@Van2Jo, can you please provide more context, more specifically:

• What is the name of the failed test? On which platform did the failure occur?
• How are you running the tests?
• Please, attach verbose logs to the ticket. These can be obtained by passing -d3 flag to OpenOCD. Note that the logs can be quite large.
