Reflash of Mitsubshi Evo 6.5 TME - unable to erase flash mem

Postby bing » Thu Sep 04, 2008 11:31 pm

Hello,

I successfully downloaded the flash from my TME 6.5 however when I went to write to the ecu (two test mode connectors in place) I got the following log ...

Can anyone share any insight as to where I have gone wrong ?

Only Evo 7 onwards ECU's can be reflashed. Most of us 6 owners install a 7 ECU. Check out Evo M forums for details.

Please check it out, is the MCU the MH7203F or MH7202F ?

I'm a novice, but what are some possible reasons for the flash memory to not be able to be erased?

The page that failed to erase is the only area with a change. It is my understanding that ecuflash compairs the rom images and only erases/flashes areas with changes.

I really don't understand this stuff, but I read section 16 of the hardware manual H8_538F_HWM.PDF. It explains a lot about the flash memory of the chip. There is even some sample code on how to initiate a flash.

I can only imagine that some of this stuff is pertinent to what is happening here. I found it in the h8/539f datasheet. Can someone with a little experience please comment or give some insight. I haven't programmed since I took basic in HS about 14 years ago.
