| 15:17.37 | juanpaul | Has someone got information about Marvell devices? |
| 15:17.52 | sn9 | what kind of info? |
| 15:18.14 | p2-mate | what kind of device ? |
| 15:18.49 | sn9 | what kind of someone? ;-> |
| 15:19.39 | juanpaul | 88w8510 / 88w8515 |
| 15:20.01 | juanpaul | datasheets, or, at least jtag ports |
| 15:20.21 | sn9 | there is no real standard on the ports |
| 15:20.44 | sn9 | how many pins is it? |
| 15:22.37 | juanpaul | this is a site that trying access a device with Marvell SoC: http://www.bitsum.com/images/wl530g_connectors.jpg |
| 15:22.45 | juanpaul | http://www.bitsum.com/openwiking/owbase/ow.asp?WL-530G |
| 15:24.04 | sn9 | that is the weirdest jtag connector i have ever seen |
| 15:24.10 | juanpaul | i don't have the device with me from now, but, theres a place that appears to be for jtag, the pins are connected to the same side of this pic |
| 15:25.14 | juanpaul | the device that i have is a Edimax EW-7203APg that uses 88w8515 |
| 15:25.34 | juanpaul | the serial connector is correct |
| 15:31.48 | juanpaul | ? |
| 15:34.17 | sn9 | looking... |
| 15:35.37 | juanpaul | ok, thanks |
| 15:45.45 | sn9 | if you can read chinese, http://www.icpdf.com/PdfView.asp?id=1389151_842850 |
| 15:48.53 | sn9 | but without the pins of the SoC visible, i don't know what help the datasheet would be |
| 16:25.09 | juanpaul | hello, i'm getting login page |
| 16:25.57 | sn9 | yes, and the login page is in chinese |
| 16:26.17 | sn9 | if you can read it, you coiu |
| 16:26.29 | sn9 | if you can read it, you could register and download |
| 16:26.50 | sn9 | the pdf is probably in english |
| 16:27.16 | sn9 | i found no other download for a datasheet |
| 16:28.05 | juanpaul | you have downloaded that datasheet? |
| 16:28.09 | sn9 | no |
| 16:28.26 | sn9 | if i had, i might have posted it somewhere |
| 16:33.32 | juanpaul | here i find the only "datasheet" appears more like and ADS... from Marvell, there in many places on the net: http://hitmen.c02.at/files/docs/psp/Libertas_88W8000G_88W8510.pdf |
| 16:33.42 | juanpaul | from this site: http://hitmen.c02.at/html/psp_docs.html |
| 16:34.38 | sn9 | dunno |
| 16:34.45 | juanpaul | this "datasheet" has 158 KB, seems to be equal the datahseet on the chinese site thata, announces have 161 KB |
| 16:34.55 | sn9 | oh, never mind then |
| 16:36.17 | p2-mate | I don't think there are public datasheets on marvell components |
| 16:37.15 | juanpaul | the true is: "NEVER buy an device with a Marvell component" |
| 16:37.35 | sn9 | it's not so bad |
| 16:38.12 | juanpaul | but they don't deleivery any technical information about the devices... |
| 16:39.24 | juanpaul | I'm trying to contact someone that represents Marvell here in Brazil, trying to get technical datasheet, but isn't easy... |
| 16:41.19 | sn9 | like i said before: |
| 16:41.26 | sn9 | but without the pins of the SoC visible, i don't know what help the datasheet would be |
| 16:42.40 | sn9 | i will be jtagging a marvell board myself within the next day or two |
| 16:43.04 | sn9 | datasheets? we don't need no stinkin' datasheets! |
| 16:43.26 | juanpaul | so, that "datasheet" (if we can claim that a datasheet) isn't a technical datasheet, it's like a "promote datasheet" |
| 16:43.34 | sn9 | yes |
| 16:44.45 | juanpaul | what device you have (and what are the marvell chipset)? |
| 16:44.51 | sn9 | the marvell device i will jtag is the AirLink101 AR625W |
| 16:45.22 | sn9 | i do not know exactly which marvell SoC it has because it's under a heatsink |
| 16:45.30 | juanpaul | ok |
| 16:45.43 | juanpaul | the most common is the 88w8510 |
| 16:46.24 | sn9 | it reports itself as ARM926EJ-Sid |
| 16:46.35 | juanpaul | if i remeber, i don't now any other device (except ew-7203apg) that uses 88w8515.... |
| 16:47.08 | juanpaul | it's reports that information, where? |
| 16:47.36 | sn9 | dmesg |
| 16:47.57 | sn9 | at least, before i accidentally overwrote u-boot, that is |
| 16:48.09 | sn9 | (over serial) |
| 16:48.26 | sn9 | it said: Machine: MV-88fxx81 |
| 16:48.39 | sn9 | but that's the board |
| 16:48.59 | juanpaul | humm... mine, over serial only reports eCos OS and some more thing that i don't remember now... |
| 16:49.14 | p2-mate | it runs ecos ? funny |
| 16:49.21 | juanpaul | yes |
| 16:49.23 | sn9 | eCos? interesting |
| 16:49.31 | juanpaul | and yours? |
| 16:49.35 | sn9 | linux |
| 16:50.03 | sn9 | does asus have a source download for the eCos they used? |
| 16:53.18 | juanpaul | appears that Asus WL-530G runs linux |
| 16:54.40 | juanpaul | here some information: http://www.bitsum.com/openwiking/owbase/ow.asp?WL-530G#h24 |
| 16:55.35 | juanpaul | if you have looked at that datasheet we find, there's information about jtag (information that the device have a jtag port) |
| 16:56.01 | sn9 | that does not mean the board supports it |
| 16:57.01 | juanpaul | not, but my board have 10 ~ 14 terminals left that appears to be the jtag port |
| 16:58.36 | juanpaul | and the terminal become from the same side (side of the least pins of IC), there are so many chances that pins are the jtag pins... |
| 16:59.19 | juanpaul | how i can find it (some voltage level or frequency) that i can find with my multimeter? |
| 17:02.47 | *** join/#openjtag p2-mate (n=p2@cable-87-244-173-194.upc.chello.be) |
| 17:03.46 | sn9 | you need to trace which contact goes to which pin on the SoC |
| 17:04.16 | sn9 | since the pins are not visible, you can't do that |
| 17:05.08 | juanpaul | there's some alternative mode? |
| 17:05.17 | sn9 | i don't know |
| 17:05.27 | p2-mate | you can use some trial and error |
| 17:05.50 | juanpaul | some signaling that can be found with the osciloscope |
| 17:05.58 | sn9 | right |
| 17:06.32 | juanpaul | okay, but what device i select to use with openjtag? |
| 17:09.28 | juanpaul | what cpu |
| 17:12.37 | sn9 | use openocd |
| 17:12.51 | sn9 | not "openjtag" |
| 17:13.14 | sn9 | i have to leave now |
| 17:16.13 | drath | the Marvell Feroceon is a modified ARM926EJ-S |
| 17:16.52 | drath | the guys from #linkstationwiki have been able to flash their target, but debugging didn't work reliably |
| 17:18.17 | p2-mate | drath: I have been told it's a marvell implementation of the armv5 arch ? |
| 17:22.45 | drath | p2-mate: yeah. apparently it's based on the arm926ej-s, and still identifies itself as one, but i read something about a variable length pipeline |
| 17:25.35 | drath | i tried to get some information, but they wouldn't even let me sign an nda |
| 17:25.52 | p2-mate | typical :P |
