17:36.23 | prpplague | drath: ping |
17:36.29 | prpplague | drath: give me a shout when you can |
18:26.37 | drath | hey prpplague |
18:28.15 | prpplague | drath: i know you stay pretty busy these days, but we are starting work on a new jtag device for use with openocd, any interest in having us send you and early rev of the unit? |
18:35.13 | drath | yeah, would be great - can you disclose any details already? |
18:39.53 | prpplague | yea, let me message you |
18:47.42 | prpplague | drath: check your /msg when you have time |
21:38.54 | key2 | prpplague: you told me there are a lot of sch available with S3C2440, you know where I could find some ? |
21:39.22 | prpplague | key2: littlechips.com and the smdk2440 boards are both available for schematics |
21:39.37 | key2 | thx |
21:40.10 | prpplague | iirc the embest boards are available as well - http://www.armkits.com/Product/sbc2440-II.asp |
21:40.20 | prpplague | key2: doing a 2440 design? |
21:40.53 | key2 | yeah |
21:41.10 | prpplague | you done bga work before? |
21:44.19 | key2 | prpplague: well am not gonna solder it myself |
21:44.32 | prpplague | key2: i mean the pcb layout |
21:44.44 | key2 | mmh |
21:44.52 | key2 | not much, but achiestdragon is helping |
21:44.55 | key2 | prpplague: why ? |
21:45.16 | prpplague | the layout on the s3c2440 is very tight and does require impedence matching |
21:45.28 | prpplague | key2: mind if i ask what you guys are working on? |
21:45.41 | prpplague | key2: i might be able to help with some info |
21:45.55 | key2 | prpplague: doing an IP phone |
21:46.05 | key2 | prpplague: the shit is that they put all the data line in the middle of the chip |
21:46.09 | key2 | instead of gnd/vcc |
21:46.56 | prpplague | key2: going to do all of the processor/flash/memory one board , or do a module just for the cpu section? |
21:47.13 | key2 | prpplague: am thinking about one board |
21:47.17 | key2 | would be cheaper |
21:47.57 | prpplague | cheaper for production, but i can tell you from experience, prototype/early revs are going to eat your lunch |
21:48.23 | prpplague | key2: have you done a proof-of-concept yet? |
21:48.33 | key2 | prpplague: is it possible to route it on 4 layers ? |
21:48.37 | key2 | prpplague: you've done it ? |
21:49.04 | key2 | prpplague: i tried with one of those: http://cgi.ebay.com/Samsung-S3C2440-ARM9-Board-7-TFT-LCD-w-Touch-Panel_W0QQitemZ120300548725QQihZ002QQcategoryZ55824QQssPageNameZWDVWQQrdZ1QQcmdZViewItem |
21:49.07 | prpplague | key2: not on 4, 6 will be hard, 8 is more likely the middle ground |
21:50.05 | prpplague | key2: yea that is a decent board, but it has everything wired up so to speak |
21:50.32 | key2 | prpplague: the thing is that the dude that made this one made it on 4 layers !!! |
21:50.56 | prpplague | yea fairly big board too |
21:51.06 | key2 | well I have 150x100 |
21:51.16 | prpplague | i assume thats mm |
21:51.30 | key2 | yeah |
21:51.31 | key2 | ;) |
21:51.44 | prpplague | that pretty darn big |
21:51.51 | prpplague | this is suppose to be a handheld device? |
21:51.52 | key2 | its for a touchscreen phone |
21:51.53 | key2 | :) |
21:52.01 | key2 | desktop ip phone |
21:52.02 | key2 | ;) |
21:52.10 | key2 | not a cellphone |
21:52.21 | prpplague | ahh not cellphone type |
21:52.29 | key2 | noo |
21:52.32 | key2 | a desktop IP phone |
21:52.45 | prpplague | what kind of Z space have you got ? |
21:52.54 | key2 | hat u call Z space ? |
21:53.02 | key2 | s/hat/what |
21:53.16 | prpplague | height |
21:53.25 | prpplague | above the pcb |
21:53.59 | key2 | well the PCB will be right under the touchscreen, and both will be let say at 45deg from the table |
21:54.12 | prpplague | ahh |
21:54.28 | key2 | you have something that is 150mm and 45deg :) |
21:55.03 | key2 | http://88.191.12.21/phone/IMG_0064.jpg |
21:55.46 | prpplague | key2: personal recomendation, take it for you will, if it were mean, i'd find a good s3c2440 cpu board, design the first rev of the board using the module, just leave the area on the pcb where you want to eventually put the cpu/flash/sdram, once you have the i/o completed and working rev the board with the cpu on it |
21:55.51 | prpplague | looks |
21:55.53 | key2 | prpplague http://88.191.12.21/phone/IMG_0053.jpg |
21:56.16 | prpplague | dandy looking device |
21:56.22 | prpplague | gui is really nice |
21:56.47 | key2 | prpplague: it's using the Winamp rendering engine |
21:56.57 | key2 | the guy that did winamp is helping... |
21:57.01 | prpplague | that neat, i'm more of kernel person soooo |
21:57.09 | key2 | yeah same here |
21:57.29 | prpplague | key2: http://www.armkits.com/Product/SBC2440-III.asp |
21:57.39 | prpplague | key2: the same folks that you got your kit from |
21:57.46 | prpplague | key2: but the cpu section is on a module |
21:58.08 | prpplague | key2: you should really think about using that for the first few revs of the design |
21:58.14 | key2 | prpplague: http://www.yctek.com/news/view_49.html |
21:58.15 | key2 | you mean this ? |
21:59.07 | prpplague | i can;t read that, but it looks the same |
21:59.58 | key2 | yctek is the company that makes it |
21:59.58 | key2 | yeah |
22:00.48 | key2 | prpplague: is it MII or RMII ? |
22:00.51 | key2 | for the PHY |
22:01.42 | prpplague | sorry don't know the specs that well |
22:01.50 | key2 | k |
22:01.51 | prpplague | for those boards |
22:01.57 | prpplague | we generally do our own |
22:02.17 | key2 | the s3c2440 doenst have a MAC core ? |
22:02.23 | prpplague | http://www.elinux.org/M8050 |
22:02.26 | prpplague | key2: no |
22:02.35 | prpplague | key2: no mac or phy |
22:02.47 | key2 | its your design ? |
22:02.57 | prpplague | yea |
22:03.01 | prpplague | s3c2440 based |
22:03.01 | key2 | wow |
22:03.05 | key2 | not bad :) |
22:03.27 | key2 | prpplague: its a phone ? |
22:03.33 | prpplague | industrial pda |
22:04.08 | key2 | k |
22:04.18 | key2 | and you used one of those module for prototyping ? ;) |
22:04.45 | prpplague | we designed our own module to assist in prototyping different devices |
22:05.08 | prpplague | http://www.elinux.org/JackHammer_Board |
22:05.28 | prpplague | not very good pics, and they don't give you an idea of the size |
22:05.54 | prpplague | they are 50x64mm |
22:08.36 | prpplague | key2: currently we have 4 devices based on the s3c2440, and another 4 or 5 in the works |
22:09.51 | key2 | you dont sell those proto board |
22:09.53 | key2 | do u ? ;) |
22:10.37 | prpplague | not currently |
22:10.59 | prpplague | there was some discussion about selling them, but i'm not sure where that is at the momment |
22:11.37 | key2 | k |
22:11.46 | prpplague | we have a number of s3c2410 boards that are available, but none of the s3c2440 items |
22:12.02 | prpplague | if you want to check with me tomorrow, i'll see if can ask management about them |
22:12.06 | key2 | well S3C2440 is more worth than 2410 |
22:12.19 | key2 | about S3C2440 ? |
22:12.49 | prpplague | yea, i'll ask about the s3c2440 boards |
22:12.53 | prpplague | aka M8010 |
22:12.56 | key2 | k |
22:12.59 | key2 | that would be cool |
22:19.23 | key2 | http://youtiyou.com/S3C2440.aspx |
22:19.27 | key2 | same here I think |
22:20.02 | key2 | http://youtiyou.com/Documents/core2440.pdf |
22:21.01 | prpplague | yea pretty close |
22:21.10 | prpplague | we are using 80 pin connectors |
22:21.16 | prpplague | looks like they are using 84 pin |
22:22.10 | prpplague | heads home for the day |
