FT2232H核心模块电路

liyf

其实其他没有缓冲芯片的ft2232做的jtag都可以用该核心模块制作，只要对应引脚飞线就行，稍微见得麻烦点而已，其实这个反而方便，所有引脚都引出了


The FT2232H Mini modules can be used with blackmagic firmware or as FLOSS-JTAG device.
More Information can be found at the FT2232H Mini Module Serial Adapter page.
Important
Out of the box, there is NO power supply for the FT2232H because this can either done with USB or external 5V.
The pictures above show two different PCB versions. The suggested connections only apply to the right (latest) layout.
Connect: (for power supply over USB)

• CN3 pin 1 to CN3 pin 3
• CN2 pin group 1,3,5 to CN2 pin group 11,21 and to CN3 pin group 12,22
  

Pinout
UART

Use	Pin	Name
UART1 RX	CN2-10	ADBUS1
UART1 TX	CN2-7	ADBUS0
UART2 RX	CN3-25	BDBUS1
UART2 TX	CN3-26	BDBUS0

JTAG

Use	Pin	Name
JTAG1 TCK	CN2-7	ADBUS0
JTAG1 TDI	CN2-10	ADBUS1
JTAG1 TDO	CN2-9	ADBUS2
JTAG1 TMS	CN2-12	ADBUS3
JTAG2 TCK	CN3-26	BDBUS0
JTAG2 TDI	CN3-25	BDBUS1
JTAG2 TDO	CN3-24	BDBUS2
JTAG2 TMS	CN3-23	BDBUS3

Blackmagic firmwareFirst, get the VID/PID for your FT2232 device using 'lsusb'. Edit the file 'src/libftdi/platform.h' and change the VID/PID to match your hardware. Compile the application with the command:
make PROBE_HOST=libftdiFLOSS-JTAGWith the tool "FT_Prog" change the description the FT2232H to "FLOSS-JTAG".
识别为不同的设备主要就是那个93芯片内的vip/pid不同而已
