Search them on github website

Thanks Yoshinoya for your input. =3D)

 

I have tried to compile the filesy= stem into my FD image as a separate FV. Then building FV HOB with it using = "BuildFvHob".

Next, using the "GetSectionFromAnyFv" to load the files= ystem into buffer as follow:

<dummyfile.0.part>

Finally, create a d= isk with the filesystem buffer created earlier. 

<dummyfile.1.part><= /p>

This works without having to create filesystem in EDK2. Instead loadi= ng it from somewhere else.

However, this method has some limitations = because the maximum size of each SECTION in FFS is only 16MB.

<dummyfile.2.part>=

Thus, I still couldn't TFTP Linux (~25MB) into my filesystem = "FS0:"

 

My sol= ution:

<= dummyfile.3.part> <dummyfile.4.part>

1. Allocate buffer

2. Populate the buffer by with100MB FAT16 header

3. Register virt= ual disk with the buffer

 

I'm able to allocate 100MB of FAT16 filesystem and TFTP Linux s= uccessfully:
&= lt;dummyfile.5.part>

<dummyfile.6.part>

 

Thanks everyone!!

John
