In this section you can find frequently asked questions related to LimeSDR-Mini v2.2 board
Avoid vague explanation of encountered issues. Try to provide as many relevant information as you can, for e.g:
- What hardware are you using? Write exact board name and version as you see on silkscreen.
- What software and version are you using?
- What gateware version are you using?
- Was it working before?
- Did you modified hardware, software or gateware? If so explain your modifications.
- Provide steps to reproduce the issue.
- First read this FAQ and go trough available documents in https://limesdr-mini.myriadrf.org/
- Try to search https://discourse.myriadrf.org/ maybe someone already had similar issue, if not - post your question there.
- For HW related issues check LimeSDR-Mini-v2 GitHub repository.
- For GW related issues check LimeSDR-Mini-v2_GW GitHub repository.
- For SW related issues check LimeSuite GitHub repository
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.
- 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.
