Just got the EK-RA4M2. Downloaded example code from here (EK-RA4M2 – Evaluation Kit for RA4M2 MCU Group | Renesas). Connected
1) RXD MISO P410 ——-> TXD Pin of USB-UART
2) TXD MOSI P411 ——-> RXD Pin of USB-UART
3) Common GND
as readme.txt.
However, there is no serial activity. any suggestions?
The pins P410, P411 are connected to the SCI0, and pins P601, P602 are connected to the SCI9. Have you changed the channel number in the UART stack like this? Also make sure that the Rx/Tx pins have both CMOS output type:
