Hello,
SWD port of PSoC5LP is assigned to P1[0:1] as an initial setting.
It is described that P15[6:7] is also assigned to the SWD in the data sheet.
Do you know how to change SWD port from P1[0:1] to P15[6:7]?
Perhaps we thnk that would be to rewrite the NVL.
If it is possible to change, is there anything to note about changing?
Even if SWD is set to P15[6:7], is it also possible to assign P15[6:7] to GPIO?
Regards,
Masashi

Have a look at the following conversion of a KitProg to KitProg2.
Convert Kitprog1 into Kitprog2
It discusses using SWD port on P15[6:7].
According to this successful conversion, the 5LP looks at both SWD ports after XRES is toggled, looking for SWD activity.

Bill

Hi Masashi,
The SWD pin has been fixed when the chip out of the factory line, so the customer has no way to change the SWD pin.
But the SWD port pin can be configured as GPIO out of programming mode.
Thanks,

Hi,
Notation such as Port 15[6:7] of SWD is described in various parts of the data sheet.
Does this mean that it was scheduled but not realized?

15[6:7] and 1[0:1] both can be the SWD interface.
But in the factory, we fixed one of them (1[0:1]) as SWD interface.
So we can ignore the other one.

Hi,
Again, We would like to confirm on this matter.
I heard that you are not connected internally.
However, when connecting MiniProg 3 to P15[6:7], it was recognized with SWD without any problem.

Hi,
one of our customers is using 15[6:7] since the beginning of P5 (before to be LP). He has a "special" connector (and cable) USB (as you know, 15[6:7] are USB line also).
Besides the two lines SW (CK and D -15[6:7]-), you need the reset (he connects the reset to the ID pin at USB connector). He uses the Miniprog3, using the 5 pin connector.
Of course, if you are using this method, you can't use the USB.
If I'm not wrong, he has the P1[0:1] configured as GPIO (because he is use them for other purpose)
Regards
Gil
