Overview
The NanoFlashProg is an Flash programmer using Arduino Nano.
Currently supported chips are:
- Winbond 25Q128FV
This has been particularly designed to flash uboot bootloader on SPI Flash chips.
Hardware
The NanoFlashProg shield fit on an Arduino Nano. The full kit has:
- Mini USB port for serial comm.

Sketch
Software
A terminal emulator is required to communicate with the programmer. We recommend Cutecom. HyperTerminal or similar will also work as long as the emulator is able to send a file.
Usage
Connect to the programmer using settings 115200 8N1.
On connection the programmer will introduce itself and offer a prompt.

We recommend downloading uboot from pepe2k repository. Github link.
You must erase the chip before flashing uboot. At the prompt type e and enter. Then answer y at confirmation. This will take around 6 seconds to complete.
