    is this typo (define loader user 1) in your code or only here, it should read :
    Code:
    DEFINE LOADER_USED 1 ' Comment out if not using boot-loader
    no?
    Also make sure your config fuses are set correctly and check the connections to your crystal.

    Default Somewhat off topic

    I've noticed in several posts, some by the big guns also, the use of lower case when doing a DEFINE.
    The manual says all DEFINEs must be in upper case.(DEFINE OSC 20)
    I've had programs not run because of this (DEFINE osc 20) but also had some run with the lower case DEFINE.

    Is this a mandatory rule or just hit or miss?

    Just curious..
    "It will never happen here!" just happened here.

    It depends on the assembler you are using.

    MPASM is case sensitive by default, and must have uppercase in the define's. (unless case sensitivity is turned off)

    PM is not case sensitive, so it can take either upper or lower.

    But since you don't know what other people are using, anything posted on the forum should be uppercase. (just a request)
