[SOLVED] Problem Flashing with BOOTUTILW64E [FLB File]

[jrsmile]

i get an error when using: BOOTUTILW64E.EXE for flashing iPXE into an Intel® Gigabit-Ethernet-Controller 82574L EXPI9301CT 8086:10d3
with a winbond 25x40 CLING SPI Flash Chip 4M-bit/512K-byte (524,288)

did a git clone today and without modification "make bin/808610d3.rom"

and got the following error:

i have searched for the error and came across some padding tips i tried them even the filesize is correct now.
i tried renaming the file from rom to IBA/iba/flb/FLB.

no success so far.

do i have to use ibautil?
