![]() tsp uses uart2 and is printing some init messages in main, but in certain situations we may exit tsp and may not have flushed uart data, this could later land in uart fifo overflow or random corruption. Time to time we have seen a character corruption on uart2 arising out of logs from tsp main. So flush console messages from tsp_main before leaving the function. This is inline with our uart usage strategy across TF-A as most entry _main function ensures uart console is flushed before exit. The console flush is harmless and should fix the potential character corruption if it was due to tsp_main negligence. But we cannot also rule out that it could be a potential FVP-UART problem, but that's quite unlikely and further CI daily's will give us a idea if this fixes the character corruption seen or we may need stress test FVP-UART which maybe corrupting character in certain circumstances.
