Finding the type of fault in Debugging information

## Finding the Type of Fault

The type of fault is the first piece of information that you need. There are two possibilities:

- an unhandled exception has occurred

- a panic has occurred

To start, use the f command. You will see something like this:

Fault Category: Exception Fault Reason: 10000000
ExcId 00000001 CodeAddr f800415c DataAddr 00000000 Extra 00000005
Exc 1 Cpsr=60000013 FAR=00000000 FSR=00000005
R0=64007328 R1=00000000 R2=00000000 R3=00000001
R4=64007328 R5=640074c0 R6=00000000 R7=f8047ba4
R8=64006f80 R9=64006fec R10=00000013 R11=64006ec4
R12=00000001 R13=000029b4 R14=0000016c R15=f800415c
R13Svc=64006ea8 R14Svc=f8002b2c SpsrSvc=600000ff

The Fault Category field shows the type of fault, in this case an exception.
