NANDopen

###
This introduction is an open source project ported from Github: https://github.com/bbogush/nand_programmer. It is an open source NAND programmer based on STM32. I hope more enthusiasts can improve it.

#### Record

- 2022-11-29 The attachment `NANDO_Installer_x64_win10_3.4.2.exe` is a Windows 10 64-bit client, and the PCB version required is 3.4
- 2022-12-08 Due to the epidemic, the PCB just arrived today, and I took the time to put it in The board was welded by hand. It took two hours to solder the board. The main reason was that the 100-pin microcontroller was not easy to assemble and soldered easily.
- The program can be brushed directly according to the steps of the original author, that is, replacing the STM tools with GD tools, it is very simple!

#### Application (linux)

#### Features
> I won’t go into detail here, I believe all of you are much better at English than I am
- USB interface
- PC client software for Linux & Windows.
- TSOP-48 socket adapter for NAND chip (compatible with TL866 adapter)
- TSOP-48 solder adapter for NAND chip
- 8 bit parallel NAND interface
- SPI interface
- 3.3V NAND power supply
- NAND read,write and erase support
- NAND read of chip ID support
- NAND read of bad blocks
- NAND bad block skip option
- NAND include spare area option
- Open KiCad PCB & Schematic
- Open source code
- Read & Write LEDs indication
- Extendable chip database
- Chip autodetection
- Firmware update
#### Disadvantages
>- Low flash write speed on Windows 10. Probably issue with driver.
> - No support of ECC calculation. In order to recover some device firmware the dump with spare area is required.

It should mean that writing is slower in Windows 10 system, which may be a driver problem.
There is no ECC calculation, some firmware may need to be dumped!
#### Supported chips
- Parallel NAND:
K9F2G08U0C, HY27US08121B, TC58NVG2S3E, F59L2G81A, MX30LF2G18AC and others.
See full list of supported chips qt/nando_parallel_chip_db.csv
>Full list in qt/nando_parallel_chip_db.csv file, You can add it yourself, The attachment can be seen after decompression.

- SPI flash
AT45DB021D, MX25L8006E, W25Q16JV and others.
See full list of supported chips qt/nando_spi_chip_db.csv
>The complete list is in the qt/nando_spi_chip_db.csv file. You can add it yourself. You can see it after decompressing the attachment.
#### Original application & firmware
text: You can download host application deb package for Ubuntu/Windows installer, firmware binary for STM32, schematic and gerber files from Google Driver.
> It means that they are all on Google Cloud Disk, and of course they cannot be accessed in China. Yes, here I will move domestically.

#### License
original text:
In general the sorce code, PCB and schematic are under GPLv3 license but with limitations of:
firmware/libs/spl/CMSIS/License.doc
firmware/libs/spl/STM32_USB-FS-Device_Driver/ - http ://www.st.com/software_license_agreement_liberty_v2
firmware/usb_cdc - http://www.st.com/software_license_agreement_liberty_v2`
> The general idea is to follow the GPLv3 agreement. Of course, many domestic people will ignore this. You must not do this~~


#### WiKi
original text: Check WiKi page for more information.`
>Here is a link to Github. I wonder if you can access it. The address is: https://github.com/bbogush/nand_programmer/wiki

#### The porter said
- I don’t know if the platform has this project. I searched for nand and it seems No relevant ones were found, most of them are SPI programmers.
- I moved this project because my classmate Xiao Ai was bricked by me. It costs several hundred to buy a nand. It is too expensive and I can’t afford it.
- The project wiki is still very helpful. If a friend cannot access it, just leave a message and I will find a way to synchronize it to China.
- The attachments of Google Cloud Drive are very large, I will try my best to download them all.
- The attachment nand_programmer was downloaded on 2022-11-24. If Github is updated, I should upload it simultaneously.
- This supported nand film seems to be very few, but you can actually add it by yourself. It is quite easy to read the instructions.

### **Finally, I wish you all no bricks in flashing your phone! **
