Hi,
We are using MPC8640 in our board. During booting we are getting TRAP 200
randomly. Some times it is booting without any issue some times it trapped
into the exception 200 and automatically restarts itself. The PowerPC
archietecture defines TRAP 200 will be due to some TLB miss and related
things. Can you please suggest me how to identify the source of the issue
and solve the problem.
