Hi,
We would like to run an iperf utility for the throughput measurement.
However, its not part of the Release 9 image on the board of wp7608.
Could some one point me to the right source in pushing the opensource utilities(especially iperf) on the mangOH board.
Thanking in advance.
Hi
You can compile iperf from the Yocto that is provided for the modem. For example, with untar WP76 yocto: R16 Legato-Dist-Source-mdm9x28-SWI9X07Y_02.37.07.00.tar.bz2
sierra@NAMSE-LEGA01:~/DATA/Sierra/sierra_yocto_9x07/R16_02.37.07.00/swi_linux/yocto$ make dev

=== Matching recipes: ===
iperf2:
meta-oe 2.0.10
iperf3:
meta-oe 3.2

scp “bin” and “lib” folder from “build_bin/tmp/work/armv7a-neon-poky-linux-gnueabi/iperf3/3.2-r0/image/usr/” to WP76
On the modem, update your PATH and LD_LIBRARY_PATH.
