AVR - Atmega328p Dump issue

[paxtonix]

Hi guys , having problems over dumping Atmega328p nano

Using avrdude for it but I don't get nothing back form nano

I checked everything / different programmers , cables, mcu drivers - all gives nothing

even reading out fuses don;t get me nowhere

Code: Select all

avrdude.exe: stk500v2_ReceiveMessage(): timeout
avrdude.exe: stk500v2_ReceiveMessage(): timeout
avrdude.exe: stk500v2_ReceiveMessage(): timeout
avrdude.exe: stk500v2_ReceiveMessage(): timeout

from specs i read that mcu might be BIT 0 ( read protected ) - and I believe it is . Any tips how to dump - or it cannot be done ?

Best

Tried also to establish connection but also no answer from module

pytty , tera term, nothing worked

If your trying to read a gateway they are read protected ..

already know that - alternative way for it ? hex dump will land here one way or another - for all of us to explore- just need to read it out first .

maybe can use any glitch to read avr...like voltage glitch...or clock glitch

here is somthing for atmega328

but you not think its easier ti look wich can messages will send and on wich can messages it will give reaction...and write your own code....i dont thin thats a big deal...when my cangatway arrives i will try...

That’s the way I would do it ,,.

must arriver between tomorow and wendsday....i hope

Sorry, I completely forgot about it - just because I was stubborn to read the hex dump - I forgot to share the CAN dump - my bad

Can_bus_monitor_MS_.log

Can_bus_monitor_HS_.log

Can_bus_logger_full60sek.log

I did for all HS / MS lines with a time bar. Also during the bench test, I noticed that some Can messages were not coming when the engine was off. - In my test environment, I only have bcm and IPC without ECU. may be the reason I missed the CAN message

LOG's Are to big to post direct on forum

better do a hs-can and ms-can trace while you drive...
deactivte auto pam while driving...
after do a trace ms/hs-can with activated auto pam while drive....
so you can find better the can ids when you compare them
