Another thing, (gee, sounds like I whine a lot :-), could the next batch have socketed CPU chips?
How much would that add to the cost?
This would allow further changes to the CPU, (include newer extensions like the Vector instructions), with just a CPU upgrade to the base board.
If done, their should be provisions for extra pins. For example, later boards might have more PCIe lanes. Or allow ECC memory. In essence what would be happening is establishing a standard RISC-V CPU socket. De-couple the CPU from the board, allowing both to grow and change specific to a user’s want & need… Similar to what Intel and AMD do.
