    NVidia bumpgate
    by piernov
    Just archiving everything related to bumpgate since most stuff has disappeared from Google. Maybe people will finally take the time to read some of it and stop shouting "reflow gpu" at every occasion but rather try to understand what the real issue is…
    Interesting parts about the failure analysis are "Why Nvidia's chips are defective" and "Why Nvidia's duff chips are due to shoddy engineering"


    May complete this post at a later date with more details.
    Basically issue is a combination of thermal dissipation of the chip with hotspot,...

    Add chip support to EZP2019, EZP2019+, EZP2020, EZP2023, EZP2025, MinPro Programmers
    by SMDFlea
    This is a Github project, i have not used this software as i don`t own any of these programmers.The software looks good though,so i might just
    have to buy one,you can never have enough programmers


    QT based editor chip database for EZP2019, EZP2019+, EZP2020, EZP2023, EZP2025, MinPro programmer devices.

    For linux:

    Access to flashrom archive on eletronicabr.com (?)
    by badcappo
    Hi there, looking for the flashrom-extension that is presented by a user called "Jack O'Neo" over on eletronicabr.com -> First post on Link: https://eletronicabr.com/forums/topi...s-para-windows

    The archive seems super useful to add more chip support to flashrom so that it becomes possible to read flash content from additional ECs e.g. ENE KB9022 which are used on many boards. However, the forum seems to have a tedious credit farming process to get to the download link . Maybe someone with access...

    Capture digital data between microcontroller and led driver
    by orgamisho
    Hello, I have a device which uses 3 7segment displays (4 digits each) controlled by a single led driver (TM1629A) which is controller by a microcontroller (MS51FB9AE).

    I want to capture the communication between the 2 ICs, so I can decode it and read it from PC with USB cable.
    The problem is that this task is slightly over my skills and I have no experience is such tasks.

    I would be grateful if somebody give a hint how can I read and decode the digital signals or share a source where I can educate myself on this matter.
    I have no idea what protocol is...

    Aiper Scuba X1 Pool Cleaner Robot
    by iTec
    Hello everyone, I'm not really sure if this is the right place to actually post about this, but i have Aiper Scuba X1 that I'm trying to read the Microcontroller data from. The chip is National N32G455. After dismantling the unit I found a Debug connector and on the backside of the board 6 point that reads: GND RX VCC SWD TX SWC. I'm familiar with Nuvotons, MECxxx, ITE chips but NOT these kinds of microcontrollers. I need someone who can direct me to what's needed to read it ONLINE as they have coated the entire board. I got the ST-Link yesterday and connected the wires as shown in the picture...
