Hi, I have a LimeSDR v1.4s, I tried to run LimeTool --update and it screwed up everything.
At the moment I’m able to flash anything I want on the FX3 chip (using LimeSuiteGUI) but nothing on the FPGA.
LimeSuiteGUI shows right after connecting to the SDR:
[17:59:19] WARNING: Gateware version mismatch!
Expected gateware version 2, revision 14
But found version 0, revision 0
Follow the FW and FPGA upgrade instructions:
http://wiki.myriadrf.org/Lime_Suite#Flashing_images
Or run update on the command line: LimeUtil --update
[17:59:19] ERROR: Command not supported
[17:59:19] INFO: Connected Control port: LimeSDR-USB FW:4 HW:4 Protocol:1 GW:0.0 Ref Clk: -0.00 MHz
If I try to use the programming tool (FPGA Flash / FPGA Reset) I just get ‘Programming Failed: Error’.
This is what happens if I try to do the same using LimeUtil:
$ LimeUtil --fpga=/home/al/Downloads/LimeSDR-USB_HW_1.4_r2.14.rbf
Connected to [LimeSDR-USB [USB 2.0] 9060B00490F2B]
Gateware version mismatch!
Expected gateware version 2, revision 14
But found version 0, revision 0
Follow the FW and FPGA upgrade instructions:

Or run update on the command line: LimeUtil --update
Programming failed! Error
[ 0%] 32/574703 Bytes Programming failed! Error
Programming failed! : Programming failed! Error
Also, I tried to use any possible combination of:
Different FX3 firmwares: {Latest from downloads.myriadrf.org, Latest from git, Random ones}
LimeSuite version: {(Random) Old stable, Latest stable version, Latest version on git}
USB Data Cable: {USB2,USB3}
Power supply {USB3 internal, USB external, external 7.5/9 adapter, external 9v battery}
always with the exact same result.
Now I’m thinking about flashing it using an external JTAG interface, do you have any tutorial or suggestion about that?
Hi, thanks for the reply!
I have the latest version of LimeSuiteGUI installed, so I don’t have the Bitstream to FPGA but FPGA FLASH.
Here are some screenshots:
Hello @theal, I see that you are using the supplied USB break out lead, I found mine was problematic, suspect even though it has the “Dual” supply the cable is not up to scratch, can you carefully plug your LimeSDR directly into the USB3 Port of your PC and try the upgrade again?
The FX3 firmware has a *.img extension and select the file which corresponds to your hardware version, which should almost certainly be v1.4 (it’s printed on the board).
Hello @theal. I am having the same issue. Cannot reflash the FPGA firmaware. Tried everything. I think that there might be some memory corruption or something that’s stopping me from reading or writing anything into the chip. Did you get this issue resolved?
@andrewback I have tried installing the FX3 firmware numerous times. It installs properly but FPGA update fails. Having Gateware version mismatch issues. Any suggestions please?
Hey! Still broken for me, but I got a few ideas I will try them soon.
After I had struggled with all the tools/firmware&co and nothing was working, I unsoldered the flash chip, connected to a raspberry pi and…guess what: flashrom (linux tool) writes stuff into the flash chip and then it reads them back wrong.
After few tries (…and after I had bought 5 flash chips, all of them with the same problem), I spotted a pattern:
it writes few sectors correctly and then it writes a sector with wrong values (every time it’s a different sector).
So, I tried changing the write speed (10MHz, 5MHz, 1MHz, 100KHz) and I got always the same problem.
What happens is that, at some point, it starts ignoring/losing (and then shifting) bits, e.g. writing “20 20 20 20 20” might give “20 40 40 80 80”.
I asked to a friend of mine(electronic engineer) and he told me that this happened once to him and he solved it by adding a resistor in the CLK line: the “overdamping” of the CLK (0 -> 1) sometimes is read as multiple clock ticks.
im also having similar problems with my limesdr-mini
[01:07:47] ERROR: Read(64 bytes) failed
[01:07:47] INFO: Connected Control port: UNKNOWN FW:0 HW:0 Protocol:0 GW:0.0 Ref Clk: -0.00 MHz
no led light on board at all.
usb is recognized a bit with LimeUtil --find but cant do any --update and same for limesuitegui.
cant program fpga flash
any help would be much appreciated.
cant get into bootloader mode because i cant find the FX3 jumper.
is that for the limesdr-mini?
I recently installed spectogram which installs a modified GW, but upon restoring the fpga back to default one (i.e. using --fpga_restore). I am facing the same issue of not able to update the fpga firmware to latest.
Will need @Zack to advise on this one. It may be that you will now need to program via JTAG, but hopefully not. Could you also post the output of LimeQuickTest please.
docker run -v /dev/bus/usb:/dev/bus/usb -v /usr/share/LimeSuite/images/22.09:/root --privileged -ti gasparka/spectrogram bash
NOTE: I am assuming that the host machine has fpga images at the location /usr/share/LimeSuite/images/22.09
Inside the docker container run the below LimeUtil --fpga=/root/LimeSDR-Mini_HW_1.2_r1.30.rpd
