問題如下：
squashfs: SQUASHFS error: Filesystem uses "zlib" compression. This is not supported jffs2: Flash size not aligned to erasesize, reducing to 31296KiB jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000000: 0x7368 instead jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000004: 0x030b instead jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000008: 0x23bd instead jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000010: 0x0012 instead jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000014: 0x0001 instead jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000018: 0x00c0 instead jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0000001c: 0x0004 instead jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000020: 0x0e07 instead jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000028: 0xd95e instead jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000030: 0xd956 instead
解法如下：
將SQUASHFS改成xz壓縮方式或者在Kernel選項支援zlib壓縮格式
