Raspberry Pi OS • [RPi5] Network boot (DHCP yes TFTP no)

Hi,

Yesterday I tried to boot from the network.

While booting, the Pi shows the IP address of the DHCP server, the IP address of the Pi itself (from DHCP) and the IP address of the TFTP server.
After trying to boot and failing the Pi boots from NVME disk (next in the boot order 612, there is no SD card)
The current and latest eeprom are the same (May 8th 2025).

Can't find anything in logs or with wireshark. Wireshark shows the DHCP packet.

On the TFTP server there is a directory named "serial number (8 digits)" containing the boot partition files.
On the NFS server there is a directory containing the root partition files.

On the DHCP server only the IP address of the TFTP server is specified. No filename.
Should I specify a TFTP filename? If so, which one?

The cmdline.txt options I saw online are slightly different so I'm not sure the ones I'm using are correct.
The NFS root partition is specified.

At least I would expect the Pi to download a file from the TFTP server.
How do I debug this?
