Hello, I am using a P89c51rd2 based board .I have installed FlashMon on the microcontroller and I am trying to use the Keil software to develop small applications. I can connect to the monitor on my board and type commands like memset, but when trying to load the application it disconnects. While trying to find a solution I found that the memory model of this microcontroller is not compatible with FlashMon, and this because the Philips microcontroler needs to erase every block before writing it. Is this true? And if it is can I use an external Ram to load and debug applications on it?
