Programming the Si5381 on a ZCU670 board

[Mich1Ros]

Good morning, in order to load the clock files without the "boardui" tool we follow the procedure described in https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/2416869377/Programming+the+Si5381+on+a+ZCU670+board.
We tried to create an application project using both the 'hello world' template and the 'FSBL' one.
For both we tried to put the files "Si5381A-zcu670_......-Registers.h", "Si5381A-programming.c" and "Si5381A-programming.h" (created in order to call the function) inside the "zynqmp_fsbl" folder and also in the application project "src" folder, and we add this part in the xfsbl_hooks.c:
u32 XFsbl_HookBeforeHandoff(u32 EarlyHandoff)
{
u32 Status = XFSBL_SUCCESS;

ProgramSi5381();

return Status;

}
The clocks are not loaded in this way.
Can you help us?
