UART Example Problem when changing pins

[TK Here]

Using the UART example of the 52DK with the TX and RX pins set as 8 and 6 the example works.  If I try to change the pins to different pins such as 22 and 23, it does not work by giving an UART Comm Error.  Problem is reported from the UART ISR.

I am using uart_pca10040.  I do not see where pins 22 and 23 are being used.  Can you be more specific?

That sounds strange. I tried using pins 22/23 and I don't have any problems.

Are you using the ble_peripheral/ble_app_uart or the peripheral/uart example? And which SDK version?

I changed to IAR and works fine.  So I am good.  Thanks for the support from everyone.

I'm glad you were able to "solve" the issue.

Could you tell me which IDE you were using when you got the error?

Cheers.

I was using Keil.
