AM3352: Build U-boot error

The TI SDK I used is: ti-processor-sdk-linux-am335x-evm-08.02.00.24  (download from TI web).

Uboot source code is: u-boot-2021.01+gitAUTOINC+44a87e3ab8-g44a87e3ab8  (include in the SDK above/board-support/)

Corss Compile is： arm-none-linux-gnueabihf- gcc （include in the SDK above/linux-devkit/sysroots/x86_64-arago-linux/usr/bin）

When I build the U-boot with original "am335x_evm_defconfig", the build is sucessfully,

After I follow the insturctions "software-dl.ti.com/…/U-Boot.html" step to step to set baseline of my own design board, I build the U-boot as follow, but found error:

make ARCH=arm CROSS_COMPILE='arm-none-linux-gnueabihf-' mrproper—— this is O.K.

make ARCH=arm CROSS_COMPILE='arm-none-linux-gnueabihf-' am335x_<myboard>_defconfig——.config is generated sucessfully.

make ARCH=arm CROSS_COMPILE='arm-none-linux-gnueabihf-'——error
