On bf548 ezkit and bf518f-ezkit, there is one more fail test 21. It is not found

failing on other boards.

 

Running test 19 for exception 0x00: prefetch l1_dataB^M

... PASS (test completed 1/1 times, as expected by signal 0: Unknown signal

0)^M

^M

Running test 20 for exception 0x00: prefetch l1_instruction^M

... FAIL (test exited sucessfully, and we expected 4 Illegal instruction

failure^M

FAIL (test completed properly 0/1 times)^M

^M

Running test 21 for exception 0x00: prefetch _l1_non^M

... FAIL (test failed, but not with the right signal)^M

        (We expected 0 'Unknown signal 0' but instead we got 11 'Segmentation

fault')^M

FAIL (test completed properly 0/1 times)^M

^M

It is strange that when the testing target board is switching to bf527 ezkit 0.2

on Sep 22, case 21 also fails. While this case used to be passed on bf527 ezkit

0.0.

 

Running test 21 for exception 0x00: prefetch _l1_non^M

... FAIL (test failed, but not with the right signal)^M

        (We expected 0 'Unknown signal 0' but instead we got 11 'Segmentation

fault')^M

FAIL (test completed properly 0/1 times)^M

 

The revision changes are:

failed revision: uclinux-dist   8880   linux 7402

passed revision: uclinux-dist   8871    linux 7391

 

Follow-ups

As we changes the toolchain from 09r1-10 4.1 toolchain to svn trunk head 4.3

toolchain (svn-3679), this case also fails when built into fdpic format.

As mentioned in bug 5468, Vivi please help to disable the prefetch tests in

traps tests.

Traps test is passed now.

So close it.
