    Usb to i2c eeprom programmer ??

    Hello guys ..
    For 3 days i was looking online about how to read and write eeproms using i2c protocol, like you have a device has an eeprom within an IC and the board has i2c pins (SDA, SCL) and I'm trying to read and write this eeprom . But I failed to find a way!!! All what i found is you have to write your own software !!

    I just need to select an address and read or write !! That's it

    I have ch341a programmer i was able to dump the eeprom but it was not perfect i couldn't select any address !! Just read every device on the bus !!!

    Anyone know any usb to i2c adapter or how can use the ch341a to do what i need !

    Thanks guys. 😘😘

    so you want to read the chip in-circuit?

    maybe alternate software can choose the address.

        Thinkpad t480s, completely dead after BIOS flash using CH341A programmer
        by what_1282105
        Following this guide (https://www.reddit.com/r/thinkpad/co...g_and_flashing) i re-flashed my t480s BIOS using an external (CH341A) programmer. The flash didnt work, so i reverted back to my BIOS backup successfully. The BIOS in the chip and the BIOS backup file are identical according to windows' file compare. The revert, however, didnt work: the only thing the computer does is flash the power button 3 times when AC power is connected. I've tried unplugging the CMOS battery, holding the reset button and holding down the power button- no signs of life....

        Q: I have a bios request,i can`t post my backup as i can`t read from the chip.

        A: If you can`t read from it how do you expect to write to it ?.

        Q: Why is my bios chip unreadable ?.

        A: The programmer is faulty or has a worn or broken zif socket.

        The USB cable is frayed,connector pins worn or some other physical damage.

        Not enough amperage or voltage to power the programmer properly.

        Problems writing MX25L25673G
        by modtool
        Hi to all, I'm facing a problem writing to an MX25L25673G SOIC-16 bios chip (part of an HP EliteOne 1000 G2 27") with a Willem programmer 5.0B (with software PCB98D12c4).
        I know my programmer is old and I've planned to buy a new one but it worked until now with every eeprom I've faced in different devices, this is the first time that is giving me this kind of problem and I need to urgently solve it because I've already changed the fried southbridge and cleaned its ME fw, so I need to finish the last step of the repair.
        This Willem supports some 256Mbit eeprom, I can choose between...
