!ERROR 170! Target failed to terminate bus cycle: 000000000@sd word read
!STATUS 170! Emulator terminated hung bus cycle: 000000000@sd word read
!ERROR 702! Emulation memory access failed
To effectively use emulation memory, the monitor must be able to read and write to
it. Read and write accesses to emulation memory are seen by the target system.
Emulation memory will not be able to be loaded if it is interlocked and the target
system asserts bus error on write cycles or does not terminate the cycle.
!ERROR 170! Target bus error: 0000badad@sd
!ERROR 702! Emulation memory access failed
If the memory is write-protected by the MMU, the monitor will temporarily disable
this protection to complete the write. This applies to both emulation memory and
target memory. Once emulation memory is mapped, it can be tested by performing
accesses from the monitor.
If the MMU is turned on and there are no address translations for the requested
emulation memory access, you will see the following error message:
!ERROR 170! Address translation error; non-resident page: 000f84000@sd
!ERROR 702! Emulation memory access failed
