Trouble with AT89C51ED2

sam chakssam

i have bought a mini-board that has an ICP connection and was trying to program it using keil uvision3. since i use my laptop, i had to interface the USB with RS232, so i used USB to DB9 serial port. First question, i am not sure if the keil would recognize the target board mentioned below through this USB adapter. the second question is for this kind of programming what kind of configuration (flash configuration) in keil software i should use ? what is ULINK ?

kindest regards

    USB to serials generally DO NOT WORK for program development tools, but many posts have stated the few such devices available that are based on the FTDI chip DO work. Unfortunately, not many manufacturers list which chip is inside.

    at the flash magic forum they are in the process of compiling a list of brands that work and brands that do not.

    "i have bought a mini-board"

    What "mini-board"?

    "that has an ICP connection"

    What sort of "ICP connection" does it have?
    Is it intended to work with a standard PC COM: port?
    Is it supported by Keil, or any of the utilities that Keil support (eg, FlashMagic)?

    "i am not sure if the keil would recognize the target board mentioned below"

    You didn't mention any target board "below", and you didn't give any details "above" - so how can anyone tell?!

    "what kind of configuration (flash configuration) in keil software i should use ?"

    Again, you haven't given sufficient information to answer this, other than to say read the Manual for the board, and do whatever it tells you!

    "what is ULINK ?"

    This is it: http://www.keil.com/ulink/

    thank you for the response

    I thought i posted the link of where i bought the min-board. my first goal right now is to get short c program into the flash of the AT8951ED2. but i am having a hard time getting the software to recognize that there is a programmer at the serial post.
