Bus Error Dumps
Continuing the example, the following analysis finds the offset within a product module.
Since the address that caused the exception is 0x0063cb1a, the SWAN Kernel
(T7848) is not the cause because the SWAN Kernel usually occupies addresses from
0x400000 to 0x490000 and is static. The start address of DLC0 or DLC1 or DIAG can
be found from the SWAN control-table display.
