Assert when trying to run ATF with FVP foundation model

[ruchi393]

Hi,

I am following instructions in the ATF user guide for running ATF via FVP foundation model.

I get the following assert while doing so :
ASSERT: lib/xlat_tables_v2/aarch64/xlat_tables_arch.c:64

Can someone help on what could be going wrong over here ?

FVP model being used -
Foundation_Platform --version
ARM V8 Foundation Platformr0p0 (platform build 11.2.33)
Copyright 2017 ARM Limited.

ATF images being built from following commit ID

@ruchi393
What build command / options are you using?

If you aren't specifying the version of the architecture that the model is emulating, it defaults to the highest one it can emulate. The field PARANGE of register ID_AA64MMFR0_EL1 gained a new value in 8.2. The model uses the max value that PARANGE supports on the architecture. If the model is running at version 8.2 or higher, it will use the new value introduced in 8.2. If you don't compile the TF for version 8.2 or higher, it won't know about this extra value and you will hit this assert.

Your options are:

• Run the foundation model with --arm-v8.0 or --arm-v8.1.
• Compile the firmware with ARM_ARCH_MAJOR=8 and ARM_ARCH_MINOR=2 or higher.

Hi @antonio-nino-diaz-arm

If what you say is correct, then the model parameters in the user guide are wrong. This should be fixed!

Hi,

Thanks for the help. The assert goes away if --arm-v8.0 is added when launching FVP.

As per the user guide, I have picked up imaged from Linaro release. I used workspace_1801.py from the link https://community.arm.com/dev-platforms/w/docs/226/old-linaro-release-note. I have tried both pre-built as well as build options. However, I don't see a uboot or linux prompt coming up. (This pre built release also gives the same assert error)

Can someone please help point to the images which I should pick up from Linaro which would work with this FVP model.

Regards,
Ruchika

I'll update the instructions of the User Guide, @danh-arm.

We are using Linaro Release 17.10, @ruchi393, could you see if that one works for you, at least?

Edit: The patch to update the User Guide is here: ARM-software/arm-trusted-firmware#1281
