It provides me further understanding on how redboot and ecos work. Actually, my board (AT91RM9200) is designed to communicate through PC using 1 serial port only (DBGU port). Is there any way to print "Hello World" (i.e. Application message) using only one port? Moreover, my board does not have spare LED, the LEDs are only used to signal whether the board is turned on or not and Ethernet connection. Thank you for your attention.
