My question is: I am going to layout my hardware and bring the serial port out so that the keil debug monitor porgram can run on our owwn hardware. According to the previous discussion, I know that is possible for doing that. My another question is: Does my hardware need to include the PAL and the external RAM which is on the EZ-USB-FX development board? If it is not necessary, how can I relocate the user code so that it loaded into the EZ-USB internal RAM? Thanks
