For completeness incase others experience this problem. I upgraded to 8.33 and certain that this solved the problem. In debug settings I have the following options checked. Use Prog Exec if available and Set VDD voltage to 3.5V I also ignore the "Can not enter debug" message which i believe just indicates that the option "Run after successful build" option is not set. 2009/7/3 Justin Richards > Hi Folks, > > I have successfully built my C code for the target OLIMEX_MAXI_WEB but I am > having problems with programming and debugging via the MPLABv8.20 IDE. > > I understand that some devices are not supported directly by the IDE using > PicKit2 but I have checked the list and it indicated that the 18F97J60 is > supported directly for both debugging and programing. > > I can successfully program the target using the PicKit2 software but fails > when I try it from the IDE. > > The error I get is PK2Error0027 (verify failed).
