Hi Joan,
Based on the link you provided, I downloaded this file(L4.1.15_GA1.2.0_uboot_logo_keep_patch_2017-01-06.zip).
Based on this file, I tried to patch the u-boot patch file to u-boot in L4.1.15_2.0.0_ga. Then I run u-boot image on the demo board, the system will always restart.
Such as the following message:
