you didnt post the full build log. you didnt include the actual error message in the output.
run `make single` to force the build to abort on an error.

SMP is not supposed to work on bf561 rev0.3 due to hardware anomalies. You may try bf561 rev0.5.

what anomalies ? there are no checks in the kernel for 0.3+SMP that cause a failure.

Anomally 248 said,
BF561 0.3: When one core performs a testset operation to L2 memory it locks out the other core if it is accessing L2 memory.
Workaround:
Any TESTSET operation to internal L2 memory should be followed immediately by a (dummy) write to L2 memory.
CLI R0;
NOP; NOP;
TESTSET(P0);
W[P1] = R0; // P1 Points to L2 Memory
STI R0;
But the dummy write which following testest will cause infinity stall.
There is a task,

if the workaround documented in the anomaly text isnt working, then you should raise the issue with the ADI apps team
