Message: 52139 posting the crash message is useless if you turn off the hardware trace buffer ... either turn it back on (there's no point in turning it off in the first place), or you'll have to hook up a debugger and figure out where it's crashing

Message: 52147 The above problem is that I modified mtd parts in the mach-bf537/board/stamp.c,so I return to the original stamp.c, it's Ok.

As last question: http://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&forum_id=39&_forum_action=ForumMessageBrowse&thread_id=26189

I wrote my flash driver(flash_test.c) which I refered to bf5xx_flash.c and compiled it. I checked flash_test.o in the directory.

My questions:

Why my flash driver doesn't execute the flash probe,even I add testing prink in the function?

When I selected physmap-flash.0 for my flash driver, why it only have 4M?

With your help, my board can detect the BF5xx_flash now ,but the rootfs -jffs2 still has a problem.

I'm sure that rootfs-jffs2 is written at the right position.
