Hi,

I'm testing connection with demo board,I found an option-"Access Port Designator" in target configuration,what does it mean?And why is it set to 0x02000100?

Thanks.

This is related to the debug subsystem that is on the device. This device is configured such that the Cortex R core is at that address on the debug access port. The address and designator values should not be changed.

Basically the access port designator is just a way for the driver to know what AP number is used for the AHB and the APB.

Regards,

John

Hi John,

Thank you for your reply,does it mean the value of address 0x80001000 is 0x02000100?When CCS reads a value of 0x02000100,will it connect to the demo board?

I am not an expert on it but I believe the address on the bus for the R4 is 0x80001000 and the ID is 0x02000100. I am not sure where the ID is stored.

So what are the address and id used for?

The debug software has to know this informaiton to be able to access the components on the device.
