Aug 05 15:17:31 <juanpaul> Has someone got information about Marvell devices?
Aug 05 15:17:46 <sn9> what kind of info?
Aug 05 15:18:08 <p2-mate> what kind of device ?
Aug 05 15:18:43 <sn9> what kind of someone? ;->
Aug 05 15:19:33 <juanpaul> 88w8510 / 88w8515
Aug 05 15:19:55 <juanpaul> datasheets, or, at least jtag ports
Aug 05 15:20:15 <sn9> there is no real standard on the ports
Aug 05 15:20:38 <sn9> how many pins is it?
Aug 05 15:22:31 <juanpaul> this is a site that trying access a device with Marvell SoC: http://www.bitsum.com/images/wl530g_connectors.jpg
Aug 05 15:22:39 <juanpaul> http://www.bitsum.com/openwiking/owbase/ow.asp?WL-530G
Aug 05 15:23:58 <sn9> that is the weirdest jtag connector i have ever seen
Aug 05 15:24:04 <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
Aug 05 15:25:08 <juanpaul> the device that i have is a Edimax EW-7203APg that uses 88w8515
Aug 05 15:25:28 <juanpaul> the serial connector is correct
Aug 05 15:31:42 <juanpaul> ?
Aug 05 15:34:11 <sn9> looking...
Aug 05 15:35:31 <juanpaul> ok, thanks
Aug 05 15:45:39 <sn9> if you can read chinese, http://www.icpdf.com/PdfView.asp?id=1389151_842850
Aug 05 15:48:47 <sn9> but without the pins of the SoC visible, i don't know what help the datasheet would be
Aug 05 16:25:03 <juanpaul> hello, i'm getting login page
Aug 05 16:25:51 <sn9> yes, and the login page is in chinese
Aug 05 16:26:11 <sn9> if you can read it, you coiu
Aug 05 16:26:23 <sn9> if you can read it, you could register and download
Aug 05 16:26:44 <sn9> the pdf is probably in english
Aug 05 16:27:10 <sn9> i found no other download for a datasheet
Aug 05 16:27:59 <juanpaul> you have downloaded that datasheet?
Aug 05 16:28:03 <sn9> no
Aug 05 16:28:20 <sn9> if i had, i might have posted it somewhere
Aug 05 16:33:25 <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
Aug 05 16:33:36 <juanpaul> from this site: http://hitmen.c02.at/html/psp_docs.html
Aug 05 16:34:32 <sn9> dunno
Aug 05 16:34:39 <juanpaul> this "datasheet" has 158 KB, seems to be equal the datahseet on the chinese site thata, announces have 161 KB
Aug 05 16:34:49 <sn9> oh, never mind then
Aug 05 16:36:10 <p2-mate> I don't think there are public datasheets on marvell components
Aug 05 16:37:09 <juanpaul> the true is: "NEVER buy an device with a Marvell component"
Aug 05 16:37:29 <sn9> it's not so bad
Aug 05 16:38:06 <juanpaul> but they don't deleivery any technical information about the devices...
Aug 05 16:39:18 <juanpaul> I'm trying to contact someone that represents Marvell here in Brazil, trying to get technical datasheet, but isn't easy...
Aug 05 16:41:13 <sn9> like i said before:
Aug 05 16:41:20 <sn9> but without the pins of the SoC visible, i don't know what help the datasheet would be
Aug 05 16:42:34 <sn9> i will be jtagging a marvell board myself within the next day or two
Aug 05 16:42:57 <sn9> datasheets? we don't need no stinkin' datasheets!
Aug 05 16:43:19 <juanpaul> so, that "datasheet" (if we can claim that a datasheet) isn't a technical datasheet, it's like a "promote datasheet"
Aug 05 16:43:28 <sn9> yes
Aug 05 16:44:39 <juanpaul> what device you have (and what are the marvell chipset)?
Aug 05 16:44:45 <sn9> the marvell device i will jtag is the AirLink101 AR625W
Aug 05 16:45:16 <sn9> i do not know exactly which marvell SoC it has because it's under a heatsink
Aug 05 16:45:24 <juanpaul> ok
Aug 05 16:45:37 <juanpaul> the most common is the 88w8510
Aug 05 16:46:18 <sn9> it reports itself as ARM926EJ-Sid
Aug 05 16:46:29 <juanpaul> if i remeber, i don't now any other device (except ew-7203apg) that uses 88w8515....
Aug 05 16:47:02 <juanpaul> it's reports that information, where?
Aug 05 16:47:30 <sn9> dmesg
Aug 05 16:47:50 <sn9> at least, before i accidentally overwrote u-boot, that is
Aug 05 16:48:03 <sn9> (over serial)
Aug 05 16:48:20 <sn9> it said: Machine: MV-88fxx81
Aug 05 16:48:33 <sn9> but that's the board
Aug 05 16:48:53 <juanpaul> humm... mine, over serial only reports eCos OS and some more thing that i don't remember now...
Aug 05 16:49:08 <p2-mate> it runs ecos ? funny
Aug 05 16:49:15 <juanpaul> yes
Aug 05 16:49:17 <sn9> eCos? interesting
Aug 05 16:49:25 <juanpaul> and yours?
Aug 05 16:49:29 <sn9> linux
Aug 05 16:49:57 <sn9> does asus have a source download for the eCos they used?
Aug 05 16:53:11 <juanpaul> appears that Asus WL-530G runs linux
Aug 05 16:54:34 <juanpaul> here some information: http://www.bitsum.com/openwiking/owbase/ow.asp?WL-530G#h24
Aug 05 16:55:29 <juanpaul> if you have looked at that datasheet we find, there's information about jtag (information that the device have a jtag port)
Aug 05 16:55:55 <sn9> that does not mean the board supports it
Aug 05 16:56:55 <juanpaul> not, but my board have 10 ~ 14 terminals left that appears to be the jtag port
Aug 05 16:58:30 <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...
Aug 05 16:59:13 <juanpaul> how i can find it (some voltage level or frequency) that i can find with my multimeter?
Aug 05 17:03:40 <sn9> you need to trace which contact goes to which pin on the SoC
Aug 05 17:04:10 <sn9> since the pins are not visible, you can't do that
Aug 05 17:05:02 <juanpaul> there's some alternative mode?
Aug 05 17:05:11 <sn9> i don't know
Aug 05 17:05:20 <p2-mate> you can use some trial and error
Aug 05 17:05:44 <juanpaul> some signaling that can be found with the osciloscope
Aug 05 17:05:51 <sn9> right
Aug 05 17:06:26 <juanpaul> okay, but what device i select to use with openjtag?
Aug 05 17:09:22 <juanpaul> what cpu
Aug 05 17:12:31 <sn9> use openocd
Aug 05 17:12:45 <sn9> not "openjtag"
Aug 05 17:13:07 <sn9> i have to leave now
Aug 05 17:16:07 <drath> the Marvell Feroceon is a modified ARM926EJ-S
Aug 05 17:16:46 <drath> the guys from #linkstationwiki have been able to flash their target, but debugging didn't work reliably
Aug 05 17:18:11 <p2-mate> drath: I have been told it's a marvell implementation of the armv5 arch ?
Aug 05 17:22:39 <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
Aug 05 17:25:29 <drath> i tried to get some information, but they wouldn't even let me sign an nda
Aug 05 17:25:46 <p2-mate> typical :P
Aug 05 19:41:56 <blogic> hi
