monerujo-hw

Monerujo Firmware for The Sekura Monero Hardware Wallet

Prerequisites

• This is a GNU MCU Eclipse project
• sudo apt-get install gcc-arm-none-eabi
• libopencm3 in /opt (don't forget to make there as well)
• dfu-util to program the device over USB - see the sekura project for more details

udev Rules

SUBSYSTEM=="usb", ATTR{idVendor}=="0483", ATTR{idProduct}=="df11", MODE="660", GROUP="plugdev"
SUBSYSTEM=="usb", ATTR{idVendor}=="f055", ATTR{idProduct}=="c0da", MODE="660", GROUP="plugdev", ENV{ID_MM_DEVICE_IGNORE}="1"

Programming

dfu-util -a 0 -s 0x08000000:leave -D monerujo-hw.bin

Running

As the USB I/O is blocking you MUST connect to the device with a serial terminal. For Linux, use screen /dev/ttyACM0 (maybe ACM1 - check the /dev directory). For Windows I suggest TeraTerm. Terminal output will show the generated keys as well as other debug info.
