Hello, The initial is only to let the USB disk to have a FAT32 file-system at the beginning. Surely it is not necessary. If you dont initialize it, the initial content inside the USB disk is random and invalid, just like a corrupted USB disk (since the un-initialized data in FPGA BRAM is random). At this point, You only need to format it. However, since BRAM will lose data when power-down, every time you power on the FPGA, you need to reformat it.
