hi , i have read the article of how to use micro tvm at embedded board , the link is at below: https://tvm.apache.org/docs/how_to/work_with_microtvm/micro_ethosu.html#sphx-glr-how-to-work-with-microtvm-micro-ethosu-py
now , if i want to do some experiment at the board , i need to buy the hardware . so where to buy it ? for learning , where to buy Arm(R) Cortex(R)-M55 CPU and Ethos™-U55 NPU.
i am not using Fixed Virtual Platform (FVP) , i want a real hardware.
