This change allow user to set RX LO of ad9371 to external or internal from args
constructor of usrp device.
new args is rx_lo_source value can be either internal or external:
If there's no rx_lo_source specified or invalid value, default rx_lo is used; which is internal LO.
Usage example:
usrp_application --args "rx_lo_source=external"
Currently, AD9371 turned on most of the calibration and hard coding the turning
on process during bringup time.
This change enables users to pass in a mask field for init ARM calibration and
tracking arm calibration at the time creating USRP device reference.
This mask field can be passed through device arguments of:
1/ init_cals : for init ARM calibration masks. This is defined in AD9371 UG-992
table 65. Default to 0x4DFF
2/ tracking_cals : for tracking calibration masks. This is defined in AD9371
UG-992 table 66. Default to 0xC3
Example of pasing in init calibration and tracking calibration mask
usrp_application --args "init_cals=0x4f, tracking_cals=0xC3"
NOTE: UHD currently expect user to input the correct init_cals and
tracking_cals. There's no mechanism to check if init mask and tracking mask are
valid. For example if the init mask field not mask 0x4f, the AD9371 will failed
to setup.
SPI interfaces and -lock, user EEPROM, radio regs, CPLD, dboard clock
control and GPIO expander can be initialized in Magnesium.__init__().
This shaves a little time off of the actual init() call and allows for
earlier failures.
Now, when claiming a device, the connection type will be stored as a
string in PeriphManagerBase. This way we can read out the current
connection type even when not currently inside an RPC call.
- Any RPC call with uncaught exceptions will result in additional
logging on MPM side
- Adds get_last_error() API call
- get_last_error() is populated by various methods within rpc_server.py,
but also from every uncaught exception
-update_fpga loads the FPGA image from the base class's update_component function
-checks if FPGA image is a bit or bin file, and converts to Zynq-compatible binfile if necessary
-update_component takes a byte array containing the data to be written,
and a dictionary containing the metadata of the component to be
updated
-The metadata must contain 'id' and 'filename'
-The metadata may contain an md5 hash ('md5')
- Number of samples for TDC measurement bumped back up to 512 (was
previously reduced because of slow sampling speed)
- Non-functional changes: Modified formatting to pacify PyLint
On the N310, there's a penalty for calling time.sleep(). This means the
polling loop was extremely slow for polling TDC updates. Now, it simply
polls as fast as possible. Note: This could hog the bus if run outside
of an initialization sequence, where no one else is using the bus.
BufferFS is a serialization format with CRC checking and optional
byte-alignment for records. It allows storing arbitrary blobs, together
with a 8-character identifier, in a contiguous buffer that supports
random access. This is suitable for storing arbitrary blobs in EEPROM,
but could also support other things.

The Magnesium daughterboards have GPIO port expanders, but both have the
same udev label. In order to specify which port expander to use, we pass
in the parent udev I2c device.
Prior to this commit, device_info was always an empty dictionary on all
dboard classes. The device_info dict is now auto-populated from the
EEPROM contents, if any were provided.
Dboard classes can still opt to amend that dictionary in specific class
implementations.

There are cases where we need to specify a parent device in order to
disambiguate GPIO devices with the same label. This lets you passing in
a parent udev device to clarify.
- Based on feedback from ADI, updated SYSREF sequencing for
meeting deterministic latency requirements.
- Changed majority of register addresses in nijesdcore.py to
constants.
- Corrected write data to SYSREF_CAPTURE_CONTROL to produce
the correct SYSREF toggle rate inside the FPGA.
