I am trying to deploy an ARM operating system using XCAT. My server is an x86 server with system version Rocky8.10, and my client's system is ARM. I also want to deploy the ARM version of RCOKy8.10, but after configuring everything, I encountered the following problem (as shown using RCONS monitoring):

**>>Start PXE over IPv4
Mac Addr: 44-A1-91-E5-33-A5.
Station IP address is 172.16.1.104
PXE ScanEfiPostfix not found the .efi postfix, So get the speacial file
TFTP error code 256

Server IP address is 172.16.1.101
NBP filename is grubaa64.efi
NBP filesize is 0 Bytes
PXE-E23: Client received TFTP error from server.
ERROR: C40000002:V03051002 I0 6D33944A-EC75-4855-A54D-809C75241F6C 33281518**

In order to investigate whether it is a problem with my server, I deployed another x86_64 client machine using the same service node, installed the rocky8.10 operating system, and also used grub2 to successfully install it.

Can I gain some experience or methods？
