With v4 of 45/46, this fails with lwIP on Pi in the PXE tests now. You likely don't need more than CONFIG_NET_LWIP=y being added but for completeness here's everything: CONFIG_UNIT_TEST=y # CONFIG_CMD_EFIDEBUG is not set CONFIG_CMD_BOOTMENU=y CONFIG_CMD_LOG=y # CONFIG_CMD_BOOTEFI_SELFTEST is not set CONFIG_IPV6=y CONFIG_IPV6_ROUTER_DISCOVERY=y CONFIG_CMD_TFTPPUT=y CONFIG_CMD_WGET=y CONFIG_FIT=y CONFIG_FIT_SIGNATURE=y CONFIG_FIT_BEST_MATCH=y CONFIG_SYS_BOOTM_LEN=0x4000000 CONFIG_NET_LWIP=y CONFIG_BOOTSTAGE_STASH_ADDR=0x02400000 CONFIG_BOOTSTAGE=y CONFIG_BOOTSTAGE_STASH=y CONFIG_CMD_BOOTSTAGE=y on top of rpi_3_defconfig. -- Tom
