HIgh temperature when using UART on Viola Plus

Dear Community,

I connected to my Viola Plus an USB-TTL(3,3V) cable like mentioned on here. Everything works just fine when I run minicom. The thing is that I have notice how the temperature on the Colibri iMX8X has become much higher than it usually is, when the UART is plugged to the extension connector. My question is, is this normal or should something be done?

Kind regards.

Hi @alex.tx,
thank you very much for your answer. Looks like I was worring about nothing, I cheched the temperature using the command you mentioned above and the temperature isn’t higher than 80°C.
Kind regards.

What is an actual temperature? You can get it by cat /sys/devices/virtual/thermal/thermal_zone0/temp command. The output is in 1000ths of degrees Celsius. Nothing to worry about if temperature is below 80C.
