IMX6Solox A9 locks up after running a QT application

[niranjanbc]

Hi

I have a QT application written for our product running on A9 (linux) and MQX running on M4(from QSPI NOR Flash)

when I run QT application, A9 locks up at certain point. I dont see any kernel panic message or nothing.

if I disable M4 and then run QT Application on A9, i dont see lock up problem.

anyone seen this kind of behaviour. do you got any solution or suggestion for this problem, please help me.

thanks

what bsp version do you use? and where did the QT lock??

problem resolved, i see A9 and m4 were trying to access same uart ports, which was creating issue.
