Problem with LimeSDR mini

hi @all,

since a few weeks I am working with the LimeSDR and the LimeSDR mini.

The LimeSDR works fine and everything is okay, thank you for that great device :slight_smile:

The problem is with LimeSDR mini,whenever I try to access the device i get only the message in the console:

Read(64 bytes) failed
Write(64 bytes) failed

LimeUtil --find response:

*[LimeSDR Mini, media=USB 3.0, module=FT601, addr=24607:1027, serial=1D4257ACA6D09C]

LimeQuickTest response:

LimeUtil --update response:

Programming update failed!

if i try to connect the Lime Suite with the LimeSDR mini, i get the message:

[10:03:11] INFO: Disconnected control port

i found this post:

but if i try to read the Configuration i get this info:

At the end i have used a JTAG tool (ALTERA USB Blaster) and wrote LimeSDR-Mini_lms7_trx_HW_1.2.pof,
but no affects.

I think this must be a problem with the hardware and I have no more ideas.
I wanted to exchange the device, but the seller asked me to ask for help in the forum, maybe someone has a idea :slight_smile:
Thank you for help

@Zack, any further to suggest?

Hi @jonah1,

It looks like FPGA is not programmed (or doesn’t work for some reason). As you have USB blaster could you try to flash this file (if you flashed the different one previously):
https://github.com/myriadrf/LimeSDR-Mini_GW/blob/master/LimeSDR-Mini_bitstreams/LimeSDR-Mini_lms7_trx_HW_1.2.pof
You have to power-cycle the board after this procedure.

Hey @Zack,
Thank you very much for the quick answer.
Yes, I have the USB blaster an i have try to flash the file you mean:
https://github.com/myriadrf/LimeSDR-Mini_GW/blob/master/LimeSDR-Mini_bitstreams/LimeSDR-Mini_lms7_trx_HW_1.2.pof
The flash process finished successful, but the error did not fixed. Not even after a power cycle.

Hi @jonah1,

Then RMA it, please. Sorry for inconvenience.
