There are different methods to boot linux on a Xilinx device and one of them is using an SD memory card where the boot files are written. The memory must be formatted in a specific way so that the FPGA can boot from it. Here are the instructions to perform this operation (all to be executed as root):
- Insert the memory card
- Check how is seen by the system: > ls /dev/ (could be /dev/sdb1 or similar; disk4s1 on mac)
- Enter in fdisk > fdisk /dev/sdb
- Press p to check the existing partitions
- Press d to remove all the partitions
- Press n to create a new partition
- Select it as primary
- Use the default start sector
- Set the size between 512 MB and 2 GB using the command +2G (to set a size of 2GB)
- Press a to set it as a bootable partition
- Press n to create a second partition
- Use the default start sector
- Use the default end sector to get all the remaining space
- Press w to write the modification on the SD card
- Remove the SD card and reinsert it into the reader
- Check that now linux sees 2 new devices using the command > ls /dev/ (it could be sdb1 and sdb2)
- Format the first as FAT 32 called boot using the command >mkfs.vfat -F 32 -n boot /dev/sdb1
- Format the first as ETX4 called root using the command >mkfs.ext4 -L root /dev/sdb2
- Remove the SD and reinsert once again. Now Linux should mount two new devices.

Then copy the files into the partitions https://cernbox.cern.ch/index.php/s/bNYR9LgVA8cSeXu :
- root partition: tar -xvf /path/to/uscale_debian11-2.tar.gz -C /path/to/root/
- boot partition: BOOT.BIN and image.ub
These instructions should be scripted so that we can do a full productions of such cards.
