70 | 1 | laforge | |
71 | 29 | laforge | In terms of OsmoTRX for LimeSDR, we now have @osmo-trx-lms@ which avoids the previously complex driver stack with UHD, SoapyUHD, SoapySDR, etc. All you need in terms of dependencies is: |
72 | 15 | laforge | * "LimeSuite":https://github.com/myriadrf/LimeSuite.git containing the actual drivers and utilities for LimeSDR (*version 17.09 or later required*) |
73 | 1 | laforge | ** for LimeSDR-mini, you will need 17.10 or later |

84 | h3. Verifying the driver stack |
||
85 | |||
86 | You can ensure that LimeSuite recognizes your device using the *LimeUtil* part of LimeSuite: |
||
87 | |||
88 | <pre> |
||
89 | 18 | pespin | $ LimeUtil --find |
90 | * [LimeSDR-USB, media=USB 3.0, module=STREAM, addr=1d50:6108, serial=0009060B00xxyyzz] |
