Nov 02 19:02:22 <lennert> i made the xilinx synthesizer segfault

Nov 02 19:02:27 <lennert> make: *** [destest.ngc] Segmentation fault
Nov 02 19:02:32 <lennert> i rock :P
Nov 02 19:02:34 <ka6sox-office> ha ha ha
Nov 02 19:03:22 <lennert> it's kind of easy, too
Nov 02 19:03:33 <lennert> just write     blah <= "1111";  outside a process
Nov 02 19:03:42 <lennert> and then inside a process, write  blah <= "0000";
Nov 02 19:04:54 <ka6sox-office> bad bad form :)
Nov 02 19:05:18 <ka6sox-office> looks like a Bozo No No to me.
Nov 02 19:05:22 <lennert> ka6sox-office: i deleted the assignment outside the process but didn't :wq before i resynthesized
Nov 02 19:06:21 <ka6sox-office> ah...that would do it.
Nov 02 19:06:31 <ka6sox-office> must eat now...back later
Nov 02 21:11:40 <key2> someone knows a device that could read fast a flash linked to a proc (MIPS) that has a JTAG/EJTAG interface ?
Nov 02 21:12:53 <ka6sox> key2, a couple of people are working on one the has USB interface :)
Nov 02 21:13:08 <ka6sox> but its not quite done :)
Nov 02 21:13:17 <ka6sox> very soon
Nov 02 21:13:18 <key2> like who ?
Nov 02 21:13:24 <ka6sox> ep1220
Nov 02 21:13:43 <key2> ka6sox: that's his nick ?
Nov 02 21:14:03 <ka6sox> ep1220
Nov 02 21:14:42 <ka6sox> I just received boards today and will be building them tommorrow.
Nov 02 21:14:51 <ka6sox> and then starting testing.
Nov 02 21:16:14 <ka6sox> you need MIPS and ejtag?
Nov 02 21:17:17 <key2> yeah
Nov 02 21:17:29 <key2> I made also a USB cable for ejtag
Nov 02 21:17:37 <key2> based on the ftdi2232
Nov 02 21:17:45 <key2> and a scenix microcontroller
Nov 02 21:17:52 <ka6sox> that is what this board is too..but no controller.
Nov 02 21:18:01 <key2> well that's slow then
Nov 02 21:18:04 <ka6sox> just the 2232.
Nov 02 21:18:14 <ka6sox> how fast are you looking for?
Nov 02 21:18:19 <key2> 2232 can perform read/write/readwrite
Nov 02 21:18:28 <key2> but not EJTAG_DMA_ control
Nov 02 21:18:31 <ka6sox> over 6mbits?
Nov 02 21:18:37 <key2> no
Nov 02 21:18:39 <ka6sox> okay I see what you mean
Nov 02 21:18:47 <key2> 1mb would be great
Nov 02 21:18:55 <key2> but his cable just uses the ftdi lib
Nov 02 21:19:09 <key2> so it's limited to the JTAG function and doesn't really now about ejtag
Nov 02 21:19:27 <ka6sox> that is where I think that we are going to have to rewrite the libftdi driver.
Nov 02 21:19:45 <ka6sox> (for better jtag control)
Nov 02 21:20:02 <key2> so it's basically slow since everytime he has to send on ReadWrite get the answer and send an other one so it's not worth using USB for that 
Nov 02 21:20:28 <key2> it's not really possible and even if it was, it would't help
Nov 02 21:20:43 <key2> since in ejtag, you have to wait untill some flags are set
Nov 02 21:20:49 <key2> so basically u have to read non stop
Nov 02 21:20:55 <ka6sox> k
Nov 02 21:20:57 <key2> untill you get the value you were looking for
Nov 02 21:21:10 <ka6sox> so you have to do a comparison then?
Nov 02 21:21:14 <key2> but everytime you do a READ, you send a usb frame of 4096 byte and only 32 of them are usefull
Nov 02 21:21:26 <key2> yeah
Nov 02 21:21:35 <key2> that's why I was using a Scenix microcontroller
Nov 02 21:22:04 <key2> http://www.parallax.com/detail.asp?product_id=SX48BD
Nov 02 21:22:10 <ka6sox> I was interested in using a Pic micro.
Nov 02 21:22:18 <key2> pic are too slow
Nov 02 21:22:32 <key2> look at the price of those one
Nov 02 21:23:11 <ka6sox> 20 MIPS is too slow?
Nov 02 21:23:26 <key2> yeah
Nov 02 21:23:33 <key2> 75Mips is already too slow
Nov 02 21:24:41 <key2> 6mb/s = 750kB/s
Nov 02 21:25:21 <key2> and it takes you much more than 100 8bit instructions to do a ejtag_dma_read
Nov 02 21:27:06 <ka6sox> hmmm...
Nov 02 21:27:41 <ka6sox> I thought that ejtag allowed you to set the flags and then just read what you wanted.
Nov 02 21:28:05 <ka6sox> instead of having to read the stream and wait until what you wanted to come back.
Nov 02 21:28:23 <ka6sox> brb...putting child to bed.
Nov 02 21:30:55 <key2> no
Nov 02 21:31:05 <key2> everytime you wanna do a ejta_dma_read
Nov 02 21:32:22 <key2> you have to do few ReadWrite()
Nov 02 21:32:32 <key2> then get the EJTAG registers back
Nov 02 21:32:46 <key2> it takes a while
Nov 02 21:32:47 <key2> believe
Nov 02 21:32:51 <key2> believe me
Nov 02 21:42:02 <ka6sox> I do
Nov 02 21:43:16 <ka6sox> sounds like what you need is an Abatron
Nov 02 21:54:55 <key2> I need a very very cheap 32bit microcontroller
Nov 02 21:55:34 <ka6sox> ya...but bitbanging 6mb/sec isn't fun.
Nov 02 21:56:39 <key2> yeah
Nov 02 21:56:41 <key2> right now
Nov 02 21:56:49 <key2> it takes me 12s to read 64Kb of memory
Nov 02 21:57:24 <key2> which means 12min to read the whole memory
Nov 02 21:57:28 <key2> tooo slow
Nov 02 21:57:45 <ka6sox> takes us 40 minutes to write 256kB of bootloader with the IXP420
Nov 02 21:58:13 <ka6sox> (with a wiggler) this tool should get it down to about 6 minutes.
Nov 02 21:58:53 <key2> wigller ?
Nov 02 21:59:03 <key2> what tool shout do it in 6min ?
Nov 02 22:00:05 <key2> i'm scared ending up to do it with a fpga
Nov 02 22:00:27 <ka6sox> thats what I'm playing with...a Spartan3 board.
Nov 02 22:00:37 <ka6sox> it can easily do 6mb/sec
Nov 02 22:00:39 <ka6sox> and do the comp too.
Nov 02 22:00:42 <key2> vhdl or verilog ?
Nov 02 22:00:45 <ka6sox> vhdl
Nov 02 22:00:50 <ka6sox> (xilinx)
Nov 02 22:00:50 <key2> fuck
Nov 02 22:00:53 <key2> prefer verilog
Nov 02 22:00:55 <key2> yeah
Nov 02 22:00:59 <key2> I have one of those board
Nov 02 22:01:05 <key2> Digilent one
Nov 02 22:01:12 <key2> with spartan3
Nov 02 22:01:13 <ka6sox> thats the one.
Nov 02 22:01:18 <ka6sox> and 1MB of memory
Nov 02 22:01:18 <key2> 100 bucks
Nov 02 22:01:31 <key2> what do you do in life ?
Nov 02 22:01:53 <ka6sox> Broadcast engineer/Hardware developer
Nov 02 22:02:03 <ka6sox> (and play with VHDL stuffs)
Nov 02 22:02:21 <key2> ok
Nov 02 22:02:29 <key2> normally if I take a small fpga
Nov 02 22:02:29 <ka6sox> you?
Nov 02 22:02:39 <key2> let's say xc2s familly
Nov 02 22:02:49 <key2> can I make it ?
Nov 02 22:03:53 <ka6sox> what TZ are you in?
Nov 02 22:03:59 <key2> TZ ?
Nov 02 22:04:09 <ka6sox> Timezone.
Nov 02 22:04:13 <key2> oh
Nov 02 22:04:15 <key2> paris/fr
Nov 02 22:04:18 <key2> it's 6 am
Nov 02 22:04:22 <ka6sox> morning.
Nov 02 22:04:27 <key2> AM
Nov 02 22:04:27 <key2> :)
Nov 02 22:04:28 <key2> yeah
Nov 02 22:04:30 <ka6sox> its 9pm here.
Nov 02 22:04:34 <key2> need to sleep
Nov 02 22:04:37 <ka6sox> UTC-8
Nov 02 22:04:39 <key2> u're in california ?
Nov 02 22:04:43 <ka6sox> ya
Nov 02 22:04:46 <key2> wherea bout
Nov 02 22:04:51 <ka6sox> Santa Barbara
Nov 02 22:04:56 <key2> oh :)
Nov 02 22:05:01 <key2> i used to live in LA
Nov 02 22:05:01 <ka6sox> expensive.
Nov 02 22:05:11 <ka6sox> where? I grew up in OC.
Nov 02 22:05:26 <key2> west hollywood
Nov 02 22:05:44 <ka6sox> ah...what took you to paree?
Nov 02 22:05:57 <key2> paree ?
Nov 02 22:06:11 <ka6sox> paris
Nov 02 22:06:19 <key2> i'm french
Nov 02 22:06:25 <key2> the question should be what took me to la :)
Nov 02 22:06:25 <ka6sox> good reason.
Nov 02 22:06:34 <ka6sox> okay what took you here?
Nov 02 22:06:41 <key2> a chickj
Nov 02 22:06:43 <key2> -j
Nov 02 22:07:01 <key2> a girl I met here few years ago
Nov 02 22:07:15 <ka6sox> ah...did you bring her back?
Nov 02 22:07:24 <key2> fuck no :)
Nov 02 22:07:39 <ka6sox> ah...
Nov 02 22:07:51 <ka6sox> I'm here most of the time...
Nov 02 22:07:56 <key2> I had no money there so I was workin in bars, and then I used to fuck around so much with other girls that my relation with her had no sence
Nov 02 22:08:11 <key2> so after I realized that I'm wasting my time there, I came back
Nov 02 22:08:27 <ka6sox> what are you doing now?
Nov 02 22:08:42 <key2> engineering..
Nov 02 22:08:45 <key2> in a DSL company
Nov 02 22:08:53 <ka6sox> fun.
Nov 02 22:08:57 <key2> yeah
Nov 02 22:09:08 <ka6sox> there is a good group here...
Nov 02 22:09:11 <key2> that's what I originally studdied, not bartending :)
Nov 02 22:09:36 <key2> so basically
Nov 02 22:09:45 <key2> I need to make a cable that would be very chip and very fast
Nov 02 22:10:09 <ka6sox> sounds like a S3 or Virtex2 type would do it.
Nov 02 22:10:10 <key2> so since a pic and a scenix won't make it (not fast enough)
Nov 02 22:10:25 <key2> well S3 are first BGA (for most of them)
Nov 02 22:10:35 <key2> then I don't need that amount of gate for just driving a jtag
Nov 02 22:10:42 <key2> so I'm planning on something smaller
Nov 02 22:10:43 <key2> and cheaper
Nov 02 22:10:47 <ka6sox> CPLD?
Nov 02 22:10:54 <key2> no
Nov 02 22:10:56 <key2> small fpga
Nov 02 22:10:59 <key2> like I said
Nov 02 22:11:15 <ka6sox> what are you going to feed it with?
Nov 02 22:11:24 <key2> cx2s15 or xc2s30 should make it
Nov 02 22:12:01 <key2> well from one side, I have to take the data, and the type of instruction
Nov 02 22:12:10 <key2> and from the other, I have to read/write on the jtag
Nov 02 22:12:12 <ka6sox> sounds like you dont' need a lot of pins.
Nov 02 22:12:23 <key2> not at all
Nov 02 22:12:53 <ka6sox> I like the Coolrunner II's that I"m now playing with.
Nov 02 22:12:56 <key2> but don't know if I should use a uC with it or if it would be a waste
Nov 02 22:13:08 <key2> how many logical gate?
Nov 02 22:13:19 <ka6sox> something like 15K
Nov 02 22:14:06 <key2> I think it's fine
Nov 02 22:14:20 <key2> but don't really know how to implement it
Nov 02 22:15:58 <ka6sox> 323MHz parts.
Nov 02 22:20:18 <ka6sox> gotta run now...be back on later...I'm here a lot..unless I"m not :)
Nov 02 23:48:09 <ka6sox> morning ep1220 boards arrived.
Nov 02 23:54:13 <ep1220> ka6sox: hello, hope all went well with Your son's surgery
Nov 02 23:54:29 <ka6sox> ep1220, yes..hes finally feeling better.
Nov 02 23:54:37 <ka6sox> almost a week later :)
Nov 02 23:55:01 <ep1220> good to hear.
Nov 02 23:55:05 <ka6sox> yes.
Nov 03 02:20:12 <lennert> ka6sox: you have any vhdl to share yet?
Nov 03 02:21:32 <ka6sox> I should have it up by weeks end.
Nov 03 02:21:48 <ka6sox> right now I've got to get a presentation going.
Nov 03 02:34:10 <lennert> okay
