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. Chan Kim
