recipes-bsp/optee-ftpm: optee-ftpm package needs to be cross compiled #547

Open rakeshk7097 opened 1 month ago

rakeshk7097 commented 1 month ago

optee-ftpm builds successfully only in cross-compilation mode; therefore, setting the recipe to default to cross-compilation can resolve the following build error.

make[2]: Entering directory '/<>/Samples/ARM32-FirmwareTPM/optee_ta' /usr/bin/make -C fTPM CROSS_COMPILE= make[3]: Entering directory '/<>/Samples/ARM32-FirmwareTPM/optee_ta/fTPM' Checking symlink to the TPM folder: /<> Checking symlink to the WolfSSL folder: /<>/external/wolfssl Establishing symlink.

Hi @BaochengSu , could you please review the PR.

This rather looks like an issue that is independent of the recipe in meta-iot2050, rather shared by all that use optee-ftpm.inc from isar. But just dropping it there will also not solve the underlying issue because this would still break on arm64 build hosts - which we kind of supported once.

But why are you running into this at all? Are you actually building inside QEMU?

Actually, I am building on an x86 host machine and attempted to build the optee-ftpm-iot2050 package without setting ISAR_CROSS_COMPILE = 1 in local.conf, but the build process reported an error.

Building only optee-ftpm package for cross-compilation might be beneficial rather than setting ISAR_CROSS_COMPILE = 1 in local.conf and compiling all packages in cross-compilation mode, as is the current practice with meta-iot2050 for enabling secure boot.

What would be your suggestion regarding this matter?
