I knew CONFIG_SPL_BUILD value is supposed to be set by the build system (Makefille, during spl build).

But I found I had "config SPL_BUILD" with default "y" under my Kconfig in the board directory.

Because this value was always "y", the board_init.c under common/init and some other files were not compiled.

So I removed the SPL_BUILD in the board's Kconfig.

Thanks.

Hello all,

I'm new to u-boot and having difficulty while trying to build u-boot for our test board.(arm64, armv8)

I wanted to try the "SPL falcon" mode". The DDR is not ready yet in the board.

A small scp chip(cortex-M7) will initialize clk and will load kernel(including initramfs), dtb, u-boot-spl, images to a small internal RAM.

And the AP chip will start from the u-boot-spl. (I know some low-level init can be skipped)

I added SPL related config settings and ran this command.

make CROSS_COMPILE=aarch64-none-elf- ab21m_defconfig

make CROSS_COMPILE=aarch64-none-elf-

I see "u-boot/arch/arm/lib/crt0_64.S:88: undefined reference to `board_init_f_alloc_reserve'" error during the u-boot build. (not related to SPL).

By comparing the build process with that of rk3036 board (arm board with SUPPORT_SPL, no SUPPORT_TPL), I found in my case even common/board_init.c is not compiled.

Where should I look? I'm reading the documents or build scripts here and there but can't figure it out.

Thank you.
