NANDway
- Solder 3.3V regulator on Teensy (and cut 5V pad)
- Flash the HEX to the Teensy
- Solder all control + I/O wires + Ground
- Crash it (it will beep and blink red led), press power button to have a solid red led
- Make sure to use the right nand id for nandway.py
- Dump it
Notes
<judges> nand powered with 3.3v by atx doesnt work <judges> nand powered by teensy requires huge delays to work kind of reliable <judges> teensy powered by usb, nand powered by external psu with 2v works like a charm.. <judges> thats why nandway worked for me.. it's slow. my own version is almost twice as fast and only worked on my first nand. second one always gave errors.. <judges> powered by teensy seems to be right on the edge of whats still working <judges> but only with 10ms delays between page reads.. <judges> current power draw is 1.13amps at 2v <judges> nand control lines are pulled high by starship and teensy isnt able to pull them low <judges> 2v-2.5v works fine <judges> stops working at 2.8v
