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
