What was somewhat confusing for me, this section continues in the installation guide with: "They are named <system-type>.sdcard.img.gz and can be written to a card e.g. with " The link a few lines further up shows http://http.us.debian.org/debian/dists/bullseye/main/installer-armhf/current/ images/u-boot/MX6_Cubox-i/MX6_Cubox-i.sdcard.img.gz which matches perfectly the naming convention given their for the ready-made SD card images. But if I understood you correctly, I should better use what is referenced in Section 5.1.5. http://http.us.debian.org/debian/dists/bullseye/main/installer-armhf/current/ images/netboot/SD-card-images/ I assume this firmware*.img.gz part contains U-boot as well, correct? And the partition.img.gz contains the installer, correct? Thanks Rainer -- Rainer Dorsch http://bokomoko.de/
