GOWIN LittleBee development board

This small board (SKU TEC0117) for GOWIN FPGA is available from Trenz Electronics webshop. The JTAG programmer is on board - it is just a simple standard FT2223H MPSSE JTAG (empty FTDI EEPROM).

Pre programmed demo design is from RISC-V competition, it should show the following on the UART Terminal (115200, 8N1):


Note: depending on the production batch the boards may be unprogrammed from the factory. Note: you do not need GOWIN tools license to use the gowin programmer.

With empty FTDI EEPROM you need to select the second UART assigned to the board.

TIP: the GOWIN boards are delivered with empty FTDI EEPROM so they will enumerate as two UART's - it is OK to disable VCP loading for the channel A, then you only see one COM port assigned to the board. 


Select D2XX for Channel A and click program.
