This is a chip that I have been excited about for a while since they are highlighting the open source tool support including the SoC and FPGA emulation with RENODE.
Zephyr is the highlighted RTOS, but I thought it would be a great candidate for NuttX, especially since the MCU is a ARM M4 so the initial porting should not be too bad. I have a couple on the way, and thought others might be interested. https://www.quicklogic.com/products/eos-s3/quickfeather-development-kit/ https://www.quicklogic.com/software/qorc-mcu-efpga-fpga-open-source-tools/ --Brennan
