`openssl speed` causes reset on a13-som-512 during SHA1 hash

[thom_nic]

I'm using stock image A13-OLinuXino-bullseye-minimal-20220321-223544.img.7z

If I run `openssl speed` I repeatedly get a hard reset during sha1 hashes.  There is no panic or core dump printed to the console.  What could be causing this??

Looks like either insufficient power supply or overheating to me.

How do you power the board? Where exactly do you apply the power supply? What is the power rating of your power supply?

Hey thanks very much for the reply - I didn't get a notification but just happened to check back on this forum because it seems we are indeed seeing high power draw on the board.  I need to gather more information regarding the hardware design.

Well the schematics are here:

The big thing about A13-SOM is that it has no PMU, no AXP209.
