Re: FDF file syntax question?

Andrew:
  So, this requests not to set FV size same to FD region size when this FV is placed into FD region. I think one way to do it. In [FD] section, FILE statement is used to point to the generated XXX.Fv image. And, [FV] section includes this FV block size and base address, but no block number. But, I suggest you submit one feature request in Bugzilla for BaseTools. We can enhance BaseTools to support this usage model. 

Thanks

Subject: [edk2] FDF file syntax question?

Is there a way to make the FV defined in the FD section be only big enough to contain the data? The remaining area could be 0xFF (erase value). If the FV is read only there is no point reading the extra data from the FLASH device if all the bytes are 0xFF. 

For example if we make an FV to be compressed the [options] section in the Build output only has the block size, but if it comes from the FD section then you get a base address and block count. 

Thanks,

Andrew Fish
