor is the run-in-place type of memory?
16:08.35jbevrenI think they should just use terms that make effin sense
16:08.36prpplaguejbevren: you could also add a note stating its the same as what is used in juicebox
16:08.36jbevrenlike
16:08.41jbevrenlinear flash
16:08.43jbevrenvs banked flash
16:08.44jbevren:)
16:09.04prpplaguejbevren: NOR and NAND describe the method of latching the data internally
16:11.05jbevrenand theyre used to define the method of storage (banked vs linear as noted) heh
16:11.12jbevrenI care little about the internal operation of the IC :)
16:11.27jbevrentheyre the chip manufacturer, not me :)
16:12.59prpplaguejbevren: agreed, however the classification of NOR and NAND are significant in the method of software used to access them
16:13.06jbevrenhow do I insert an empty cell?
16:13.28prpplaguejbevren: just do some like || ||
16:13.32prpplaguejust a space
16:13.36jbevrendoesnt work
16:13.48prpplagueyou sure?
16:14.31prpplaguehmm, guess i always used either N/A or N/C
16:16.55jbevrenbtw |||| makes it span a cell over two col's
16:17.26jbevrenjust in case you ever need to do so :)
16:21.12prpplagueahh
16:21.31prpplaguejbevren: saved it yet?
16:22.11jbevrensubmitted just now
16:22.58jbevrensigh
16:23.07jbevrena few weeks ago, walmart had pixter MM's on clearance for 20 bucks
16:23.14prpplaguejbevren: yea i heard
16:23.24jbevrenI should have got a couple so I could depopulate one to trace the lines from the expansion port
16:23.25prpplaguejbevren: thats why there are alot on ebay, hehe
16:23.30prpplaguejbevren: hehe
16:23.33jbevren:)
16:23.40jbevrenhave heatgun, will burn IC's off boards
16:23.43jbevrenmwahaha :)
16:23.43prpplaguejbevren: ok so how are you numbering the pins?
16:23.47jbevrenok
16:23.54jbevrenif you examine the composite image at the top of the page
16:24.01jbevrenyou see that the primary side of the pcb has odd numbered pins
16:24.04prpplagueodd on one side, even on the other?
16:24.09jbevren1 3 5 -- 59
16:24.11jbevrenright
16:24.17prpplagueahh ok
16:24.20jbevrenthe secondary side is numbered 2 4 6 -- 60
16:24.32jbevrenhttp://www.jbevren.net/pixter/spongebob-front.jpg
16:24.37jbevrenhttp://www.jbevren.net/pixter/spongebob-rear.jpg
16:25.02prpplaguejbevren: see crt:2 on your chart is pin 30 on mine
16:25.04jbevrenI ruined the board while depopulating it, so I cant remount the rom IC
16:25.14jbevrenah
16:25.20jbevrenyou number in a reverse N layout?
16:25.28jbevren1 30
16:25.29jbevren2 31
16:25.35prpplagueyea looks that way
16:25.39jbevren29 60
16:25.40jbevrenk
16:25.48prpplaguei'll probably update my table
16:25.58jbevrengoing to match the card?
16:27.28prpplaguejbevren: yea thats probably the best thing to do
16:27.34jbevrenok
16:27.50jbevrensend me a note when you do, I'll strip the 'wiki pin' column off those tables ;)
16:28.10prpplagueokie dokie
16:28.21prpplaguei bet we could get linux running on it in no time
16:28.28prpplagueeven add the usb slave
16:28.52jbevrenheh
16:29.03jbevrenoh.. I -finally- put some 51R resistors on order
16:29.05jbevren;)
16:29.15jbevrenso maybe I can jtag the thing without locking it up
16:29.35prpplaguejbevren: ??
16:29.48jbevrenmy jtag is a wiggler built on a prototype plugboard
16:29.49prpplaguewhatcha need 51R resistors for?
16:29.55jbevrenoutput impedance matching
16:30.01jbevrenI guess
16:30.18prpplaguethat sounds odd, what kind of dongle are you using?
16:30.24jbevrenthe adapter is built like so : paraport -> buffer -> 51R -> device
16:30.31jbevrenits a wiggler as described on sf.net
16:30.53jbevrenhttp://jtag-arm9.sourceforge.net/circuit.txt
16:30.56prpplaguejbevren: url?
16:31.11jbevrenat any rate, I tried without the resistors, but boundary-scanning the pixter like that crashes it
16:31.16jbevrenand a second boundary scan comes up null
16:31.53prpplaguejbevren: oh so you are building the jtag adapter
16:31.56jbevrenright
16:32.01prpplagueahh gotcha
16:32.15jbevrenI'm using a 74alvc244 bus driver for level shifting and buffering

17:00.56prpplagueCosmicPenguin: my right index finger has been tingly at the tip for a week now :(
17:01.12CosmicPenguinmaybe you should just stop sticking it in a light socket
17:02.21prpplagueor my nose
17:04.41jbevrenprpplague: did you pop some ibuprofen as I suggested?
17:05.10prpplaguejbevren: yea, doesn't seem to be helping
17:08.13jbevren:(
17:08.20jbevrenvisit el doctor then :(
17:08.26jbevrenbetter to catch it early

20:56.53jbevrenthe sd card was gone but I dont care :)
21:01.11jbevrenheh
21:01.15jbevrenstupid windows
