Hello, With ubuntu-device-flash I used to be able to specify exactly where the bootloader binaries were located in the final disk image. I needed this because my device has eMMC operating in RAW mode, rather than an SD card, and the binaries have to be in specific locations for the processor to find them on boot-up. For example my MLO needs to be at an offset of 131072 bytes from the start of the disk image.
With ubuntu-image, in the gadget snap, I can only specify the 'offset' as a multiple of 1MB. Anything less and the binaries all appear at the start of the disk image. The 'offset-write' would seem to be the solution, but this doesn't seem to actually locate the binary at the specified offset in bytes, it just writes a 32 bit value which is the location specified by 'offset'. I may have misunderstood something, but does anyone know how I can get ubuntu-image to put my binaries where I need them? Thanks. -- Devices mailing list Devices@lists.snapcraft.io Modify settings or unsubscribe at: https://lists.snapcraft.io/mailman/listinfo/devices
