I am seeing these two independent issues on different apps in WP. The performance of the app(the speed at which data is transferred on CAN) varies based on whether logs are enabled using logread -f command on a terminal. I am seeing better performance when logread -f | grep appName command is used…

Thanks for replying @jyijyi . Yes, logread will not be enabled in production. While debugging the app we are seeing better performance when logread is used. After maximizing the cpushare and priority, no performance improvement is observed. I have tried running the required application in stand-al…

it does not quite make sense that performance will be better if logread is used… Have you run it in standalone native C program? It willl no longer relate to legato, and you can see if it has improvement.

How to run a standalone native C program? Can you please help me with the steps.

you need to download the R9 toolchain and install the .sh file https://source.sierrawireless.com/resources/airprime/software/wp76xx/wp76xx-firmware-release-9-components/#sthash.WPPvRrYH.dpbs

[image] I am getting the above error when I run the script for installing the toolchain. I just downloaded the script and ran ./poky-swi-ext-glibc-x86_64-meta-toolchain-swi-ext-armv7a-neon-toolchain-swi-ext-2.2.3.sh. Am I missing some step before this?

I installed the toolchain in ubuntu 18 successfully, you can try on that
