Hello,
After some try (including checking the right image, the sdcard and the reader), i've managed to boot the Pine64 RockPro64 by doing: - Getting firmware and partition of daily images for RockPro64 and assembling it to complete_image.img - Copy it with dd on sdcard and plug it on board and powering the board. - Using installer normally but instead of using the whole disk I formated the fat32 partition to ext4 and resized to the end of sdcard (to avoiding erasing bootloader at beginning sdcard) - Used chroot on another machine to install flash-kernel and adding [0]: 'Pine64 RockPro64' to /etc/flash-kernel/machine and: Machine: Pine64 RockPro64 Kernel-Flavors: arm64 DTB-Id: rockchip/rk3399-rockpro64.dtb Boot-Script-Path: /boot/boot.scr U-Boot-Script-Name: bootscr.uboot-generic Required-Packages: u-boot-tools To /etc/flash-kernel/db - Using programs on this order: update-initramfs -u flash-kernel After a reboot the board is now working ! Now i would like to write u-boot on SPI flash instead of using sdcard to boot and facilitate me if i need to reinstalling Debian on it. How i can help to bring those features on mainling sdcard images ? Thanks [0] I've sent merge request on salsa for flash-kernel: https://salsa.debian.org/installer-team/flash-kernel/-/merge_requests/21
