Hi All,
I am new to Uboot, I am trying to port Uboot on 8308, on single steeping the uboot gets stuck at _start_of_vectors_ Machine check exception. Could anyone please explain what STD_EXCEPTION mean in start.S code and why it happens ? Following are some logs BDI8308_ELAN06>ti Target CPU : MPC83xx (e300c3) Target state : debug mode Debug entry cause : instruction address breakpoint Current PC : 0xfff0017c Current CR : 0x20000000 Current MSR : 0x00003072 Current LR : 0xfff00168 BDI8308_ELAN06>ti Target CPU : MPC83xx (e300c3) Target state : debug mode Debug entry cause : COP halt Current PC : 0xfff00220 Current CR : 0xe6000efc Current MSR : 0xe6000efc Current LR : 0xe6000efc # Step timeout detected The address 0xfff00220 corresponds to Machine check exception in System.map of u-boot code.
Thanks Sharath
