| 16:29.40 | keesj | yo |
| 16:38.34 | dirk2 | keesj: If I remember correctly, you used Saleae for OMAP3 JTAG debugging? |
| 16:39.10 | dirk2 | keesj: There is now some discussion at beagle ml that Saleae doesn't Support 1.8V. Any idea? |
| 16:41.30 | dirk2 | keesj: http://groups.google.com/group/beagleboard/msg/a3f44b7ce5be9b33 |
| 16:47.31 | keesj | dirk2: yes I saw that disc, it was monitoring the jtag signals indeed, |
| 16:49.21 | keesj | zeroplus looks good |
| 16:49.52 | dirk2 | for zeroplus there are a lot of devices, and I can't find the prices. They link to resellers |
| 16:50.22 | dirk2 | the jtag signals: At 1.8V level or behind any level shifters? |
| 16:52.16 | dirk2 | btw: Are you on the Saleae Linux notification list? Any news regarding Saleae and Linux support? |
| 16:56.18 | keesj | dirk2: but the thread initialy was not about logic analyzer if you ask me |
| 16:57.10 | keesj | I started reverse engineering the protocol but I don't have a vista machine any more (still have the traces) |
| 16:57.32 | keesj | let met ask them again. last time they said "comming" bug that is way to long ago |
| 16:59.38 | dirk2 | keesj: Sorry, I just wanted to know if you can remember if you used Saleae with 1.8V JTAG signals (i.e. proving that statement at mailing list is wrong) or if you measured at some other voltage levels? |
| 17:02.59 | keesj | the specs here http://www.saleae.com/logic/specs/# say it should not work but this cleary is not true |
| 17:05.24 | keesj | dirk2: the openocd discs just makes me even like openocd less |
| 17:23.19 | dirk2 | keesj: yes, I looked at the code and it is not easy to understand. But Magnus does really help! |
| 17:24.42 | dirk2 | keesj: and, while I haven't read all of Zach's discussion, it seems he has an idea what to improve |

| 19:16.58 | ja2 | Hi, I request some help. I probably have ytouble installing drivers for ft2232 on ubuntu, since openocd tell me " No valid jtag interface found (ft2232)". Can anyone put some light on this problem? |
| 19:17.28 | ja2 | Im using a USB-TINY jtag from Olimex. |
| 19:19.43 | dirk2 | try as root |
| 19:22.14 | ja2 | As root didnt help. |
| 19:22.29 | ja2 | I dont have /proc/usb/devices, since my system uses udev. |
| 19:22.34 | ja2 | Is that a problem? |
| 19:29.09 | ja2 | Ah, I found a way to see the usb devices, and I see that " Driver=(none)" for the Jtag Tiny. |
| 19:29.51 | ja2 | Now I need a way to tell what driver it should use... |
| 20:38.22 | keesj | o you need to mount the usbfs .... |
| 20:38.29 | keesj | that is that libusb is using |
| 20:53.42 | ja2 | Hmm, I did, still no good result. |
| 20:54.26 | ja2 | keesj: Mount point is /proc/bus/usb/, right? |
| 21:46.56 | ja2 | I b back 2morrow |

| 23:49.12 | Circuitsoft | Hello. |
| 23:49.46 | Circuitsoft | Question: Running the Segger Jlink "Beta Software for Linux" while connected to my target hardware tells me I have two devices with a total IRLen of 16. |
| 23:50.02 | Circuitsoft | Does that mean that the sum of the IRs of the two devices is 16? |
| 23:50.56 | roxfan | sounds like it |
| 23:52.17 | Circuitsoft | It also told me the IDs of the two devices. Any idea where I could look them up to determine the proper jtag_device lines for them? |
| 23:52.37 | Circuitsoft | I know the part number of the chip, but I can't find datasheets for it anywhere. |
| 23:53.12 | Circuitsoft | One device is an arm946ij-s, the other is a DSP that I don't care to touch. |
