| 05:34 | jnettlet | vpeter, is this the same sfp module you posted the data sheet on the other day? |
| 05:37 | jnettlet | if your sfp module can work in fast mode then I would recommend we change the device tree to run the i2c1 device at 400kHz. You can't do that by default because it breaks the SFP spec, however the Marvell i2c controller has errata regarding issues running at 100kHz. |
| 08:40 | vpeter | jnettlet: yes, it is model XSUEG1-M1RN-GC http://sup.xenopt.com/pluggables/XSUEx1-M1Rx.pdf |
| 08:42 | vpeter | this pdf has mine covered http://www.xenya.si/wp-content/uploads/2014/05/XSUEx1-M1Rx.pdf |
| 08:43 | vpeter | From what I see it is only 1000Mbps. |
| 09:01 | jnettlet | okay so that uses this i2c eeprom. http://de.rs-online.com/webdocs/0028/0900766b80028ad9.pdf |
| 09:01 | jnettlet | and it specifies that it is fast mode compliant. |
| 09:04 | vpeter | Ah, this fast mode. |
| 09:04 | jnettlet | so try applying this patch and rebuilding the dtbs. https://pastebin.com/g3w71XGv |
| 09:29 | vpeter | I have clearfog pro - will adjust the patch. |
| 09:30 | jnettlet | vpeter, you don't need to adjust it. That patch adds the clearfog base, but then splits shared devices into a dtsi file |
| 09:31 | vpeter | Ah, then I missed this part. |
| 10:17 | vpeter | Nope, armada-388-clearfog-pro.dtb still has 100kHz like I though. Need adjustments. |
| 10:19 | vpeter | There are 3 different clearfog dtb's. |
| 11:01 | vpeter | Good, now dtb looks ok. Will test in 8 hours. |
| 11:01 | vpeter | But I'm wondering: why would higher frequency help? I would assume lower one would. |
| 12:36 | jnettlet | vpeter, the Marvell soc has an errata regarding the i2c controller |
| 13:09 | vpeter | Seems no one is capable of doing stable i2c. And it is such a simple protocol. Even small PIC microcontroller has errata for it :( |
| 13:45 | jnettlet | well hardware bugs do happen. Did the device-tree change fix it? |
| 13:50 | vpeter | Not tested yet - clearfog is at home and I'm at work. |
| 17:44 | Ke | heh s-r bumped MBin delivery time to 8 weeks |
| 17:44 | Ke | still no registered dimm support =o) |
| 17:59 | vpeter | jnettlet: sadly no change :( :( |

| 18:46 | vpeter | "I/O error" if I see correctly. |
| 18:47 | vpeter | Any more ideas? |
| 20:19 | jnettlet | I am thinking about it |
| 20:23 | vpeter | I'm rebuilding whole lede just in case. |
| 21:39 | vpeter | Fresh build didn't changed anything. Even i2cdetect doesn't find device anymore. |
| 22:21 | vpeter | jnettlet: this seems ok? :) |

| 22:21 | vpeter | I changed clock-frequency to 50kHz and got this. |
| 22:22 | vpeter | Now let's figure out how to use this adapter. |
| 23:11 | topi` | I wonder if CloudFog base/pro is available for purchase from any retailer inside EU? to avoid vat/customs |
| 23:11 | topi` | especially the customs is nasty, since most companies seem to ask for a fixed 25 EUR fee for their "services" |
| 23:12 | topi` | I had to pay a 95 eur bill for the handling of vat/customs of my macchiatoBin order |
| 23:12 | topi` | this on top of the $300 for the device itself plus some $25 shipping |
| 23:14 | topi` | I mean ClearFog, not CloudFog ;) |
| 23:15 | topi` | amazon.de has a page, but it says it is not available |
