Please compile using this configuration.


Build in the shell environment where toolchain is installed.

1.Execute the following command in the toolchain directory: 
source environment-setup-cortexa7hf-neon-vfpv4-poky-linux-gnueabi 

2.Use the cd command to directly jump to the Linux kernel directory and execute the following command to compile:
cmd1:
make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- KCFLAGS="-Wno-missing-attributes -Wno-misleading-indentation -Wno-array-parameter -Wno-address-of-packed-member -Wno-stringop-truncation -Wno-attribute-alias -Wno-packed-not-aligned -Wno-stringop-truncation -Wno-stringop-overflow -Wno-array-bounds -Wno-maybe-uninitialized -Wno-shift-count-overflow -Wno-pointer-to-int-cast -Wno-int-to-pointer-cast -Wno-format-extra-args -Wno-format -Wno-comment -Wno-uninitialized -Wno-bool-compare -Wno-sizeof-pointer-memaccess -Wno-unused-variable" aud8518sp2-slc-32b-7921-c4a-user_defconfig
cmd2:
make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- KCFLAGS="-Wno-missing-attributes -Wno-misleading-indentation -Wno-array-parameter -Wno-address-of-packed-member -Wno-stringop-truncation -Wno-attribute-alias -Wno-packed-not-aligned -Wno-stringop-truncation -Wno-stringop-overflow -Wno-array-bounds -Wno-maybe-uninitialized -Wno-shift-count-overflow -Wno-pointer-to-int-cast -Wno-int-to-pointer-cast -Wno-format-extra-args -Wno-format -Wno-comment -Wno-uninitialized -Wno-bool-compare -Wno-sizeof-pointer-memaccess -Wno-unused-variable"  olddefconfig
cmd2:
make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- KCFLAGS="-Wno-missing-attributes -Wno-misleading-indentation -Wno-array-parameter -Wno-address-of-packed-member -Wno-stringop-truncation -Wno-attribute-alias -Wno-packed-not-aligned -Wno-stringop-truncation -Wno-stringop-overflow -Wno-array-bounds -Wno-maybe-uninitialized -Wno-shift-count-overflow -Wno-pointer-to-int-cast -Wno-int-to-pointer-cast -Wno-format-extra-args -Wno-format -Wno-comment -Wno-uninitialized -Wno-bool-compare -Wno-sizeof-pointer-memaccess -Wno-unused-variable"  -j$(nproc) 

3.When Compile OK, generate vmLinux files in the Linux kernel directory
