This 2014.11-rc3 release candidate introduces the remaining functionality originally intended for a 2014.09 release, as well as a number of improvements and bug fixes. As denoted by the name, the release has been rescheduled for November 2014.
This release candidate consists of the following versions:
- FPGA bitstream v0.1.1
- FX3 firmware v1.7.1
- libbladeRF v0.17.0
- bladeRF-cli v0.12.0
Major changes and additions include:
- Timestamp metadata support for the libbladeRF synchronous interface
- Example code is included in the API documentation and available in the libbladeRF/doc/examples directory.
- This is tightly-coupled with functionality and fixes introduced by FPGA v0.1.1.
- A majority of libbladeRF functions have been made thread-safe.
- libbladeRF support for a Cypress CyUSB3/CyAPI-based backend
- This backend has been found to be a useful alternative on some systems with USB3 controllers that exhibit issues with the libusb backend implementation.
- Fixes for LMS DC calibration issues
- FPGA fixes in v0.1.1 have addressed a timing issue that corrupted LMS register readbacks. This fixes issue #269, in which LMS DC calibration registers would become corrupted and read back as 31's.
- A bladeRF-cli change in v0.12.0 fixed issue #304, where TX DC calibration would fail, reporting that invalid values were encountered.
The remaining window of time up to the first official release is intended for documentation improvements and bug fixes. New features or major changes will be held off until the following cycle; they may be staged in a master-next branch if needed.
The following issue tracker items have been closed since 2014.09-rc2. Issues are listed first, with associated pull request items second, if relevant.
