Various sub-projects around the UHD repository specify their own minimum
CMake versions (independent of UHD). We modify the minimum CMake
versions in the following way:
- All CMake files under firmware/ are bumped from 2.6 to 3.5. This is to
allow newer CMake versions to work with these files (CMake 4 and
beyond do no longer work if the minimum version is below 3.5). However,
note that these CMake files are so simple they will keep working with
older CMake versions, but that will require manually demoting the
minimum version. Because more people are using CMake versions newer
than 3.5 (especially with recent checkouts of UHD), this seems the
more compatible solution.
- The CMake files for extension_example and init_usrp are bumped to
3.12. This matches the version that UHD uses, which increases
compatibility.
- Bump firmware compat to 6.1
- Remove crossbar counter logic (the FPGA does *not* support crossbar
counters anymore, so we remove it from the firmware as well)
- Remove crossbar programming control (this is now provided by RFNoC
management packets)
- Remove UDP framing control (this is also provided by RFNoC management
packets)
- Remove Ethernet link/activity LED control (this has been handled by
the FPGA directly for years now)
- Add functionality to program transport adapter. The TA is programmed
directly on the settings bus, so for the most part, this is already
possible from the firmware. The only exception is the 'virtual'
register to program IP address and MAC at the same time. In the
firmware, it will perform an ARP lookup of the MAC address, and then
write the "normal" IPv4 address register in the TA, as well as the MAC
address registers.
- Updated bootram.coe
- Load EEPROM data into firmware memory to access from there instead of driving the I2C bus directly
- Fixed firmware performance issues by removing the popcntll() function and reducing frequency of background tasks to once every 10ms
- Added x300_mb_eeprom_iface to handle cases of devices with older and newer firmware
- Added checks for claim to device before driving the I2C bus
- Refactored SFP+ hotplug handler
- GigE link state comes from SFP+ status and PHY status
- Multiple tracing enhancements
- Bumped firmware compat number to 4
- Bumpled FPGA compat number to 10
