EPM900 4K limit not making sense

Alex Burton

Hi,

I bought a EMP900 thinking I was getting a programmer and emulator that was not crippled.
I understood that there was an evaluation version of some c compiler that I could look at.
Now I am finding that the only way to use the EPM900 is though the IDE which is limited to 4K.

I am actually using another compiler so I don't want to buy the uVision tools.

I have been using the hex file output of my compiler to program the emulator.

Now I am finding that with only 2K of code the software is saying that I have 8K of data, which is over the limit of 4K.
It's only 2K - I can see in the hex file.

Can anyone help me ? I just want to be able to use the product I bought.

    To understand that the product I bought was limited by the evaluation version of the IDE it comes with would require quite a few logical assumptions on my part, being new to Kiels 8051 toolchain.

    The EPM900 you bought costs around $400, the CA51 compiler kit costs over $1000 (and the PK51 even more). That alone should ring some warning bells.

    Emulator requires uVision studio to work would be the main one.

    That is clearly stated in the manual, which is available for download on this web site:

    http://www.keil.com/support/man/docs/epm900/epm900_in_swreq.htm

    To compile, link and run applications on the EPM900 Emulator Board, you must install these Keil products:

* The LPC900 Development Studio, which includes the uVision Debugger.

    The limitations of the LPC900 Development Studio are explained here:

    And as always, if you have questions and want answers from actual Keil employees, you need to use contact their tech support. Posting messages here in this forum is not likely to get you a response from Keil staff (it might happen, but don't count on it).

    I am not inclined to purchase any more kiel products however.

    I do not think that you will be completely happy with any other companys products if you do not read the product description and ask questions if any points are unclear or if you need to confirm that the product fits your requirements.
