So I'm creating support for new device mt7981 based with 16MB SPI
I'm getting openwrt-mediatek-filogic-cudy_wr3000-initramfs-kernel.bin
and openwrt-mediatek-filogic-cudy_wr3000-squashfs-sysupgrade.bin
After tftp booting initramfs
sysupgrade -n /tmp/openwrt-mediatek-filogic-cudy_wr3000-squashfs-sysupgrade.bin and this what I'm getting:
