RW612-GPIO Pin Conflicts

[wima88]

Hello,

While running the SCTimer example, I noticed some duplicated GPIOs in the quick start guide:

Connector Pin # GPIO #

J2	4	52
J4	5	52
J5	4	3
J1	3	3

It appears that for the example, J5 pin 4 should correctly correspond to GPIO 3. Is there a resource where I can find the accurate pinout information?

They are not conflicted -- one is for GPIO_2_FC0_I2S_DATA and the other is for GPIO_2_FC0_UART_RXD_ME, as shown in the FRDM-RW612-SCH.pdf. Thanks to your post, I spotted the difference. I've spent almost a week trying to figure out why my usart had no output...

Yes

Hi,

Are you using the FRDM-RW612?
