Hi,
I'm trying to install OpenBSD on a NanoPi R2S, but I'm having difficulties to define the correct block sizes for the *dd* to command to write the .img file into the correct spot. The OpenBSD manual at https://ftp.openbsd.org/pub/OpenBSD/.../INSTALL.arm64 <https://ftp.openbsd.org/pub/OpenBSD/snapshots/arm64/INSTALL.arm64> lists the following two steps: For systems based on Rockchip RK33xx SoCs: dd if=/usr/local/share/u-boot/board/idbloader.img \ of=/dev/sdXc seek=64 dd if=/usr/local/share/u-boot/board/u-boot.itb \ of=/dev/sdXc seek=16384 I cannot get a working miniroot install following those two steps. Someone uploaded this little asciinema of a fresh OpenBSD install on the same board https://asciinema.org/a/381973 The ascii shows a third command of copying some other .bin file: dd if=usr/lib/linux-u-boot-current-nanopi-r2s_20.11.3_arm64/trust.bin of=/dev/sdc seek=24576 conv=notrunc Since releases differ in size, I need to know how to calculate this offset for the current trust.bin given the miniroot70.img Help is greatly appreciated!
