Hi Ovidiu,
Thank you so much, with those two configs added, u-boot-spl was finally built ok (The remaining 3 or 4 link errors are all gone together) Thank you,
Best regards, Chan Kim

Hello,
When I build u-boot, I get this error at the end. (during u-boot-spl
build).
I've been fixing some link errors by adding config values but I can't figure out what is wrong with this.
Below is the final command for u-boot-spl build and the error messages.
Can any expert tell me what can be wrong here?

Could you try to enable CONFIG_SPL_LIBCOMMON_SUPPORT and CONFIG_SPL_LIBGENERIC_SUPPORT Kconfig options?
Ovidiu
Thank you.
