Hi,
In Redboot ARM e7t, is the console prompt (serial port)
is interrupt driven ?
I mean, when I enter a command, How excatly the
characters are read ? Through ISR or through Polling ?
Thanks
Vinayak

All I/O in RedBoot is polled. Timeouts are used to allow for
some asynchronous behaviour.
eCos applications support full interrupt driven I/O.
