Thanks, I took VCC and GND from board, from the points is this photo...

Hi guys, not having much luck with a USB TTL UART, with everything setup, when I ground the reset all I get is a little random data in the terminal window. Entering #00 or 00 in the top "send" box and clicking send, nothing happens. I have rechecked all my connections and even tried revers...

Thanks vtl, so to clarify.... Add this to the M16C config file [Controller] Name=M32C@0xFC0000 Group=Generic BaseAdr=FC0000 Blocks=1 From=FC0000 Size=40000 [end] This will enable you to choose M32C@0xFC0000 from the controller menu 1. Connect USB<>TTL adapter (4 wires) to TX,RX,GND,+5v (VCC) 2. Powe...

I have tried searching, Is this what I am looking for? https://www.matthewsvolvosite.com/forums/viewtopic.php?p=572965#p572965 ***** When you have P2 on bench, connect pin 8 to +12V and pin 15 to +12V, this makes CEM stay in lock pos 1 and doesn't fall asleep, guess you need to find the same pins in...

Thanks vtl, like this? https://www.ebay.co.uk/itm/262285972686?hash=item3d117654ce:g:aeMAAOSwj5Rgzklg I can't see where CNVss and BUSY would connect to the adapter? Regarding the eeprom, I can read it and have done already but all I want to do is install a donor CEM from another car, If I just blank...

Can someone confirm that with the following R0E00008AKCE00 Renesas programmer that I can indeed read and write the flash of the M32C MCU on the 'L' shaped CEM from a 2005 XC70? https://uk.farnell.com/productimages/standard/en_GB/GE1172316-40.jpg If the answer is yes, would I use the connections show...

I have the eeprom dumps already as I tried to fill the eeprom on the replacement CEM with FF and resoldered to the CEM in the hope that VIDA would think the CEM was new but no go.... So with IOTerminal and the eeprom dump do I need CEM cracker at all? Maybe I should be asking IOTerminal but as menti...

Hi Guys, I need to swap an XC70 2005 CEM, i have the original and donor CEM's, I am able to communicate with either in the car with Vida (Genuine with subscription access). Of course I can't do a CEM reload with the donor CEM installed. I am thinking I will use IOTerminal to r/w the original and don...
