\nIssue:\n<\/p>\n
\nTrying to debug or program using a ICD3 with MPLAB X gives this error:\n<\/p>\n
\nTarget detected
\nUnable to connect to the target device.\n<\/p>\n
\nCause\n<\/p>\n
\nICD3 has previously been used with MPLAB IPE V3.xx and you are now using IPE or MPLABX V2.xx\n<\/p>\n
\nWe discovered this after using IPE V3.35 and then using MPLABX & IPE V2.15. Solution was to use MPLAB IPE V3.35 to program the device at which point it picked up that the ICD3 had previously been used to program a PIC18 and needed its firmware updating to now be used with the PIC32 we we're programming. So seems V3 is storing some marker in the ICD3 that V2 doesn't understand\n<\/p>\n
\nMicrochip support response\n<\/p>\n
\nMPLABX IDE v2.15 -> Project properties -> "ICD3" -> "Option categories" -> "Firmware" -> uncheck "Use Latest Firmware" -> I selected the .jam file -> then program the device with IDE. After this it worked also with IPE v2.15. \n<\/p>\n
\nSee if "Use Latest Firmware" is checked. This usually make MPLAB X to update the ICD3 firmware with the right software for the MPLAB X version used. As I described above, it can be updated manually. If the ICD3 is not loaded with the software corresponding to MPLAB X v2.15 when going back from MPLAB X v3.35 it is possible that there may be some backwards incompatibility that may cause problems. <\/p>\n","protected":false},"excerpt":{"rendered":"
