On a flash memory with 32KB 17*4882a593Smuzhiyun eraseblocks, 0 means the first eraseblock at 0x00000000, 1 means the 18*4882a593Smuzhiyun second eraseblock at 0x00008000 and so on. 19*4882a593Smuzhiyun 20*4882a593SmuzhiyunExample: 21*4882a593Smuzhiyun 22*4882a593Smuzhiyunflash@0 { 23*4882a593Smuzhiyun partitions { 24*4882a593Smuzhiyun compatible = "redboot-fis"; 25*4882a593Smuzhiyun fis-index-block = <0>; 26*4882a593Smuzhiyun }; 27*4882a593Smuzhiyun}; 28
