Hi All,

Sorry for the noise. This issue is reproducible with older toolchains.

This commit gives build error on aarch64-linux-gcc-7 toolchain on U-buntu 18.04 Host machine.

After upgrading the toolchain[1] (version: 9.2-2019.12), it compiles OK. [1] https://developer.arm.com/tools-and-software/open-source-software/developer-...

Cheers, Biju

Hi All,

I am getting compilation error with Mainline TFA on renesas platform for bl31 build.

Build command: #make CROSS_COMPILE=aarch64-linux-gnu- bl31 PLAT=rcar LSI=M3 MBEDTLS_DIR=../mbedtls

Q1) Have any one see this issue? Please correct me, if I am doing something wrong.

On further investigation, the below commit introduced the issue [1]

[1] https://git.trustedfirmware.org/TF-A/trusted-firmware- a.git/commit/plat/renesas/rcar/bl31_plat_setup.c?id=ca661a0092c8ead5ac7 df57c55fffcc835d9c0b9

It gives compilation error " error: initializer element is not constant" for BL_CODE_BASE [2]

[2] https://elixir.bootlin.com/arm-trusted- firmware/latest/source/plat/renesas/rcar/bl31_plat_setup.c#L25

BL_CODE_BASE gets its value from linker in [3] [3] https://elixir.bootlin.com/arm-trusted- firmware/latest/source/include/common/bl_common.h#L106

If you see [4], the initializer element is not constant [4] https://elixir.bootlin.com/arm-trusted- firmware/latest/source/include/lib/utils_def.h#L140
