02:37 <Daanct12> greets

02:38 <Daanct12> i'm testing out the vop2 patches for u-boot one more time and i'm going to send it out

09:29 <jmabsd> Hi all, what is the cheapest ARM64 and RISCV64 board with an M.2 PCI connector, ability to hook it to Power over Ethernet, and maybe 4GB or 2GB RAM?

09:30 <jmabsd> what are good channels to ask this question

09:31 <jmabsd> About the Power over Ethernet part, I think a separate module can solve it. It will feed USB PD. So just a ARM64/RISCV64 board with an M.2 22x80mm PCI connector and 4GB or 2GB RAM.

09:36 <jmabsd> low watt consumption when idling if possible.

10:04 <jmabsd> the way, if you skip the PCI requiremenet and only demand two USB3 connections and 4GB or 2GB RAM, what's the cheapest SBC then?

14:46 <Daanct12> i've submitted v3 of vop2 u-boot: https://lore.kernel.org/u-boot/20250412-vop2-pt2-v3-0-7c796db335e9@riseup.net/

18:03 <jmabsd> Hi all, which RK3588 SBC:s exist with 2.5gbit Power over Ethernet built in already?  I'm aware of Rock5B+

18:03 <jmabsd> Any more?

18:09 <jmabsd> The RK3588 actually has dual 2.5gbit ethernet phy:s from the SoC, so the two 2.5gbit ethernet connectors on "NanoPC-T6" will have good speed and not be routed via USB right? https://www.friendlyelec.com/index.php?route=product/product&product_id=292

18:11 <CounterPillow> The RK3588 does not have 2.5Gbit/s NICs. On the Rock5B, it uses a PCie Realtek NIC for that

18:13 <jmabsd> CounterPillow: Oh. Hm. What chip is used on the NanoPC-T6?

18:13 <jmabsd> Will google it. I like to understand performance.

18:14 <jmabsd> The "NanoPC-T6" has one 4-lane PCIe v3 M.2 22x80mm slot, and then two smaller slots that are single lane PCI I think.

18:14 <CounterPillow> the smaller slots are 1 lane of PCIe 2.1

18:14 <CounterPillow> they're from the combo phys

18:14 <zeha> wiki says rtl8125bg

18:15 <jmabsd> https://wiki.friendlyelec.com/wiki/index.php/NanoPC-T6 says "Ethernet: 2 x PCIe 2.5G Ethernet"

18:15 <jmabsd> zeha: oh nice. URL?

18:16 <jmabsd> I also wonder if the NanonPC-T6 can be powered via USB PD

18:16 <CounterPillow> Everything will basically be those realtek PCIe NICs, they work fine.

18:17 <jmabsd> Looks like via barrel only, "About Power    Power supply via 5.5*2.1mm DC Jack. 5V~20V, 12V is recommended."

18:17 <jmabsd> CounterPillow: For sure better than Intel I225, which is a broken chip.

18:17 <zeha> just scroll down on that page

18:19 <jmabsd> Ah right it says "Optimized r8125 performance and stability".

18:23 <jakllsch> what's wrong with i225/i226?

18:39 <jmabsd> Ah here is how the Radxa POE HAT looks on the Rock5B(+), great: https://www.youtube.com/watch?v=IzKJ2_lPxZ8

18:40 <jmabsd> jakllsch: i225 is buggy hardware and should never be used, any revision. i226 is the i225 with finally correct fixes to the design.
