[Gnuk-users] Upgrading gnuk on a nitrokey start

[Remy van Elst]

I did try to flash NeuG to the device, but that resulted in a blinking
green LED and nothing else. Here's the command for reference:

    sudo stm32flash -w ../../neug/src/build/neug.bin -g 0x0 /dev/ttyUSB0

Output:

    stm32flash 0.5
