How to configure FT601 USB3.0 chip?¶
Download FT600ChipConfigurationProgUtility_v1.3.0.2.zip , connect board and hit “Read Configuration” (make sure that any other software is closed and is not using the board). You should see following settings:
Figure 1: FTDI configuration
Ignore “Serial number” field. If any other setting are incorrect fix them and hit “Write Configuration”. Close utility and try to connect board to LimeSuite GUI.
I cannot connect board to LimeSuite GUI, no LEDs are blinking how can I recover my board?¶
Try using a different USB 3.0 cable or connect the device directly to a USB 3.0 port. The use of low-quality USB 3.0 cables and USB 3.0 hubs may result in power-related issues.
Check FT601 chip configuration, see How to configure FT601 USB3.0 chip? .
Reprogram FPGA FLASH memory using JTAG with latest GW lms7_trx_impl1_dualboot.mcs file. Check JTAG programming page and follow FPGA FLASH programming procedure.
If FLASH programming was successful you should see blinking LED1 after reapplying power to board.
If after fixing FTDI configuration and reprogramming FPGA FLASH you still cannot connect to LimeSuite GUI this would indicate problems with software setup that you are using or board is damaged.
