Hi Raymond, great that it works! These CSR ROM devices can be really frustrating. > ( However, It is really strange here, without setting this value, why > hciattach can connect the chip for the first time, while do a warmreset , it > won't ?

They don't have any value set, but guess from the incoming message what is the baud rate. That's why if you look with the scope at signals, you see that chip doesn't reply to the first message from the processor, but needs typically few messages to guess the baud rate.
