This section provides guidance for managing flash media and images.
Writing Images for SD Card
The EDF prebuilt image is delivered as feature rich, and is too big
for using initramfs method to temporary mount the
file system on RAM. Preferred mount options for the image file systems involve SD
card or other flash media directly. EDF provide several alternatives to prepare the
media so Vitis package is no longer creating the SD
card files. Instead this is done using wic together
with mtools which provide commands to directly add,
copy, and modify image partitions before writing the image to SD card or other flash
media.
For descriptions and details how to use wic refer to AMD
EDF Disk Image Layout
Writing Images to the OSPI, QSPI and other Media
Both single and multi-stage boot can be setup on various media depending on customer requirements. AMD EDF prebuilt images for AMD development boards use multi-stage boot with deferred PL load as default. For more details and descriptions on default and alternative image setup, refer to AMD EDF Common Specifications
