Title: ME 7.8 Boot Mode MiniMon - Need Help
Post by: jrosen on September 24, 2017, 05:01:49 PM

Hi Guys,

I'm struggling to get minimon working with a Porsche ME7.8. I'm working on the bench, and I'm able to get the ECU into boot mode and minimon shows "CONNECTED AND READY", but no matter what range of addresses I try and upload it doesn't work. Minimon gives the message "Error: no data received" and then the status bar shows "NOT CONNECTED". Any help would be appreciated.

Below is the log output from MiniMon and I have also attached my minimon preferences file.

Code:

*Loader file Prepare
*Minimon file Prepare
*send Byte  0+ Loader + MinimonCore
*RECEIVE - MC-Identifier: D5
*RECEIVE - LoaderACK 01 received
*RECEIVE - Minimon ACK 03 received

Just to be clear, by "upload" I me read from the micro/flash to Minimon.

Also, does anyone know where I can find a minimon driver for 95320 eeprom?

Thanks

Some success - I was able to download the flash. The issue I was having was due to the EINIT command set in the target configuration and also, some incorrect register initialization values. I have attached the minimon preferences file that worked.

I think the data that I'm really after is in the 95320 eeprom, but I'll see what I can find in flash. It seems like a driver for the eeprom is a dead end.

For me the script resulted in:

Code:

*Loader file Prepare
*Minimon file Prepare
*send 0 Byte + Loader + MinimonCore
*RECEIVE - MC-Identifier: 85
*ERROR: No Loader_ACK Byte received (MinimonCore not loaded)
*ERROR: No Minimon Byte received (Minimon not successful)

There is another script in here. I adapted that and got it running for ME7.1 .
Ensure that initial command calls (here EINIT) are deactivated, select the right port for your interface and go for it.
