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... 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.

Hello:
According to the schematics, in FRDM-KL05Z the OpenSDA interface is connected to the target MCU (KL05Z32) by the pins 17 and 18 (PTB1 and PTB2). This is also mentioned in the FRDM-KL05 User Manual, in two sections:
Hope this helps!
