RM48L952 SCI problem

Other Parts Discussed in Thread: RM48L952, HALCOGEN

Hi,

I'm working on the RM48L952 HDK board and trying to make a serial communication using RX and TX pins of the board expansion connector.
I can connect through the SCI/LIN port using the Mini USB connector and the example code "example_sci_uart_9600.c", but the communication is not happening through these pins.
The SCI module was configured in HALCoGen, also the SCI pins are multiplexed with N2HET1[06] and N2HET1[13] in PINMUX module.

I would appreciate it if you could help me.

With regards,

Fatemeh

Fatemeh,

I was able to run your code without any modification and I can see transmission on the TX pin located on J11-49. This is the Ball N2 (NHET1[13]/SCITX)
Your code is correctly setting the pin muxing to make the SCI_TX and SCI_RX functional on Ball N2 and W3 respectively.

If you want to use the SCI connected to the USB connector, than you have to use in Halcogen the SCI2 driver. This will use the following pins:

LIN_RX J11-5 Ball A7
LIN_TX J11-6 Ball B7

Please let me know if I've answered your question.
