22. v3 10A rt version mismatches like this will occur whenever Salvo users and the Salvo for Atmel AVR and MegaAVR distribution are at substantially different versions of the IAR AVR C compiler Therefore we strongly recommend that Salvo users keep their IAR AVR C compiler up to date to avoid any potential difficulties Salvo Pro users can avoid any potential problems by simply re building the Salvo libraries with their own version of the IAR AVR C compiler This type of linker error will not happen with source code builds e g when using Salvo Pro to build an application using the Salvo source files as project nodes instead of linking to a Salvo library Application Crashes After Changing Processor Type Example Projects Remember to include the appropriate header file for your AVR variant see Building the Project above A common cause for such crashes is a difference in interrupt vector locations or definitions between two members of a processor family Mainline code may work correctly but the application will crash if interrupt vectors are not in the right locations Example projects for IAR s AVR C compiler can be found in the salvo tut tul 6 sysac directories The include path for each of these projects includes salvo tut tul sysac and each project defines the sysac symbol Complete Salvo Lite library build projects are contained in the project files salvo tut tul 6 sysac tul 6lite These projects also define the MAKE
