Device can't connect to server

[mortenboye]

I've been following the setup guide to install CM4 Provisioning on a Pi4 in order to flash CM4 on a custom board.

CM4 is connected via Ethernet to a (non managed) switch connected to the Pi4, as per the instructions, but the provisioning server never detects the CM4.

A project is created and an image is uploaded and ready.

In the dnsmasq log I see this:

...

With a new entry of DHCP packet received on eth0 which has no address every time the CM4 retries PXE boot.

cat /etc/dhcpcd.conf gives me:

interface eth0
static ip_address=172.20.0.1/16

(Instructions says "add ... to the bottom of the file", but the file was empty to begin with?)

cat /var/lib/cmprovision/etc/dnsmasq.conf results in:

# No DNS
port=0

# tftp
enable-tftp
tftp-root=/var/lib/cmprovision/scriptexecute

# dhcp
dhcp-match=set:client_is_a_pi,97,0:52:50:69:34
dhcp-match=set:client_is_a_pi,97,0:34:69:50:52

pxe-service=tag:client_is_a_pi,0,"Raspberry Pi Boot"
dhcp-leasefile=/var/lib/cmprovision/etc/dnsmasq.leases
no-ping

And the CM4 keep trying to boot like this:

Any clues as to how to fix this? Did I miss something obvious?

At the end of the guide it is mentioned that the CM4 bootloader FW might be out of date. How to check this?

Instructions says "add ... to the bottom of the file", but the file was empty to begin with?

It's easiest if you start over with the previous RPI OS version, 64-bit edition. Available with Imager under "Raspberry Pi OS (other)" -> "Raspberry Pi OS (Legacy, 64-bit)"

The new RPI OS version uses NetworkManager instead of dhcpcd, and needs new instructions to setup a static IP address.

You were right. Reinstalled with the legacy version and now it works wonderfully.

Thank you.
