==Software thermal protection==
===Axel Embedded Linux Kit (XELK)===
In [[Axel_Embedded_Linux_Kit_(XELK)|XELK]], two software thermal protection mechanisms are implemented. Both are based on the processor's temperature sensor. It is worth remembering that maximum junction temperature (also denoted as Tj in the rest of the document) is :*95°C for commercial parts*105°C for extended commercial and industrial and extended commparts*125°C for automotive parts.
At U-Boot level, automatic boot procedure is halted until Tj is smaller than (following temperatures might seem excessively low but they take into account the intrinsic poor precision of the temperature sensor to provide a reasonable safe margin):
