I can`t find 24C256 Debug Menu on D series. What is exact path to it on your TV?

I don't have the eeprom utility on my BD, but I have a similar TDM submenu. However, it is for the config eeprom, not the Micom's one

Interesting - eeprom cleaner is specially designed for E series only or it could be "back-used" on D series.

I don't know what is the TDM path to get to this. If its even possible...
Also the binary is called through a shell script, selecting for X9 and X10, so I don't know what EEPROM they really refer to.

Code: Select all

577fbcc t_ResetSubMicomEEPROM
57802a8 Control Type is [FACTORY_CTRL_EEPROM_COPY_MAIN_TO_DMD]
5782249  <<<< FOR SUB_MCM's EEPROM >>> id: [%d], name: [%s] value: [%d]
57829a4 ReWrite EEprom data!!!!!
57832e0 t_FAnetWriteEEPROM
57832f4 t_FAnetReadEEPROM
Etc etc.. look inside.

I'm quite sure it is the good one as it is connected to the micom processor.
Moreover, I think the language is 'eng' in your eeprom as it was 'fre' for me here. Not at the same place but my micom processor is different than yours (Renesas).

Compared dumps when made command toggle. Each timetwo bytes change:
(code removed, messed something with logs :))

Have to repeat all tests, completelly lost in logs. They are identic independent of what boot partition is selected. Just two times i got changing between toggling partitions: at address 0x03 (or is it 0x23, because of additional first line in rw mode?) (AD->B0->AD) and 00->02->00 at address 0x18.

Further testing on this Friday.
