Ok found how to generate a MAP file in MPLAB version 7 Under Project>Build Options>Project>MPLINK linker Tab and tick Generate map file. Thanks. _______________________________________ Roy Tauranga New Zealand _______________________________________ What you should look in, is the MAP file. Note that you have to explicit say that you want to MAP file in the MPLAB config (or on the MPLINK command line, if run outside of MPLAB). Everyone using the linker *should* enable the MAP fil, IMHO. It would have been better if MPLAB could have checked the "MAP-file" checkbox whenever one adds a linker script to the project... -- No virus found in this outgoing message.
