Re: [ECOS] ecos application problem

["albert prasetyo" <prasetyoalbert@gmail.com>]

Hi Sergey;
Thank you for your info. 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.

Regards;
Albert P
