I’m just glad the JTAG option is almost always available still. That would be inexpensive, quick to develop and quite functional. That would connect to a replaceable board (onto plain old 100 mil header) where you can solder the TSOP IC (eventually the pads will need to be replaced), or another board that lets you solder wires if that’s your thing. I’d probably go with a ARM Cortex for simplicity, and a cheapo 2.4″ touch LCD off of ebay (all of $5), a micro USB port and a SD card socket. If I was gonna be doing lots of dumping, I’d rather spend extra time to get a better dumper. Like using a cheap ARM MCU (no, it’s not complicated) or even any other cheap MCU that can do USB (the plain old FX2LP comes to mind), or just dumpin to a SD card. Otherwise, there’s plenty of other good solutions that are much faster. Most equipment with NAND flash has a plain old JTAG port to program them at the factory. In most cases, all of that is unnecessary.
Posted in Arduino Hacks, hardware Tagged arduino, NAND flash, reader, reverse engineering Post navigation Or if you can spring for an FTDI FT2233H breakout board, you can read a NAND flash fast using essentially the same techniques as those presented here. If you haven’t ever done so, pull something out of your junk bin and give it a shot! If you’re feeling DIY, or need to read a flash in place, check out this crazy solder-on hack. With TSOP breakout boards selling for cheap, all that prevents you from reading out the sweet memory contents of a random device is a few bucks and some patience.
When you come back, the data will be dumped and you will have only invested a few minutes of human time in the project. It’s pretty modular, and if you’ve got a NAND flash that needs other low-level bit twiddling to give up its data, you should be able to get something up and working quickly, start it running, and then go have a coffee for a few days.
Nand x read bad block 258 code#
Instead, the code is built for hackability. We’re not sure which is the binding constraint, but neither of these methods are built for speed.
Nand x read bad block 258 serial#
His Arduino code reads the NAND using the notoriously slow digital_read() and digital_write() commands and then dumps it over the serial port at 115,200 baud. First on his list? A simple NAND flash reader, for exactly the same reason that Willie Sutton robbed banks: because that’s where the binaries are.Īs it stands, ’s first version of this tool is probably not what you want to use if you’re dumping a lot of NAND flash modules. Is starting up a project to make a “Super Reverse-Engineering Tool”.
