日志
昨天把上篇日志中的问题解决了……
|
第一个问题：
PCY2410 # nand write.yaffs 32000000 300000 2800000
NAND write: device 0 offset 0x300000, size 0x2800000
Input block length is not page aligned
Data did not fit into device, due to bad blocks
41943040 bytes written: ERROR
就是因为上面的2800000没有对齐。yaffs文件系统的block大小为512+16，因此需要对齐。直接使用$(filesize)代替2800000就可以解决这个问题。
这个问题解决了，第二个问题也就解决了。
