I got my LimeSDR-USB, unpacked it, connected it to USB-3 port, updated the firmware with `LimeUtil --update`, then I try `LimeQuickTest` and sometimes I got something like this: ```auto [TESTING STARTED] ->Start time: Fri Jan 17 18:00:09 2020 Warning: Multiple devices detected, connecting to the first device Read(64 bytes) failed Gateware version mismatch! Expected gateware version 2, revision 21 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 Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Undefined/Failure ->Device: LimeSDR-USB, media=USB 3.0, module=FX3, addr=1d50:6108, serial=000907060244273B Serial Number: 000907060244273B [Clock Network Test] ->FX3 GPIF clock test Undefined/Failure Undefined/Failure ->FX3 GPIF clock test FAILED ->Si5351C test Undefined/Failure Read(64 bytes) failed FAILED ->ADF4002 Test Write(64 bytes) failed FAILED ->VCTCXO test Read(64 bytes) failed FAILED ->Clock Network Test FAILED [FPGA EEPROM Test] ->Read EEPROM ->Read data: 12 0C 06 12 0C 06 02 ->FPGA EEPROM Test PASSED [LMS7002M Test] ->Perform Registers Test Read(64 bytes) failed SPI_write() failed Read(64 bytes) failed SPI_write() failed Read(64 bytes) failed SPI_write() failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed ->LMS7002M Test FAILED [RF Loopback Test] Note: The test should be run without anything connected to RF ports ->Configure LMS Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed SetFrequencyCGEN(491.52 MHz) failed Failed to set sample rate ->RF Loopback Test FAILED => Board tests FAILED <= Elapsed time: 3.17 seconds ``` But most of the time this: ```auto [TESTING STARTED] ->Start time: Mon Jan 20 09:32:21 2020 Warning: Multiple devices detected, connecting to the first device ->Device: LimeSDR-USB, media=USB 3.0, module=FX3, addr=1d50:6108, serial=000907060244273B Serial Number: 000907060244273B [Clock Network Test] ->FX3 GPIF clock test Test results: 31209; 34965; 38721 - PASSED ->Si5351C test CLK0: 17554 / 17554 - PASSED CLK1: 17554 / 17554 - PASSED CLK2: 17554 / 17554 - PASSED CLK3: 17554 / 17554 - PASSED CLK4: 17554 / 17554 - PASSED CLK5: 17554 / 17554 - PASSED CLK6: 17554 / 17554 - PASSED ->ADF4002 Test Result: 10 - PASSED ->VCTCXO test Results : 5112962 (min); 5113095 (max) - PASSED ->Clock Network Test PASSED [FPGA EEPROM Test] ->Read EEPROM ->Read data: 12 0C 06 12 0C 06 02 ->FPGA EEPROM Test PASSED [LMS7002M Test] ->Perform Registers Test ->External Reset line test Reg 0x20: Write value 0xFFFD, Read value 0xFFFD Reg 0x20: value after reset 0x0FFFF ->LMS7002M Test PASSED [RF Loopback Test] Note: The test should be run without anything connected to RF ports ->Configure LMS Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed Read(64 bytes) failed ... ``` The manual (LimeSuiteGui) test also doesn’t work as I cant get pass the open ini file, which fails with the same error message. So what should I do? ---

Hi @liborw, Could you please program this gateware: [https://1drv.ms/u/s!AsTX3WCH\_RLCjU0OGJICP25t4kuM?e=qUZx8f](https://1drv.ms/u/s!AsTX3WCH_RLCjU0OGJICP25t4kuM?e=qUZx8f) as described here, see section 4: [https://wiki.myriadrf.org/LimeSDR-USB\_Board\_Programming](https://wiki.myriadrf.org/LimeSDR-USB_Board_Programming) Then run tests again and let me know, please.
