| aeris | adam a reçu le bidule ? | 04:34 |
| lekernel | ah, je ne sais pas, je demande | 04:41 |
| lekernel | tu vas au fosdem au fait? | 04:41 |
| aeris | Ui | 04:41 |
| roh | hackabledevices down? | 04:47 |
| wolfspraul | lekernel: nice, congrats for the article! | 05:00 |
| wolfspraul | ha, Anika Kehrer again - she's cool! | 05:01 |
| roh | hm. found a bug. it was 27c3 not 26c3 ;) | 05:58 |
| lekernel | no, i did present it at 26c3 | 05:59 |
| kristianpaul | and booted linux at that time ;-) | 06:00 |
| rejon | lekernel where you staying at for fosdem? | 06:00 |
| lekernel | at a hotel | 06:01 |
| rejon | which? | 06:02 |
| rejon | looking for pointers | 06:02 |
| rejon | b4 i get ripped off | 06:02 |
| roh | lekernel: ah.. ok. so you have 2 congresses on it now ;) | 06:07 |
| roh | good things need time | 06:08 |
| lekernel | well, only 26c3 was successful. they really fucked up the workshops at 27 | 06:08 |
| lekernel | rejon: hotel bloom, rue royale | 06:13 |
| wolfspraul | lekernel: btw Adam is working on the power-up bug | 06:21 |
| wolfspraul | he went to xilinx last week and spent 2.5h there, discussing the thing. he has some new ideas he is trying now (just in case you don't already know all this) | 06:21 |
| lekernel | he found it, didn't he? | 06:22 |
| lekernel | from my understanding, it's a race condition between fpga and flash startup, and for some reason (Adam didn't tell me why) the capacitor I had planned to solve this potential problem didn't work as expected | 06:23 |
| rejon | lekernel cool | 06:27 |
| wolfspraul | lekernel: I don't know, I am waiting. | 06:28 |
| wolfspraul | I hate to cause stress on people. | 06:29 |
| wolfspraul | let him do his proper work until he is happy :-) | 06:29 |
| wolfspraul | if he found it - great! | 06:29 |

| mwalle | hi | 15:48 |
| kristianpaul | hola | 16:02 |
| mumptai | hi | 16:40 |
| mumptai | the fpga is the only device on the jtag chain on the mm1? | 17:00 |
| mwalle | mumptai: yes | 17:00 |
| kristianpaul | yes | 17:00 |
| mumptai | okay, then i got to read more, thx | 17:01 |
| mumptai | did the urjtag systax hange lately? | 17:10 |
| mumptai | i'm getting a syntax error with that fjmem batch | 17:11 |
| mwalle | i dont think so | 17:11 |
| mwalle | what error | 17:11 |
| mwalle | ? | 17:11 |
| mumptai | this one: "Error: part.c:355 urj_part_instruction_define() invalid parameter: invalid instruction length" | 17:11 |
| mumptai | which is the response to: "instruction CFG_OUT 000100 BYPASS" | 17:13 |
| mwalle | did the detect return successfully? | 17:13 |
| mumptai | it detects the prom an the spartan | 17:14 |
| mwalle | PROM? | 17:14 |
| mwalle | what board | 17:14 |
| mumptai | and i select the later one with "part 1" | 17:14 |
| mumptai | nexys2 | 17:15 |
| mwalle | unfortunately, i dont have a working urjtag right now, but i tried it with my spartan 3e eval board | 17:20 |
| mwalle | are you sure you've chosen the right part? | 17:20 |
| mwalle | there is a command which should display the instruction length | 17:21 |
| mumptai | detect does | 17:22 |
| mumptai | IR length is 14 | 17:22 |
| mwalle | the complete chain? | 17:26 |
| mumptai | yes | 17:28 |
| mwalle | try print | 17:29 |
| mumptai | it says "non" multiple times | 17:30 |
| mumptai | s/non/none/ | 17:30 |
| mwalle | where? | 17:30 |
| mwalle | could you paste it somewhre | 17:31 |
| kristianpaul | mumptai: did you : instruction CFG_OUT 000100 BYPASS | 17:31 |
| kristianpaul | instruction CFG_IN 000101 BYPASS | 17:31 |
| kristianpaul | before pld load right? | 17:31 |
| mumptai | there is one row | 17:31 |
| mumptai | labled as No. 1 | 17:31 |
| mumptai | no mfg., no part | 17:32 |
| mumptai | and Stepping instr. and register are "(none)" | 17:32 |
| mumptai | kristianpaul, yes | 17:33 |
| mwalle | and detect detect, detects a xilinx device? | 17:33 |
| mumptai | and says that is can't find info about the stepping | 17:34 |
| kristianpaul | paste i tsomwhere | 17:34 |
| mumptai | but it decodes the IDs correctly | 17:34 |
| mwalle | ah ok, so you have to add the stepping in data/xilinx/<part>/STEPPINGS | 17:35 |
| mwalle | did it ever work? | 17:35 |
| mumptai | yes | 17:36 |
| mumptai | wait | 17:36 |
| mumptai | but that wasn't in the interactive mode | 17:36 |
| mwalle | with exactly that fpga? | 17:38 |
| kristianpaul | mumptai: what jtag cable are you using btw? | 17:38 |
| mumptai | aww | 17:39 |
| mwalle | i guess you are using the onboard 'cable' of the nexys2? | 17:41 |
| mumptai | works better with proper scan files ;) | 17:41 |
| mwalle | but why have it worked before? | 17:42 |
| kristianpaul | mumptai: [OT] are you aware if there is support for Bus pirate from urjtag project? | 17:42 |
| mumptai | kristianpaul, no wasn't. but i can actually load a bit-file into the fpga using urjtag, so it can't be that broken ;) | 17:43 |
| kristianpaul | :) | 17:43 |
| mwalle | kristianpaul: have you tried the bus pirate with urjtag? | 17:44 |
| mwalle | last time i tried it was very slow | 17:44 |
| mumptai | now i get this: http://codepad.org/pdO57784 | 17:45 |
| kristianpaul | mwalle: but, but i willing to do so with my avnet board | 17:45 |
| kristianpaul | s/but/no | 17:45 |
| kristianpaul | try frequency 12000000 ?? | 17:46 |
| mumptai | the tck rate is actually hard-coded into the cable's controller code | 17:48 |
| kristianpaul | hmm | 17:48 |
| mumptai | its a cypress fx2 running some altera usb-blaster emulation | 17:50 |
| mumptai | maybe i messed up the ucf, or the flash isn't yet supported | 17:52 |
| mumptai | will double check that when i find another spare evening | 17:53 |
| mwalle | mumptai: i guess your are too fast for the flash detection | 17:54 |
| mumptai | mhmmm | 17:54 |
| mwalle | you get the same error with the FT2232H if you dont set the frequency to 6MHz | 17:54 |
| mumptai | its not really running at 12MHz, probably not even above 2MHz | 17:55 |
| kristianpaul | did flash memory mind about it? it seems.. | 17:55 |
| mumptai | that is a 8051 core doing some bit-banging ... | 17:55 |
| kristianpaul | is not that worst? :) (bit bang?.. above 2Mhz..) | 17:56 |
| kristianpaul | mumptai: can you confirm with flash memory data sheet? | 17:56 |
| mumptai | i can, but i got to get up in less than 7 hours | 17:57 |
| mumptai | so, good night | 17:59 |
| mumptai | and thanks for you help | 17:59 |
| kristianpaul | sure | 18:00 |
| kristianpaul | hey 7 hrs still un fair ! | 18:00 |
| kristianpaul | sleep from 5 to 6 hrs a day is posible :-) | 18:01 |
| mwalle | im going to bed too | 18:01 |
| mwalle | gn8 :) | 18:01 |
