我想打开YAFFS中提供的任何调试工具.我希望它能帮助我调试使用闪存时出现的问题.
linux内核中是否有任何配置可以帮助我调试YAFFS？
提前致谢.

解决方法:

根据文件有：

Yaffs has a lot of built in tracing to help deBUG and integrate. The
tracing is controlled by yaffs_traceMask bitmask which allows varIoUs
sets of tracing to be Disabled or enabled at runtime.

The trace bits are specifIEd in the yaffs_trace.h file.

The tracing mechanism has also been ‘hijacked’ to provIDe a control
mask for extra verification code when the YAFFS_TRACE_VERIFYxxx trace
bits are selected.

The tracing mechanism is readily integrated into the system via
printf-like statements. Tracing is all done through macros which allow
the strings to be converted into unicode or similar if need be.

它可以在运行时通过proc或sysfs接口进行 *** 作,例如：

cat +os > /proc/yaffs # Enables YAFFS_TRACE_OScat -all+gc > /proc/yaffs # disables everything then enable YAFFS_TRACE_GCcat 0xf000 > /proc/yaffs # Set trace mask to specifIEd bitmask.
