System crash on snapdragon 820

Hi everyone,

We are currently facing a crash of the whole system, when launching our application.
We are using a Snapdragon 820 pro SOM on a custom board, with linux linaro qcomlt kernel version 4.14.
We don’t get any errors from the system, except the bootloader starting sequence, which doesn’t even reach LK.

We checked all voltage on our board and our SOM and we didn’t catch any drop.
We will also check if there is an over consumption of power.

If this was caused from a software level, we should have logs from the kernel right?
This crash happens sometimes when launching the application or when loading some data in memory.

Thanks in advance,
