USRP-2974 (Krypton) driver install and usage
Description
A quick walk thru on how to install the PCIe driver for Krypton and start using the device. The Krypton is a stand-alone SDR with a host controller with radio portion connected to the host via PCIe bus. The specifications for Krypton is here.
Installation / Starting of PCIe driver
From the COSMOS console, load an image that has a compatible UHD & kernel driver already installed. The image baseline-uhd.ndz or similar can be used.
console:~# omf load -i baseline-uhd.ndz -t sdr2-s1-lg1.sb1.cosmos-lab.org console:~# omf tell -a on -t sdr2-s1-lg1.sb1.cosmos-lab.org
Now ssh into the Krypton host and verify it is able to detect the radio on the PCIe bus. Use lspci to list all the devices that are detected.
root@sdr2-s1-lg1:~# lspci
In the output of lspci, search for Signal processing controller: National Instruments PXIe/PCIe Device. This means the host computer's PCIe controller sees the Krypton radio. Now download and install the PCIe driver so the UHD applications access the radio. Complete details on this driver is here.
root@sdr2-s1-lg1:~# wget http://files.ettus.com/binaries/niusrprio/niusrprio-installer-18.0.0.tar.gz root@sdr2-s1-lg1:~# tar -zxf niusrprio-installer-18.0.0.tar.gz root@sdr2-s1-lg1:~# sudo niusrprio_installer/INSTALL
After the installation is complete start the driver by loading it into the kernel modules.
root@sdr2-s1-lg1:~# /usr/local/bin/niusrprio_pcie start Making sure drivers are up to date... Module nikal is up-to-date Module nistreamk is up-to-date Module nibds is up-to-date Module niusrpriok is up-to-date Module NiRioSrv is up-to-date Loading: NiRioSrv niusrpriok Starting: niusrpriorpc
At this point use uhd_find_devices and uhd_usrp_probe query the radio.

Trouble shooting
FPGA version mismatch
If the above commands return with an error message stating an FPGA version mismatch, then we'll need to update the FPGA that is compatible with the current UHD version. The typical error message would be similar to the following:
[ERROR] [0/DmaFIFO_0] Major compat number mismatch for noc_shell: Expecting 5, got 2. [INFO] [MPM.PeriphManager] init() called with device args `clock_source=internal,time_source=internal,mgmt_addr=10.115.2.1,product=n310'. [ERROR] [MPMD] Failure during block enumeration: RuntimeError: FPGA component `noc_shell' is revision 2 and UHD supports revision 5. Please either up. Error: RuntimeError: Failed to run enumerate_rfnoc_blocks()
To update the FPGA following these steps.
root@sdr2-s1-lg1:~# /usr/local/lib/uhd/utils/uhd_images_downloader.py root@sdr2-s1-lg1:~# uhd_image_loader --args "type=x300" root@sdr2-s1-lg1:~# restart
Note: If the Krypton host is rebooted, the driver modules are NOT automatically reloaded into the kernel. So the command /usr/local/bin/niusrprio_pcie start has to be run on the Krypton host everytime it is power-cycled or rebooted.
root@sdr2-lg1:~# /usr/local/bin/niusrprio_pcie start
NI Driver does not build
While trying to build the NI driver following the instructions above, you may encounter an error regarding the do_munmap function not having enough input arguments. To fix, issue the following command to open the problematic C code file in nano:
nano /var/lib/nikal/5.0.0-29-generic/nikal/nikal.c
In nano, use CTRL-W to search for "do_munmap" and locate the following function:
static inline int nNIKAL240_do_munmap(struct mm_struct *mm, unsigned long addr, size_t len) { #if defined(nNIKAL1_kDoMunmapHasUf) return do_munmap(mm, addr, len, NULL); #elif defined(nNIKAL100_kDoMunmapHasAcct) return do_munmap(mm, addr, len, 1); #else return do_munmap(mm, addr, len); #endif }
Note that the third and final call to do_munmap is missing the fourth parameter. Add NULL as the fourth parameter so that the line reads as the following:
return do_munmap(mm, addr, len, NULL);
Save the file by typing CTRL-O, Enter and close by typing CTRL-X. Try building the driver again - it should proceed without issue.
