Re: [leaf-user] Raspberry pi computer module 5 on a CM5-DUAL-ETH-MINI

   Jeanrocco,

   I'm curious if you have tested the throughput of this combination
   outside of Leaf?
   Looks interesting!

Hello list,

I was just wondering if anyone has looked at this combination of a 50$ dual
ethernet module with a ~125$ Pi CM5 module. The speed is interesting: from

base board delivers full gigabit speeds (up to 1000Mbps) across its dual
RJ45 ports, with Ethernet 0 running on the native CM5 controller and
Ethernet 1 running via an extended PCIe RTL8111H Gigabit NIC chip

.

Installing LEAF on this requires some recompiling though:
Because the precompiled LEAF images do not natively bundle the BCM2712
kernel or the specific Realtek PCIe Ethernet drivers out of the box,
flashing a standard Raspberry Pi LEAF image will likely result in a failed
boot or an unrecognized second network interface.

The AI also tells me:
If you are determined to use LEAF for its excellent memory-resident
properties and Shorewall packaging, you must cross-compile it yourself.
.  You will need to download the LEAF source tree and modify its toolchain
configuration to compile against the official Raspberry Pi Linux Kernel tree
[8]<https://github.com/raspberrypi/linux> targeting bcm2712.
. Ensure that the CONFIG_R8169 or CONFIG_RTL8111 driver is compiled
directly into the kernel image (not just as a dynamic module) so that the
second Ethernet port initializes correctly on boot.

According to the same AI (Google's) OpenWrt and IPFire already provide a
native support.

The AI also explains all the steps to compile everything but I was
wondering if LEAF would be willing to go that way.

Just a thought :-)

Bye
Jeanrocco
