This platform has a tiny handful of remaining tests that fail. We will track them as issues, but let's exclude them from integration testing to allow full runs to complete. Often a hung device in one test will break an entire twister run. Tests with known (and tracked) failures: samples/application_development/external_lib samples/posix/eventfd samples/userspace/hello_world_user tests/kernel/fatal/message_capture tests/net/socket/socketpair tests/portability/cmsis_rtos_v2 These tests never fail in isolated testing, but are reliable timeouts when run in sequence in a big twister run. It's possible that the bug here may be in twister or the flash/serial scripts: tests/crypto/tinycrypt tests/subsys/logging/log_immediate tests/subsys/logging/log_output See: #32836 Signed-off-by: Andy Ross <andrew.j.ross@intel.com> |
