Overview
Description
The Renesas RA6M3 group of microcontrollers (MCUs) uses the high-performance Arm® Cortex®-M4 core and offers a TFT controller with 2D accelerator and JPEG decoder. Additionally, the RA6M3 MCU offers Ethernet MAC with individual DMA and USB high-speed interface to ensure high data throughput. The RA6M3 MCU is built on a highly efficient 40nm process and is supported by an open and flexible ecosystem concept—the Flexible Software Package (FSP), built on FreeRTOS—and is expandable to use other RTOSes and middleware. The RA6M3 is suitable for IoT applications requiring TFT, Ethernet, security, large embedded RAM, and USB High Speed (HS).

Renesas RA6M3 Ethernet's SMI does not have output.
Hi all, I encounter a problem. As the title says, my ethernet controller does not output any signal from SMI. My fsp is v2.2.0. My ethernet PHY is DP83826E. Who can point me to what happened now, please? I measured the REFCLK_50, it has output from ETHERNET ...

EK-RA6M3 debug, Live Trace Console: preventing "itm_trace_*" tabs
I'm debugging on the EK_RA6M3 board. I've enabled printf() semihosting output to the Live Trace Console, including enabling ITM Stimulus Port 0. This works fine. When I hit a breakpoint after debug output is generated, e2Studio creates a tab called "itm_trace_*" (the final part is a ...

ERROR: readResponsefromServer() function failed.(error 0x30038) Http implementation using Azure RTOS (Evaluation Board: ek_ra6m3)
I am trying to connect to my server using Azure RTOS. I have successfully initialized ip address and have created http client. The code works fine until nx_web_http_client_request_initialize() but stucks at nx_web_http_client_response_body_get API while reading response from the server.

RA6M1, RA6M2, RA6M3, RA6T1, RA6M4, RA6M5, RA4M2, RA4M3: Can A/D conversion be performed on other analog input?
Yes. Temperature sensor output and internal reference voltage are selectable at the same time as the analog input of the channel. A/D conversion is performed first for the analog input of the channel, next for the temperature sensor output, and then for the internal reference voltage.
