hi, I am using MCBx51 Evaluation board. I have problems for programming Atmel T89C51RD2 in ISP mode with RS232. I had made all modification on the board which is given in the link below http://www.keil.com/appnotes/docs/apnt_156.asp i) I am using Atmel T89C51RD2 microcontroller with 12 Mhz clock frequency. ii) baud rate is 19200 ( 12*1600) as per baud rate calculations. I am not able to select communication port (ie, RS232) in FLIP S/W, after selection of RS232 and baud rate (19200) that software gave Flip2 message "Time Out error". Do i need to change or give any other settings in board or keil uvision2? Please send me solution as early as possible. Thank You. krishna.
