There are 33 errors when trying to build the RX600_RX64M_RSK_Renesas_e2studio demo. The root cause is a call to the undefined sprintf() function in MessageBufferAMP.c (2 instances) and MessageBufferDemo.c (6 instances).
Commenting these calls out results in a successful build and loading the program onto the RSK+RSK64M development board correctly blinks the LED.

You do not need hardware to reproduce this issue. Simply download the latest E2 studio from Renesas website [Windows only] and import the RX64M demo as described on the FreeRTOS website (https://www.freertos.org/RX64M_RTOS_Renesas_GCC_e2studio.html). The initial build fails.
Work-around (in-progress): In the E2 Studio IDE, select Project > Properties > Standard Library > Contents and then check the box marked “stdio.h”. This resolves the 2 sprintf linker errors, but does not resolve other 31 linker errors such as "Description Resource Path Location Type
