| 00:00.04 | rwhitby | look for pullups on the RX signals |
| 00:00.17 | rwhitby | do you have a picture of the underside of that area? |
| 00:00.48 | [g2] | nod. |
| 00:01.03 | [g2] | I can post to the gallery |
| 00:01.25 | rwhitby | pin 2 is probably connected to the + terminal of CA13 (the big empty circle) - another indication of VCC |
| 00:02.24 | rwhitby | if you have a digital pulse tester, you can look for activity on the TX pins during boot (console messages) |
| 00:02.47 | rwhitby | can't see any pullups - maybe the ixp has them internal |
| 00:03.14 | beewoolie | [g2]: Dude. That rocks. |
| 00:04.55 | [g2] | you guys rock! |
| 00:06.37 | rwhitby | [g2]: registered rv042-linux.org yet? |
| 00:06.51 | beewoolie | ...here we go... |
| 00:06.59 | [g2] | I've got alot bigger plans :) |
| 00:07.58 | [g2] | Ok there's a 3rd pic from the bottom there |
| 00:10.30 | [g2] | there are no traces on the bottom |
| 00:10.35 | [g2] | only on the top |
| 00:10.51 | jacques | multi-layer? |
| 00:11.07 | beewoolie | [g2]: It looks like the bottom row is all ground. |
| 00:11.47 | rwhitby | [g2]: pin2 may still be vcc connected on an internal plane |
| 00:11.54 | rwhitby | or maybe there is no power on that header |
| 00:12.13 | beewoolie | Same on the other side. All odd pins are ground. |
| 00:12.30 | rwhitby | beewoolie: didn't I just say that before? :-) |
| 00:12.41 | beewoolie | I didn't read everything. Sorry. |
| 00:12.45 | rwhitby | np |
| 00:12.57 | rwhitby | the more heads the better :-) |
| 00:13.23 | [g2] | amen to that and you guys are good heads ! :) |
| 00:13.34 | beewoolie | It is interesting that there are, seemingly, four signal pins. |
| 00:15.34 | rwhitby | Pinky: "What are we going to do tonight, [g2]?" [g2]: "Same thing we do every night Pinky, try to take over the world!" |
| 00:15.38 | beewoolie | rwhitby: Isn't the bit empty circle really BT1? |
| 00:16.12 | rwhitby | indeed yes |
| 00:16.35 | rwhitby | beewoolie: two UARTS |
| 00:16.43 | rwhitby | or maybe RTS and CTS if you are very lucky |
| 00:16.49 | beewoolie | The fact that the + pad for the battery has no attachments is further indication that they are using a power plane. |
| 00:16.57 | beewoolie | rwhitby: Hmm. Interesting. |
| 00:17.15 | beewoolie | That could be handy. |
| 00:17.26 | rwhitby | hardware flow control - high speed serial |
| 00:18.56 | beewoolie | I'd really doubt that they'd put in rts/cts, but it is possible. Usually, these lines also require DTR and DSR. |
| 00:20.29 | [g2] | hey I'm just trying to make a little sw work |
| 00:21.24 | [g2] | I'd guess that the 4 signal pins are COM1 and COM2 |
| 00:22.57 | [g2] | OK, I can dig up the volt meter and verify 3.3 and GND |
| 00:23.56 | [g2] | then I can probe for the TX from the IXP to the level-shifter |
| 00:24.07 | [g2] | then find the RX and we should be all set |
| 00:24.25 | [g2] | I'll be back later |
| 00:24.33 | rwhitby | ok |
| 00:24.41 | [g2] | THX for all the help! |

| 22:41.24 | beewoolie-akf | yo |
| 22:41.42 | [g2] | how goes my pal ? |
| 22:41.56 | beewoolie | I've got opie running. Make me really rilly happy. |
| 22:42.34 | [g2] | cool.... so oe built ? |
| 22:42.37 | beewoolie | There are a few issues to resolve, the screen blanks and doesn't restore, and other little things. |
| 22:42.40 | beewoolie | God no. |
| 22:42.49 | beewoolie | I gave up on OE a long time ago. |
| 22:42.57 | beewoolie | I'm using Make scripts for the time being. |
| 22:43.17 | beewoolie | I've also built most of gpe, but I got tired of resolving dependencies. |
| 22:43.21 | [g2] | you've got that make sniffer right ? |
| 22:43.32 | beewoolie | Moreover, it is meant for larger systems than what I've got. |
| 22:43.34 | beewoolie | Make sniffer? |
| 22:43.53 | [g2] | the make that recorded all the file accesses ? |
| 22:44.11 | beewoolie | Uh, no. I'm not sure what that would be. |
| 22:45.09 | [g2] | so you'll be all ready to play with OpenJTAG and the RV soon eh ? :) |
| 22:46.38 | beewoolie | Soon. I've got the cleanup at this point. I need to be able to build an image of reasonable size so that the SEs can demo the platform. |
| 22:46.49 | beewoolie | Should be about a week, I think. |
| 22:52.50 | beewoolie | [g2]: How is the 042? Any line on serial? |
| 23:27.49 | [g2] | beewoolie, sorry I was on the other computer ! :( |
| 23:28.28 | [g2] | the RV 042 and 082 are quite interesting |
| 23:29.02 | [g2] | My soldering has improved alot and don't hose things up, however it doesn't get serial access yet |
| 23:29.08 | beewoolie | What's your goal. |
| 23:29.35 | [g2] | well I wanted to get to the bootloader and shell |
| 23:29.51 | [g2] | and a funny thing happened on trying to get serial working :) |
| 23:31.39 | [g2] | beewoolie, in searching for the proper pin connections, I ran across the two backdoors on the the box |
| 23:31.59 | [g2] | 1) straight to the bootloader from the network |
| 23:32.22 | [g2] | 2) to an application via telnet from the network and then to a shell |
| 23:32.42 | [g2] | so the boxes are really pretty open |
| 23:33.02 | [g2] | I had switchbox 4.11 running from the shell |
| 23:33.09 | [g2] | I chrooted onto / |
| 23:33.13 | [g2] | via the switchbox |
| 23:35.18 | [g2] | So the 082 runs a 533 which is quite zippy |
| 23:35.45 | [g2] | the 042 @ 266 is quite zippy compared to the slug, but similar to the Avila board |
| 23:36.00 | beewoolie | Interesting. |
| 23:36.06 | beewoolie | What kernel are they running? |
| 23:36.23 | [g2] | they are running 2.4.19-rmk1-openrg |
| 23:36.27 | [g2] | iirc |
| 23:38.36 | [g2] | Linux version 2.4.19openrg-rmk6-ds1 (root@localhost.localdomain) (gcc version 2.95.3 20010315 (release/MontaVista)) #2 Wed Nov 3 16:32:07 CST 2004 |
| 23:38.54 | [g2] | ok... I was kinda close :) |
| 23:38.57 | beewoolie | Interesting. |
| 23:39.17 | beewoolie | Is the bootloader redboot? |
| 23:39.27 | [g2] | I don't think so |
| 23:39.42 | [g2] | but maybe |
| 23:40.53 | [g2] | I think they are booting directly to an ecos application |
| 23:41.06 | [g2] | or maybe just an application |
| 23:41.36 | beewoolie | Hmm. So they boot ecos and then linux. |
| 23:41.54 | [g2] | I read something about that in my search for the proper pin setup.. Some smart guy noticed the same messages twice while booting |
| 23:42.57 | [g2] | So.... my next trick is to reload the kernel live from memory :) |
| 23:43.44 | [g2] | either that or get the serial port working and get APEX on there |
| 23:44.15 | beewoolie | Well, APEX should work. |
| 23:44.41 | [g2] | well it an ixp425 so it might need to be tweaked a little |
| 23:45.16 | [g2] | also I'll need serial or JTAG as a fall back in case something doesn't work properly |
| 23:49.33 | beewoolie | Hmm. Shouldn't be necessary. There are only real differences in the extra cores. |
| 23:50.24 | [g2] | maybe.. Well probably find out real soon |
| 23:50.57 | [g2] | I feel like I'm quite close on the serial |
| 23:51.05 | beewoolie | koo |
| 23:53.26 | [g2] | I'll probably download a full root fs and run programs from there for a while, there are some options for reflashing from the bootloader |
| 23:53.46 | [g2] | however, I think you can nuke yourself from either the bootloader or the running image |
| 23:57.10 | beewoolie | It would be ideal if you could load a new image into memory while it is running. |
| 23:58.44 | beewoolie | it would also be an interesting data point to see if APEX runs on this device. |
| 23:58.50 | beewoolie | Although, there is no USB. |
