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.
Hi Krishna, I'm not familiar with the hardware setup of your board. But, it is possible that you must reset the board while trying to connect with the Flip software. I had the same problem once. Worth trying out :) Regards John
