That's what i will try after dumpig micom EEPROM now.
But i'm a bit afraid of changing UART bit, because of loosing my only remaining way into the tv :/
Why not directly try to change the watchdog bit at 0x6D51 to 0x00?

Re: C Series EEPROM research
don't worry, just do it. debug - uart - debug is only byte which let us know we are on right way. Of something wrong, you can set that byte back, you have dirrect write access to eeprom, why scared?
but sure you can just change that watchdog byte.

Re: C Series EEPROM research
Guess you are right again! Got bit 0x6D51 set to 0x00, but had no effect, even after power reset.
So i will try to follow your advise and change micom EEPROM.
EDIT: Changing micom EEPROM part (which worked!) can be found here: viewtopic.php?f=15&t=7133#p53883
I think we can start researching on monday. Just advise me whoch settings (and where) to check.
Can i you figure out the addresses in one tv session (change setting in service menu and then dump the micom EEPROM, change back, dump and compare)?

Re: C Series EEPROM research
Yes, in most cases here was no need to reboot TV. value in eeprom was changed immediately. Most interesting values are rs232, watchdog, OTN on/off and so on, it is up to youhedak wrote:Can i you figure out the addresses in one tv session (change setting in service menu and then dump the micom EEPROM, change back, dump and compare)?
i wonder what if EPG data are stored in eeprom, possible?

Re: C Series EEPROM research
The problem is that i don't know the service menu setting. I even had to google for OTN's meaning But i will do at least the ones you mentioned What about micom EEPROM? I will dump effect of SW toggle for example.
Any idea how to check for EPG data in SoC EEPROM? Just comparing two dumps will not be sufficient i think as it's not ASCII (IIRC from 'reading' all my EEPROM dumps).

Re: C Series EEPROM research
i think it is unlikely to find epg stuff in eeprom..
-epg empty at every boot
-various amount of data
-many changes during runtime (especially when filling)
this smells more like tmpfs...

Re: C Series EEPROM research
As i found out during my unbrick procedure my SoC EEPROM content was static after every boot. Maybe because i unplugged cable wire. Furthermore i have FastStart feature (ATM disabled) which (i read) keeps data available for about one day. That could help to figure it out a bit easier.
BTW i'm coding an I2C sniffer for my teensy++ 2.0 board ATM to see what's going on there I will check it's operation at work tomorrow.
