No dump from streamline lwi script combo

Hello,


I am trying to profile a Unity game on Android. Have followed the Unity specific steps for dev and built the apk.

Then I try to run the lwi script with these params -

python3 lwi_me.py --lwi-mode=capture --lwi-fps-threshold=20 -v --daemon ../../../streamline/bin/arm64/gatord --lwi-out-dir= /mnt/data/Documents/armmobilestudio/frames

I see my debug app and then Select it.

I then go onto starting Streamline for capture. In the meanwhile I check with adb shell "ps -A | grep gator" and it shows the package location where gatord has started -

# ps -A | grep gator                                                                                                                                                                                    
u0_a34       11672  3102   23184   5784 SyS_epoll_wait 754df30660 S gatord

# ps -o COMMAND | grep gator

/data/data/com.company.name/gatord


When Streamline starts I choose midguard (config) as have a T860 on the SoC. It asks me that gatord is running on the system so what do you want to do... I click on advanced and choose the device visible on the screen.

Start Capture

No Data :(

In the meanwhile on the device I see another gatord running -

adb shell "ps -A | grep gator"
u0_a34       26172  3102   25232   5816 SyS_epoll_wait 7cb9572660 S gatord
u0_a34       26374 26172   25168   4348 0          7cb9573188 R gatord


Streamline is unable to capture any data, the app does not automatically start and no dump comes out. Following the procedure from here - https://youtu.be/9_mdAzAx39w

When I press enter on the lwi command window I get this -

Trying to pull LWI local capture from device if there is one

During handling of the above exception, another exception occurred:

I am using this as a reference - developer.arm.com/.../Run-the-script-and-capture-a-Streamline-profile


PS - I can run Streamline standalone and capture data from the device but I wanted to run PA on the captured data
