ohhh so,this chips are not rp2040?? but they say in the boads,and supliers say they use the same picofly firmwareI don't think I seen anyone try installing rehius fw on Chinese hwfly rp2040 boards. As far as I understand, these models are using completely different closed-off firmware than the one posted in this thread. We do have guides for the non-hwfly boards, which what the rehius firmware in this thread is specifically written for, not hwfly boards.

yes i see the diagram you send me in the another post,hope can test the traces and also use the diagram,BUT then,they are or not picofly rp2040??See that square black chip in the middle of the board? It's an RP2040 System On a Chip. The diagram I sent you is a pinout of the pins coming off that chip.
