DLP-USB1232H based SPI programmer schematics In order to use the DLP-USB1232H device as SPI programmer you have to setup a small circuit (e.g. On a breadboard). See the schematics for details (you can also for easier printing). What you will need: Quantity Device Footprint Value Comments 1 — —. 1 Breadboard — —.

Many Jumper wires — —. 1 DIP-8 SPI chip — — This is the chip you want to program/read/erase. 1 3.3V voltage regulator TO-220 3.3V E.g. LD33V or LD1117xx. 1 Electrolytic capacitor single ended 100nF.
1 Electrolytic capacitor single ended 10uF. Instructions and hints:. You must connect/shorten pins 8 and 9, which configures the device to be powered by USB. Without this connection it will not be powered, and thus not be detected by your OS (e.g. It will not appear in the lsusb output). You need a 3.3V voltage regulator to convert the 5V from USB to 3.3V, so you can power the 3.3V SPI BIOS chip. You can probably use pretty much any 3.3V voltage regulator, e.g.
LD33V or LD1117xx. For usage on a breadboard the TO-220 packaging is probably most useful. You have to connect two capacitors (e.g.
100nF and 10uF as per datasheets, but using two 10uF capacitors, or even two 47uF capacitors also works in practice) as shown in the schematics, otherwise the voltage regulator will not work correctly and reliably. Connect the following pins from the DLP-USB1232H to the SPI BIOS chip:. 18 (SK) to SCLK. 16 (DO) to SI. 2 (DI) to SO. 5 (CS) to CS#.
The WP# and HOLD# pins should be tied to VCC! If you leave them unconnected you'll likely experience strange issues.
All GND pins should be connected together ( pins 1 and 10 on the DLP-USB1232H, pin 8 on the SPI chip, pin 1 on the voltage regulator). You have to invoke flashrom with the following parameters: $ flashrom -p ft2232spi:type=2232H,port=A On older flashrom versions the syntax was: $ flashrom -p ft2232spi:ft2232type=2232:port=A Photos:.
Module and parts FTDI FT2232H Mini-Module The can be used with flashrom for programming SPI chips. Where to buy: FTDI FT4232H Mini-Module The can be used with flashrom for programming SPI chips. Where to buy: openbiosprog-spi is an Open Hardware USB-based programmer for SPI chips, designed. It uses an FTDI FT2232H chip and features either a DIP-8 socket or a pinheader where jumper-wires can be attached.
The user-space source code is part of flashrom, the schematics and PCB layouts are licensed under the license and were created using the open-source EDA suite (GPL, version 2). For more information and downloads, including a parts list, Gerber file downloads, recommended Kicad settings, and recommended PCB manufacturer settings, see. Usage: $ flashrom -p ft2232spi:type=2232H,port=A Photos:. RushSPI v0.1 Amontec JTAGkey/JTAGkey2/JTAGkey-Tiny The can be used with flashrom for programming SPI chips.
And should work, if you add them to ft2232spi.c ( untested). Where to buy: Usage: More info can be found on on.
You need a 3.3V voltage source - see above for details. Connect the following pins from the JTAGkey2 to the SPI BIOS chip:. 1 (Vref) to VCC. 5 (MOSI/TDI) to SI.
7 (CS#/TMS) to CS#. 9 (CLK/TCK) to SCLK. 13 (MISO/TDO) to SO. 20 (GND) to GND.
The WP# and HOLD# pins should be tied to VCC. The 'Cable pinout' picture below shows the colors on the breakout cable. Amontec JTAGkey-tiny Olimex ARM-USB-TINY/-H and ARM-USB-OCD/-H The (VID:PID 15BA:0004) and (15BA:0003) can be used with flashrom for programming SPI chips. The (15BA:002A) and (15BA:002B) should also work, though they are currently untested. The following setup can then be used to flash a BIOS chip through SPI.
Pin (JTAG Name) SPI/Voltage Source 1 (VREF) VCC (from Voltage Source) 2 (VTARGET) VCC (to SPI target) 4 (GND) GND (from Voltage Source) 5 (TDI) SI 6 (GND) GND (to SPI target) 7 (TMS) CE# 9 (TCK) SCK 13 (TDO) SO On the ARM-USB-TINY, VREF, and VTARGET are internally connected, and all the GND lines (even numbered pins, from 4 to 20) share the same line as well, so they can be used to split VCC/GND between the voltage source and the target. The voltage source should provide 3.0V to 3.3V DC but doesn't have to come from USB: it can be as simple as two AA or AAA batteries placed in serial (2 x 1.5V). Invoking flashrom: You first need to add the -p ft2232spi option, and then specify one of arm-usb-tiny, arm-usb-tiny-h, arm-usb-ocd or arm-usb-ocd-f for the type. For instance, to use an ARM-USB-TINY, you would use: $ flashrom -p ft2232spi:type=arm-usb-tiny Openmoko The openmoko debug board(which can also do serial+jtag for the openmoko phones, or for other phones) has Informations The openmoko debug board can act as an SPI programmer bitbanging the FTDI(no need of an openmoko phone), you just need:. a breadboard. some wires.
The openmoko debug board(v2 and after,but only tested with v3) The voltage is provided by the board itself. The connector to use is the JTAG one(very similar to what's documented in the previous section(Olimex ARM-USB-TINY/-H and ARM-USB-OCD/-H ) Building WARNING this was tested with 3.3v chips only. Here's the pinout of the JTAG connector of the openmoko debug board(copied from ARM-USB-tiny because it's the same pinout): Pin (JTAG Name) SPI/Voltage Source BIOS Chip connector name 1 (VREF) VCC (from Voltage Source) VCC (3.3v only) 2 (VTARGET) VCC (to SPI target) Not connected 4 (GND) GND (from Voltage Source) Ground 5 (TDI) SI DIO (Data Input) 6 (GND) GND (to SPI target) Not connected 7 (TMS) CE# CS (Chip select) 9 (TCK) SCK CLK (Clock) 13 (TDO) SO DO (Data output).

Product Description The AnalogLamb ESP32 Programmer is an easy-to-use USB-to-Serial adapter based on the CH340 IC from WCH. It works 3.3V systems and should auto install on most operating systems without the need for additional drivers. The Serial Basic uses the CH340 IC to quickly and easily convert serial signals to USB.
It’s a great lower-cost alternative to the extremely popular FTDI. Features of ESP32 Programmer ( CH340 ). Full speed USB device interface, conforms to USB Specification Version 2.0. Supports baud rate varies from 2400bps to 115200bps. Hardware full duplex serial interface, set transceiver buffer.
3.3V 800mA LDO. LED Indicator.
Supports Auto download circuit. A Reset Button. Interface to ESP32: +3.3V – RX – TX – IO0 – EN – GND. The ESP-WROVER-KIT is a newly-launched development board built around ESP32. This board is compatible with ESP32 modules, including the ESP-WROOM-32 and ESP32- WROVER.
The ESP-WROVER-KIT features support for an LCD and MicroSD card. The I/O pins have been led out from the ESP32 module for easy extension. The board carries an advanced multi-protocol USB bridge (the FTDI FT2232HL), enabling developers to use JTAG directly to debug the ESP32 through the USB interface. The development board makes secondary development easy and cost-effective.
