The default ISR (particularly the HardFault handler) print information, but this information was not displayed on the console because the UART IRQ is lower than some default blocking IRQ. Allowing to set synchronous transfer corrects this. The underlying Atmel exception library had to be modified to use the synchronous output. Making UART_PutChar always synchronous when called from an ISR is not desired because we use TRACE_ macros is some ISR. The synchronous output must be set explicitly.
