LA9310 iqplayer repository

la931x_iqplayer repository contains basic application allowing to stream time domain IQ samples with la9310 SOC. It includes VSPA firmware source code. It includes host linux scripts to control VSPA firmware. It also includes host linux library and application example.

Requirements

• This firmware is using vspa kernels from https://github.com/nxp-qoriq/la931x_vspa_common
• This firmware can be used with LA9310 PCI driver located at https://github.com/nxp-qoriq/la93xx_host_sw
• A default linux integration is provided for imx8mp platforms at https://github.com/nxp-real-time-edge-sw/yocto-real-time-edge/tree/la93xx
• Linux VSPA tool chain is freely availabel when downloading eval version of CodeWarrior for VSPA 10.3.0 or at https://www.nxp.com/lgfiles/sdk/la1224/imx-la9310-sdk-10/cwvspa.vbeta_14_00_781_vspa.linux.tgz

Libraries

This repository includes following elements:

• iqplayer_cwproj source code, Makefile and CW projects allowing to compile VSPA firmwares supporting usecases 1T1R, 1T, 1R, 1T2R.
• host-utils linux user space utilities:
  • Basic linux shell scripts to start/stop transfers ./iq-replay.sh, ./iq-capture.sh, ./iq-stop.sh
  • iq_mon : statistic monitoring showing traffic in various dma/fifos
  • iq_trace : dump VSPA trace information used to debug/profile VSPA firmware
  • iq_app/lib_iqplayer : Application example, showing how to stream traffic to/from upper stack

Compile iqplayer firmware and utilities

set compiler install path default (VSPA_TOOL ?= /opt/VSPA_Tools_vbeta_14_00_781)

make
make install
scp -r install/* root@<targetIP>:/

Usage - Play/Capture waveforms from/to binary files

load and start VSPA firmware

 ./load-la9310.sh

confugre RF (optional for axiq loopback or breakout card)

 ./config_run_rf.sh limetx
 ./config_run_rf.sh limerx

play (repeat) waveform from file

 ./iq-replay.sh ./tone_td_3p072Mhz_20ms_4KB1200_2c.bin 1200

capture (one time) iq samples into file

 ./iq-capture.sh ./iqdata.bin 1200

capture (repeat) in DDR buffer

 ./iq-capture-ddr.sh 1200
 ./iq-stop.sh
 bin2mem -f iqdata.bin -a 0x9CC00000 -r 4915200

digital/axiq loopback using dfe app control

 mount -t hugetlbfs none /dev/hugepages
 echo 24 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
 dpdk-dfe_app -c "axiq_lb enable"

Usage - iq_app Tx use case

Default examples use 32KB TX FIFO in DDR

   ./iq-app-tx.sh ./tone_td_3p072Mhz_20ms_4KB1200_2c.bin 
   ./iq-stop.sh

Usage - iq_app Rx use case

Default examples use 128KB RX FIFO in DDR

   ./iq-app-rx.sh ./iq-data.bin
   ./iq-stop.sh
   kill <iq_streamer PID>
