Hello, Our BSP is currently defining:
TARGET_EXTRA_CFLAGS=-mtune=cortex-a7 -mfpu=neon-vfpv4 However this is causing us some trouble with TF-A, as the code generated by the toolchain contains NEON instructions, which makes it fail at runtime with "Undefined instruction" exceptions. We could skip this for TF-A specifically by adding TARGET_EXTRA_CFLAGS to TF_A_WRAPPER_BLACKLIST. But actually we'd like to do the same for all low level code, including kernel and bootloaders (U-Boot, OP-TEE). Since all of these already set <package>_WRAPPER_BLACKLIST to $(PTXDIST_LOWLEVEL_WRAPPER_BLACKLIST), the easiest and more robust way would be to add TARGET_EXTRA_CFLAGS to PTXDIST_LOWLEVEL_WRAPPER_BLACKLIST itself. Is this possible? Thanks, Guillermo Rodriguez Garcia [email protected]
