Hi all,
I am using an X410 with X4_200 FPGA and latest FW as downloaded by
uhd_images_downloader -t sdimg -t x4xx. This initially was working
(uhd_usrp_probe and other calls went through fine) using UHD 4.4.0.0 on the
host.
In order to use DPDK, I pulled the UHD repo from version branch V4.4.0.0 and
recompiled with the ENABLE_DPDK flag turned on. After doing this, I sanity
tested the newly compiled and installed UHD without DPDK.
Here is the output from uhd_usrp_probe:
[INFO] [UHD] linux; GNU C++ version 11.3.0; Boost_107400; DPDK_21.11;
UHD_4.4.0.heads-v4.4.0.0-265-ga2a04e31
[WARNING] [PREFS] Loaded config from /root/.uhd. This location is considered

[ERROR] [MPMD] MPM major compat number mismatch. Expected: 5.2 Actual: 4.4.
Please update the version of MPM on your USRP device.
Error: RuntimeError: MPM major compat number mismatch. Expected: 5.2 Actual:
4.4. Please update the version of MPM on your USRP device.
I don’t understand where 5.2 has come from. It looks like the host UHD is
expecting 5.2. However the branch of UHD host that I compiled is definitely
UHD_4.4 as show in the first line of the output. Running uhd_images_downloader
again after recompiling still pulls the same sdimg file as before so updating
the FW again doesn’t help.
Anyone know what’s going on here?
Thanks,
Victor
