Follow-ups

--- Mingquan Pan 2009-03-18 02:35:00

It looks with branch toolchain revision 3267, built shared-flat image running on

bf548-ezkit board is ok, but failed with bf537 stamp board. The kernel source is

the same.

--- Jie Zhang 2009-03-19 02:00:10

I cannot reproduce it.

--- Mingquan Pan 2009-03-19 07:11:20

Yeah, it is also ok with 3267 on 537 stamp. Close.
