MPC8544 bootloader keep printing debug message over and over

duckycool — Wed, 05 Aug 2009 19:31:14 GMT

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?

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!
