[edk2-devel] Setting a static IP address in EDK2 Payload prior to UEFI Shell

Hi,

Within EDK2 payload, I am trying to get a static IP address set, so that when I enter UEFI Shell, I can ping another computer.

At the moment I have the network stack elements started automatically, but still need to type 'ifconfig -s eth0 static 192.168.1.5 255.255.255.0 192.168.1.1' every time to get the IP address assigned before i can ping 192.168.1.10

I'd like to start the UEFI shell and just run the ping command, and it check if 192.168.1.10 is available.

The current versions of EDK2 and Slimboot from github I am using are listed below

EDK2 - d13f31c3fe17eb532bf9016a2d8de3885642cba0 (https://github.com/tianocore/edk2/tree/d13f31c3fe17eb532bf9016a2d8de3885642cba0) from September 30th (I tried a newer version, but got build errors)
Slimboot - ca00703127e34c84c3e6d3d129ebc5ef292ba963 (https://github.com/slimbootloader/slimbootloader/tree/ca00703127e34c84c3e6d3d129ebc5ef292ba963) from October 25th

I've tried the following...

but loading the INF file into sbl_02\edk2\UefiPayloadPkg\UefiPayloadPkg.dsc and sbl_02\edk2\UefiPayloadPkg\UefiPayloadPkg.fdf caused the build binary to not load.

I commented out the above entries and then modified sbl_02\edk2\UefiPayloadPkg\UefiPayloadPkg.dsc and sbl_02\edk2\UefiPayloadPkg\UefiPayloadPkg.dec

I added into the dsc the following

# Disable DHCP
gUefiPayloadPkgTokenSpaceGuid.PcdIPv4Enable|TRUE
gUefiPayloadPkgTokenSpaceGuid.PcdDhcp|FALSE

# Static IP configuration for eth0
gUefiPayloadPkgTokenSpaceGuid.PcdIp4Address0|192.168.1.5
gUefiPayloadPkgTokenSpaceGuid.PcdIp4SubnetMask0|255.255.255.0
gUefiPayloadPkgTokenSpaceGuid.PcdIp4Gateway0|192.168.1.1

In the dec I added

[PcdsFixedAtBuild]
gUefiPayloadPkgTokenSpaceGuid.PcdIPv4Enable|TRUE|BOOLEAN|0x00000001
gUefiPayloadPkgTokenSpaceGuid.PcdDhcp|FALSE|BOOLEAN|0x00000002
gUefiPayloadPkgTokenSpaceGuid.PcdIp4Address0|192.168.1.5|VOID*|0x00000042
gUefiPayloadPkgTokenSpaceGuid.PcdIp4SubnetMask0|255.255.255.0|VOID*|0x00000043
gUefiPayloadPkgTokenSpaceGuid.PcdIp4Gateway0|192.168.1.1|VOID*|0x00000044

This booted into UEFI shell, but didn't assign the IP address.

I will have multiple interfaces i need to set static IP addresses to, but eth0 is of course the first :-)

Any help gratefully received.

Kind regards
