When we try to build images for machine which is tuned for cortex-a32, then libgcc-initial recipe fails to build with below error message. -- snip -- configure:3529: aarch64-poky-linux-gcc -mcpu=cortex-a32+crc -fstack-protector-strong -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=.../tmp/work/aarch64-poky-linux/libgcc-initial/9.2.0-r0/recipe-sysroot -o conftest -O2 -pipe -g -feliminate-unused-debug-types -fmacro-prefix-map=.../tmp/work/aarch64-poky-linux/libgcc-initial/9.2.0-r0=/usr/src/debug/libgcc-initial/9.2.0-r0 -fdebug-prefix-map=.../tmp/work/aarch64-poky-linux/libgcc-initial/9.2.0-r0=/usr/src/debug/libgcc-initial/9.2.0-r0 -fdebug-prefix-map=.../tmp/work/aarch64-poky-linux/libgcc-initial/9.2.0-r0/recipe-sysroot= -fdebug-prefix-map=.../tmp/work/aarch64-poky-linux/libgcc-initial/9.2.0-r0/recipe-sysroot-native= -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -fstack-protector-strong -Wl,-z,relro,-z,now conftest.c >&5 aarch64-poky-linux-gcc: fatal error: unknown value 'cortex-a32+crc' for '-mcpu' -- snip -- - Replacing TUNE_FEATURES from aarch64 to armv8a will solve the above build issue. - Changed BASE_LIB to 'lib', as cortex-a32 is a 32bit ARMv8a architecture.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
