The Google Assistant is ready to help at any time. Just say ”OK, Google”, and ask a question or request a task – like “What’s the forecast today? If you have an Android phone, then you've probably used the Google Assistant before. Find out how easy it is to connect products to Google Home Mini. And you can use the hands-free smart tech to program a heap of things at the one time.
Please note the Kernel version, sources, initramfs and init.rc file will be useful in the second part of this series of article. The Linux Kernel version and compilation timestamp can be extracted from strings present in the binary data. Here, the Linux Kernel command line contains the mtdparts configuration variable.
Unpacking the Firmware Image
Bring your outdoors to life with our D.I.Y. ideas and advice. Smart home control, Music stream, local weather and live traffic report before I go somewhere. The Home Mini also has play pause controls, via a long press on the sides. Nest Mini is meant to sound much better though.
The procedure I used to program the correct configuration to the EEPROM is the following. This bitstream implements a simple FSM that will read all pages of the NAND Flash one by one and stream them to the FT2232H using the Sync FIFO Mode. I do find these two languages rather annoying to use.

”, but for people like me who weren’t looking for them then, but now want/need one, this is a good deal. Your phone is far more capable than a Google mini when it comes to invading privacy, no one seems to bat an eyelid. Could probably get Officeworks to price beat this. This app is hit or miss on whether it will work properly. When it doesn't, it absolutely doesn't and most likely will continue to not work for several days in a row.
It's simply breaking out the NAND Flash signals to traditional 2.54mm pitch connectors. Sending various configuration bitstreams to the FPGA. This is done by using the SPI protocol and a couple of additional GPIOs.
Make the most of your Google products
So far i control the wifi lights in my house which is much faster and more convienient than opening the app on my phone or grabbing the remote in the kitchen. Just saying "Hey google, turn the kitchen lights on/off" has been worth it just for that. But in my use-case, by having multiple google home mini/nests across multiple rooms i can use my voice to control my lights, heaters in different rooms. And also there is a feature called broadcast that sends out a voice message to each device. I have two, other than music, the one in the kitchen gets the most use. I find it much easier to use the voice control to set a timer or change the song rather than picking up my phone when I'm busy cooking.
Google Home and Google Home Mini are Wi-Fi enabled smart speakers powered by the Google Assistant. It can play music through Spotify, keep track of your diary, control compatible smart products, and more – all through simple voice commands. Google Home is a Wi-Fi-enabled smart speaker powered by the Google Assistant. Control compatible smart products from the video display or with voice commands. This sleek control centre is powered by the Google Assistant and can control media devices, lights, display photos and more. I picked up the nest mini earlier today from Bunnings .
This leaks both the names and sizes of all flash partitions. Using strings and grep against the firmware dump can quickly reveal interesting bits of information. I guess this nibbles swapping weirdness is caused by the way the low-level hardware BCH engine is actually working. Swap another time the nibbles of the computed BCH code. Another transformation was applied to the data before or after BCH encoding.
In our case, reading the datasheet of the NAND Flash used by the Google Home, the TC58NVG1S3HBAI6 gives the following details about the internal memory organization. The OOB section of each page is usually used to store Error Correction Code or ECC. This is needed because of how imperfect NAND Flash technology is. Bit flips are very common with these memories, and ECC are an efficient way to address the issue. The first thing to note is that the way the data is written to a NAND Flash is somewhat special. Each page contains data and a special section called OOB, the out-of-bound section.
The Google Home app is designed to show you the status of your home and keep you up to date with what you may have missed. Check in on your home anytime and see a recap of recent events. You can also get a notification if something important happens while you’re away.
Manually soldering thin wires to the BGA footprint for breaking out the NAND Flash lines could have been risky because of signal integrity issues. It wouldn't have been a very clean and, more importantly, reliable solution. Repeatedly desoldering and soldering back the NAND Flash would have been annoying and could have caused damage to to the PCB.
