Hello @jasonshao, did you manage to fix your problem? I observe the same issue. Unfortunately advice by @kunalkotecha1 did not help.

[kunalkotecha1]

Hi jasonshao,

From the logs you shared, your regression test is also  failing. It seems you have started the "tee-supplicant" process in background manually. However, according to me the kernel will automatically start this service, we no need to start it manually. Manually starting this again can lead to crash. Can you please boot the kernel and then directly test the "xtest" application? If this regression test passes then continue with hello world application.

Regards,

Kunal
