Hi,

before running update, LimeUtil --find gave this output:  
LimeUtil --find

- [LimeSDR-USB, media=USB 3.0, module=STREAM, addr=1d50:6108, serial=0009062A00CE131B]

I then proceed to do an update:

LimeUtil --update  
Connected to [LimeSDR-USB [USB 3.0] 9062A00CE131B]  
[WARNING] Gateware version mismatch!  
Expected gateware version 2, revision 8  
But found version 2, revision 6  
Follow the FW and FPGA upgrade instructions:  
[http://wiki.myriadrf.org/Lime\_Suite#Flashing\_images](http://wiki.myriadrf.org/Lime_Suite#Flashing_images)  
Or run update on the command line: LimeUtil --update

Programming update complete!

However, after running the update, LimeUtil --find gives this output:  
LimeUtil --find

- [WestBridge , media=USB 2.0, module=STREAM, addr=04b4:00f3, serial=0000000004BE]

If I try to run update again, I get a weird error:

LimeUtil --update  
Connected to [WestBridge [USB 2.0] 4BE]  
[ERROR] Unsupported hardware connected: UNKNOWN[HW=0]

Programming update failed! : Unsupported hardware connected: UNKNOWN[HW=0]

Power reset did not help?

I unplugged and reconnected the LimeSDR-USB several times, but it keeps showing the same message

computer power reset? all info about the board? HW1.4? 1.3? LimeSuite GUI tells?  
try programming both --fpga and --fw from:

> **[myriadrf/LimeSDR-USB](https://github.com/myriadrf/LimeSDR-USB)**
>
> USB 3.0 version of the LimeSDR board. Contribute to myriadrf/LimeSDR-USB development by creating an account on GitHub.

hm? [http://downloads.myriadrf.org/project/limesuite/](http://downloads.myriadrf.org/project/limesuite/) different compiled versions  
maybe try 17.07 dir

</div>

How do I gather more info about the board? LimeSuite GUI connection settings shows the same message as LimeUtil --find, a “WestBridge [USB 2.0] 4BE” device.

So, How do I use the --fpga/–fw options? I see .rbf and .img files in that folder, but which are FPGA and which are FX3?

The .img is FX3 and .rbf is FPGA.

It doesn’t seem to be working:

> LimeUtil --find=“module=STREAM,serial=0000000004BE”

- [WestBridge , media=USB 2.0, module=STREAM, addr=04b4:00f3, serial=0000000004BE]

Not sure how to proceed from here

I see you’re using USB 2.0? I’d start by using a USB 3.0 port, as bandwidth aside USB 2.0 may struggle to supply enough power.

If you cannot program the FX3 microcontroller using Lime Suite / LimeUtil, I would suggest trying the Cypress utility:

[https://wiki.myriadrf.org/LimeSDR-USB\_User\_Guide#Flashing\_the\_USB\_3.0\_microcontroller](https://wiki.myriadrf.org/LimeSDR-USB_User_Guide#Flashing_the_USB_3.0_microcontroller)

Once the FX3 flash is programmed, then use Lime Suite to program the FPGA.
