BQ2060A: Unseal bq2060

Hello Sergey,

The bq2060a has the unseal code implemented in hardware: e2e.ti.com/.../95216

Let me check if we can open this information, since it is implemented in hardware I don't believe we can release the unseal commands.

Sincerely,

Wyatt Keller

Links do not open.
I will clarify my question.
I was able to change the EE 0x3F cell from FF to BF through the LPT adapter, after that I reset bq 2060 and was able to work normally with eeprom. I did all this in the UBRT-2300 and BE2Works programs. This was all done through the controller !!!
Why can't the official software do this? I think it is possible, you just need to know the secret command.
I read the instructions, it requires soldering to the memory. I'm asking about a purely software solution to the problem.

That is, with the seal flag, I could read and write memory through bq2060.
Here is the proof

Hello Sergey,

I would recommend you user a logic analyzer on the commands you are sending with the other communication adapters, you should be able to use the pro tab for the EV2200 to recreate the commands.

I'm talking about the fact that third-party software can provide access to eeprom even with the seal flag, and proprietary software does not provide access to eeprom with the seal flag.
What command should I enter on the PRO tab? This command is not included in the instructions.

This is what I see following the link.

I proceed from the fact that now you can disclose information on how to have programmatic access to eeprom on "old" controllers with the seal flag!

I will repeat once again I could have access and program eeprom 24C01 when the flag was seal.
This was all done through the controller via the LPT-Phillips adapter: FF (11111111) -> BF (10111111). I did it SOFTWARE using third-party software - UBRT-2300.

Not getting soldered to memory.
After that, I turned off the power from the bq2060, then connected the power and was able to work with the eeprom in the ev2200-60 with memory. That is, UBRT-2300 made it possible to do everything technologically, and not as difficult as the proprietary software.
Do you believe me?
I didn’t have to do hardware connection as written in the proprietary software.

I can change eeprom with this bq2060 state in the UBRT-2300 program.

Hello Sergey,

You should not be able to access the EEPROM and edit memory if it is SEALED, if you are trying to re-create the commands being sent on a new communication interface device then you will most likely have to sniff the communication lines to see what is actually being sent.
