how to enable network on FVP

Hi Simon,

my FVP version is Linux64_GCC-4.7, "ARM V8 Foundation Platformr0p0 (platform build 10.3.26)".

command line :

run-only:
@cd $(FOUNDATION_PATH); \
$(FOUNDATION_PATH)/models/Linux64_GCC-4.9/Foundation_Platform \
--arm-v8.0 \
--cores=4 \
--secure-memory \
--visualization \
--gicv3 \
--data="$(ARM_TF_BIN_PATH)/bl1.bin"@0x0 \
--data="$(ARM_TF_BIN_PATH)/fip.bin"@0x8000000 \
--block-device=$(BOOT_IMG) \
--network=nat \
--network-nat-subnet=10.0.2.0/2300 \
--network-nat-ports=8022=22

As I am not familiar with linux and net development, I just use a All in one script for building and running the 

software stack based on optee, linux, fvp, uefi, etc.

OP-TEE/build

As you can see, the default FVP version required by the script is "Linux64_GCC-4.9". I work around this by just adding a

directory named "Linux64_GCC-4.9" and copying the actual executable file under directory  "Linux64_GCC-4.7"

Also, my FVP host is standard ubuntu 16.04 with a IP 10.0.2.15,

I have tried several combinations of the following parameters, and nothing changed.

--network=nat \
--network-nat-subnet=10.0.2.0/2300 \  
--network-nat-ports=8022=22

according to your analysis, maybe I should try another FVP

I am very appreciative if you can give some more advice based on the info above.

thanks

I would recommend updating the model to the latest version (from https://developer.arm.com/products/system-design/fixed-virtual-platforms, it will be verison 11.2) but I doubt this is causing your issue, it is much more likely to be a SW issue.

I've followed the same instructions and had the same output, so I can confirm you are not doing anything wrong but network support on this particular SW stack is not working.
Based on the fact that the configuration does not allow for the --network option to be provided by default, I would assume this configuration has not been tested and is not the purpose of this script.

If you really need this SW stack, I would suggest contacting Linaro, otherwise you could use the SW stack described in https://community.arm.com/dev-platforms/b/documents/posts/using-linaros-deliverables-on-an-fvp .
