[howto] Switch boot partitions via micom eeprom C series
Re: C Series EEPROM research
OK, thank you! Micom EEPROM has 256 byte (or 2kBit ). Will dump and upload tomorrow
Re: C Series EEPROM research
So, here's my micom's EEPROM dump. It's the same in standby and powered on.

Re: C Series EEPROM research
heyyy. your eeprom just looks like i have suggested to user to change bytes in eeprom topic.
in your case you have to set it vice versa

Re: C Series EEPROM research
jup, but i want to disable the watchdog first
But i'm failing right now... Executing 'http://IP/read?format=1&device=80&size=32768' works, but adding the address option neccesary for write command (-> 'http://IP/read?format=1&device=80&size=32768&addr=0') fails reading?! I will investigate the sketch
EDIT: my working teensy sketch can be found here: http://wiki.samygo.tv/index.php5/Ethern ... _interface

Please check my dump after changing as supposed. I won't disconnect from wall until you checked and agreed

Re: C Series EEPROM research
seem ok. but why don't you change just these bytes instead of full dump?

Re: [howto] Switch boot partitions via micom eeprom C series
To complete my case i attached both states (1st active and 2nd active) as dumps of my micom EEPROM. Mind attachement comments.
Just for information: if you compare both that dumps with the one i posted previously (Micom_EEPROM_after_toggle_try.zip) you will figure out that the ascii string 'ger' changed to 'eng'. The reason is that tv was set to german before my tv's brick and after unbricking it let me walk through the setup-up steps where i chose englisch to quickly pass that. juuso' dumps show 'spa' so that dumps will most probably have been made on a tv set to spanish
