Hi there,

./include/configs/at91rm9200dk.h says

/*
* select serial console configuration
*/
#define CONFIG_SERIAL3 1 /* we use SERIAL 3 */
#undef CONFIG_HWFLOW /* don't include RTS/CTS ...

My question is:

Is "SERIAL 3" the same as the so called "SERIAL DEBUG PORT" in the RM92000DK schematics?

If not, what's the purpose of the "SERIAL DEBUG PORT" ???

Thanks a million,

Steven

Hi Steven,

The serial configuration flag CONFIG_SERIAL3 is useless for the AT91RM9200DK board. It is only used by the smdk boards. It should have been removed from the configuration file.

The AT91RM9200 U-Boot version uses effectively the Serial Debug Port.

We are going to submit a patch correcting that mistake among other things and adding DataFlash support.

I hope this helps.

Nicolas.

That means that I can use the "Serial Debug Port" as a console for U-Boot and Linux!?

Thanks a million!
