FV is defined in the PI Spec as a layout for flash that contains files= , but no directories. 

Hi Andrew,

 

I forgot to mention earlier, that I'm developing for RISC-V architecture= .

It seems like the semihosting lib in edk2 does not have support for RISC= -V yet.

 

Thanks for the FvSimpleFileSystemDxe suggestion.

Actually, I'm trying to TFTP "initramfs" (1MB) and "linux.efi" (25MB) in= to a filesystem. So, it requires to support write to the filesystem. <= /p>

 

Do you have other suggestions?

 

Thanks! =3D)

John
