Bill-of-Materials

Please check the BOM.txt for the components needed. Most likely (except the R470OHM 2010) you may have all you need already.
Of course, you still need to purchase a part the FT2232HL CJMCU (e.g. https://s.click.aliexpress.com/e/_DeK6Oor )

Tips:

• This breakout is designed for the FT2232HL CJMCU board (e.g. https://s.click.aliexpress.com/e/_DeK6Oor )
  
• Pull-up Resistor is 470Ohm.
  
• Screws to hold the PCB to the 3D-printed case are 2x6mm.
  
• BE SURE to mount the FT2232HL with the FTDI chipset FACING UP!!!

UART (Channel A)

Command to run the UART console feature: Configure minicom/putty/whatever-terminal-you-are-used-to (e.g.
screen /dev/ttyUSB0 115200
screen -L /dev/ttyUSB0 115200
screen -L -Logfile UART.log /dev/ttyUSB0 115200)

JTAG (Channel B)

Command to run the JTAG debugging feature:
sudo openocd -f NANDo-Board_JTAG_OpenOCD.cfg -f target_device.cfg

SWD (Channel B) (this works on openocd v.0.11 but NOT on v.0.10!!!)

Command to run the SWD debugging feature (remember to move the SWD Enable switch on the PCB before using this feature!):

cd openocd-v.0.11
./openocd -s /opt/openocd/share/openocd/scripts/ -f /home/FOO/Desktop/NANDo-Board/OpenOCD_Configs/NANDo-Board_SWD_OpenOCD.cfg -f target_device.cfg

SPI Dumping (Channel B)

Command to run the SPI dumping feature:
flashrom -p ft2232_spi:type=2232H,port=B -r firmware.bin

In case you need also to write a SPI flash... please do enable the WRITE PROTECT (WP) Jumper on the PCB (i.e. SPI WP Enable).

NAND Dumping

Dump Raw Image:
yand_cli.py -r -f nand_raw_dump_withOOB.bin

Remove OOB Data:
python Nand-dump-tool.py -i nand_raw_dump_withOOB.bin -o nand_raw_dump_cleaned.bin --page-size 2048 --oob-size 64 --layout separate
OR
python Nand-dump-tool.py -i nand_raw_dump_withOOB.bin --layout=guess -I <ID-CODE-HERE> -o nand_raw_dump_cleaned.bin

Logic Analyzer with Pulseview

The strip pins AD0-AD7 labeled "Pulseview FTDI-LA" can be used as low-frequency Logic Analyzer Channels with Pulseview/Sigrok tool. Here the configuration

Multipurpose Pin Headers/Sockets

On the lower part of NANDo-Board's PCB there are some pin headers/sockets that are not connected with the FT2232HL. They are there just in case you need to mess-up with many flying-wires and you want to keep all connections clean and in order like with an usual breadboard, but with screwdown terminal blocks & co.
