Hello Jerome,
Using the old network stack U-Boot's dhcp command can be used to
download via TFTP. This fails with the lwIP stack:
StarFive # dhcp $kernel_addr_r 192.168.1.103:/vf2/grubriscv64.efi
ethernet@16030000 Waiting for PHY auto negotiation to complete.... done
DHCP client bound to address 192.168.1.47 (233 ms)
StarFive # tftpboot $kernel_addr_r 192.168.1.103:/vf2/grubriscv64.efi
Using ethernet@16030000 device
TFTP from server 192.168.1.103; our IP address is 192.168.1.47
Filename '/vf2/grubriscv64.efi'.
Load address: 0x40200000

We should try to provide the old functionality to make the move to lwIP
seamless.
In the CI QEMU instances we already have
test/py/tests/test_net.py
to test tftpboot. We should add an equivalent dhcp test.
Best regards
Heinrich
