Dear "Thirumalai",
In message 8F0ECFAA4F2C46928A69DE95FAF2A07B@itd210 you wrote:
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.
Sorry. Trap 200 is Machine check exception. Also sometimes we are getting TRAP 300 which is DSI exception.
Did you try booting Linux on that board? Let me guess: if you tried, it crashed, right?
No. It is not crashing. Linux is booting on this board successfully. Its a random issue.
I recommend to check the RAM initialization sequence. I bet you see memory corruption effects.
What you meant for memory corruption effects?
Best regards,
Wolfgang Denk
