Hi guys, i’m trying create a arm64 UC image, refer to ubuntu.com/core/docs/image-building and sample gadgets on github.com/snapcore. the UC18 image create successful and bootup well, but failed for creating UC20 image. I followed the kernel-build guide ubuntu.com/core/docs/kernel-building to build the kernel snap and then create a UC20 image, but boot hang at initrd because the initrd is an UC18 type which is not used for UC20.
So how can i build the kernel snap with UC20 initrd for UC20 image? is this github.com/snapcore/core-initrd the source code for UC20 initrd? if so, how to build it and integrate with kernel snap build?
