Dear openbmc, now I use the openbmc public image to test on my evb board. the fitImag rootfs used aspeed-image-initramfs-evb-ast2500.cpio.xz. but for obmc-phosphor-image-evb-ast2500-20200511083309.rootfs.tar.gz not used! I unzip the obmc-phosphor-image-evb-ast2500-20200511083309.rootfs.tar.gz and find many feature here. now I want to used this rootfs. but when I used it as the rootfs to replace aspeed-image-initramfs-evb-ast2500.cpio.xz. Then it can not boot up anymore! So would u please tell me how to use the obmc-phosphor-image-evb-ast2500-20200511083309.rootfs.tar.gz. Or just give me some clue on this! Thanks Steven
