MPC8544 bootloader keep printing debug message over and over

[duckycool]

Hi everyone,

    I'm working on a bootloader of customized board of MPC8544.

    I use the code base of MPC8544DS (demo board) in the LTIB to porting to my board.

    The major difference of my board is that there is no south bridge.

    And I use different memory DIMM from the demo board.

    Could anyone help to check the debugging message from UART as attached files ?

    It keep printing over and over and just can't stop.

    Anyone met this before ? Could you help to provide your experience how to fix it?

    Thanks.

Did you brake anything? When it started?

Hi gleb.itech,

   No, I don't think I brake anything....

   Why you said so ? Could you tell me your what you think it is...?

   Thank you.

I've got something like that when I misconfigured memory map. When I set wrong memory ranges for e1 framer (or other device I don't remember, but error in ranges anyway) this thing prints errors over and over again at the boot time (by u-boot or even linux yet?). I remember there were words: MSR, call backtrace, GPR regs and so on.

Hey, gleb.itech,

  Sorry for late.

  I fix it by turn off an error external interrupt in somewhere...

  So, you are mostly approached the problem.

  Thank you dude!
