NetHAT temperature question
I'm using NetHAT module with STM32MP157C-DK2 board which has a port compatible with raspberry pi shields.
After a few minutes plugging in the module, it accumulates considerable heat even though it doesn't perform anything. I don't know how to describe it but it's  quiet hot.
The temperature is localized over the netx52 chip and also over the GPIO pins at a lesser extent.
The demo seems to works fine other than the fact that I got a bus error after a few seconds because I haven't configured a master yet.

Since I'm not using a RaspberryPi I was just wondering if this was normal behaviour, or could it be caused by bad gpio configuration of my board

Hi there,

the technical paper about netX52 chip you will find here: https://kb.hilscher.com/pages/viewpage.a...d=84879912

It is consumung 1.5W of power during normal operation. And yes it is getting quite hot since the chip container the 2 PHYs for the two Ethernet ports. These two consume the most of the power. The Tj junction temperature is 125°C and without heat sink you can operate it in ambient air temperature of up to +70°C.

So no worries.

You never fail until you stop trying.“, Albert Einstein (1879 - 1955)
