This test can run now. But I can see it fails at test 18 and 29.

Bellow is the log for test 18:

Running test 18 for exception 0x23: Illegal use of supervisor resource - MMR

Write

... Unrecoverable event

- For example, an exception generated while processing a previous exception.

traps_test can pass all on bf527-ezkit 0.0 board, and can pass until case 48 on

bf561 ezkit.

while on most bf537 and bf533 boards, the case fails at case 18 and stops.

--- Robin Getz 2009-06-08 21:26:48

Kernel bug - fixed on trunk and branch. (Yeah - that is what we run this test

for!)

We don't need to handle CPLB protection violations unless we are running

with the MPU on. Fix the entry code to call common trap_c, and remove

the nompu code which is never run.

--- Mingquan Pan 2009-06-16 06:05:40

Yes, it fixed on almost all the boards we testing, BF537 STAMP,BF527 and BF548

ezkit, bf561 ezkit and bf526 and bf518 ezbrd.

But it looks it still have some problem for BF533 STAMP board at case 32.

Running test 32 for exception 0x2b: Jump to L1 Data A

... CPLB protection violation

- Illegal instruction fetch access (memory protection violation).

I verified this does happen on 533 (0.3) silicon, but not on 0.5 silicon.

Can you confirm that 0.5 silicon works as expected?

-Robin

--- Vivi Li 2009-06-30 03:25:24

We only have BF533-STAMP board with 0.3 silicon.

In BF533-EZKIT board with 0.4 silicon, this test pass.

--- Robin Getz 2009-07-09 12:08:33

I put something into trunk which should fix this.

Since I don't have a 533 anymore (it's in a box, while I move offices), I can't

test it -- if You can test trunk, and let me know if it works - I will put on

the branch tomorrow.

-Robin

--- Mingquan Pan 2009-07-13 00:01:30

Yes, I see this trap case pass all cases on bf533-stamp(0.3). So close now.
