2008-04-25 00:59:02     uImage download

Message: 54921   

 

Hi,

 

I created an UImage for an embedded hardware which is based on BF561 and I downloaded the same. But while execution I am getting the following error and system restarts.

 

Starting Kernel at = 1000

Code=[0x21], stack frame=0x1f9b9f0, bad PC=0x1fc0130

 

Unhandled IRQ or exceptions!

Can you please help me in this case?

 

The following details are captured on teratem.

 

Best regards,

 

Vijaya

Message: 54922    you should update to 2008R1 as it'll give much more useful debug information

 

you can also try turning off cache before booting the uImage

 

have you actually validated the hardware and memory to make sure it's stable ?
