I'm OK with either solution, but I wonder whether it would be a better idea to regenerate psu_init_gpl.c (and pm_cfg_obj.c while there) using Vivado 2022 and mainline them in U-Boot. Would that fix the issue as well? Vivado is assumed to generate correct files, if it didn't in the past, chances are it has been fixed in the meantime. -- Luca _______________________________________________ buildroot mailing list buildroot@buildroot.org https://lists.buildroot.org/mailman/listinfo/buildroot
