Apalis TK1 crashes very frequently

Hi,

I started to use Apalis TK1 on a carrier board Ixora.

It cashses very frequently when my system based on GStreamer is running.
Then I made a small script to test it as below.

#!/bin/sh

run() {
	id=$1
	for count in `seq 1 10000`
	do
		python <<EOT
key=$id
a = 1000 * 1000
print "%s: %s" % (key, a)
EOT
	done
}

run 1 &
run 2 &
run 3 &
run 4 &
run 5

The Linux kernel will reboot automatically a minute later after the script run.
I have 3 Apalis TK1 on Ixora and every devices crashes by the script.

The temperature of the heatsink is very high when the kernel reboot.
The high temperature causes it?

My Apalis was installed as the page.

These are used to install.

  • Tegra_Linux_Sample-Root-Filesystem_R21.5.0_armhf.tbz2
  • Apalis_TK1_LinuxImageV2.6.1Beta1_20160929.tar.bz2
  • JetPack-L4T-2.3-linux-x64.run

Let me know how to avoid the crash!
Thanks in advance.

Heatsink alone is not enough to cool Apalis TK1 under heavy load, you also need a fan.
You’ll also need to modify your Ixora according to http://docs.toradex.com/103358-apalis-tk1-errata.pdf to make sure it can provide enough power

Thank you for your reply, dominik.tx.
I understand that I need to attach a fan or/and modify the register acoording to the errata.

Yes, preferably attach a fan and modify the resistor, but for a lot of use cases fan is enough. We believe that upcoming Apalis TK1 1.1 revision will no longer require a shunt resistor of lower value, but a fan or a custom cooling solution capable of dissipating enough power will be required.
