Alpine Linux on the Duo?

boba · October 8, 2023, 5:59pm

I’ve been messing around with Alpine on the Raspberry Pi Zero as of late for a personal project. Has anyone here tried getting Alpine running on the Duo? I imagine it would run a bit slower than the Buildroot, but could be more capable.

I build the image, loop mount, and then replace rootfs with alpine. (need to copy many files and lib from the original image to alpine) The result is quite perfect.

Do you think you can upload the image to GitHub or somewhere else? Thanks.

Let me refine some parts of it, then I will upload my final image.

@boba here the image and instruction. Release Proof of Concept 1 · cwt/duo-buildroot-sdk · GitHub

Thanks! I’ll be sure to check it out when I get the chance…

I tried it - thanks!

My feedback:

rndis works, see my persistent MAC addresses here: https://xyzdims.com/3d-printers/misc-hardware-notes/iot-milk-v-duo-risc-v-esbc-running-linux/#Static_IP_for_Host_with_RNDIS which you might include
I had to use apk [add|update] --no-check-certificate otherwise installations fail

I tried Ubuntu (as posted in Ubuntu on the milk-v duo) but apt is really slow, so for now ArchLinux and AlpineLinux are the best choices with a decent package manager.

may be you ran it before the RTC was set? I will take some time after boot to be able to get time from the NTP server.

I didn’t use rndis much, but I use ethernet on the IO board. I added this file:

milkv-duo:~# cat /etc/network/if-pre-up.d/set_eth0_mac 

#!/bin/sh

if test -d /sys/class/net/eth0; then
	ifconfig eth0 down
	ifconfig eth0 hw ether XX:XX:XX:XX:XX:XX  # <-- there should be some algorithm to ensure that this MAC is unique and without overlapping any some well-known manufacturers?
	ifconfig eth0 up
fi

Just apk update && apk upgrade today, there is something wrong with clang-17:

milkv-duo:~# clang

while dmesg show this:

I guess that the instruction code in libLLVM-17.so contains something that cannot be executed on Duo.
