Is it possible to set the window to use an external source? As I have a USB to Serial adapter connected to my debug unit using a ULINK2. As I want to use this window as my serial output window if possible.
I have a AT91SAM7S128 target so I know I can't use the modern Cortex debug features.
What about the USART#1 window?
You can implement your own hosting code for the STDIO (printf,putchar), and output that to any terminal software. Look in the examples directories for serial.c and retarget.c code for different platforms.
Doesn't the ARM7 have the DCC (Debug Communications Channel)? infocenter.arm.com/.../index.jsp
