Hello Kevin, These are the changes that would be necessary in uboot mainline for SPL:
arch/arm/cpu/armv7/exynos/Kconfig
select OF_CONTROL
select SUPPORT_SPLselect OF_CONTROL if !SPL_BUILDconfigs/odroid-xu3_defconfig +CONFIG_SPL=y
include/configs/odroid_xu3.h #undef CONFIG_SPL_TEXT_BASE #define CONFIG_SPL_TEXT_BASE 0x02027000
#undef CONFIG_SEC_FW_SIZE #define CONFIG_SEC_FW_SIZE (15 << 10) /* 15 KB */
Thanks. With those changes, a build gives me:
./include/common.h:355:73: fatal error: asm/u-boot-sandbox.h: No such file or directory
Sorry for the dumb questions, but I'm not very familiar with u-boot. I'm more comofortable in the kernel.
The above used to work (a month ago). I shall check with current mainline uboot and report back.
Sorry for the snafu. I t was my mistake. The correct diff for the configs is as below:
diff --git a/arch/arm/cpu/armv7/exynos/Kconfig b/arch/arm/cpu/armv7/exynos/Kconfig index 7fcb5d2..39953e4 100644 --- a/arch/arm/cpu/armv7/exynos/Kconfig +++ b/arch/arm/cpu/armv7/exynos/Kconfig @@ -26,7 +26,8 @@ config TARGET_ODROID

Thanks, that gets things building. Just to double-check, no additional changes to include/configs/odroid_xu3.h?
Also, which image are you using as your unsigned BL2? spl/u-boot-spl.bin or spl/smdk5420-spl.bin?
The later seems to be generated from the former using tools/mkexynosspl, but not sure exactly what it's doing, or if its needed on all boards or just the smdk5420 (as the name implies).
Thanks,
Kevin
