Hi All,
I am facing an error while porting u-boot for my platform because if exception error.
After running the u-boot to detect the DDR and flash u-boot hangs after showing the serial console output. In debugger I am seeing PC at 0x00000400 address which the exception handler vector address.
But when I modify the below statement in the function int interrupt_init (void) in u-boot\lib_ppc\interrupts.c, u-boot continues and I can see the u-boot prompt and I am able to run all u-boot commands.
int interrupt_init (void) { int ret;
/* call cpu specific function from $(CPU)/interrupts.c */ ret = interrupt_init_cpu (&decrementer_count);
if (ret) return ret;
set_dec (decrementer_count);
--- set_msr (get_msr () | MSR_EE); //Removed this statement. ++ set_msr (get_msr ());
return (0); }
It seems that there is an exception error and because of this u-boot hangs. But I didn't get any error condition till now.
If someone has earlier experienced this kind of issue, please share.
Regards, Prakash
