The gnICE+ is the latest and most feature complete Open Source USB High-Speed JTAG In-Circuit-Emulator for Blackfin processors.
It's more than 10x faster compared to the gnICE while still being a low cost solution.
It's designed to provide both mechanically and electrically reliable JTAG debugging and CFI NOR Flash programming via USB High-Speed.
The gnICE+ JTAG Adapter Cable is Open Source Hardware based on the FT2232H chip from Future Technology Devices International Ltd.
Supported Blackfin derivatives:
Schematics can be found on the Schematics page.
See the buy_stuff page for purchasing information.
The gnICE+ features six auxiliary signals routed to through hole pads, located besides the Mini-USB Jack.
|RXD||Channel B (BDBUS1) RXD||UART RXD (3.3V IO) signal may connect to Blackfin TXD|
|TXD||Channel B (BDBUS0) TXD||UART TXD (3.3V IO) signal may connect to Blackfin RXD|
|GP1||Channel A (ACBUS2) GPIOH2||This is a General Purpose IO Signal, which can be used to RESET the board|
|GP2||Channel A (ACBUS3) GPIOH3||This is a General Purpose IO Signal, which can be used to RESET the board|
|GP3||Channel A (ACBUS4) GPIOH4||This is a General Purpose IO Signal, which can be used to RESET the board|
|GND||Signal Ground||In case the gnICE is connect to the board via the JATG header this can be left unconnected|
