Hi Pro,

 

I'm trying to use UART to communicate between my computer and KL05Z (Rev B1) by using PE as this tutorial

 

http://mcuoneclipse.com/2012/10/14/tutorial-printf-and-hello-world-with-the-freedom-kl25z-board/

 

I have the problem is i don't know which pins UART of KL05Z32M is used to connect to open SDA.

 

On the schematic http://cache.freescale.com/files/soft_dev_tools/hardware_tools/schematics/FRDM-KL05Z_SCH.pdf?&Parent_nodeId=&Parent_page… shows two pairs UART0 (Pin No 17, 18 ; Pin 23,24 sheet 3 of 5). But in sheet 4 of 5 shows UART1_TX_TGTMCU and UART1_RX_TGTMCU ( on Target MCU KL05Z32M , I think) are connected to OpenSDA.

 

My question is which pins UART of MCU KL05z32 is connected to OpenSDA ?

 

Please help me on this issue.

 

Thank you.

Minh
