I want to make some customization on its content without building it from scratch (built in Buildroot).

When I extracted it, the files inside the image shows the following (which is pretty standard): enter image description here

As for Xilinx documentation you can Unwrap the image with the u-boot header.

$ dd if=uramdisk.image.gz bs=64 skip=1 of=ramdisk.gz // It will generate file but still corrupted

To verify the file type of uramdisk.image.gz from this image. enter image description here

Which is way different from what I expected like from other image I've created. enter image description here

They also use uEnv.txt file manually mount the BOOT.bin into specific memory. (correct me if I'm wrong).

$ uenvcmd=dcache off && fatload mmc 0 0x1000000 BOOT.bin && go 0x1000000

// Firmware is working well, so I wouldn't think that its corrupted.

System Information:

  • Virtual machine
  • Ubuntu 18.04 LTS

So here's my questions:

  • Is it possible to change file type of uramdisk into it's original state?
  • Does BOOT.bin contains extra layer of code to read the uramdisk with different file type?

Any suggestions are welcome. Thanks!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
