 emily | than what I want | 15:37:58 |
 K900 | Honestly you should probably just do that | 16:23:45 |
| K900 | Anything but MII over SFP was a mistake | 16:23:51 |
| K900 | I will die on this hill | 16:24:00 |
| emily | well, at that point I'm relying on the SFP to get things like jumbo frames right, yeah? | 16:26:34 |
| emily | I messaged SinoVoip on AliExpress and their automatic response started "Dear friends, welcome to our Facebook group". ok | 16:26:53 |
| K900 | Not really | 16:29:29 |
| emily | the 1000BASE-T transceiver I'm using right now can't handle them at least | 16:30:02 |
| K900 | OK so I am still not sure WHY | 17:43:30 |
| K900 | But I'm pretty sure the MAC is not getting to the right mode for 2500base-x operation with this thing | 17:44:06 |
| K900 | But the phylink mode setup code is absolutely ridiculous | 17:44:44 |
| K900 | And it's basically impossible to debug it when the phy on the other end gives up on you after like 15 seconds | 17:46:16 |
| K900 | And also runs my primary home network | 17:46:23 |
| K900 | So I'll just live the 1000base-x life for now | 17:46:33 |
| emily | what advantage would 2500 give you? slightly more throughput from less overhead on the link or something? | 17:52:54 |
| K900 | Yeah and in theory they can do up to 2gbps link rates on the ISP end | 17:53:54 |
| K900 | Though it is priced at "call us for a quote" | 17:54:07 |
| K900 | They technically offer up to 10G in some areas but the way to check availability is, you guessed it, call them for a quote | 17:56:15 |
| K900 | But 2G down is technically within spec for vanilla GPON | 17:56:46 |
| K900 | Which means they technically don't need XGSPON equipment | 17:56:59 |
| emily | right. the 1800/120 service I'm hoping to get soon is GPON | 18:00:31 |
| emily | shame about the 120. | 18:00:41 |
| K900 | I'm getting what's supposed to be 1gbps symmetric | 18:18:22 |
| K900 | (it's not, because pon lol) | 18:18:28 |
| emily | the overprovisioning here is significant enough that I seem to reliably get what i'm meant to | 18:19:25 |
| emily | K900: the BPI-R4 can't see the SD when booting from NAND, right? so I guess you have to use either eMMC or an M.2 to boot if you flash a U-Boot to NAND? | 18:39:54 |
| K900 | I don't think that's a thing? | 18:40:16 |
| emily | what do you mean? | 18:40:46 |
| emily | it's documented pretty much everywhere that it can't see SD and eMMC at the same time. hence the two DTs | 18:40:59 |
| K900 | It shouldn't have anything to do with booting from NAND | 18:41:01 |
