Hi all.

I am trying to port TFM using the corstone1000 platform.

Previously, I was using the 1.7.0 version.  TFM version was recently updated and I am trying to use the 1.8.0 version by downloading it from the site below. https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git

As instructed by the site below  (https://tf-m-user-guide.trustedfirmware.org/platform/arm/corstone1000/readme...)

I executed the command below.

cmake -B build/ -S . -DCMAKE_BUILD_TYPE=Debug -DTFM_TOOLCHAIN_FILE=<tf-m-root>/toolchain_GNUARM. cmake -DTFM_PLATFORM=arm/corstone1000 -DTEST_NS=OFF -DTEST_S=ON -DTEST_S_PS=OFF -DTEST_S_PLATFORM=OFF -DEXTRA_S_TEST_SUITE_PATH=platform/ext/target/arm/corstone1000/ci_regression_tests/

However, I got a cmake error as shown below.

- Build type: Debug -- Host: Linux/x86_64 -- Target: Generic/arm -- Machine: template -- Host: Linux/x86_64 -- Target: Generic/arm -- Machine: template -- C_FLAGS : -mcpu=cortex-m0plus -Wall -Wextra CMake Error at platform/ext/target/arm/corstone1000/CMakeLists.txt:144 (target_sources):   Cannot specify sources for target "platform_bl1" which is not built by this   project.

CMake Error at platform/ext/target/arm/corstone1000/CMakeLists.txt:168 (target_compile_definitions):   Cannot specify compile definitions for target "platform_bl1" which is not   built by this project.

CMake Error at platform/ext/target/arm/corstone1000/CMakeLists.txt:175 (target_include_directories):   Cannot specify include directories for target "platform_bl1_interface"   which is not built by this project.

I think this is caused by the target for platform_bl1 not being specified, but I don't know how to fix it.

I executed cmake using the same configuration as set in corstone1000's config.cmake.

Can anyone tell me why I am getting the above error?

Any advice would be very helpful.

thanks you.
