TMS320DM8168: TMS320DM8168 - Thermal Issues.

Part Number: TMS320DM8168

Hi,

We are using TMS320DM8168 Processor with Heat sink  for Audio & Video Capturing and H.264 encoding and Storing.While running the functinality test (Capturing,encoding and storing) at room temperature 25°C within a couple minutes processor temperature reaches around 58°C and board hangs, with Fan used to run for long hours and maintains the processor temperature below 54°C.

The same board (Test Setup, software code & Drivers are same)before 6 months atleat used to run continously at room temperature 25°C for more than 4 hours and observed processor temperature even reaches to around 85°C (without Fan).

Kindly let me know your suggestion and feedback.

Regards,

Vijay Varma
