I was wondering if TinyCLR could be ported to this?
Performance and flexibility
32-bit ARM® Cortex® R4 @ 320MHz for applications29 dedicated GPIO ports, 2 SPI, 4 UART (2-pin), 4 ADC, 1 JTAG, 2 I2C5-12VDC input voltage
Yes it would but this is R4 core, meaning we need to port the library to R4. This is not M4.
