Nymand Posted March 23, 2021 Report Share Posted March 23, 2021 I am trying to update to firmware of my old N350+ PnP ECU (G4+). I am using PCLink G4+. Current ECU firmware is 5.6.5.3389 When i run the firmware update i get an error message "Backing up basemap failed." Then the screen freezes for 30-60 seconds, then a pop-up appear with the error mesage: At no point does the progress bar start moving. I have tried changing the com-port, was COM15, is now COM2. I have tried running PCLink G4+ as administrator. I have tried PCLink g4+ ver. 5.6.8 and 5.6.6 (to try one "step" at a time) I think i am out of ideas, of what to do next.

Adamw Posted March 23, 2021 Report Share Posted March 23, 2021 Have you got a dash or other CAN or serial device plugged into the CAN port? Quote Link to comment Share on other sites More sharing options...
Nymand Posted March 24, 2021 Author Report Share Posted March 24, 2021 Yes, I have a aim mxl pista wired to CAN 1. I have to update firmware to >5.6.6 for the Aim protocol to work right? Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 24, 2021 Report Share Posted March 24, 2021 Unplug the dash cable from the CAN port on the ecu, it sounds like you have the wrong type of cable connected which also has wires connected to the rs232 pins. Quote Link to comment Share on other sites More sharing options...
Nymand Posted March 24, 2021 Author Report Share Posted March 24, 2021 I have both genuine link ECU cables: can to PCB cable, and a can to dash cable. I use a CUSB cable for PCLink to computer connection. I will try unplugging the days from the can line and try again. Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 24, 2021 Report Share Posted March 24, 2021 2 hours ago, Nymand said: and a can to dash cable. The CANDASH cable is the problem, despite its name it is actually designed for our old Displaylink dash which used both serial and CAN. So it has wires connected to the serial pins inside. 2 hours ago, Nymand said: I will try unplugging the days from the can line and try again. No, you need to unplug the cable from the ECU. It is the cable causing the problem, not the dash. The other thing you can do to solve the problem if you dont want to unplug the cable everytime you want to connect a laptop is to snip the brown and yellow wires on the CANPCB inside the ecu case. Only the white and green are used. It is the brown and yellow causing the issue. Quote Link to comment Share on other sites More sharing options...
Nymand Posted March 25, 2021 Author Report Share Posted March 25, 2021 Okay thank you, I will try disconnecting the CANPCB from the PCB, and then update the firmware. Quote Link to comment Share on other sites More sharing options...
Nymand Posted April 1, 2021 Author Report Share Posted April 1, 2021 Thanks you for the support, my ECU is now up to date Quote Link to comment Share on other sites More sharing options...
cmj Posted April 1, 2021 Report Share Posted April 1, 2021 I am having this same problem with my G4+ Fury. Using the CAN Cable. Could this also be the same issue @Adamw? If so, what is the best way to resolve for a wire in ECU? Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 2, 2021 Report Share Posted April 2, 2021 The wire in ecus have basically the same cable inside, just a shorter length. You can de-pin or snip the tx/rx wires. Quote Link to comment Share on other sites More sharing options...
