[Yaffs] Error during tests

Hello,

This is the output that I get when I try to start the tests in /direct/test:


# ./launch_tests.sh
++ pwd
+ LAUNCHDIR=/mnt/nfs/mcesaran/test/yaffs2/direct/tests
+ RUNDIR=/prova/tmp
+ mkdir /prova/tmp
+ mount -t tmpfs none /prova/tmp
+ chmod a+wr /prova/tmp
+ /mnt/nfs/mcesaran/test/yaffs2/direct/tests/manage_nand_test.sh 0

Mount complete

Integrity error 145

(then the test stops): how can I do?

Thanks,
