Flash programming problem

marius langa

I've finished debugging my program in RAM memory with keil monitor166 and everything works perfect,now I am trying to run it from flash. It writes into flash well, but when I am trying to start executing the program is executing just a part of my program do you have an idea about this problem, how can i configure my flash memory so that my program will work fine?

    You forgot to post any information, so how will anyone be able to help?

    What was the working RAM settings?
    What is the failing flash settings?
    What does the map file look like?
    Where does the application fail?
    How do you know the flash writing is ok?
    What have you done to try to figure out the problem?
    Will a smaller application work?
    Does it matter if you use interrupts?
    What tool versions do you use?
    Which specific chip?
    Anything special with your hardware?

    I use the 6.18 version of compiler and i use timer interrupts and asyncron interrupt, yes for smaller programs it works fine.

    I use the application to create a pwm signal and it crash after the first blink of my led control.

    I've tried to change the adresses from user classes and i've also tried to check the "use memory layout from target dialog" but still doesn't work.

    I use a c163 16F-25F.

    I hope these pieces of information will help you to give me an answer because i'm really new in this and i can't figure out the problem.

    thank you very much
