mkfs.jffs2 옵션에 -x를 주면 압축을 안하는 듯?
jffs2를 압축하면 실시간으로 계속 압축 / 해제 하니까 저사양 cpu에서는 무리가 올테니..
나중에 한번 부팅속도 라던가 벤치마크 해보거나
벤치마크 결과를 찾아봐야겠다.
-m, --compression-mode=MODE Set the default compression mode. The default mode is priority which tries the compressors in a predefinied order and chooses the first successful one. The alternatives are: none (mkfs will not compress) and size (mkfs will try all compressor and chooses the one which have the smallest result). -x, --disable-compressor=NAME Disable a compressor. Use -L to see the list of the avaiable compressors and their default states. -X, --enable-compressor=NAME Enable a compressor. Use -L to see the list of the avaiable compressors and their default states. -y, --compressor-priority=PRIORITY:NAME Set the priority of a compressor. Use -L to see the list of the avaiable compressors and their default priority. Priorities are used by priority compression mode. -L, --list-compressors Show the list of the avaiable compressors and their states. -t, --test-compression Call decompress after every compress - and compare the result with the original data -, and some other check.
